Rookie campers may think that, like sleeping bags, sleeping mats are all pretty much the same - but in fact they vary enormously. From simple foam rollout mats to highly engineered insulated options for trekking in winter, sleeping mats are as varied in style and price as coats, tents and boots.
Arguably, your sleeping mat is one of the most important things to get right in your camping kit. Before you start getting into portable coffee makers and foldable solar panels, your sleep setup comes first, and a good mat is an essential component of a restful night's sleep.
It immensely improves your comfort and insulates your sleeping body from the cold ground. Not to mention, aesthetically, a nice mat can really tie the whole room – or tent – together.

When buying a sleeping mat, you need to consider your body, your sleeping habits, and of course, your budget. Like every area of outdoor gear, the ceiling for both price and quality is staggeringly high. But luckily, there are some very respectable mats with reasonable prices out there. You just need a group of dedicated campers to try them all out and let you know what's what. And that's where we come in.

The best sleeping mats reviewed:
The Sea to Summit Ether Light XR strikes an excellent balance between weight, durability, comfort and warmth.
An R-value of 4.1 is a solid rating for three-season use, with the internal ThermalCore insulation providing a toasty warmth boost.
Yet the mat is still lightweight and compact, clocking in at 547g (regular version, including storage bag), and packing down to a compact cylinder sized 20x11cm, which is slightly smaller than many competing products.
The 30-denier and 40-denier nylon materials feel simultaneously lightweight yet reasonably robust, while the slightly-tapered mummy shape is refined for lightness.
There’s a quilted surface with a textured, criss-crossing, grid-like pattern called Air Sprung Cells. We found it very comfortable and cosy (although possibly a bit bobbly).
The 55cm width and 10cm thickness are particularly impressive, offering extra room and insulation than other brands’ offerings, but the 183cm length is pretty standard.
Inflation and deflation of the Ether Light XR are seamless too, courtesy of Sea to Summit’s high-tech XPRESS valve and Airstream Pump sack. It took us three full sacks of air and barely a minute to fully inflate – efficient stuff.
Overall, this is a top-tier mat for three-season, multi-day adventures.

The biggest selling point of the Big Agnes Rapide SL Insulated mat is its price. It has the credentials and features to be closer to £200, so at £150 it represents excellent value for money.
The R-value of 4.8 is particularly impressive, out-performing more expensive alternatives. The Rapide is more than suited to 3-season adventuring and only just falls short of suitability for winter.
The Rapid SL’s rectangular profile (183x51cm) adds roominess compared to mummy-tapered pads, and the 10.8cm-thick vertical baffles deliver good levels of comfort, support and stability.
Inflation and deflation are very straight-forward too, via the included pump sack and high-tech dual valve. On our first attempt, it only took a few minutes and four loads of the pump sack to fully inflate.
The only real drawback of the Rapide SL is its weight. It clocks in at 607g (including mat, pump sack, storage bag and repair kit), which is slightly heftier than its competitors.
The Big Agnes Rapide SL isn't the best option for fast and light adventures, but for general camping it's an excellent, budget-friendly all-rounder.

Pros
- Great value for money
- Excellent R-value
- Impressive warmth
- Rectangular profile
- Thicker than average
- Efficient inflation-deflation system
- Good comfort and support
Cons
- Heavier than ideal
- Feels a tad narrow

The Nemo Tensor Elite is a sleeping mat that's all about saving grams – it's a mighty small unit, not much bigger than a Coke can, weighing a featherlight 326g.
The R-value is 2.4, which isn't 3-season suitable, but it’s ideal for spring and summer adventures.
It delivers surprisingly impressive comfort, stable cushioning and well-executed features. The shape is a tapered mummy, which feels a tad narrow, thin and lacking in spaciousness, but ultimately does the job, and comfort levels are good courtesy of Nemo’s grid-like Apex baffles.
We particularly loved the inflation-deflation system. The pump sack is quick and efficient (only 2.5 sets to fully inflate) while the Laylow valve has a really clever micro-adjustment system for air pressure.
This isn't the most rugged option on the market, but it does come with Nemo’s Lifetime Warranty.
Overall, the Nemo Tensor Elite is an amazingly light sleeping mat with surprisingly impressive comfort levels, ideal for gram-saving ultralight enthusiasts.

Pros
- Amazingly lightweight
- Superb weight-saving innovation
- Good levels of comfort
- Incredibly compact
- Well-executed features
- Vortex Pump Sack is excellent
Cons
- Not that warm
- Only suitable for two-seasons
- Only 2.4 R-value
- Expensive
- Slightly narrow
- Not very spacious
RRP: | £200 / $199.95 (short mummy), £230 / $229.95 (regular mummy) |
Thickness: | 8cm |
Packed size: | 15x9cm |
Weight: | 326g / 11.5oz (including storage bag, pump sack and Velcro strap) |

Dimensions: | 183x51cm (LxW) |
The Mountain Equipment Mirrostat 7.0 delivers a superb warmth-to-weight ratio.
You get an official R-value rating of 4.5, which for some campers will be suitable for winter camping in zero or sub-zero temperatures, yet the weight is only 530g (regular size, including storage bag and repair kit).
The mat has a rectangular profile, not a tapered mummy shape. It's particularly long (190cm), which is about 7cm more than most other mats, thus making it suitable for taller campers.
I measured the packed down Mirrostat at 28x12cm, making it longer and thinner than most alternatives. Unlike some brands, Mountain Equipment have provided a spacious bag, which makes it much easier to pack away the mat in the morning – a nice touch.
The 51cm width is pretty standard, if not slightly narrow, but the raised bathtub-style sides effectively prevent you sliding off.
There's one aspect which might divide opinion. The sleeping surface’s vertical baffles will feel a bit ridgy to some campers, but others will love the comfort levels.
The pad benefits from spot welded construction for extra durability. However, it’s perhaps less robust than some of the competition, so it’s worth handling with care.
Overall, the Mountain Equipment Mirrostat 7.0 is ideal for lightweight end-of-season adventures, providing a superb amount of warmth for its weight.
Read our Mountain Equipment Mirrostat 7.0 review for more info.
Pros
- Superb warmth-to-weight ratio
- 4.5 R-value
- 9cm thickness
- Longer than average
- Only 530g
Cons
- Expensive
- Slightly narrow
- Vertical baffles feel a bit ridgy
- Slower to inflate than many others
RRP: | £200 (Regular), £220 (Long) |
Thickness: | 9cm |
Packed size: | 28x12cm |
Weight: | 530g / 1.2lbs (including storage bag, pump sack and repair kit) |
Material: | 20-denier recycled polyester |
R-Value: | 4.5 |
Dimensions: | 190x51cm (LxW) |
The Rab Ultrasphere 4.5 is one of the best sleeping mats if you're looking for 3-season levels of warmth at the lowest weight and most compact size.
It delivers a competitive R-value of 4.3 (not 4.5, confusingly), but weighs just 463g (including pump sack, storage bag and repair kit) and packs down incredibly small (16x9cm).
The toasty warmth is achieved through two layers of heat-reflective TILT (Thermo Ionic Lining Technology), which works like an emergency foil blanket to reflect heat back towards your body.
With a 4.3 R-value, I'd put a lot of faith in its insulating ability for 3-season use, though I'd opt for something with a higher value for the cold depths of winter.It's made from ultralight 20-denier polyester fabric, with a minimalist, mummy-style cut. Some people might prefer a wider mat – but this is the downside of it being ultralight.
Comfort levels are high, thanks to the horizontal baffles, while inflating and deflating via the pump sack and modern valve system is straight-forward enough.
Again, due to how lightweight this mat is, durability may be an issue in the long term – though we’re yet to have any qualms ourselves.
Overall, the Rab Ultrasphere 4.5 is an ultralight, super-compact sleeping mat with a superb warmth-to-weight ratio – perfect for fast and light adventures.
Read our Rab Ultrasphere 4.5 review for more info.
Pros
- Ultralight and compact
- Superb warmth-to-weight ratio
- Impressive R-value
- Good price
Cons
- Quite narrow
- Not the thickest (only 8cm)
- Questions marks over long-term durability
- Pump sack is a little slower than some competitirs
RRP: | £170 (regular), £180 (long wide) |
Dimensions (LxW): | 183x51cm |
Thickness: | 8cm |
Packed Size: | 16x9cm |
Weight: | 463g / 1lb (including storage bag, pump sack and repair kit) |
Material: | 20-denier recycled polyester |
R-value: | 4.3 |
The Therm-a-Rest NeoLoft has an unrivalled level of comfort. This mat is so thick (12cm), plush, warm (R-value of 4.7) and cosy it’s almost like a portable, camping version of the traditional airbed you might sleep on when visiting a friend’s house.
The downside of this is that it's very expensive and heavier than ideal (928g, including storage bag, pump sack and repair kit).
The super-wide profile (66cm) is certainly luxurious, but it might be too big for your tent. The packed-away size (27x14cm) is chunkier than most, so this is a good option if space isn't a concern.
It achieves an R-value of 4.7, which is almost suitable for winter. It's more than enough for 3-season use, providing effective insulation from the ground.
One standout feature is the huge, 54-litre, seam-sealed pump sack, which fills up naturally, with very minimal effort required. There's absolutely no risk of moisture from breath getting into the pad, which can lead to issues with mould in the long run.
The Therm-a-Rest NeoLoft is a super-thick, ultra-plush sleeping mat with unrivalled levels of comfort – perfect for car camping, where space and weight isn't a concern.

Pros
- Unrivalled comfort levels
- Very wide sleeping surface
- Comfortable horizontal baffles
- Excellent warmth and 4.7 R-value
Cons
- Very heavy and chunky packed-away size
- Possibly too big for some one-person tents
- Expensive
- Pump sack to mat valve connection is a little fiddly

We've been using this sleeping mat for nearly a year and it's been tremendous. Near Zero is a reasonably small American outdoor brand that produces excellent value, high-performance kit that is designed to make wild camping and backpacking more accessible to more people.
Its insulated sleeping mat strikes a great balance between comfort and weight. It insulates well and is a good size (186cm is slightly longer than other regular-sized mats).
We liked how compact it is too, despite not being the lightest mat we've tested. So far for us it's held up well and is showing no signs of wear or tear.

Pros
- Impressive warmth-to-weight
- Quite durable
- Fantastic value
- Available in regular and wide
Cons
- Not as lightweight as some rivals
Dimensions | 186 x 55 x 8cm (M size) |
Weight | 652g (Regular size) |
Packed size | 20 x 10cm (Regular size) |
Material | 20D nylon |
R-value | 3.7 |
As a first inflatable sleeping mat this is our pick. It's a sleeping mat we've used several times and have been perfectly comfortable using.
At 650g and packing down to 27 x 14cm it's reasonably compact for a self-inflating sleeping mat, and despite being low cost, is pretty durable too.
That said, it's not the warmest mat for its size (the Therm-a-Rest ProLite Plus below is noticeably warmer) and is best used for late spring through to early autumn.
Pros
- Reasonably lightweight and compact for a self-inflating mat
- Quite durable
- Fantastic value
Cons
- Not the warmest
Dimensions | 183 x 51 x 3cm |
Weight | 650g |

The lightweight and packable Exped Ultra 3-season inflatable mat has impressed us for its performance and eco-credentials. It's become our go-to mat for most hiking trips. It uses Bluesign-certified synthetic insulation and recycled 20D ripstop polyester fabric; the mat is even certified carbon neutral by myclimate.org.
The Ultra 3R is comprised of head-to-toe air chambers that provide a pliable, cushioned sleeping surface and – more importantly – excellent insulation from the ground. This is thanks to Exped's proprietary Symnat Texpedloft technology. Is that a silly name? Perhaps. But this sleeping mat is seriously good at keeping you at a safe and comfortable temperature throughout chilly nights.
Pros
- Ultralight for long hikes
- Sustainable construction
- Pump bag included for easy inflation
- Available in several sizes and shapes
Cons
- Slightly delicate construction demands care
Dimensions | 183 x 52 x 7cm (M size) |
Weight | 465g (M size) |
Packed size | 23 x 11cm (M size) |

The Vango Thermocore XPD is a belter of a winter sleeping mat, coming in at a very reasonable RRP of £140 but found in retail outlets around £120.
At 10cm deep, it offers impressive comfort, especially for side sleepers - and it prevented my hips from sinking too close to the ground which happened a lot with my old roll mat. The addition of a crinkly, silver thermal layer helps to reflect heat, making it an excellent option for colder conditions - it has an impressive R value of 5.6, make it a true 4 season trekking mat.
The generous 195 cm length and 58 cm width (for the regular size) offer plenty of space to stretch out, so this would suit the vast majority of users.
However, it’s worth noting that the small size of the inflation bag means blowing the thing up takes a while, so those who suffer from patience deficit might find it a bit tedious. Additionally, the valve can be a little sticky when trying to detach the inflate bag, which led to a few frustrating attempts before I was successful. Once you've got the knack, however, it becomes easy enough.
In terms of comfort, the dimple texture, along with the aforementioned thickness, is great. It helps prevent you from sliding off the mat in your sleeping bag, ensuring you don't end up on the cold, hard ground. While generally quiet, the mat's internal layers can make a slight crinkling sound, which may be noticeable for more restless sleepers. A pair of earplugs should be in your camping kit anyway! Overall, though, I had a great couple of night's sleep.
Deflation and packing down are quick and easy, with the mat compressing down to a compact 22 x 13 cm (packed size), making it a great choice for backpackers looking to save space. The mat is also relatively lightweight, weighing 740 grams for the regular size, which for 10 cm depth makes it lighter than many competitors in the same category.
Pros
- Very comfortable and thick
- High R value for winter nights
- Pump bag included
- Packs down small
Cons
- Takes a while to inflate
- Can sound slightly crinkly
Dimensions | 195 x 58cm x 10cm |
Weight | 740g |
Packed size | 22 x 13cm |
Material | 20D Recycled Nylon Fabric, Ultralight TPU Membrane, Thermal Reflective Film |
R-value | 5.6 |

A great combination of weight, pack size and warmth, and at a good price. The Therm-a-Rest ProLite Plus self-inflating might require some manual assistance, but the comfort provided is good for this kind of mat.
The highlight of this mat is the WingLock valve, a high-performance valve with an increased airflow for rapid inflation or deflation. Although, with the ProLite Plus' expanding foam core, you'll only need to access the valve if you want to top off the self-inflation for your ideal level of firmness.
This little bit of wiggle room for personal taste is what makes Therm-a-Rest a go-to choice for experienced campers.
Pros
- Compressible foam allows easy packing
- Efficient design gives good insulation for weight
- Convenient self-inflating function
Cons
- Tapered shape won't suit all campers
- Can still require some manual inflation
Dimensions | 183 x 51 x 3.8cm |
Weight | 650g |
Packed size | 28 x 17cm |
Material | 50D polyester w/ urethane foam core |
R-value | 3.2 |

We put this pricey but technical sleeping mat to the test in the Cairngorms during winter. The Tensor Extreme Conditions boasts an impressive R-value of 8.5, making it one of the warmest backpacking mats available.
This warmth is achieved with four layers of Thermal Mirror metallised film within Nemo’s Apex baffle design, adhering to the ASTM F3340 standard for accuracy.
Comfort is impressive too with its 9cm deep cushioning, which offers a relatively luxurious sleeping experience uncommon in lightweight mats. Despite its high R-value and thick cushioning, the Tensor EC weighs under half a kilogram, thanks to the lightweight Thermal Mirror film.
The mat is easy to inflate with the Vortex pump sack, taking fewer than four inflations, and deflates quickly with the updated Laylow valve. Its 40D nylon underside is puncture-resistant, while the 20D nylon top provides a soft, quiet sleep surface.

Pros
- Well insulated
- Deep and cushioned
- Surprisingly lightweight
Cons
- Overkill for most users
Dimensions | 183 x 51 x 8.9cm (Regular size) |
Weight | 587g (Regular size) |
Packed size | 25.5 x 10cm |
Material | Bluesign-approved 40D nylon base and 20D top |

Astoundingly lightweight and packable, albeit not the warmest, the Inertia Ozone relies on your sleeping bag to provide most of the insulation, leaving gaps in the frame of the mat in which the bag can loft.
The combination of air and foam makes this a superb regulator for summer camp trips and a fine all-rounder for those who like to keep it ultralight. You won't find a mat that's easier to carry with you, though this does come with a small compromise on comfort.
You may not get the lush padding of the Polarshield, but we think the trade-off is worthwhile on a hot day or a light trek.
Pros
- Ultralight with tiny pack size
- Air pockets create loft for your sleeping bag
- Compatible with Klymit USB Rechargeable Pump
Cons
- Doesn't offer standalone insulation
Dimensions | 183 x 55 x 4cm |
Weight | 369g |

Light, tough and exceptionally budget-friendly, this Multimat Camper 8 mat is suited to warmer conditions and predictably comfortable pitching locations where its lack of cushioning and insulation won't be missed.
Not everyone is pitching up on the north face of Snowdon. In our experience, the majority of pitched tents reside in flat, grassy valleys and meadows. Festivals too. If this sounds like your camping context, then the Multimat Camper 8 is an ideal choice.
Pros
- Fantastic price
- 3-season rating
- Constructed in the UK
Cons
- Less insulation than inflatable mats

What to look for in a sleeping mat

A good sleeping mat is essential for a comfortable night’s sleep in the great outdoors. Whether you're a casual campsite tourist, a hardcore wild camper or a long-distance thru-hiker, choosing the right mat can make a huge difference. This guide will help you understand the key factors to consider when purchasing a camping sleeping mat.
Type
Mats fall into one of three categories:
Foam mats are lightweight, cheaper and weather-resistant, but provide minimum cushioning and are bulky to carry. They are not very thick and, in terms of comfort, they are far inferior to inflatable mats. But their real benefit is that they are effectively indestructible.
While an inflatable mat can easily be punctured, a foam mat is utterly bombproof – hence they are often favoured by long-distance hikers who need reliable, robust kit that will last for months on trail.
Self-inflating mats contain foam that expands and pulls in air when the valve is opened, thus self-inflating. This foam traps air, providing insulation and cushioning.
They come in various shapes and sizes to balance insulation, packability and comfort. Pros include minimal inflation effort, lightweight designs and an excellent warmth-to-weight ratio.
However, they tend to be heavier, bulkier, pricier and less cushioned than regular inflatable mats, and can be prone to punctures—though they are easily repaired. You perhaps need to take the term “self-inflating” with a pinch of salt too.
They don’t always inflate particularly quickly or fully, and may require manual topping up.
Inflatable air-filled mats are like compact air beds for adventurers. Generally-speaking, they are the highest quality and most premium option for wild campers, offering the best balance between comfort, weight and all-round performance.
Inflatable air-filled mats require manual inflation, usually by blowing into the valve with your mouth or using a “pump sack” (a bag-like tool which fills with air, attaches to the valve and then inflates the mat).
Compared to self-inflating mats, regular inflatable air-filled mats are lighter, more packable, thicker and more comfortable, particularly because the firmness of your mat can be fine-tuned to your preference. However unless they have some kind of insulation inside, they can be cold.
Consequently, many mats feature insulation such as down or reflective materials to increase warmth. Other cons of inflatable air-filled mats include the time and effort required to inflate them, and the inherent risk of punctures.
R-value

R-value is a measure of thermal resistance; the higher the R-value, the warmer the mat. As of 2020, a new industry standard was adopted by most brands to standardise the measurement of R-value – the ASTM FF3340-18 R-value standard.
What is a good R-value? It all depends on the weather conditions and temperatures you’ll be camping in. To generalise, an R-value of 1-2 is considered suitable for summer camping in warmer weather, 2-4 is tailored for three-season use from spring to autumn, and 4-6+ is designed for colder weather, with higher values suitable for sub-zero camping.
Weight
A sleeping mat will spend more time being carried in a pack than being slept on, so lighter is better, but toughness can diminish with weight, so there's a balance to be found.
We’d consider a weight of 400g-600g (including accessories such as storage bag and pump sack) as a good target to aim for. 400g or under would be classed as ultralight; 600g+ is starting to get a little heavy, perhaps.
Mat size, shape, length and thickness

Mats from reputable brands often come in different lengths and widths, meaning you can choose one that best suits your body shape. Most campers will be fine with the regular size, but taller or plus-sized campers may prefer a long version, wide version or long-wide version. Anyone particularly short in height may also be able to save weight by selecting a ¾-length mat.
In terms of shape, mats tend to come in two main designs: rectangular or mummy. Rectangular mats provide a bigger overall sleeping surface area, adding versatility and comfort for those who toss and turn at night – but they are usually heavier and bulkier.
Most wild campers, therefore, tend to opt for a mummy-style mat which is tapered towards the foot end to shave off grams and provide a better balance between weight and comfort.
Not all mats come with the same thickness when inflated. The thicker a mat, the more comfortable, warm and insulating it will be; but it’ll be also be a bit heavier and bulkier.
Remember to check a mat’s inflated thickness before purchasing. Side-sleepers will tend to benefit most from a thicker mat, which will help prevent the sleeping surface collapsing inwards under your body weight.
Sleeping surface design

Above anything else, this might be the most important factor in terms of sleeping mat comfort. It’s a very personal, subjective thing too – will you prefer the feel of vertical baffles or horizontal ones, or will a quilted, textured surface suit you better?
Therefore, it’s always best to try before you buy in a shop, if you can. Horizontal baffles, which run at 90-degrees to the mat length, are billed as providing a stable sleeping surface with good weight distribution.
Vertical baffles, which run parallel to the mat length, create long air channels and, according to some, work better for side sleepers. Alternatively some campers favour a quilted surface, which has a contoured, grid-like texture rather than baffles. But, ultimately, it all comes down to personal preference.
Packed size
Mats with smaller packed sizes are easier to fit into a rucksack along with your other camping gear. Warmer mats tend to be bulkier, so really compact mats are best saved for summer.
Durability and materials

The type, cut and thickness of the materials used in a sleeping mat will affect how durable, tough and sturdy it is in the long-term. Nylon and polyester are common – and it’s also worth checking the denier rating of the materials used. The higher the denier, the more rugged it’ll be.
Repairability
Self-inflating and inflatable mats become unusable if punctured, so usually come with some kind of repair kit. Foam mats are far more resilient and continue to offer insulation even when wet.
Inflation, deflation, pump sacks and valves
Some old school sleeping mats are inflated by mouth, like a balloon, meaning you literally have to place your lips over the inflation valve and blow in.
But this method is largely out-dated now, partly for hygiene reasons and partly because this approach adds moisture to the inside of the mat, which can cause internal damage and deterioration over time.
These days most mats come with a “pump sack” – a bespoke bag with an integrated hose and nozzle that is used to inflate your mat. The pump sack looks a little like a dry bag or sleeping bag storage bag, but has a specialised nozzle at its base.

This nozzle attaches to the valve of your sleeping mat. The pump sack then fills with air, either by gently blowing into it from a distance or angling it towards the wind so that it fills up naturally. You can then close the sack and roll or compress it downwards, thus forcing air through the nozzle to inflate your sleeping mat. It’s an efficient, convenient system.
In terms of the inflation-deflation valves on your sleeping mat, it’s best to opt for a mat with a high-tech, modern valve. These valves have a clever design, usually with two caps layered over one hole. When you open the first cap, the valve is one-way only, meaning no air can flow outwards, but air can flow inwards.
This ensures you can efficiently inflate the mat without any risk of deflation or leakage via air flowing outwards. After your camp, opening both caps will enable the mat to deflate. Some mats also have an additional micro-adjustment system, which enables you to fine-tune the air pressure to your preference.
