Sleeping pads are essential to camping as we all want a comfortable night’s sleep. Nothing is worse than waking up during the night feeling uncomfortable and cold. You can hardly move in the morning as your sleeping pad has not offered the protection or comfort you thought it would.
Either mummy or rectangle shape. The length should be proportional to height, avoiding body parts touching the ground. Size ranges from 4.4 to 6.56 ft long—regular width 2ft to a double 4.33 ft. They are thermally insulated to protect against the cold ground. R-value R1 – R6 plus; the higher the rating, the more excellent insulation. To have a comfortable night’s sleep, a depth of 5 cm – 10 cm, especially if a side sleeper.
So many sleeping pads are available that deciding which is best for you can be confusing. What may be comfortable for you may not be suitable for another person. Plus, if you camp during different times of the year, you may need more than one sleeping pad.
What are sleeping pads, and why do you need them?
Sleeping pads are known as SIMs (self-inflating mats) or sleeping mats. They are thermal mats that improve comfort levels whilst camping. They are essential to help reduce heat loss from the body whilst sleeping.
Sleeping pads can either be mummy or rectangle and the same shape as a sleeping bag, single or double. Several different styles are designed for comfort, backpacking and wild camping.
There are two types of sleeping pads, either closed or open-cell pads.
Closed-cell is a thermal foam base usually placed underneath an open-cell sleeping pad to help increase thermal insulation, typically used for wild or backpacking. They are not very thick and not comfortable to sleep on directly.
Open-cell sleeping pads are either foam and air or fully air-filled. Thickness can vary from 3cm to 15cm. Combining air and foam is not very comfortable to sleep on directly but adds good insulation. In contrast, a complete air sleeping pad can be adjusted to suit the users’ comfort levels.
Open-cell sleeping mats are often self-inflating or inflated by an electrical, battery-operated pump. Inflation bags are a quick and easy way to inflate for backpacking or wild camping rather than blow up manually.
Prices can range from £4.99 – £300. Higher-costing sleeping pads will have a higher R-value, providing more thermal insulation. You may only want a lower-budget sleeping pad for summer family camping compared to wild or colder-season camping.
We use a budget closed-cell sleeping mat with foam on one side and aluminium foil on the opposite side for our family camping trips. It is bulky for transporting as you cannot condense it down. We combine it with an open-cell pad for comfort 10cm thick and a season 4 Colemans Basalt sleeping bag. Combining all three provides good thermal insulation against the cold.
It does not matter how much you spend on a sleeping pad so long as it works efficiently. However, if you have an open cell sleeping pad, it is vital to understand how to look after it. Otherwise, you will see marks on the outer layer, which will be mould forming inside. Once this happens, it is not possible to remove it without damaging its effectiveness.
Before buying an open-cell sleeping pad, please read our article about how to avoid damage and mould forming inside. This may change your mind, and you decide on a closed-cell sleeping pad instead.

There are several reasons why a sleeping pad is essential for camping. Not only to help keep you warm but also to protect your sleeping bag. A sleeping bag is often overlooked, and we don’t often think about what we must do to maintain it correctly whilst camping. You can do several simple things during your trip to prolong the life of your sleeping bag and help retain the heat. Avoid having to replace it after a year. Our simple guide will help you save money and keep warm at night.
What length and width are sleeping pads?
Sleeping pads are available in various sizes, varying depending on the brand. They are small, regular and large. The width of sleeping pads is standard, large, single and double. A large single is ideal if you like to move around in your sleep or use a pod sleeping bag instead of a mummy or rectangular.
What is the width of a sleeping pad?
- Regular single – 51 cm – 63 cm / 1.67 feet – 2 feet
- Large single – 76 cm – 100 cm / 2.50 feet – 3.28 feet
- Double – 130 cam = 132 cm / 4.26 feet – 4.32 feet
Mummy and rectangular sleeping pad length guide
To determine a suitable length, combine your height and additional pillow space. You will avoid curling up to keep your pillow on your sleeping pad. Avoid touching the ground with any part of your body.
Mummy / Rectangular | Length | Body length |
---|---|---|
Small | 120 cm / 4 feet 140 cm / 4.6 feet | Under 4.6 feet |
Regular | 160 cm / 5.24 feet 180 cm / 5.90 feet 182 cm / 5.97 feet 183 cm / 6 feet | Standard size up to 6 feet tall |
Large | 185 cm / 6.06 feet 195 cm / 6.40 feet 200 cm / 6.56 feet | Over 6 feet |
To help keep your pillow in place and increase the warmth rating, you can use a sleeping pad cover, like an undersheet on a bed. They have a strap underneath to keep them in place and a small pocket to hold your pillow during the night. I use the Klymit Unisex cover, but it is only available for rectangle sleeping pads.
Sleeping pads: Understanding R-values
R-values determine a pad’s suitability for specific seasons. Higher R-values offer better protection against cold ground. These are thermal ratings and make them ideal for winter camping.
- R1 to R2 is suitable for summer – Temperature range -32 °F / 0 °C
- R2 to R4 for cold sleepers in winter – Temperature range – 20 °F / -6.6 °C
- R4 to R6 for winter camping -Temperature range – 0 °F / -17.78 °C
- R6 Plus for extreme cold – Temperature range – Less than 0 °F
R2 – R6 is ideal for cold sleepers.
Pros and cons of sleeping pads: Closed and open-cell
Closed-cell sleeping pads
Closed-cell sleeping pads vary in their R-value. If you are family camping, you do not need a high rating as you will probably have a camping cot or air bed. Placing a closed-cell pad underneath your air bed will help insulate as air beds do not have R-values ratings.
Prices range from £4.99 – £60
Pros | Cons |

Waterproof | Not comfortable to sleep on directly |
Durable | Bulky for transporting – rolled or foldable |
Ideal for placing under an open-cell pad or air mattress | Not suitable for side sleepers if there is no other sleeping pad |
Some have indents that can trap air that will gradually warm during usage. | Need an additional sleeping pad to improve comfort level |

Open-cell sleeping pads
There are three types of open-cell sleeping pads
- Air and foam – self-inflating – Cost £25 – £109

Is there a weight limit for sleeping pads? Expert confirmed
On average, there are no weight limits for sleeping pads. However, NEMO has confirmed their general weight limit is 136kg / 300lbs / 21 stone. Therm-a-rest has confirmed that there is no weight limit on their sleeping pads.
Bodyweight must be disturbed evenly across the sleeping pad to avoid touching the ground. If a person places all their weight onto their knee or elbow, body weight won’t be evenly distributed, resulting in direct contact with the ground.
How do self-inflating valves work?
Self-inflating valves on sleeping pads allow air to be drawn into the pad when the valve opens. Air will fill the air pockets between the foam., However, you must set up at least 2 hours before bed. Close the valve once complete.
If the sleeping pad does not inflate sufficiently or fast enough during the time frame, it can be manually inflated by blowing into the value. To avoid air escaping, you must close the valve between breaths.
Deflating a self-inflating sleeping pad is a bit of a pain. Because they are self-inflating when deflating, keeping the pressure on the pad is important to avoid inflating via the valve. As soon as it is fully rolled or folded, close the valve. Keep a band handy to wrap around the folded sleeping pad for ease of playing in a carry bag.
Is a sleeping pad suitable for side sleepers?
A comfortable sleeping pad for a side sleeper is between 5cm and 10cm thick. My sleeping pad is 10cm thick, offering comfort and cushioning for my hip and shoulder. Sleeping pads can be inflated fully or deflated, depending on your comfort levels.
Thickness matters
Look for sleeping pads with thicker cushioning, as they provide better support for your hips and shoulders when you’re on your side. Consider pads at least 2 inches (5cm) or thicker for side sleeping comfort.
Material choice
Opt for pads made from memory foam or self-inflating foam. They conform to your body’s shape, reducing pressure points.
Inflatable pads with adjustable firmness can also work well if you find the right level of support.
Size and shape
Consider the size of the pad. As a side sleeper, you will benefit from wider pads to prevent your arms from falling off the edge.
Some pads have contoured shapes designed to cradle your body, which can be comfortable for side sleeping.
Could you test it out before you buy it?
Don’t be embarrassed about testing a sleeping pad out before you buy. Camping stores have fully inflated sleeping pads; they are there so you can visually see their depth. Please test it out before purchasing and ensure you are comfortable on your side.
