With that being said, we can start our review. A Sleeping mat is one of the tools that you have to put on your outdoor equipment list. But, since there are many types of sleeping mats that you can find it on the market, how to know which one to choose?

It is a good product for any outdoor activity, more precisely, for light weather conditions like those trips in late spring and hot summer nights. You can also use it for your scouting activities. It offers a great comfort too, and you can buy it for an affordable price.

As you continue to read the chapters below, you will decide if this Sea to Summit Ultra-Light Mat matches your needs and if it is a perfect choice when compared to the alternative products.



This Sea to summit sleeping mat is part of the ultra light series that packs in minimum volume and minimal weight. The air sprung cells are contributing to this feature, while maintaining the support of the mat. Comparing to air mats with baffles or tubes, this sleeping mat is lighter, therefore more suitable for your backpacking gear.

However, what’s impressive is that the pressure support it is providing is also better than the tube mats. It is the only type of mat in which every individual cell could absorb individually the pressure without distributing it to the closest cell. Having this in mind, we definitely recommend this sleeping mat for your next backpacking trip.

This sleeping mat is also pretty thin which is why we don’t recommend it for rocky terrains. However, it is perfect for flat surfaces. Nevertheless, most air sleeping mats are not recommended for rocky terrains and the ones that are don’t last a long time. Because of its thickness, we recommend this sleeping mat for stomach and back sleepers. However, for the side sleepers, it might feel a bit uncomfortable depending on the ground and your own preferences.

Design and durability

The inner design of the Sea to Summit sleeping mat is responsible for its remarkable features that are incomparable to other products on the market. Having this in mind, the most important feature this Sea to Summit sleeping mat possesses is the Air sprung cells. The air sprung cells are allowing the user a better support and they are making sure you don’t end up touching the ground with your body. They do so, by copying the individual coil system in sprung mattresses.

This means that the pressure that your body is making when sleeping on the mat is distributed evenly throughout the entire mat. Even more, the pressure which is applied to one air sprung cell don’t affect other cells. For this reason, the weight is distributed evenly and you are left with a high quality mat and a good night’s sleep.

The manufacturing technology Sea to Summit is using in the manufacturing process of this sleeping mat is aeronautical grade, which means that it is a highly durable product that you are going to use for years to come. Mouth inflation is usually being avoided by the sleeping mats manufacturers since there is a risk from internal mold growth. When you are inflating the mat, you are letting inside a moist and bacteria rich air which over time could lead to mold growth that could infect you if used continuously.

However, the Sea to Summit are using a specific design that is preventing this process. They are using liquid anti-microbial treatment in the form of TPU bonds, that is sticking to the shell of the fabric and is creating a protective layer that is acting as a barrier between the bacteria and the shell of the fabric. This is allowing you to use the mat for a long time, without the risk of growing mold inside and having to get rid of it after a while.


The Sea to Summit sleeping mat is made from high quality nylon material, more specifically 40 denier ripstop fabric which is contributing to the lightness of it. However, this material is also very durable and it is somewhat resistant to damage. Even though these features might come very useful in warm weather conditions, the insulation is not one of them. Its thin material, is usually making the users doubt whether it is going to get punctured or not.

However, as long as you use it on the leaves or dirt, you have nothing to worry about. It will serve you for many wilderness trips to come. The thinness of the material also means that you would be nice and warm, but only if the ground underneath is warm. When the temperatures drop, you will need a different type of material with heavier insulation properties.

Nevertheless, even though the material is thin, compressing it and packing it to the small sack might be a bit more difficult. It requires that all the air is pushed out of the mat and no one likes this activity. However, the comfort during the night is making up to the lack of insulation, at least in spring time.


Even though the temperature rating is not mentioned in the manufacturer’s specifications, this is spring and summer sleeping mat. Even though its comfortableness is indisputable, this is not an insulated pad for cold weather conditions. If you are looking for such item, look through our other pad reviews. Its R value is 0,7 which makes it less of an insulator between you and the cold ground and more of a supportive pad that will keep you comfortable throughout the night.


The comfort of the Sea to summit sleeping mat is greatly connected to the intensity of inflation that you choose to do. The inflation and deflation process is usually the main issue with the air mats, which greatly affects the comfort level. However, the Sea to Summit inflation system is easy to use and quite effective and, most importantly, it stays the same for the entire night. This ensures that you start with a certain comfort of your choice and wake up with the same one in the morning.

For this reason, they are pending their patent approval, which would make them the only company using such inflation system. The mat contains low profile valves and this is the main reason why the inflation and deflation are occurring faster than with any competitive model. There is also a possibility of tuning your comfort level, which means that you could sleep on a harder surface by inflating it more or a softer one with only 30 seconds of inflation.

In order to do so, this mat is equipped with the Sea to Summit pump which is completely electronic free, even though it is as effective as an electronic pump. The inflation process wouldn’t require you more than 1 minute even if you intend on inflating it hard. It would only require 8 to 12 full breaths, so there is no risk of fainting while inflating it as it is the case in some competitive products. The deflation process, however, is even faster and it takes only few seconds.

Water resistance

This sleeping mat also comes with a high quality sack, which is made from nylon material. This makes the sack completely waterproof and breathable. It is important for the packaging sack to be breathable because if it gets wet for any reason, it will partly dry itself while you are transporting it.

However, this doesn’t mean that you shouldn’t dry it out before compressing it; drying it out on the sun is always necessary. A 3M kit for repairing the mat is also included in the package. The kit contains 6 patches, and one spare silicone valve insert which works one way.


The main issue with air pads, is their noise, when you are moving in the middle of the night. Unfortunately, Sea to Summit hasn’t solved this issue and it is a bit noisy if you are a restless sleeper. However, there are mats that are more noisy, so it is not too bad. If you are a tight sleeper though, this sleeping mat would be ideal for you.

Unique features

Ultralight: This sleeping mat’s main advantage compared to similar models on the market is its weight which is considerably lighter. It owes this feature to the thinness of the mat itself and its durable material. The material is durable enough so that it won’t get damaged easily, yet it is light enough so that you have a considerable lower amount of weight on your back during your trip to the nature.

Inflation and deflation: Sea to Summit have recognized their leading feature and failed a patent request for their inflation and deflation technology. With the help of multi function valves, the inflation and deflation process is very fast and effortless. As mentioned before, the process itself, doesn’t take more than a minute and only 8 to 12 mouth inflations depending on your preferences for the sleeping mat’s hardness.

Air sprung cells: The air sprung cells is a feature that is bringing this sleeping mat to the top between its competitor’s models. The cells have an involvement in the packed volume of the sleeping mat as well as its minimum weight properties. They also let it operate as a pocket sprung mattress which means that the support they are providing is incomparable with any other model on the market.

Value for Money & Guarantee

The Sea to Summit provides a great value for the price offered, at least if you use it as recommended. If you try using a sleeping mat such as this one on colder weather, or on rocky terrain you will of course be dissatisfied. However, when used right, you will definitely be amazed by the features and comfort it has to offer.
