The Comfort Plus Insulated Air Sleeping Mat earned a 2015 Backpacker Editors' Choice award for its innovative Air Sprung Cell technology and dual layer comfort. With two separate layers of interlocking air chambers and our multi-function valve, you can fine-tune the top layer to perfection as well as adjust the base layer to accommodate for rough terrain. So, if one side of the pad punctures, the other remains functional until a repair is made.
It's also insulated with Thermolite® and Exkin Platinum® for great warmth.

Air Sprung Cells™ are the core technology used in Sea to Summit Air Mats and are the reason you will sleep more comfortably on a Sea to Summit mat than on a conventional air pad. Inspired by the hundreds of springs found in a modern pocket sprung mattress, the hundreds of small interconnected chambers (called Air Sprung Cells™) perfectly support your weight and conform to your body contours. The Comfort Plus series of mats has an internal layer of 40 Denier Nylon dividing the mat into an upper and a lower chamber. This allows the welds of the lower and upper cells to be offset throughout the entire mat, resulting in the greatest possible support and insulation, and a unique ability to fine-tune comfort. When on uneven terrain the bottom layer of the mat can be inflated to a high pressure as a barrier. The upper layer can then be adjusted - using the fine tune valve – for more comfort and softness. This also ensures a level of built-in redundancy. If one layer becomes punctured, you can still get through the night with the other layer of the mattress intact. Dual layer construction air mats are perfect for those looking for the ultimate in comfort and insulation, who are prepared to carry a few more ounces
The Airstream Pumpsack is Sea to Summit's big volume mattress pump which we've now integrated into the stuff sack of every Air Sprung Cell mat. The clever design opens at one end to stow the air mat and the other end unfolds to become the built-in pump. The Airstream Pumpsack can be inflated with a single breath and takes just two or three cycles to fill our mats. Not only is it faster than inflation by mouth, but there is minimal breath condensation entering the mat and it eliminates dizziness from blowing the mat up directly by mouth. The Airstream Pumpsack is also compatible with Sea to Summit's smaller multifunction valve, which is now featured on the updated Aeros pillow range, along with the Air Seats.
To ensure that you will be warm when you sleep (especially when the ground is colder), it is essential to know how well your sleeping mat resists heat loss into the ground. This resistance is known as an R-Value. A laboratory-tested R-Value is the only way to measure resistance to heat loss. Sea to Summit has always provided independent lab-tested R-Values for its sleeping mats. Since January 2020 we have used the industry standard ASTM F3340-18 test to provide R-Values for our mats. There are other factors which will determine how well a sleeping mat will insulate; but the standardized ASTM R-Value test means that you can compare resistance to heat loss in sleeping pads across different brands.
Thermolite® HL-1 is part of the family of Thermolite® materials used in Sea to Summit sleeping bags, sleeping bag liners and sleeping mats. HL-1 high loft insulation is a fiberfill constructed with a unique 3D crimp of hollow-core and solid fibers, which provides excellent lightweight warmth with superior durability. The Thermolite insulation lofts up inside the Air Sprung Cells™ of our sleeping mats to prevent convective heat loss from your warm body to the cold ground.
Frequently Asked questions
Really comfortable at this thickness?
Yes. Thickness isn't the key factor for sleeping pad comfort – the number of points of suspension is. Our air sprung cell sleeping pads support your body weight with hundreds of individually air-filled springs.
Easy to inflate?
Yes! The supplied stuff sack features an integrated Airstream Pump which will quickly inflate the sleeping pad. This means no dizziness for you, and practically no condensation moisture inside the pad.
Is the Comfort Plus Insulated warm enough for four-season use?
Yes. This air sleeping pad has a tested R-Value of 4 which is enough insulation for all but the coldest ground.
Suitable for backpacking when a little over 1.5lbs?
Possibly. At a little over one and a half pounds this sleeping pad is a little heavy for warm weather backpacking, but fine for backpacking in cold-environments.
