Camping luxury has a new look and feel with the Comfort Plus™ Self Inflating Sleeping Mat. This is a lush, 3-inch thick, light and easy to use option for anyone after maximum comfort. The Delta Core™ technology removes weight and bulk without compromising comfort. A lightweight but luxurious 30D stretch knit fabric is used on the top surface and each mat is embossed with a non-slip grip print to keep your sleeping bag on the sleeping mat. We've literally put a twist on our multi-function valve to ensure super-fast deflation without fighting re-inflation as you roll it up.
Our blog post "Which Mat Should I Choose" has some helpful tips on picking the perfect self-inflating mat (or reasons why you might prefer an air mat).
Is the Comfort Plus Self-Inflating Sleeping Mat...?
- Insulated well enough for three-season temperatures? Yes. The Comfort Plus SI Mat has a tested R-Value of 4.1 – suitable for anything but really cold ground.
- Small enough when packed to use for backpacking? Possibly. If you are only hiking for a short distance, the weight (34ozs) and packed size (7” x 10”) – both size Regular – could work. For longer trips an air mat would be a better option– see below.
- Easy to pack up? Relatively easy. The flip-over valve prevents the mat from drawing air back in while it is being rolled up – but the larger sizes (including the Double) still require a little effort to pack into their stuff sacks.

Technical Features
Delta Core™
The innovative Delta Core™ system maximizes the comfort and thickness of our Self Inflating mattresses while minimizing weight and bulk. 40% of the initial volume of the PU foam is removed in horizontal Delta-shaped cores, giving minimal weight and packed size. Importantly, the top and bottom surface of the PU foam remain completely intact. This ensures consistent warmth along the full length of the mattress and significantly improves bonding of the foam to the shell fabric, which reduces the chance of delamination.
The shape and size of the Delta Cores™ are adjusted across the different thicknesses of our mattresses to ensure strength and durability combined with excellent support. The horizontal Delta Core™ technique is used in our Comfort Light SI, Comfort Plus SI, and Comfort Deluxe SI models.
SI Multi-Function Valve
We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats - that is, the problem of the foam trying to re-inflate as you're packing up. We've engineered the "one-way" inflation valve to be reversed and used to prevent the mat from drawing air back in. This allows you to roll the mat up as small as possible without fighting re-inflation as you go. This patent-pending valve design has the same slim profile, faster inflation than traditional screw valves, easy pressure fine tuning, and super fast deflation rate as our air mattresses and pillows.
Pillow Lock™ System
The Pillow Lock™ System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019),
Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics.
All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock™ compatible by adding an Aeros Pillow Case.

Make sure the mat is thoroughly dry before storing it (and store it with the valve open laid flat if possible)
