The ultimate in luxury for base campers, the Comfort Deluxe Self-Inflating Sleeping Mat features four inches of plush foam and a 30D stretch knit fabric on the upper surface for a luxurious warm feeling when it’s cool, and a cool feeling when it’s hot. The flip-over multi-function valve makes packing up the pad relatively easy because it prevents air from being drawn back in as it's rolled up.
Be aware - if you pull out a Comfort Deluxe for house guests, they may end up staying longer than originally planned!
To make inflation and deflation of its air mats easier, Sea to Summit developed the multi-function valve. This valve integrates an inflate port with a one-way valve to prevent air loss before you seal the valve, a rapid air dump deflate port, and a fine tune button to adjust for comfort - all in one compact, low profile unit. It has also been designed to allow easy attachment of a pump, for simpler inflation.
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.
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.

Frequently Asked questions
Is the Comfort Deluxe Self-Inflating Pad warm enough for winter conditions?
Absolutely. This self-inflating pad has a tested R-Value of 6.5 – perfect for cold-weather adventures.
Is this sleeping pad's packed size small enough for non-motorized travel?
No. The packed volume of the Comfort Deluxe Self-Inflating Sleeping Pad is similar to a folding camp chair, so most backpackers, hikers, and bikepackers pack something lighter and more compact.
Is the sleeping pad easy to pack into its stuff sack?
A larger sleeping pad will always require some effort to pack into its stuff sack. However, this pad features a flip-over valve which prevents the pad from drawing air back in while it's being rolled up, making it easier to deflate.
