Sea to Summit Comfort Deluxe Self-Inflating Sleeping Pad review

Sea to Summit's Comfort Deluxe is a self-inflating mattress built for car camping, overlanding and van life rather than backpacking. Its ASTM-tested R-value of 7.7 is the highest of anything we compared, which means it holds warmth even on frozen ground, and its Air Frame construction pairs foam with air for a stable surface. A stretch-knit top conforms to the body, and the storage sack doubles as a high-volume Airstream HV pump sack, so you inflate it without power. The XPEL valve lets you adjust firmness quickly and dump air when packing. Sizes run from a Regular Rectangular Wide at 72 by 25 inches to a Double at 78 by 52 inches, all 4 inches thick. The Regular Wide cost $265.00 on Sea to Summit's US store when we checked, with free US shipping on orders over $50. It is expensive, heavy in Double size at 143.2 ounces, and sits on the ground, so it is a camping bed, not a guest bed.
