80% Memory Foam, 20% Air — Adjustable Every Night The foam core gives you a consistent base while the air component lets you customize. Firmer for back sleepers, softer for side sleepers, somewhere in between for everyone else. No two people sleep the same way — this one accounts for that. Self-Inflates on Open Open the valve when you pop the tent and the foam begins expanding on its own. A quick top-up with a pump gets you to your preferred firmness from there. No manual inflation from scratch, no electric pump required — though an air pump makes the process faster. One owner notes: "all I have to do is open the vents when I open it and close them a minute after I opened the tent." 3" Thick Inflated, 0.5" Packed Three inches of sleeping thickness when inflated, half an inch when fully deflated and rolled. Leaves plenty of room in the tent for bedding on top without adding meaningful bulk when packed. Innovative Valve Design The inflate/deflate nozzles are designed to hold air during inflation and release cleanly during deflation — no backflow, no fighting the valve. One reviewer called them "genius."
