Teton Outfitter Sleeping Pad for Cot, Extra Thick Comfortable Camping Mattress for Adults, Portable Roll-Up Camp Pad, Durable Foam Cushioning

It's not as thick but Teton has a 3" air/foam pad that we use in our RTT. It's been comfortable, the wife and kids have no complaints, it's easy to inflate and deflate. And it comes with a lifetime warranty. This was the big reason I bought it, I've had a few air mattresses fail me, including a $150+ exped knock off Teton Sequoia mattress
