Man’s best friend

a year ago
For any father that has experienced the dad couch/chair in the hospital this mattress is the bees knees and the ducks guts. It turns what I can only explain as an attempt to put the father in as much pain and agony as his wife into a soft delicate cloud bed. This fit perfectly on the dad chair and was complimented by all. Additionally this mattress has performed extremely well camping. Fathers to be this is a neccesity.

How to keep this short... I'm 72. Started back-pack camping in 1966. There were no back-pack camping mattresses, and if there were camping pads, I never saw one. In the early eighty's, as a"die hard" San Francisco bicyclist-skateboarder (Three spinal surgeries: w/ metal rod in 1976, then broke the rod and replaced it with a hip bone graft in 1986) I became passionate about snowboarding. Simply put: I discovered Thermarest sleeping pads and was able to go anywhere someone would let me lie down for the night, and get a good night's rest, then get up and go snowboarding. As a result, I became well employed in the industry. Now, I live on a boat, where I sleep on the Thermarest Mondo King over the standard foam mattress. (The bedside lockers won't open if blocked by a thicker mattress.) So, 40 years with Thermarest. Great memories, and a good back... HAPPY CUSTOMER!

Have had for 3 years, best sleeping pad I’ve ever owned. Durable. Comfortable. Easy to set up.

Changed design disappointing.

a year ago
I gave this bag a full five-star review. I used it for many years, and it just needed replaced. So I bought another one. Previous design had a smooth surface. New design has ridges on the surface, and I can feel them, so I need a pad for the pad. Doesn’t make sense. Why the change? It wasn’t for loyal users. Poor redesign. I am disappointed with the change from a wonderful pad to new design.

Camp and comfort

I have owned this pad for 5 years or so. Use it at least 2 times a year and just this year took it out on a ruck into the woods on a -15°F overnight. Honestly I'm incredibly impressed. I'm 6'2" 200lbs and I have spondylothesis of my L1 among other issues in my spine that cause me to toss and turn quit a bit. This pad delivers the support you need and the space for me to adjust my body without sliding off. While sleeping in the cold I never once noticed any coldness from my pad. With it in the bag and strapped to my pack, this pad made it through the brush and thicket. Although my bag did suffer a hole here or there, probably due to thorns, my pad was in touched. I couldnt be happier with my purchase as I am using it now while I type this in replacement of my current bed until my new mattress is delivered.

This thing is awesome. Luxurious sleeping on the ground. There’s no Basecamp mattress comparable.

Deluxe Car Camper

2 years ago
Purchased this pad for sleeping in the bed of my truck. It’s heavy and durable enough to get thrown in with a bunch of other equipment. It doesn’t pack down particularly small, but easily small enough for the trunk of a car or back of an extra cab truck. The storage bag which also doubles as an inflation sack is a really great feature; just let it self-inflate and then add 3-4 sacks of air and it’s ready to go. The surface of the pad has a soft chamois feel to it, not like a sticky backpacking pad. Overall, great product for car camping if you have the space to bring it along.

Big, soft, comfy!

This is the King of air mats! Though it's primary use is car camping (in luxury!), I make space for this beast on rafting trips. It's remarkably lightweight for its size. The adjustability on firmness is pretty amazing as well.
