Rated 4 out of 5 by from NO MORE AIR MATRESS! I purchased this for a camping trip a few years back, but then forgot I had it for a while. After rediscover it I can't stop finding great uses for it! At 3in it is super comfortable when camping, but I also always have them handy around the house for when guests come and need a comfortable place to crash for the night. Although it is too large to use for backpacking (this has not stopped me for using it while in a pinch though!), it is still a great solution for all of your car camping needs. As someone who works in the outdoor retail community, I would highly recommend Therm-A-Rest for the perfect nights sleep.

Rated 5 out of 5 by from Durable and comfortable - a good investment I have used my Basecamp mattress regularly for the last 7 years. It has been trouble free, and is still in great condition with little to no wear to show for it. I would expect it to last for another 7 at this rate! In addition to this it has been effective and comfortable in year round conditions. At 6', 200 lbs, with a width of 24" the XL gives me plenty of room and support. I even bought the fitted sheet and tech blanket to go with my Basecamp, which works great as well!

Rated 5 out of 5 by from Super comfortable I gave my old (well used and fantastic) thermarest mattress to a friend in need (his budget mattress had collapsed!) and decided to treat myself to a Basecamp mattress as I mostly take my car when I go camping these days. So glad I did because this mattress is super comfortable (like my old thermarest was) but has just that bit of extra thickness that means that it helps keep me nice and warm from the cold ground when I'm winter camping. It's perfect cosy comfort means I get a great nights sleep whatever the ground conditions or weather conditions. Would 100% recommend this mattress as long as weight isn't an issue for you.

Rated 5 out of 5 by from Not the workhorse, but the Clydesdale of camp mats These luxuriant mats turn cots, bunks, and even cold hard ground into comfortable sleeping platforms. Almost impervious to wear, tear, and punctures, easily repaired if you're careless, and with a bullet-proof warranty (Cascade Designs insisted on replacing a 30 yr. old pad, which by then owed me nothing...) Good gear, good company!

Rated 5 out of 5 by from Best sleep I ever had One of the best sleep experiences I've ever had camping and wondered why I never got one since. I've been camping without a sleeping pad for years and that had to stop with sleeplessness nights and aching hips and shoulders on days on trips. I'm so happy that I got Therm-a-rest base camp pad after much reviews and considerations. Get it! You will not be disappointed by the quality. First time buyer and loyal for life. Great for those that are looking for a great base camp sleeping pad, while weight and size is moderate and could be used for backpacking, but may consider something smaller lighter in Therm-a-rests line.

Rated 5 out of 5 by from It's my bed... seriously! Somewhere in 2014 I bought a used gymnastics mat and made it into my bed. I was in pain after a few day. Even with two inches of foam, I could not handle sleeping on the floor. Desperate to sleep in comfort I dug out my basecamp XL and added it to my bedding. I remember laying on it and thinking, "Oh my god. This feels so good." In late 2015 when I decided I was going to hit the road in a van. I knew what I was going to use as a bed. Utilizing the tumbling mat and some plywood I made a bed big enough for my 6'7" frame and another person (just in case). I bought another basecamp mattress and lay them side by side when I want have the equivalent to a queen size bed in the back. It's perfect!

Rated 4 out of 5 by from Getting old and need comfort. At 62 and after 2 back surgeries, sleeping in a tent can be a tad challenging. My thermorest makes it so I can still move in the morning. It provides good insulation from the cold and softens that hard ground enough for me to sleep quite well. I have a 2" model and am looking at a thicker one considering my old body.

Rated 4 out of 5 by from Durable & Lightweight I bought this to take on our scout trek at Philmont Scout Ranch in New Mexico. It has gone through a lot of extreme conditions, yet day in and day out it never failed. We packed up every day and hiked to our next site and set up camp. It was able to provide me with many nights of rest for my sore muscles.
