    In 1971, a mix of unemployed Boeing engineers, a leaky foam gardening pad, and the dream of better nights under the stars came together to change how we experience the outdoors forever.

    By 1972, Cascade Designs was formed and began selling the Therm-a-Rest Standard 3/4 – the world’s first self-inflating sleeping pad.

    The rest, as they say, is history.

Be careful with "like new" headline

Be careful with "like new" headline
I knew this was an 'open box' return when I purchased it. However, the headline said 'like new' so I figured I would give it a try. Unfortunately, the cot was severely damaged by the previous owner, and no one at Amazon checked the contents. This cot has 10 plastic feet. Two feet were completely broken (see picture) while one had a serious crack in it and will break upon first use. Amazon should have caught the broken feet and not resold this returned item.Regarding the cot itself, I assume the first owner could not figure out how to assemble it, hence the broken feet. It's not that hard to figure out how to assemble if you follow the instructions and have reasonable strength. But I will say it is definitely NOT EASY TO ASSEMBLE.The full cot including carry case measured out to exactly 2.9 pounds. It is backpacking possible, but still heavy to carry on the trail. But on the other hand, this is the lightest cot on the market and this needs to be acknowledged.I have a sore back and was willing to carry a cot during an upcoming trek, if the cost (weight) was worth the benefit (alleviate the sore back). Unfortunately, I don't think the trade off is worth it. Three pounds of cot alone is not comfortable enough, and if I need to add a lightweight inflatable pad on top of the cot I am approaching 4 pounds of weight which is too much. Ultimately, I decided on my Klymit inflatable pad, and a memory foam pad for my lower back support. This is just under 2 pounds total weight for the two, and seems to give me the relief I need.Regarding long-term durability, I have to question whether this cot is strong enough for rough use in the field. If I paid full price and I found the the feet break this easy, I wouldn't expect this to have long-term durability unless you really baby it in the field. You better plant yourself very carefully on the cot.

I thought this cot would be great when I received it….I was wrong. For reference I am 5’10 180lbs. First trip was an overnight and the plastic foot broke and bent the aluminum pole I Ordered a replacement kit for it when I got home….LAME! Second trip I made sure the ground was ultra flat which is near impossible when backpacking I slept on it two nights no issues. Third trip was a 5 night backpacking trip in hells canyon. I Made an ultra smooth spot which really sucked to do in that rocky country first two night were fine third night the stitching started to rip and continued to rip the rest of the trip ended up sleeping with my arm through the hole in the fabric…REALLY LAME! I reached out to customer service and they said they will replace it whenever it is back in stock…when no idea. Asked for a refund they don’t offer refunds or credits. This cot is not meant for backpacking. DO NOT BUY THIS COT! I just bought the helinox convertible one and couldn’t be happier. What a difference in construction spend the extra money and get the helinox it’s worth it.

1.0 out of 5 stars Too Fragile - Crossbars Bend and Fabric Tears
Reviewed in the United States on January 6, 2022
Style: Regular - 24 X 72 InchesVerified Purchase
I really wanted to like this cot because I find it much more comfortable than a sleeping pad. However, after only about ten nights of use, the crossbars now retain slight bends and there is a small tear in the fabric at a seam. I found the Large to be barely adequate for my 5'11" frame (a few more inches would be nice), and at 210lb I do not touch the crossbars when I sleep (although my midsection is within a fraction of an inch of them with all of the legs and double crossbars in the middle). I treat it very delicately and always gently lower my weight mid-cot, never resting on the edges. However, on a recent trip, I sat up and put some weight near the seam, and the fabric immediately tore for several inches right along the stitching. Other reviews show images of very similar tears. While I am definitely not petite, I'm more than 100lbs below the maximum load of 325 lb 3 oz. (3 oz.?!!!).

Pros:
- Very lightweight and compact
- Setup and breakdown is reasonably straightforward (as with most things, it gets easier with practice and I highly recommend a few iterations at home)
- Surprisingly comfortable for a back sleeper (while I also sleep on my side, I don't find side sleeping to be comfortable on this cot)
- Sleeping above the ground is drier and cleaner. I hadn't considered this until I was caught in 36 hours of relentless rain while camping. My rainfly failed and my tent floor was soaked, but I was comfortably above the water. Those two dry nights may have justified the price of the cot!

Cons:
- Overly fragile. Mine broke even though I treated it gingerly, so I can't imagine it would survive someone heavier or with kids around
- Hard to imagine this would be comfortable for someone much heavier than me (210lbs), which is well below the max load (325lbs 3 oz)
- The legs may tear through tent floors, particularly if there are rocks below the tent. While they sell small 'coasters' for the legs, they are expensive and carrying 12 of them seems egregious

Bottom-line: buyer beware, as this cot may leave you without a place to sleep if it tears mid-trip.

4.0 out of 5 stars A good product that you have to dial in a bit for good results
Reviewed in the United States on November 14, 2019
Style: Regular - 24 X 72 InchesVerified Purchase
This is a pretty well made product that packs very thin and light, and that does the job well if you take some time to dial in how you set up the supports to meet your needs and preferences. It took me about four tries to find the arrangement that I liked and then it was great. Basically, there are multiple locations underneath the cot to attach the legs, and you can set the legs in two different ways to change how much tension they apply to the cot, so you can effectively make one part of the cot firmer or softer by changing around the configuration. The manual shows you two setups, one that it says is good for up to 175 lbs, and one for more or less maximum load. I tried the maximum load setup first despite being a bit under 175lbs and it made the cot far too stiff. Then I tried the lightweight setup and found that when I rolled to my side I would sometimes touch the ground with the side of my hips. I rearranged the support locations a bit so that there were two light supports at hip level, one under torso, one under head, one under feet, and have been happy with it since. If you're shorter or heavier in one area or another, you need to take a few minutes to adjust accordingly.

I used this in the high desert and on mountains over 8000 feet, in temperatures below 20F and it did its job well.

5.0 out of 5 stars Great backpacking cot!
Reviewed in the United States on April 18, 2022
Style: Large - 26 X 77 InchesVerified Purchase
I got this about a month ago to try out in place of my Xlite for warmer temp trips when my pack is lighter (not carrying winter gear) and I can afford a little extra weight penalty. I'm small at ⁵'5" and only 118lbs. I can get by with only using 3 cross bows making the cot sub 2lbs. It's very comfee, keeps me off the ground and I slept great on it on a 3 day AT trip in North Ga. The only thing I used with it was a 1/8 closed cell pad and my Alphalite 900 quilt. It's easy to assemble, very light for what it is and the comfort it offers. It packed down super small only using 3 cross bows and fit in the side pocket of my pack. Highly recommend, especially for smaller people. I might even take just the material for a tent rug in the winter to offer more insulation from the ground and also if I bring my dog to protect the inside of my tent floor. It's very durable as well. I love it!! ❤

5.0 out of 5 stars IF YOU HAVE TIME TO PACK/UNPACK...
Reviewed in the United Kingdom on January 5, 2021
Style: Regular - 24 X 72 InchesVerified Purchase
If you are someone that just has to be packed up or ready to get into your sleeping bag in an instant, then this cot is definitely not for you! As strong as it is, you do need to take your time and take care when constructing this (and deconstructing it). Personally I would hate causing any damage, to any single part of this cot - given how expensive it is! Watch the videos showing it being erected and you'll get an idea of how it goes together. It takes me around 7 to 8 minutes to put up.

It is (I would say, as I am NOT prepared to try) not suitable to sit on! Although I don't think it would actually break if you did sit on it, I don't want to take the risk that that much weight - focused in one point - wouldn't cause the material to stretch, and make a permanant crater where your bum cheeks applied that much pressure! I'm even so anal about this, that when I get onto or off the cot, I pretty much lay down alongside it and roll onto it - as evenly as possible, to distribute my weight (90Kgs) along the cot as much as I can!

That said, it's certainly not flimsy, and when you're on it, it is very comfortable. I use a quality inflatable mattress on top as well. I bought the cot always intending to use it with a mattress. Combined, they make a bed so comfy, that if we had guests staying over, I would look forward to using this option to free up my house bed!!! :-)
