When I first used this cot it seemed excellent. The frame is very sturdy and the cot was comfortable. If I had written a review at that point I would have given it 5 stars. But the second trip I took the cover burst like a balloon. Really, I could feel it give a little, and by the time I could get off it there was a 4 foot long rip. It was then I started looking closely at the material of the cover - it is some rubberized material with a few threads in it - not a real canvas. And it has zero rip-stop capability. I tried to sew it but it was like trying to sew a balloon - it just doesn't work. The Slumberjack people say they will give me a new cover, but they never seem to have one in stock to send (for 4 months?). Only get this cot if you plan on using it once! My previous cot lasted 8 years.
