Get a Roll-A-Cot. THEY ARE MADE OF ALUMINUM. No wood is used in the construction of a roll-a-cot. I have 3 and they don’t rot or rust. I recommend the mesh version over the cordura version with the pocket for your sleeping pad. Sand falls through the mesh, mesh dries quickly when wet, and the pocket is a useless gimmick.
I used to be dead set against cots. But thanks to the Buzz I saw the light about cots. The big reason for the change of heart is cots allow you to sleep in places you can’t with a sleeping pad. On rivers, it seems like there are limited flat spots to set up a tent and sleeping pad. I have slept without a tent or under my tarp many times on rocky ground, or sloping ground thanks to my cot. On rocks, the cot puts you above them. On a slope, by putting 2 rocks under the downhill legs, you can level the cot. The key to all of this is a cot with 4 contact points to the ground. More than 4 and the chore of leveling the cot with rocks under the legs on a slope or rocky ground becomes quite tedious.
One of the other big benefits of cots is shoving your stuff underneath them and out of the way. Once again the roll-a-cot is ideal because it only has 2 leg assemblies and is tall, making it easy to store gear underneath it.
I don’t know what your intended use is. You posted on a rafting board, so I’m assuming you’re planning on using them for rivers. A lot of of the cots I’ve seen listed above are going to be great for car camping. Some are better than others, but none are as good as the roll-a-cot. Many are too low to the ground. All of the ones I saw listed had 6 or more contact points to the ground. There is a reason everyone on here has the Roll-a-Cot.
Cots and backpacking tents don’t mix. Just sleep on your pad. If you’re backpacking and carrying a cot, ditch it. Your back and shoulders will thank you. If you’re car camping, get a big tent that fits your cot. Or a dragonfly tarp like the one in my pic.
In the attached pics I’ve got the cots set up on rocky ground. On the pic with the tarp, we are camping on a pretty good slope. I put some flat rocks under the down hill legs of the cot.
