first one is the bomber cot made in America last forever, mine was purchased some where in mid 90's used a ton and still like new except for a few scratches on the legs. the roll a cot is the bomb on Grand Canyon trips as it gets you up off the sand away from a lot of the crawlie critters and on hot nights I sleep close to the water and some height for rising tides.
Second one is the quality cot I now use when camping in small tents
Made in Australia sold here by big agnes I believe
Several copies of the helinox on the market that my guess is will not last like the helinox units. my helinox cot and sunset chair go on a lot of canoe trips and light weight raft trips. The helinox is just as comfy as the camptime, just lower to the ground.
with all broken bones (healed but not in the line up originally as the Great Spirit intended) the camp time AKA roll a cot is much easier to get up from than the helinox. But the helinox works in a back packing tent.
