A cheap way to make a few cots for this would be.
yoga mats or self inflating camping mats then cut 1/2 inch plywood to the same size as the mats. If you wish you could also cut out handle holes at the same time in case you need to move the person. Place the board on four bricks or buckets to give it height.
