We keep wanting to try the suites at ASMu but always back out because we're afraid DS will not be comfortable sleeping on one of the pullouts. He's a big guy - not just tall, but heavy also. He usually sleeps curled on his side so I'm not so much worried about the bed not being long enough. I'm afraid the mattress won't be thick enough and he'll feel bars or parts of the frame and be uncomfortable. Anyone had a larger family member sleep on one of these and can comment on how comfy they were? We were also wondering if it would work to put something like a foam pad (the kind you use for camping maybe) between the mattress and frame. If memory serves, the design of the pullouts is unusual tho so would that even be possible?
