I have had my eye on one of these for a while. . . .
Picked up a Thermarest Chinese knock off on amazon. I know, I know!
Yahill Ultralight Folding Bed Portable Cot, amazon deal under $50, How could I resist? Looks exactly like the thermarest from what I gather. seems to be a few others for under $100.
I just received it this week, weighed it, 3.6# all together on my baby scale. Set it up, easy enough. Laid on it and almost fell asleep in the room. This is nice! I did notice the sag with all supports assembled,(I had double rods at each end) on my stomach the lowest part on me was about 1-1.5 inches off the ground. my Specs: 175# and short as sh*t. Might have to play with rod placement.
I can see myself really liking this, I toss, turn, side sleep and stomach sleep. I often wake up paralyzed from sleeping on my limbs. 3.6# kinda of has me asking myself where this fits and when/where would I take it? What would my sleep system be?
I find it very interesting to hear Justin's feed back about not freezing with the lack of insulation on the bottom. I was almost certain that I would need my pad still or I thought about my thermarest z-lite(which is not the most compress-able piece).
Full disclosure: I have no field use with this product. Never left the carpet, I played with it for 5 minutes then had to pack it up and set it aside to be wrapped and placed under the tree so I can be surprised at Christmas. which will probably happen as I will forget about it by then. Gear whore problems.
