I was looking for an alternative to my 3cm thin light-Isoma because I had no desire for aching hips. First things first: the mattress is much smaller than indicated! The real dimensions are inflated 180 x 50cm with 6cm thick. The weight is 800g- as light as my Therm-a-Rest. The pack size is 20cm x D 10cm L. If you inflate the mattress not too hard (which is not too difficult, incidentally, you have to stop during inflation with the teeth, the check valve compress), then it is quite convenient (at 1.80m height and moderate fighting weight :-). When the outer chambers inflates tighter than the inside, is also reduces the risk of rolling down. I just slept times on the floor in the living room with it and it was - compared with similar light and small Isomas- very convenient. Burst seams etc. I could not even notice. The mattress was so flat after 2 days that I had-but inflate something back is important to me only that I can sleep through the night with it. The only drawback: let out the air, you have in each of the 6 valves a small, enclosed "straw" stuck to open the non-return valves. That's inconvenient and when one is away from those things, rolling up is quite cumbersome. If the seams now continue to hold, then the part of the price is highly recommended.
