Thickness is king when it comes to inflatable mattresses. I was able to sleep comfortably and not wake up saw. I also reduced the weight of my previous mattresses. This mattress is 540g. Surface was a little slippery but no different from any other mattress I have tried. The valve system was excellent, in that it was simple and did not leak. I would have liked a method to adjust the pressure while lying on the mattress (but no one else has that either).
