For my bike ride on the lake, I needed a mattress. I chose the Trek Bed 2 and was surprised how comfortable it is. You sit on it, it is still quite skeptical because it pushes the air and just sitting on the floor. Once you lie down, the air is distributed so that it no longer lies on the floor but comfortable "floats". Class. Especially cold the weather was not, but not hot, so I can not say much thermal comfort, other than that it was ok. The Selbtaufpumpen goes afloat. So even afloat that one rolls up times better 2 or 3 the mattress to rauszukriegen all air, as they can fill up when rolling again.
It was a nice holiday with restful sleep. We recommend.
