This mat; whilst it may seem a little more expensive is very very comfortable and insulating from the ground. It packs up very small which is helpful for backpackers like me. After you first buy it and unpack it, you will need to top it up repeatedly to get the foam to max out, but after that, the mattress is good to go.
