This pad is like a number of other self inflating pads on the market in that it can quickly unfold to provide moderate sleeping support. However, this pad does not very quickly deflate and roll back up, and is not long enough to cover the entire body. Additionally, the small thickness of the padding available to you in this product affords you less than adequate comfort on hard surfaces such as concrete flooring. I would imagine it would be adequate as a yoga mat or in conjunction with another kind of mat or sleeping bag. I would recommend this product as something kind of to keep in the back of the truck, just in case you need something better than nothing to lay on. It's small rolled up size is ideal for this purpose. Anyone needing extended or more than occasional use would be better suited by a full fledged sleeping bag.
