Sturdy and easily inflated with manual foot pump, I used Intex bellows foot pump - would take too much air to blow up yourself unless you are much younger than I am. Used it to sleep on for 3 weeks daily and it saved my back. Put a quilt or blanket over it for comfort, needs something on the plastic or I don't think it would be too comfortable to sleep on. Not really backpack practical but if you are car or backyard camping should be fine. Did the job and is reasonably priced.
