Yes I leave them in place on the on top of the Penthouse Bed with the valve open , Penthouse comes down and the air coms out , Penthouse goes up and at least half of the air return's , just a couple or three good puff's , Twist the valve lock and you are good to go . My wife hurt her back last year and being able to adjust these mat's has made a big difference to her comfort level's , some night's are more difficult than other's . Here favorite is the Cabelas Alaskan (Lge) as she say's that it allows for a more adjustment . We also use outside when we Backpack and Snow Camp , I would have loved to have them forty plus year's ago to replace the Pine needles and Grass mattress that I had to use. They Prick and Leak !
