How long does the CloudSleeper stay inflated?

In normal circumstances, the CloudSleeper™ stays inflated for weeks and should not leak at all. However, as air expands with increasing temperature and contracts when cooled, you might experience some variation in firmness when, for example, moving the CloudSleeper™ from a hot to a cold area and vice versa. You can adjust the firmness at any time by giving it a few pushes on the pump area or releasing some air.
