I got the bed for a trip we are planning, but when my little 3 yr old saw it, he just had to jump in it and would not come out. He has been sleeping in it every night for a week now (As he prefers it to his regular bed), and we still did not have to re-inflate! He loves the fact that the blanket is open from the top as he does not like to feel "trapped" Plus, it is small and light enough to take on one of those cheaper airlines with lots of restrictions. Another plus is the great hand pump which is not electric which means I can take it wherever without an adapter. The zipper is a safety Zip so kids can't open or play around with it. I use one of my hair pins. I have another item which uses this Zip, and the trick it to not force the zipper, just make sure you pull it at the right angle. We all love the bed, and I am now going to buy two more to give as gifts!
