[Q]: I ordered 3 of these. They are sturdy, comfortable, and stay inflated. The electric motor in each easily and quickly inflates and (almost) deflates them. The height also makes them feel more like a real bed.However, if you want to completely deflate them for storage, that can be a real trick. I could never deflate any of them completely, so in frustration I cut one open to see what the problem is. A design flaw allows an internal plastic flap to cover the deflation port when they are almost empty. The more you try to vacuum or squeeze out air, the tighter the flap seals the port, sealing in the last bit of air.Now I know, and there's nothing I can do about it, but I feel better after attacking one with scissors...
[A]: Negative

[Q]: I too was ready to buy this product, but will not do it if I can't get the color I choose. I guess this company doesn't want to put their customers first!
[A]: Negative

[Q]: No, I'm not talking about Hester's crime. I'm talking about this STUPID BOOK! If only Hawthorne had kept his job in the customs house (see prologue), this abomination would never have been spawned from the cess-ridden depths of Hawthorne's twisted thinking organ. (You can figure THAT out on your own). This book is untolerably boring (the only proven cure of insomnia - if you don't mind the side effects) and the descriptions are ridiculously entangling. In the words of Mr. Hawthorne himself, this book is "ignominiously" dull. PRESERVE YOUR SANITY! NEVER READ THIS! NEVER!I sleep now...
