Q: These are only meant for use as temporary or guest bedding, but I've been in a situation where I am using this item daily as my bed for over a month now. I am a large person. It has held up beautifully. I add air maybe once every 7-10 days. The flocked top is great, holding sheets in place. It is so comfortable, my back and general body pain has improved dramatically since using it! I suspect that when my permanent bed arrives, this little bed will serve long and well as guest bedding.

A: Positive
****
Q: A classic story based on history. One of Hypatia's crimes appears to have been ready to provide a hypothesis of a heliocentric universe, long before Copernicus and with a much worse response from the Christian community.

A: Positive

Imagine my surprize at having it deflate within an hour of getting is set up in my room. I ended up sleeping on the floor that night.We'll see how the return process goes. I'm headed out to buy an air mattress locally.

Negative
