Input: Consider Input: 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.

Output: Positive

Input: Consider Input: Ordered two and tested them out: one had a bad pump but the return was easy.These airbeds are super cheap and great. Everyone who has slept on them says they are extremely comfortable. They hold the air well. I recommend them very highly
