I just have to say the "off gassing" mentioned in the single bad review you see here is something that lasts about 24 hours. I'm asthmatic and have allergies and would be the first to say if a smell or chemical were a problem. In fact this mattress is the most amazing comfortable thing EVER and the slight smell that comes with the initial opening of the package is gone forever after the first 1-3 days. By the way I have bought this same thing 3 times for myself and then Queens for my 2 children.

We are in our 50's with neck & back problems, and both of us felt like we were lying on a cloud in heaven! This is the best and one mattress you would have to buy and under 300.00! If you are looking for a Mattress...STOP...it's right here...buy this one it's AMAZING!!! I would NEVER buy anything else 5 stars doesn't give a high enough rating they deserve a whole lot more stars********************************** Night therapy foam memory is the way to go. No odor and it didn't take 3 days to inflate either.

For the money this memory foam mattress is great. After the initial set up time went by and the foam had reached its full expansion it was time to test it out. Very comfortable and not to soft or hard just the right amount of give without struggling to turn over during the night. No unpleasant odor like some memory foam mattresses have. I bought this due to the high ratings and the reasonable price and I am glad I did. If you are looking for a memory foam mattress this may be the one you have been looking for.

This is my THIRD night therapy memory foam mattress i've purchased from Sams.....I lOVE THEM and they are a great price. you can replace every 4, 5 years at this price and not feel bad about spending your dollars on these mattresses vs. 3500+ for the name brand ones. I love them.

My son needed a new mattress. I searched online and in many stores for affordable options. Some did come in slightly lower than this mattress, but they were half as thick, or not memory foam at all. I wanted him to have a nice memory foam mattress that could last through middle school and high school. NOTHING this nice was offered at this price anywhere else. When it arrived, I let it expand on the living room floor. My husband asked how it felt, so I went to try it in order to report to him at work if it was worth the purchase. I have trouble sleeping. He arrived home to me passed out for four hours in the living room on this twin mattress. No smell from the foam, expanded within 5 minutes, best mattress I had ever slept on till the 12" version of this came the next day for our bed. This mattress is not as extremely firm as the 12" pressure relief version we chose, which makes it perfect for our 11-year-old son. I would recommend this mattress to anyone who would not like the firmer option but dislikes the sinking into a pile of squish that the softer mattresses offer. It is a nice Goldilocks balance.

I think it is a good quality mattress and I like the zip off mattress cover so it can be washed. I bought it for my Saint Bernard to sleep on. Large dog beds can cost well over $100.00 and they are usually made from egg crate foam which is not much cushion for a 160 lb dog. It is also much easier to change a fitted sheet then it is to take a cover off of a dog bed. I think it is a good mattress for dogs or people. I have not slept on the mattress but I have sat on it and it is a firm mattress.

I am currently working on the road and the mattress that was in my 5th wheel was shot. This mattress is working perfect as a replacement and I didn't have to spend a bunch of money to get it. Plus, the way it was packaged made it very easy to put in place. Very comfortable.

We purchased these for our two teenage boys and they are amazing! Anyone considering purchasing this mattress should! I was leery at first because the price seemed to good to believe but when they got here I was so pleased! This was absolutely one of the best purchases I have ever made from Sams!

Arrived ahead of the estimated delivery date. Because it arrives rolled up it was simple to install in the RV. Had almost no odor and inflated quickly. Checked on it the next day and it was up to 7 3/4 inches high. Could not detect any odor the 3rd day it was in the RV. Have not had a chance to sleep on it overnight, but it felt very comfortable laying on it for about 1/2 hour.
