This mattress only raised up 6" not 8" as listed on the title. Its comfortable but not as thick as i wanted.

I love this bed. Previously had a $1600.00 traditional mattress king bed, followed by a spring mattress with foam. No sleep. After less than a year on the last bed, we purchased these 2 twin xl 8" memory foam mattresses and placed them on the king size box springs we already had. This bed sleeps great. I have neck, back and arthritis problems. I have already slept better on this bed in one week than all year on either previous bed!!!

I was a little worried about this purchase because I was purchasing it for a daybed whose dimensions were half an inch narrower and half an inch shorter than the dimensions of this mattress. I called the manufacturer and they told me that the mattress has a bit of give in the foam and that it would work. It worked perfectly. It took this mattress about three days to reach full height. I also bought the regular size mattress for the trundle, and that one seemed to expand to full size in about a day, so I'm not sure why this one was different. Maybe it's compacted more--it's bigger yet arrives in the same size box as the regular twin. Anyway, the mattress is super comfortable. Oh, I also asked the manufacturer if it has to sit on a solid surface (like a full board) because my daybed has slats. They told me the slats would be enough support--my bed has 15 slats with a couple inches between each one. The odor from the bed is pretty strong but not horribly unpleasant. It took about 4 days to dissipate to the point where I wanted to put sheets on it. My teenaged daughter has slept on it a couple of nights and says it's comfy.

If you are not allergic to this type mattress then it is an excellent buy. Not long before ordering this, I bought a Carswell Serta mattress from Sams. It is wonderful! I wanted to try the Foam for a twin in our spare bedroom so ordered this one. All was well until we couldnt get the smell out of it and laying on it I found that I got headaches and felt bad. Had to return it and luckily Sams had just added a Twin Carswell, YAY! Returned the foam to our Club for a No Hassle refund and the Great Carswell is on the way. Love dealing with Sams, wont buy foam again though.

I purchased this bed hoping that I would get some lower back relief from my previous hard mattress. While it was softer it only lasted for about 6 months before I just started to sink like a rock and there was a permanent dead spot right where I normally slept. Currently going to contact samsclub for a refund because I don't want another.

I am looking for a decently priced firm yet supportive mattress so I purchased the 8" Night Therapy memory foam mattress from sams. The mattress arrived in several days and I opened it and let it 'inflate'. I slept on it and the off gassing was so severe that I coughed for two days, my sinuses were congested and felt really sick. The odor filled the entire first floor of my house. If you are in any way sensitive to odors DO NOT BUY this mattress. Perhaps if they let this mattress off gas for a year then maybe, MAYBE I could sleep on it. wow. Thanks for Sams return policy I returned it and purchased an innerspring mattress at the local club.

We bought TWO (2) of these beds to replace our 13 and 15 year old daughters' worn out spring mattresses. Of course, when they 1st laid down on the bed, they said it was too stiff. However, after a few night of quality sleep - they are NOT complaining. In fact, they said they liked their new beds... So for the parents of these girls, we give these beds a 5 STAR rating :-)

It's a really good mattress for the price. We got it because our son was complaining nearly every day that his back hurt when he woke up. It weighs 33 pounds, so be ready for that when it arrives. Depending on your stature, you might need someone to help you carry it. The one drawback on the whole thing is that, well, it smells. Really bad. It has a strong chemical smell and allowing it to air out for a couple of days didn't help much. We're putting some fabric softener sheets in there to try to help buffer the smell a bit. Hopefully it'll fade on its own but it would keep me awake at night. Our son doesn't seem to mind.

After shopping around buying another mattress and returning it finding this one at SAMs was great. The mattress was bought for my 6 year old daughter and me and my wife just wish it was a king and we could use it. She sleeps better than us now. My only complaint is they did not have it in stock at our local SAMs we had to order and pay for shipping. Excluding the shipping this is an excellent value. The mattress is very comfortable I have fallen asleep with her reading stories and my wife has to come drag me to our old pillow top.

What a great value for this mattress. Super comfy. I bought for two young girls. They love them. They were packed and shipped well. Very easy to set up. I was concerned about the smell but I didn't need to be. There was no smell at all. Pleased with my purchase.
