The mattress said it was 6", but even after waiting two full days to let it get to it's full size, the mattresses only got to about 4" tall. The memory foam part is only about 1/2" to an inch high, the rest is regular foam. I bought two of these mattresses for my Captian's bed in the spare room, so overall, sleeping on two of them combine is fine. If I were only sleeping on one, there would be hardly any support. If I ever have to use my Captian's bed as a queen, I'm going to have to buy a topper to add for support. If I had to do it all over again, I think I would have spent a little more money and gotten a better and thicker mattress.

Was a but hesitant to buy a mattress through the mail without testing it out. I was also concerned about it being so inexpensive. However, once I received it, all those fears were proven unfounded. This ie an amazingly comfortable mattress. It said to allow 48-72 hrs for mattress to fully inflate. However, mine seemed to be fully ready within 5 mins. I did wait just over 24 hrs just to make sure Not hot like some memory foam. Great support while conforming to your body for maximum comfort. Strongly recommend.

Absolutely love this mattress! It's a firm mattress, so if you want something soft, I suggest a topper for this mattress. A great feature is when your partner moves, you don't feel it. We ordered the king size, 12 inch, mattress and use it on our adjustable bed frame (head and feet go up and down). This is a great buy! I highly recommend it.

I ordered this 12 inch mattress thank you. It would be a lot better for my back calls I have to have back surgery I have had this mattress about a year or either little less and I am very disappointed it definitely is not what I expected I definitely do not recommend this bed at all if you have back problems do not I repeat do not this mattress it looks like it's quilted like that on the 12-inch but it's only an impression and when I sit on the edge of the bed it almost hits basically the floor but it's not on the floor if that makes sense

Rose to expected height, corners flat. The cover is very soft. Haven't slept on it myself but the person who did was pleased. Not sure about the fiberglass reviews I'm reading. The person who slept on it is VERY sensitive to everything and didn't report any problems. Have it on an 18" platform and it sits high! Have for a spare bedroom so will get minimal use. Affordable!

The mattress arrived on time and inflated perfectly. It was absolutely beautiful. But I had to return it because it was way too soft for me. My fault I did not notice the description said plush. Plush is too soft. Walmart made arranging a pick up very easy, no problem

I can't tell anything at this time. We have not used it yet. We bought it for our RV bed, but we won't be going down to use it for a couple of weeks yet, but I am sure we will be very satisfied. We are also planning on purchasing an 8" memory foam mattress for our bed at home.

I am very happy with this purchase, however I will say that I have only had it for approximately 1 week. It arrived earlier than planned and was at full potential within 36 hours of opening. We purchased it along with the Zinus frame with head board. Everything was easy to put together and it takes all the pressure off my hips, shoulders and back. Feels like sleeping on a cloud and it just the right mixture of firmness and soft. Good quality for the price as we were looking for weeks and had thought about other brands at $1000. Happy with what we did.

I purchased a King Size version of this mattress some 7+ years back, and have really appreciated the benefits from the memory foam allowing the trigger points on my body to relax, yet a certain amount of firmness that supports the spine. I spend several days a week as a caregiver in my parents home, so purchased a twin size version to make sure I get hte same benefits while sleeping away from home.

I read a lot of the reviews on this product thinking I would go with the ones saying it is awesome could be compared to the higher end foam mattresses and so on.... I'd have to completely agree, my husband and I just bought a king size 4 inch topper that not only was cheaper but is way more comfortable than the queen size 6 inch we got for our son. It doesn't feel firm and it doesn't feel like foam I don't even think it got bigger than 4 inch. I was truly disappointed with this product. I wanted to return but loan behold there was no receipt in my shipment box. To be honest it feels almost like sleeping on a full air matress there is absolutely no feeling on it at all.
