The mattress has a smell the first week or so if you don't let it air out long enough however once you slept on this mattress for a week you will be amazed I had numbness in my arms and it's completely gone I would wake up at night every hour from the pain and now I sleep tonight through.

I ordered the 12 inch and I have let it sit for more than 3 days. the middle is about 8 inches but the ends are only 5 inches. I honestly did not think it would happen to me. now what ? I'll let you know how the return or refund goes. im so disappointed.

Got the mattress 5 days ago as of today (1/10/21), it has still not risen to the 12” it’s supposed to be at. Currently it sits around 9” on the sides and 7” on the ends. There is also a gap between the foams on one of the ends. I emailed Zinus directly and they said to give it a week. I don’t see this correcting itself in just 2 more days. The card said it was manufactured April 2019. I will update this review in a few days with new measurements and Zinus’s response. Seems like it would be a good mattress but you’re taking a gamble on it being defective or damaged from being in a box rolled up too long.

Five days after I opened the box and settled the matters on the bed it was only 6” when I was told to wait 72 hours to reach 12”. Also, one corner was missing a piece of the center foam, there was an empty space there. I don’t or can’t say the product is bad. What I’m expressing is that the one I received was not good.

My wife and I went on an actual vacation to the Dallas Fort Worth area and stayed with relatives who had purchased this mattress. This mattress gave her such a good rest she slept for most of the vacation. It's difficult for me to talk my wife into going on vacations as she has had four back surgeries and is constant pain. The car ride and then trying to sleep in a hotel bed and then car ride home exaggerates the pain to an unbelievable level for her. Before we left she wanted the details of what she was sleeping on and where to get it. It was available through our local Sam's Club but you have to order it on-line and it is shipped free to your door. We were lucky enough to catch it on sale thanks to Black Friday but would have bought it anyway. Can't wait to see her actually rested here at home where it will be a game changer for her.

This mattress is very comfortable and just the right firmness for me. I have back and hip issues and sleep well on it. The only issue I have is with the smell or as they call it off gassing. Left it uncovered for some time but think that smell is going to be around for probably months.

We bought this mattress about six months ago. At first, it was fine. We had no issues. But now we both wake up with our backs hurting so bad. You sink into the mattress and there's a little support now that it's been used for six months. My husband says when you try to roll over it feels like rolling up a mountain because you sunk down so low into the mattress. I read the reviews and chose this mattress for the price and mostly positive reviews. I wish I would've went with something that was more expensive and better quality maybe it would've lasted longer than six months. We've already ordered a new mattress.

I, however, don't find it that great. Before we bought this mattress we had an adjustable air mattress. We had this mattress for 12 years and had no problems. When one side of the mattress became too soft or firm it was easily re-adjusted. This current mattress can't be adjusted and I find that it is too firm. Problem is, I can't re-adjust the firmness. I should have purchased a 14" mattress. I hear that the 14" is slightly less firm. Also, after about 3 weeks there is still an odor. This odor is not really objectionable, however, it smells like mold. At least to me. This concerns me. I had asked the manufacturer about this odor and received a non-reply. They said the odor should go away in no more than 3 days. OK, like I said, the odor isn't that strong, but it smells like mold. No one can, or will, tell me what the odor is supposed to smell like......plastic, rubber, mold, flowers....? As I stated earlier.....my Wife loves it ...so......I guess it's a keeper.

I have been sleeping on this for about a month. I went from an old "spring" mattress to this memory foam. It was easy to set up and I was able to sleep on it the same night. I am able to sleep on my side again, something I had not been able to do for months since having problems with my shoulder. My sleep is definitely better and the price was reasonable.

We purchased a queen size over a month ago and was waiting until we used it for awhile before writing our review. It is a little firmer that we had thought it would be, but adjusted to the firmness quite well. We originally had concerns over it being too warm, but have not encountered a problem with it, am not sure what it will be like come summer weather. We are very pleased with this mattress and highly recommend it.
