We bought two mattresses for our children, one of them took 3 day to fully inflate and the other one is going on its 6th day and still has dents that have not fully inflate yet, I will give it one more day and if it still the same I will sadly have to return it. The mattress that did inflate its a bit firm for my taste, but my daughter loves it. I tried it and even though it’s firm I felt me sinking in it just enough to give my Hip and shoulders support while turning. We are happy with it. :)

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.

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.

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 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.

I was skeptical at first when I saw how compressed it was at delivery. But after it came to shape and we set it up. Boy I was surprised how comfortable it was. I am a side sleeper with hips and knee pain. First night I slept so sound and woke up with much much less pain. Love it, wish I bought it years ago!

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.

I bought this mattress as moved to new place. This is not at all comfortable. I have used many memory foam mattress in past but this one is worst. Corners didn’t stretched properly. I waited long for it and dump the original packing. Now they are asking for original box for return. Totally disappointed.

I was worried when this first came as it was slow to expand but it finally did after a few days. Easily the most comfortable mattress I have ever slept on. Had it for about five months now. I thought I really like my previous mattress until I got this one, I like a firm mattress and this one is firm but it has a level of softness to it that makes it absolutely perfect.

First time buying a bet in a box but needed a mattress that would transport in the back of our jeep to our new ranch. I was very skeptical but glad I took the risk. Mattress works great and is very comfortable! Our first new mattress in years and we are thrilled!
