Very rarely does anything actually help my back stop hurting but this mattress did. It would take 20 minutes for my back to unstiffen every morning with other newer mattress. So went with this one based on reviews and yes it does improve back support. I now wake up and my pain level is so much lower. Within 5 min I feel good. Also I can sleep on my side and not feel back pain in morning. On my other mattress I would have a stiff back all day if I slept on my side. This bed feels a little firm at first but then you slowly sink in just enough.

Purchased this a week ago. Was excited as we have couple Zinus mattresses. I should have ordered this straight from Zinus instead! Who knows how long this was packed in the box. It's been 6 days & still not expanded all the way, suppose to be a 12 inch but only up to 9 so far. Got on the Zinus website & did all they suggested to help it expand, it's lumpy & the corners are all hard. Going to send it back, very disappointed.

I have to say, at first I was not sure about ordering a bed online without trying it first. But the details on the materials that make up the bed and the cost for such quality. This was a driving force to purchase this product. I am glad that I did, the first night sleep was something that my body really missed. I have been able to sleep through the night and feel rested and refreshed in the morning. Again the Best Investment I have made in a very long time. I have already told several friends about this bed and hope they will really consider and purchase one for themselves.

We have had this queen mattress in a box for three weeks and it is a comfortable sleep. The package was delivered right into our home by FedEx making it easy to open and expand for two days prior to use. While the mattress is better than our 30 plus year old one, I’m not sure I would buy it again.

Says it is firm but is not. Bed is soft and spongy, not we were looking for so returned it to sams with no problems (other than loosing shipping cost). Bought a 'soft' version of name brand foam mattress and it is much firmer than this. If soft and sinking is what your looking for than this is a good buy.

We had been needing a new mattress and we decided to take the plunge and go with this one based on the review and online research. We had never owned a bed-in-a-box memory foam mattress apart from a topper we were using in our old mattress.. The mattress arrived quickly, it was well packed, it took shape quickly, and there was no off-gassing--so I thought we were off to a good start.... That's the end of the good news since I've been trying to sleep on this thing for a week and have NOT had one good nights sleep! This thing sleeps HOT, so I keep tossing and turning and waking up multiple times in the middle of the night because I'm baking from my own body heat. Not even turning down the AC or having the ceiling fan on lets me get comfortable. Lucikly we kept our old spring mattress and I finally got a good night's rest. We gave this thing a decent try and I was expecting a lot more based on the reviews, but ti's going back to the store this weekend and it's back to square one for us trying to find a good mattress.

I had put off purchasing a much needed new mattress for several years because of the hefty price of the most popular brand name models. I had no idea I could get such quality for such a low price. This is a great quality bed, ordered at midnight and delivered a day later. Assumed it's flat shape almost immediately and we did not experience any of the strong oder mentioned in other reviews. I highly recommend this mattress.

I purchased this mattress hoping for an inexpensive alternative to the name brand foam mattresses. My opinion is that it is way too soft. You sink into it making it hard to change positions. If you sleep solely on your back, it may be ok, but as one that rolls around, not so much. I will be returning it to get something firmer. But, the Sam's experience was fine. I received it a day or too early and they were good about updating me so I could track the shipment.

We tried a new Serta mattress for $1200 and a sleep number bed for $2000 before trying this mattress. This was by far the best & so much more affordable. Try this before you spend money trying other mattresses if you need a good night's sleep and are uncomfortable on your current mattress. I will buy another one for my kids.

My hesitation was if this mattress would be firm enough for me at 190 lb. I didn't want to buy a big sponge. To my relief, it was the best buy I made all year. This mattress is strong enough for a man. It's as good as any traditional mattress with the added benefits of really eliminating the pain I had in my hip and lower back. I got a steal on Black Friday, but I regret waiting to the end of the year while sleeping on my old mattress.
