I was very anxious/nervous to try this bed. I have never had a full memory foam mattress(bed in a box). We ordered King size, which we've never had before(best idea ever), as we always have littles sleeping with us. Assembly of the smart base was quite easy. The directions were straightforward. The opening of the mattress was a bit chaotic, but I think that also has to do with the size and me being tiny trying to do it alone. I did not notice a scent from the mattress, which they said may be a problem for people. Once opened, the matress fluffed up with no issues. It fits completely on the smart base. The smartbase gives about a foot high of storage space beneath it, my kids have been using it as their hideout/tunnel. We love the amount of space we have. The memory foam does cradle you quite nicely. I prefer a firmer bed and my husband prefers softer. This mattress is satisfactory for both of our needs. We haven't noticed the "cooling effect" as much. I do believe that is because our previous bed had a cooling layer, so this mattress it isn't as prominent. For the price and what you actually recieve, this is a great set. Which I do believe will hold up quite well. Excited to continue using this bed set.

This mattress is not even on all sides, I get 9" on one side, 10" on another, almost 11' on another, but never 12" which was advertised. It makes you feel like you're going to fall out of bed. I normally sleep on the left side of the bed, but since getting this mattress, I have to try and stay in the middle, so I don't roll off. I spoke to customer service, they gave me a percentage off, but this bed is not worth it. I wish I would've just asked for my money back, I'm very unhappy with this mattress!!! Thank you Adam for your help, but this mattress is horrible, in my opinion. I would not recommend it to anyone☹☹‼️

Had we not read the reviews prior to purchasing a mattress, we would have never chosen this one. It comes vacuum packed. Be sure you have it setting where you want it before removing the vacuum pack. It becomes its true size within seconds. Ours was ready to sleep on within the hour. We also ordered the 4" box spring that requires some assembly to go with it. Perfect height for a young child! There was no odor at all?? We love it!

This 12 inch memory foam mattress is SUPER comfortable! It came in a relatively small box (for a full sized mattress) but when we opened it, within an hour or so it had expanded quite nicely. It took overnight for it to go to full height and be sleep ready. I use this for my 11 year old and it is perfect! It has a decent firmness to it, but also a nice softness (it might be a little too much for some people). My only concern, and this is a very small one, is that the edges are not that sturdy (as you can see in the pictures). This is not a bed for sitting on the edge, but how many people really care about that?

Heated over night but an over fill matress pads help, it's really good no more back pain, in the morning more energy to just wake up in go to work I used to sit down for the back pain relax stretch now get up in go.. I recommend this matress it's really good and a good price too.

The mattress was dumped , in the box, on my porch unannounced. The mattress had to be pried open, did not unroll and instantly expand. After a week plus it has expanded to 8-10 inches thick, not 12 and the corners are still deformed. I emailed Zinus who promptly referred me to Sam's Club online who quickly refunded my purchase. I upgraded to a Zinus 14 inch mattress, still waiting for it to be delivered.

Great mattress. Very firm. Provides great support while also cradling you in while you sleep. Definitely good value for the money. Will be looking into replacing my other mattresses with this one when we need to. Just me sure to allow the mattress to fully inflate and breathe before covering with sheets. As all foam items go there is a little bit of a chemical smell but it goes away as it airs out.

This arrived in smaller packaging than I was expecting but expanded to full once opened. I wasn't sure how I would like the memory foam after using a pillow top for a few years but I was amazed at how well I slept. I use a water pillow which causes indents on my pillow top but I didn't have any of that on this mattress. Very comfortable and sturdy.

This is the second one of these that we have purchased! The first is still in my daughter's room in our home (she loves it!). The new purchase is in her apartment at college. We had it delivered to the apartment on the day we were moving her in and setting it up was a breeze.

I couldn’t believe that a mattress that is delivered rolled up in a box could be a comfortable and good quality mattress. I was completely blown away when I unpacked this mattress and tried it out for the first time. I have to say that this is probably one of the most comfortable mattresses that I have ever owned. It contours to your body so well that it feels like you are literally floating on a cloud. I would highly suggest this mattress for anyone looking for a high quality mattress for a relatively reasonable price. I would highly suggest this mattress to anyone looking for a good night sleep.
