I really like the firmness and comfort of this mattress. We kept the box spring from our old regular mattress set and placed this on top of it. The con is that it moves when you touch it. I bought some wide double stick tape to place on the top of the box spring to hold the mattress in place. Have not had the chance to put it on yet so not sure if it works but keep this in mind when buying.

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!

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.

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.

Zinus Night Therapy Green Tea Zest 12" Memory Foam Mattress arrives in a large box ready to use. The box is a little awkward to handle without someone to help, but certainly not more than a regular mattress. The mattress is tightly rolled in a clear wrap, so be very careful when opening the box with scissors or a knife. Upon unwrapping, the mattress begins to expand pretty quickly. Within a few days, it is completely expanded (although I would follow the 72 hour rule before actually using). I did not have any real issues with odor, but we left in a well ventilated area until ready to use. My son loves his new mattress. We have all taken turns testing it out, and it is quite firm with just the right softness. We have already ordered another for another bed in our home. For the price and delivered to your door, this is a win-win!

I really like this mattress. I’ve never seen experienced a memory foam that actually provides support. It’s soft and cushions your pressure points, and also provides support. Great for those who are hot sleepers! My husband who runs hot hasn’t had a single complaint since we’ve switched over. The only downside I’ve found is that the bottom doesn’t have a nonskid surface.

This mattress is very comfortable. It is firm but the top layer is soft, so very comfortable. I have it in the guest room where it won't be used every night so I can't speak to how long it will last. For the price, I am very happy. It arrived quickly.

By far the greatest bed, I am a stomach sleeper and this supports my back and completely relaxes my body. I lay down and within minutes I am completely asleep and sleep all the way thru the night. Even my husband, who is a light sleeper, sleeps great all thru the night. Definitely recommend. The cooling effect is great as well

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.

I’ll admit I was skeptical at first but I really like this mattress. It comes rolled up tightly wrapped in plastic in a box that seems too small to fit a mattress so I had my doubts on the quality. But I was very wrong! This bed is so comfortable! Definitely more comfortable than the mattress it is replacing. I let it air out for a day or so. The smell isn’t bad at first but definitely is noticeable after a few hours. Don’t worry, it goes away by the next day. It’s fun watching the mattress expand. It happens pretty quickly once it comes out of the wrapping, probably 60 percent filled, then continues to expand slowly. The green tea is a nice touch, but I don’t know how long that will last. I went with the 12 inch mattress because I like the extra height and it was perfect for me. The bed is so comfortable. I had the best sleep I’ve had in a long time and it’s been a couple weeks now and I have yet to wake up in the middle of the night, my sleep has been so restful. I was worried there would be a long breaking in period, but since it is memory foam it just conformed to me immediately. It’s the perfect mix of firm but soft where I need it to be like it's cuddling me. I highly recommend giving this mattress a try, it’s been a great experience for me.
