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.

The bed is just as described and was a great choice--comfy, supportive, just right in terms of firmness. We made the switch to memory foam in order to accommodate our son's shoulder surgery, the recovery from which would require a more supportive mattress. Unfortunately, the bed arrived 2 weeks after we expected it so, although he is enjoying it now, it was not here when he needed it most.

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.

After reading other reviews, we were concerned that the mattress would have a strong, long-lasting chemical odor. Not so!! More importantly it is very comfortable memory foam. We have it in a guest room and our visitors have loved it. One intends to buy one. Pricing was exceptional. It arrived quickly and when promised. Unboxed easily (but be sure to read the directions) and inflated fully in a day or two. Definitely a great product especially for the price.

Just received this and have slept on it a couple of nights. It did take 48 hours to inflate completely. If you sit on the bed, it will sink where you're sitting, however if you lay down there hasn't been any sinking - it stays firm. Since it's only been a couple of days, it will be awhile to determine if it is as good as it seems to be. So far, we're very pleased with it.

The description of this Item was "Zinus Night Therapy 12" Green Tea Zest w/Smartbase Set, Size: King" However, no Smartbase was received and thus this item was not a "Set". That was a disappointment. However, the actual Zinus mattress has proven to be a complete delight and surprise. It came packaged, as all memory foam mattresses, tightly compressed and rolled inside a large box. It was left in the box for about 5 days before being unrolled and although the packaging indicated that it would take 24-48 hours to reach its full thickness, it probably reached 11 1/2" within a few hours. Now, after a few weeks, it has reached its full 12" height on all areas of the mattress except a slight dip in two corners that isn't really a concern. The mattress is surprisingly firm and I love it for that reason. Some people who prefer a softer sleep surface may find the mattress too firm. This mattress replaces a pillow-top mattress that, after only about 3 years was dipping on each side. I'm hopeful this Zinus mattress holds its firmness and shape over time!

I really have to say I truly love the smartbase that came with this mattress it is so lightweight that I by myself was able to unpack it, put it together and take it upstairs all by myself, and this was the king size! The smart bass has these clips that click when the legs lock out and in order to get them to go back down you have to press the button on it so you know it's locked when you're using it. I have had bases similar to this before that were so heavy, and even though the king comes in two pieces, I had to have help moving it. It also breaks down and stores super flat which is so nice if you have to move furniture to paint or you have to move. It does not take up a lot of room stored. I was surprised at how small the box was that it came in when I put it together. The height of the base is 14 inches. The green tea mattress I have to say did not have a lot of offgassing like some of the other mattresses that are similar that I have purchased before from other brands. It comes with directions that tell you it needs to be opened as soon as you get it and let it rest for about 72 hours which I did, it did have a slight odor but that's to be expected for anything that's been wrapped in plastic and that is a memory foam mattress but it was definitely not bad. I could be in the room with it and be in the house without it bothering me. The smell that it did have disputed so fast I was actually really impressed with that. After getting everything set up and sleeping on it for about two weeks I noticed that my back did not hurt as much as it normally does. The mattress is probably more of a medium stiffness not overly soft and not as hard as a medium firm mattress like my previous one was. it does hug you a little bit when you are sleeping so you don't feel a lot of movement from anybody else it's in the bed. The one thing though I did notice that after having it set up for a long time and sleeping on it is that the 12 inch mattress actually measures out to be more of around 11 inches good thing to know for purchasing sheets so you do have a little bit more options in sheets than a normal 12 inch mattress.

Fantastic mattress. Fantastically thick mattress. Firm but gives enough to feel plush and comfortable. I was pleasantly surprised with the excellent quality as I had never purchased a mattress in a bag. What a pleasant surprise. Super glad I went with the 12” as it is very luxurious.

This is the 3rd Night Therapy my husband and I have purchased now. Best sleep ever. It is soft but firm support. Both of us used to wake with back aches on the old mattress, never again since the night therapy ones. Can't stand the soft mattresses that you sink into and wake with a hurting back. This is soft as you climb in bed, but comfortably supports the body firmly but not hard. I reccomend these mattresses, especially if you have back aches.

just bought this for our RV full size, No Smell and easy to walk around in the RV. At first when we opened the box there are 4 layers which was a shock but soon it started to inflate (we opened the bed in place in the RV and watched it unfold. Great value for the money
