Ok, so it was delivered and I needed help bring it in because it is heavy. We’ll, I’m old so it was heavy for me, but, we took it out of the bag and we have it 2 days yo expand which it did evenly. It took me only 30 minutes to assemble the bed frame, and we set it up in the bedroom. It isn’t soft or stiff but took us about 4 days to get completely used to it. I sleep on my side and no problemo, it is confortable and no smell came out from it.

The mattress rises to about 10 inches in the middle, but the corners stay partly compressed with obvious separation between the foam layers. It looks nothing like the square cornered, tall mattress in the picture. This is after over a week, not just initially. Having smaller, sloping corners is a detriment to its appearance and usability. The middle is comfortable to sleep on. Just wish it was as represented.

This Zinus 12 inch mattress topper is a great very comfortable, soft but firm at the same time. We put it in our den for extra bed for our guess specially last Thanksgiving week and this coming holiday season.I can’t believe that this just a topper. It could really be a real mattress. Same me money to tell you the truth. Highly recommend product

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.

This memory foam mattress is relatively firm but still has give to your body weight. I thought it wasn't firm enough but my wife thought it wasn't soft enough. We were afraid that it was going to smell of green tea. There isn't a noticeable smell. When sleeping with a partner you don't notice their movements as much as I traditionally have on a spring mattress. Not sure if it passes the "wine glass test" though. The mattress does not get hot at night although it is not cold either. Was this the best nights sleep that I ever had on a mattress? No. Was I comfortable? Yes. If I were at a hotel I'd be fine with a mattress like this. I'm just not sure if its right for me every night. I would recommend this mattress to most people unless you are particularly picky on how your mattress feels and sleeps on. Mattress comes boxed rolled up and is recommended to open within 72 hours. It takes just over a day for it to fully expand to full size.

Only problem, it didn't expand the full 12 inches. After unpacking I let it "rest" as instructed the full 8 hours. It now measures approx. 10 and three quarters inches. As far as comfort goes its pretty good, but I do wonder about it not being cool in the warm weather if it ever gets here. Next question don't know if recommend?

Surprisingly comfortable! We have name brand T. Beds for our kids but I could easily sub it out with this and they’d be great! I like a very firm bed so this wouldn’t work for Hubby & I. But it would definitely work for all our kids and the guest bedroom! Not sure the longevity yet but off the bat it’s comfortable & when you lay down it’s firm for a sec then you sink in a tad. Helps my kids stay in place a bit more when sleeping lol than rolling absolutely everywhere.

Received mattress two days early which was ok but sometimes that may not be the case as it could interrupt your schedule. Unpacked the mattress and let it sit for 48 hours. No smell of foam what so ever. Mattress is firm but conforms to your body. I had no trouble sleeping on my side or back. No stiffness in my shoulders in the morning which I had with our pillow top mattress we replaced.

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!

bought this for 15 year old son along with a platform steel bed from sam's. Mattress came rolled up in a rectangular box which freaked us out a bit because we had never seen this done before. Plus, when we opened the box and unrolled the mattress, it was about 3 inches high. A note included said to let it rest 24-48 hours to allow it to grow to full size...It did just that. :) My son says the mattress is very comfortable.
