This California king size mattress arrived in a box which made it very convenient to bring to the fifth floor and into the apartment. So far we are very happy with it as it’s comfortable and it seems breathable as advertised. We live in Florida and mattress that prevents overheating is necessary for a good night rest.

I wish that this would have worked out, but it just didn’t! The packaging was awesome, the bed it self seemed like great quality but the top layer of foam just didn’t spread out to the edges of the bed. We thought we would take the cover off and see if there was anything we could do to help, but oddly enough the cover doesn’t come off! It has a zipper, but you cannot unzip it- I just don’t understand what the deal is with that. We took it back to Sam’s and they gave us a full refund and we went with a traditional mattress.

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?

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.

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!

The mattress is very comfortable, however it does not look the same as the photo, the corders are not as straight up and square and it does not fit perfectly on my queen frame from IKEA...nonetheless, I like the mattress and it works for my needs. Would recomend this product to others. The value is great for the price!

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

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.

We bought 5 of these for a vacation rental, one 12 inch and four 10 inch. We’d have bought five 12 inch but only one was in stock. Timeliness and convenience of delivery and set up were great. We slept on a 10 inch for a couple of weeks while there working on the property and found it very comfortable. The quality of materials and construction look good. I expect we will get a number of years of good service from these mattresses. We do love our $4,000 Intellibed mattress at home but these inexpensive mattresses from Sams Club offer a very similar nights rest.
