Great mattress! Very comfortable. Unrolls and forms quickly. Great value for the money! I was impressed. The smell is a little strong at first (like a chemical smell) but fades quickly! Highly recommend.

I looked for 2 months on Amazon for just the right mattress... and finally took a chance on this one! We went from having a memory foam mattress to this. For us, it is perfect! Not too firm. Just the right amount of plush on top! Have been sleeping great! Do be careful unwrapping! If hubby wasn't in the right place when it "exploded" out of the wrapper, I would be peeling him off the wall! No smell. Expanded to full height immediately. 14" King

The media could not be loaded. This 14" California King mattress is a good value for the money. It was full height within an hour. It sleep well, all positions. It was noted "firm", and I firm, what I wanted. The edges are not too soft, settle approximately less then 6" for my 200lbs. sit on edge, totally acceptable feel, no disappointment. I am relieved the sleep and corners are not soft. No out-gassing smells noticed. The quilt top is nice, however the stitching pattern (depressions) are noticeable, yet not a problem for me at all. This is nice mattress!

Not very firm on the edges. I miss my memory foam hybrid mattress and wish we went with one of those, but this one was a lot let expensive. Overall 4 stars because it’s not super uncomfortable but it’s not my favorite. We had to upgrade from a queen to this king.

This is my 3rd version of compressed mattresses in a bag, so to speak, 3 different sizes. I started with a California King, then Queen, and now a Full-sized. Honestly, I've enjoyed each one over the very high priced mattresses offered at furniture stores. One thing to note is that the softer the mattresses are from the beginning, the faster they break down, leaving you to replace them much quicker. I prefer ones like this brand, that have more support from the onset. They simply last years longer! Also, all mattresses have a 'break in period' of at least 90-days to fully know if they'll work for you. This is where many people make mistakes. I recommend using some type of a topper, if needed, during this period. I've personally found this very helpful to allow me time to assess the mattress. This full-size mattress is for a guest room, so it had ample time to fully expand before it was tried out. I found it very supportive, yet soft at the same time. However, I must say that the box it came in was quite heavy to maneuver by myself when it was delivered. But once two of us unboxed it and set it onto the frame BEFORE we opened the outer packaging, and it all went well. FYI - Please be careful opening the outer packaging so you don't puncture the mattress. It is also worthy to note that the mattress comes with two handle to easily move it, where my others did not. So far, I am impressed with the entire design of this mattress. This company has certainly done their homework, which I greatly appreciate. I feel certain that this mattress will last for many years. And honestly, even if it doesn't, for the price and convenience compared to furniture store mattress prices, I could buy a new one every couple of years. The only downside is that even though they offer FREE-RETURNS, it may not be so easy to do once the mattress is fully expanded. However, I've yet to have to return one. So that's the good news!
