  • Perfect mattress
Color: Grey Item Thickness: 12.0 Inches Size: California King
I live our new mattress, I had spine surgery and I can tell you this mattress was perfect on my spine. I slept so good and I like the spring feel and the edges that help me and my husband who is handicap to get up faster from our bed. I rate this mattress above and beyond and for the price a perfect 10 stars ⭐️ ... show more

  • This mattress is the Truth!
Color: Grey Item Thickness: 12.0 Inches Size: Full
I love the firmness of the mattress, the size and the thickness. I purchased the 12 inch full sized version and after waiting two days for it to fully form, I experienced the most peaceful night of rest. I am a 270 pound man who stands 6 foot 2 and a full time student who also helps to take care of my aged Mom. I needed a comfortable mattress for my back. The individual pockets of coils mixed with foam feel amazing. I did not want to get out of bed to write this review but I had to. Thank you to all who honestly reviewed this item. Your reviews helped me to make my decision. I am purchasing another for my guest bedroom. My only worry is that they will never want to leave. BTW I was worried about my regular full sheet sets would not fit but they do. Thank you Eeen Eeen! ... show more

  • Comfortable bed
Color: Grey Item Thickness: 12.0 Inches Size: Full
I purchased this mattress for our guest room. This is a great quality for the price point. It came quickly and didn’t take long to expand to the full size. Our guests have commented how comfortable the bed has been and they have had no issues sleeping on it. The prior mattress felt like a rock, but this one has just the right amount of firmness and has kept its shape. ... show more

  • Very comfortable
Color: Grey Item Thickness: 14.0 Inches Size: King (U.S. Standard)
I needed a mattress for the spare room and didn’t want to spend a fortune. Mattress comes in a pretty small box so it’s surprising when you unpack and it expands. This mattress is great! It’s the spare room but I find myself going in there and laying on it often. It is a very comfortable mattress. Can’t believe for the price it is such good quality! ... show more

  • Comfortable
Color: Grey Item Thickness: 12.0 Inches Size: California King
We replaced our waterbed mattress with the california king memory foam mattress. It is wonderful. The only thing different is there is no heater. Very easy setup and we slept in it less than 8 hours after setting it up. Great buy.

  • Don’t buy, waste of money!
Color: Grey Item Thickness: 14.0 Inches Size: King (U.S. Standard)
This is the worst item I have ever purchased. I should have read the reviews closer. It is not a firm mattress as it is described. It is incredibly bouncy, the sides have no durability and collapse when you attempt to get out of bed. (Picture yourself rolling onto the floor.). When you lay down in the bed it feels like you are falling into the floor with the mattress collapsing around you. I even purchased a box frame to go under it to build up the stability but it didn’t help enough to want to keep it. Tried to return this but you have to roll it up and get it to fit into its original box. So now I am hoping someone will take it off my hands for free. What a complete waste of money! Don’t buy this you will regret it and won’t be able to return it. ... show more
