    • Great Purchase!
This was my first time buying a mattress in a box, and online. After reading the other reviews and how many stars it had, I went with it and purchased it for my guest room. Very impressed with the quality and how easy it was to receive it and set it up. Very comfortable and not too soft.

This mattress is well worth the money. It’s firm, soft and comfortable all at the same time. I purchased king size and I’m not disappointed. You will love it.

    • Comfortable
The bed is very comfortable. The firmness is perfect for me. And it expanded just right. It was delivered in a timely manner. Overall is definitely good quality for the money we spent on it. It has helped me with my back pain issues for sure.

Size: King Style: 14 Inch Firm
Good purchase, i was super skeptical, i usually buy any mattress in person. But, i live in a rural area, and decided why not take a chance? Anyways. No weird odors, came quickly. It did have the bubbles due to the mattress expanding. So, we gave it a good 48hrs before sleeping on it (which i would recommend. Can be 24 or 48 hours). Only thing is, my husband is saying it's definitely not firm like i said it would be due to description, so he's refusing to use a pillow under his head. I on the other hand love it, and think it's firm enough for my liking 🤣. Hope this helps someone ... show more

    • Mattress is sinking! If you are looking for a FIRM mattress Please do not purchase!
My wife is pregnant! And we were looking for a firm mattress based on reviews. Unfortunately, the mattress is extremely soft and not firm at all. If you have any pain you will sink in the mattress and it will not hold your body correctly! sorry. The mattress looks nice and clean, but only for someone who prefers plush and extra soft! ... show more

We bought this for our new home and it did not disappoint! It so easy to take it out of the box and let it rise for a day or two. It is cool and comfortable and you don't feel every time your partner rolls over. Best of all the price was right!

    • Comfy and thick
I got the 14 inch mattress, queen. All of these reviews say it you can feel the medal in it or whatever no that is not it. It’s thick it’s comfortable. I gave it over a day to set up because I know that’s important. Other than that. It was great. I let it lay flat on my floor, so that way it wouldn’t mess up the sides when it was decompressing ... show more

    • The worst memory foam mattress ever
It claims firm, but it is actually soft. The Memory foam layer is very thin, and makes weird wavy wrinkles. These wrinkles are visible even with a fitted sheet on. Very disappointed. I wish I never opened the box, but at this moment, it is too late to send it back. The edge is not firm at all. When I sit by the edge, it sinks badly. Now, I am stuck with this bulky garbage. ... show more
