Great mattress with affordable price tag
Very nice mattress with zero odor. Plush padding yet firm. Expanded within a few hours. Great for college apartment living.

Great deal!
For the price, I’m really happy with this bed. It came wrapped and rolled in a plastic sheet. It expanded nearly instantly on unwrapping and I didn’t notice any chemical smells or anything of that naturePros:Cost was low, less than 3 big ones for a king sizeCan’t feel the springsKing size is so spacious!The cover is soft, and pretty cool to the touch.Supports well.Cons:This is a budget bed, and the durability is a little low. Mine arrived with a tear in the corner. It’s cosmetic, so I’m not too bothered and it’ll be covered with a sheet, but I was surprised to see how thin the material is on the sides of the bed. It appears to be non-woven fabric.The bed also sinks down pretty bad on the corners / unsupported sides. So far not a big problem, but noticeable enough.I also bought a 6 inch foam topper for the bed to add a little more poof, since the bed itself has a relatively thin layer of memory foam.Overall, I’m pretty happy with this bed for the price I paid. It was the lowest cost option for the size, a brand new decent king size mattress at this cost is pretty hard to find. We just moved and struggled to get something delivered, this is infinitely better than the floor at a small price point.Hope this was helpful for you!

Ok for the price
Extremely heavy so be prepared. Nice soft bed, yet also firm. No smell. Looks good.

Very nice quality mattress
Really good king size mattress. I have had this for a few months now and it has improved my sleep quality greatly. Was a decent price as well. I would say it is fairly firm but only downside are the edges donât seem as supportive but it doesnât affect the support/quality of the entire mattress. Iâm general itâs firm and hugs your body where you need it to.

Extra Firm!
We’ve had this mattress for nearly 3 months. We had a purple mattress previously but it started to fall apart, and we needed a replacement ASAP. So far, this mattress has met our expectations.The mattress came in a box that was easy to move. There were no weird mattress smells upon opening. We did let it sit the full 48 hours before sleeping on it. The mattress itself has handles on the sides to help move or adjust it after opening the box.The memory foam is FIRM. We prefer firm beds, and this one is definitely firm enough for us. I am constantly rolling in my sleep like a rotisserie chicken, and whether its on my side, my back, or my stomach, I am comfortable. I also sleep near the edge and still find it has enough support for my large frame.Overall we are satisfied with our purchase!

Not firm at all
Not firm at all. Very soft, I let it sit out for over 48 hours and this is more plush than the other plush mattress I bought

Fantastic Mattress
I pruchased this mattress for my daughter’s bedroom as it was time to replace her old mattress. She loves it! It states she is having a better night’s sleep and no back pain in the morning. It is so comfortable that she looks forward to going to bed at night.
