  • It’s very firm and comfortable as well
Color: White Item Thickness: 14.0 Inches Size: King (U.S. Standard)
I was very pleased with this mattress it’s comfortable, it didn’t take long for it to fully expand and it didn’t have any strong chemical smells. I got an 18 inch frame to go with it and I love it l.

  • Amazing quality for price
Color: White Item Thickness: 14.0 Inches Size: King (U.S. Standard)
This mattress was so easy. Add to cart. Open box. Use plastic tool to open the plastic cover on matress. Wait at least 24 hours to let matress air out and expand. It feels perfect still after a few days.

  • AMAZING Mattress!
Color: White Item Thickness: 12.0 Inches Size: Full
Purchased this for the top bunk of a guest bed. Much to our surprise, it was so comfortable we had to order more for other beds in our home. The best part - there was absolutely no off-gassing (NO SMELL) upon opening! LOVE, LOVE this mattress!

  • I am so angry with this purchase. Product is not what I expected.
Color: White Item Thickness: 14.0 Inches Size: King (U.S. Standard)
The media could not be loaded. I received the mattress on time and in a good package. Cheers to that. On the other side, it arrived on Tuesday, so given 48-72 hours, that should be ready on Friday. I went on Vacation on Thursday night and returned on the following Tuesday, and 1 week after opening the package, the Mattress still did not have 14 inches expanded! And it is not as firm as I’ve imagined. I totally regret this purchase. Do not recommend, unless you’re satisfied with low quality products. ... show more
