  • QUALITY AND VALUE FOR GUEST ROOM
Really nice quality and comfortable for our guest room. Unpacking was easy, with my daughter and husband doing the muscle part of moving the box into the BR for set up. It fits the old frame nicely, and we left the box spring under the new mattress for a little more height. The sale price made this the best bedding decision we've made in decades! ... show more

  • Great for price
Size: California King Style: 14 INCH
The media could not be loaded. It deflated quickly but remained firm and comfortable. I was initially worried about ordering a bed in a box, but ultimately, it was worth the price.

  • Soft but probably going to be ok
Size: Twin XL Style: 12 INCH
Well it is only $200 and we did just want a no-frills spring mattress. So far it feels very comfortable and we cannot feel the springs. We wanted to avoid those silly hybrids with the 10 inches of foam to focus on the preferred feeling of springs. So this just may be perfect. Craftmanship could be a bit better as they do not include any handles on the side for carrying. ... show more
