  • Solid Edge Support, Ideal For Daily Deep Sleep
Item Thickness: 14.0 Inches Size: King (U.S. Standard)
Really comfortable spring mattress with premium fabric cover. The firmness is ideal for daily sleeping. It cushions pressure points nicely and keeps spine aligned properly. Only minor thing is it needs 48 hours to fully air out and regain full shape, totally acceptable.

  • Best mattress purchase I’ve made this year.
Item Thickness: 12.0 Inches Size: Queen (U.S. Standard)
This mattress is very comfortable. It has a perfect medium firm feel, not too soft and not too hard. The overall quality is really great and exceeds my expectations.
