From Mattress Overstock Kentucky

- Align+ memory foam for pressure relief at hips and shoulders
- All-foam construction isolates motion so a partner's turn barely registers

- Cozy knit cover; Breathe Flex Foam (zoned, open-cell); Align+ memory foam; high-density Casper Core base; CertiPUR-US certified foams
- Fit
- Eleven inches tall; true medium, about 6 out of 10 on firmness; takes a standard fitted sheet
