Key Advantages
Why Choose Beautyrest Black C-Class
- Best cooling in the Black lineup
- Versatile medium-firm feel suits most sleepers
- BlackICE 4.0 + RightTemp foam combo
Why Choose Purple RestorePlus Hybrid
- 3 inches of GelFlex Grid — enough depth that heavier sleepers and side sleepers do not bottom out
- 3-zone coil unit adds real lumbar reinforcement and shoulder accommodation over the standard Restore
- Same open-lattice cooling as the rest of the range: no foam contacts the body
