Key Advantages
Why Choose Personal Comfort A8 Number Bed
- 45 firmness settings per side, finer than Sleep Number's scale
- 25-year limited warranty with individually replaceable components
- Typically $800–$1,200 less than a comparably equipped Sleep Number i8
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
