Key Advantages
Why Choose Helix Dusk Elite
- ErgoAlign Contour Layer and zoned coils aimed squarely at lumbar support
- Microcoil pressure-distribution layer between high-density foams
- Up to 1,000 extra-firm wrapped coils with full perimeter reinforcement
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
