Key Advantages
Why Choose King Koil Natural
- Natural fibers and latex rather than all petroleum-based foam
- Very good breathability — wool and cotton help wick moisture
- Strong pressure relief without a sinking feel
Why Choose Purple Restore Hybrid
- 2-inch GelFlex Grid delivers firm lumbar support and deep shoulder-hip pressure relief simultaneously — no other material does both
- Open grid lattice means nothing traps heat; the coolest-sleeping mainstream hybrid we test
- Responsive coil unit makes it easy to move on and comfortable for combination sleepers
