Key Advantages
Why Choose Birch Elite Natural
- Three GOLS-certified organic latex layers plus a steel microcoil layer — the most comfort material in the Birch range
- Plush quilted organic cotton Euro top over natural New Zealand wool
- Zoned lumbar support and full perimeter reinforcement in the 8-inch coil base
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
