Key Advantages
Why Choose SFERRA Sonno Notte Luxury Firm
- Exceptional build quality — hand-tufted, made in USA
- Natural Talalay latex comfort layer for responsive support
- Individually pocketed coils minimize motion transfer
Why Choose Purple RejuvenatePlus
- 3 inches of GelFlex Grid — enough depth that side sleepers do not compress through to the transition layer
- Widest sleeper-position range in the Rejuvenate collection; genuinely works for side, back and combination
- DreamLayer top softens the grid's first impression while keeping airflow intact
