Key Advantages
Why Choose Serta Classic Mattress (Enhanced)
- Gel memory foam adds real pressure relief over the base Classic
- Only $100 more than the Standard at queen
- Wrapped coils keep motion transfer moderate
Why Choose LuxeErgo 3400 Hybrid
- Genuine dual-spring construction — micro springs over full-size support coils, not a foam-over-coil shortcut
- Hand-tufted to order in the brand's own Dewsbury factory rather than imported
- 31cm profile with a hand-stitched border gives unusually strong edge support for the price
