A firm innerspring from Englander — pressure relief without the heat.
The Englander Everest Luxury Firm Box Top Mattress is a firm innerspring mattress built for back and stomach sleepers, and plus-size sleepers. It pairs a quality comfort system with a responsive support core for nightly support that doesn't pack down. At 14", it sits in the premium profile range — generous enough for adjustable bases yet still easy to sheet.

About this mattress
Englander Everest Luxury Firm Box Top 14" Mattress
The Everest Luxury Firm Box Top combines copper-infused memory foam with a box top comfort layer for firm support with a touch of surface cushioning. The box top is a deeper version of a euro top — providing slightly more comfort material while maintaining the firm foundation. Copper cooling technology and Englander Edge® reinforced edge support are standard across the Everest lineup.
Copper Cooling + Box Top Comfort
The box top design adds more comfort foam than the euro top Extra Firm model, creating a firm mattress that has just enough surface cushioning to take the edge off without sacrificing support. The firmness sits at approximately 7-8/10 — firm but with a subtle comfort layer. Copper-infused memory foam provides the same thermal conductivity and antimicrobial benefits as the Extra Firm, with more contouring at the surface. Englander Edge® Technology ensures the full surface is usable with no roll-off.
Construction
- Cooling Fabric Cover — Temperature-regulating surface
- Box Top Comfort Layer — Deeper comfort zone than euro top for moderate cushioning on a firm base
- Copper-Infused Memory Foam — Cooling + antimicrobial in a firm configuration
- Supportive Spring System — Zoned coil support
- Englander Edge® — Reinforced perimeter
Who the Everest Firm Box Top Is Best For
Back sleepers who want firm with a touch of comfort — firmer than the Cambridge, softer than the Extra Firm. Couples who need the Englander Edge® for full surface use. Sleepers who tried the Extra Firm and want slightly more cushioning without going plush.
