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.
A foam-encased perimeter lets you use the full sleep surface — and sit on the edge to dress.
A reinforced center third keeps the spine aligned across every position.
A tall comfort and support stack means more contour up top and stronger lumbar push-back below.
We deliver, set up in your bedroom, and haul away your old mattress — no extra charge.
A 7/10 firmness — gentle support without sinking. Good for back and combination sleepers, plus side sleepers over 200 lb.
Built for adaptive support and breathability. Every layer is hand-checked before it ships from our warehouse.
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.
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.
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.
