The Englander Everest Luxury Extra Firm Euro Top Mattress is a extra-firm innerspring mattress built for stomach sleepers and plus-size sleepers needing maximum lift. 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 9/10 firmness — supportive top with minimal contour. Best for back and stomach sleepers, plus heavier sleepers who want less hug.
Built for adaptive support and breathability. Every layer is hand-checked before it ships from our warehouse.
The Everest Extra Firm is the firmest mattress in the Englander luxury tier, combining copper-infused memory foam with Englander Edge® Technology for a firm sleep surface with advanced cooling. This is where Englander’s 130-year heritage meets modern sleep technology. Copper naturally conducts heat away from the body and provides antimicrobial protection, while the Englander Edge® reinforced perimeter delivers the strongest edge support in the lineup.
The Everest uses copper-infused memory foam rather than standard gel foam. Copper is a superior thermal conductor — it moves heat away from the body faster than gel, and it naturally inhibits bacterial growth on the sleep surface without chemical treatments. The euro top construction means the copper foam comfort layer is sewn flush with the mattress edges for a clean, structured appearance. The extra firm comfort level (approximately 9/10 firmness) provides the flattest, most supportive surface in the Everest collection, with minimal cushioning between you and the coil support system.
Stomach sleepers who need the firmest possible surface. Back sleepers over 200 lbs who compress softer mattresses too deeply. Hot sleepers who want firm — copper cooling + firm surface = coolest combination. Sleepers stepping up from the Amesbury Firm who want copper cooling and Englander Edge® support.
