The Englander Allendale Luxury Ultra Plush Box Top Mattress is a plush innerspring mattress built for side sleepers and combination sleepers. It pairs a quality comfort system with a responsive support core for nightly support that doesn't pack down. At 17", 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 breathable quilt and gel-infused top draws heat away so you don't wake up hot.
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 3/10 firmness — soft enough to cradle hips and shoulders. Best for side sleepers under 200 lb.
Built for adaptive support and breathability. Every layer is hand-checked before it ships from our warehouse.
The Allendale Ultra Plush Box Top is the most luxurious mattress Englander makes. At 17 inches with 100% natural copper Talalay latex, Phase Change Cover, 3° Cooling Coils, and an ultra plush box top, it delivers the deepest, most advanced comfort in the entire lineup. $2,499 Queen — the same price as the Firm — makes it an investment in the best sleep experience Englander’s 130 years of engineering can produce.
The ultra plush box top creates the deepest cushioning in the Englander lineup, approximately 2/10 on the firmness scale. Natural copper Talalay latex provides the comfort layer rather than memory foam. This matters because Talalay latex responds instantly (no slow sinking), naturally resists body impressions over time, and allows airflow through its open-cell structure. The copper infusion adds antimicrobial protection and thermal conductivity. Ultra plush mattresses normally trap heat — the Allendale counteracts this with Phase Change Cover (active temperature regulation), 3° Cooling Coils (heat dissipation through the core), and the natural breathability of latex. Englander Elite Edge maintains edge stability on this tall, soft profile.
Side sleepers who want the absolute best — natural latex pressure relief with the most advanced cooling available. Hot sleepers who love plush — the only ultra plush mattress with Phase Change + cooling coils + copper latex. Long-term comfort investors — natural Talalay latex maintains its properties for 15-20 years vs 7-10 for memory foam.
