The Englander O'Conner Luxury 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 16.5", 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 O’Conner Luxury Plush Box Top combines Englander’s most advanced cooling technology with deep plush cushioning in a commanding 16.5-inch profile. The Glacier Phase Change Cover, 3° Cooling Coils, and Copper Memory Foam work together to prevent the heat buildup that typically accompanies plush mattresses. The box top construction adds a deep comfort layer for maximum pressure relief.
Plush mattresses trap more heat because thicker comfort layers insulate the body. The O’Conner solves this with three cooling technologies: the Glacier Phase Change Cover actively absorbs excess heat, the 3° Cooling Coils dissipate heat through the mattress core, and copper memory foam conducts warmth away from the body. The plush box top provides approximately 3/10 firmness — deep, enveloping cushioning that cradles the body. Englander Elite Edge technology maintains edge stability on this tall, soft mattress.
Hot side sleepers who want luxury plush — the O’Conner is one of the few plush mattresses that genuinely manages temperature. Couples who want deep comfort with motion isolation. Sleepers who found the Everest Plush comfortable but want even more advanced cooling.
