Englander plush: classic spinal support, modern build quality.

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.

About this mattress
Englander O’Conner Luxury Plush Box Top 16.5" Mattress
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.
Advanced Cooling Meets Plush Comfort
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.
