Why Horizon

Comfort with a clear point of view.

01

Cooling from the cover down

AeroSync Climate Management and AeroTherm cooling gel memory foam keep temperature regulation central to the design.

02

Firm without feeling flat

A measured layer of contouring comfort meets a steady support profile, so you feel held up instead of swallowed.

03

A stable hybrid foundation

ComfortBridge support foam and the MATRIX BASE precision coil array create responsive structure across the sleep surface.
