Key Features

Split-Head Design for Couples
Enjoy dual-zone adjustability at the head — each sleeper can raise or lower their side independently — while the shared foot section keeps the base connected for a smooth, cohesive sleep surface. Ideal for couples who read, relax, or recover at different angles without compromising closeness.

5-Zone Support Coil System
Serta’s advanced 5-Zone Support Coil System provides targeted reinforcement for your back and body. With BestEdge® Foam Encasement, this hybrid delivers consistent, edge-to-edge stability so you can enjoy every inch of the mattress in comfort.

Plush Pressure-Relieving Foam
Layers of premium, high-density memory foam conform to your body’s shape, relieving pressure points in the shoulders and hips. This deep contouring comfort supports side sleepers and anyone who prefers a soft, cushioned feel.

CoolFeel™ Cover & Carbon Fiber Memory Foam
Stay comfortably cool all night long. The cool-to-the-touch CoolFeel™ Cover and Carbon Fiber Memory Foam draw heat away from the body, keeping you refreshed through Houston’s warm nights.

Motion Control System
Engineered to absorb movement, the 4500 Hybrid minimizes partner disturbance — a must-have for light sleepers and couples with different schedules.

Flex Adjustable Base Included
The included Flex Adjustable Base transforms your bed into a personalized wellness system:

• Power Head Lift & Foot Lift for ergonomic comfort

• Power Lumbar support for lower-back relief

• Zoned Massage for relaxation and circulation

• Built-in Sound Speakers for white noise or music therapy

Together, this mattress and base create a luxurious, restorative sleep experience designed for relaxation, recovery, and rejuvenation.
