Sealy Posturepedic Hybrid Sonterra King Mattress with Head Up Only Base

A hybrid mattress offers the "best of both worlds" by combining the targeted support of encased coils with the pressure-relieving comfort of memory foam. This specific model features PrecisionFit Coils that adapt to your body's natural alignment and Sealy memory foam that contours to your unique shape. This combination is particularly effective at reducing motion transfer, making it an excellent choice for couples who don't want to be disturbed by a partner’s movement.

A "head up only" base allows you to elevate the top portion of the mattress with a remote, which is ideal for lifestyle activities like reading, watching TV, or working on a laptop in bed. From a wellness perspective, elevating the head can also help alleviate common sleep issues such as snoring or acid reflux. Because this base is a streamlined 4-inch profile, it provides these ergonomic benefits without adding significant bulk to your bed's overall height.

This mattress is an excellent option for those seeking back support, as its design was inspired by orthopedic specialists to improve posture and spinal alignment. It utilizes MaxSupport Technology, which provides extra reinforcement where you need it most. The medium-firm feel offers a balanced level of support that is generally recommended for back and multi-position sleepers who require both cushioning for their joints and a stable foundation for their spine.

Most adjustable bases are designed to be "zero-clearance" or "platform-ready," meaning they can often fit inside standard panel or slat-style bed frames. However, because this system includes a motorized base, you should ensure your current frame does not have internal storage drawers or fixed foundations that might obstruct the base. Based on our expertise, we recommend measuring the internal width of your frame to ensure a perfect fit for this King-sized 76"w x 80"l setup.

This mattress features a DuraFlex Coil Edge, a high-density flexible coil border that surrounds the mattress. This reinforced edge serves two purposes: it provides a solid seating surface for getting in and out of bed and maximizes the usable sleep surface. For an adjustable bed, this flexible edge is critical because it allows the mattress to bend seamlessly with the base without compromising the structural integrity of the sides over time.

Yes, this mattress is designed with features specifically for temperature regulation, which is essential for shoppers in warmer regions like Florida or Texas. It features a Cool-to-the-Touch Cover integrated with MoistureProtect technology. This system is engineered to pull moisture away from your body and maintain a refreshed sleeping surface, helping hot sleepers stay comfortable throughout the night.
