Sealy Mattresses Streamside Firm Mattress

The Streamside Firm King is specifically engineered for back and stomach sleepers who require a firmer surface to maintain proper spinal alignment. If you primarily sleep on your side, you may find this mattress too firm, as it lacks the deep contouring needed to relieve pressure on the shoulders and hips.

Yes, it features a PrecisionFit Encased Coil System designed to minimize motion transfer. Because each coil acts independently, movement on one side of the bed is less likely to disturb your partner.

The gel-infused foam layers are designed to dissipate heat more effectively than traditional foams. While it is not a cooling mattress in the active sense, the material helps regulate temperature to prevent heat buildup throughout the night.

The total height of the set, including both the mattress and the foundation, is 21 inches. The mattress itself is approximately 11 inches thick.

No, this specific model is not compatible with adjustable bases. It is designed to be used with the included foundation or a standard flat bed frame.

Pro Edge Support reinforces the perimeter of the mattress, which prevents that 'roll-off' feeling when you sit on the edge or sleep near the side. It also increases the usable surface area of the bed, allowing you to utilize the full width without feeling unstable.
