Sealy Mattresses Streamside Firn King Mattress

The Streamside Firn King is specifically designed for back and stomach sleepers who require a medium-firm surface. Side sleepers may find this firmness level too rigid, as it lacks the deep contouring typically needed to relieve pressure on the shoulders and hips.

The PrecisionFit Encased Coil System allows each coil to move independently. This design significantly reduces motion transfer, meaning you are less likely to feel your partner moving or getting in and out of bed.

The included 5.5-inch low-profile foundation provides a sturdy base for the mattress while keeping the overall bed height lower. This is ideal for those who prefer a more modern, streamlined aesthetic or for individuals who find it easier to get in and out of a lower bed.

Yes, this mattress features integrated gel foams designed to dissipate heat and regulate your temperature throughout the night. Additionally, the moisture-protecting cover helps keep the sleep surface fresh and dry.

This set comes with its own low-profile foundation, which acts as the support base. It is not compatible with adjustable bases, so it should be placed on a standard, supportive bed frame or platform that can accommodate a king-sized mattress and foundation set.

Center Zone Support is engineered to provide reinforced reinforcement under the heaviest part of your body. By targeting the core, it helps maintain proper spinal alignment and prevents the mattress from sagging prematurely in the middle.
