King Koil Overture Mattress

This mattress offers a supportive, stable surface that resists sinking. While it uses memory foam for pressure relief, the underlying coil system ensures you feel like you are sleeping 'on' the mattress rather than 'in' it, which is ideal for back and stomach sleepers.

Yes. Graphite is highly conductive, meaning it pulls heat away from your body more effectively than standard foam. Combined with the breathable Tencel cover, it creates a noticeably cooler sleep surface throughout the night.

The Overture is designed with over 1,000 independently encased coils, which act individually to absorb movement. This significantly reduces motion transfer, so you are much less likely to be disturbed by a partner shifting positions.

Yes, this model is fully compatible with adjustable bed bases. The hybrid construction is flexible enough to contour to the movement of the base without compromising the integrity of the coils or foam layers.

The Perfect Contour Reaction coil system is engineered to provide targeted support where your body needs it most. By responding individually to your weight and shape, the coils help keep your spine aligned, which can reduce aches and stiffness upon waking.

King Koil backs this mattress with a 25-year warranty, which reflects their confidence in the materials. The combination of high-density foam and a robust steel coil unit is specifically engineered to prevent sagging and maintain support over many years.
