Kingsdown Onyx Mattress

This mattress is designed for those who prefer a stable, supportive surface rather than a sinking or hugging sensation. While the Euro-top adds a slight layer of cushioning, the core remains firm, providing substantial resistance that keeps your spine aligned without feeling like you are sleeping on a board.

No, the individually wrapped coils are specifically engineered to minimize motion transfer. Because each coil moves independently, movement on one side of the bed is absorbed rather than rippling across the entire surface.

Yes, the gel infusion is designed to dissipate body heat more effectively than standard memory foam. While it won't replace active cooling systems, it helps prevent the heat buildup often associated with traditional foam mattresses.

Absolutely. The mattress features a reinforced perimeter designed specifically for edge-to-edge stability. This prevents the 'roll-off' sensation and provides a solid, supportive surface whether you are sitting on the edge or sleeping near it.

Yes, the hybrid construction of individually wrapped coils and foam layers is flexible enough to work well with most adjustable bases. Its 14-inch profile provides a substantial look and feel that pairs seamlessly with modern bed frames.

The 10-year warranty covers manufacturing defects, such as sagging beyond a certain depth, coil failure, or issues with the mattress materials. It does not cover normal wear and tear or changes in personal comfort preference.
