Your Options with King Koil

Every good day starts with a great night’s sleep, and you can always rest assured that you’re slumbering soundly on one of the King Koil mattresses from our expertly selected City Mattress lineup. Taking great pride in every mattress crafted, the quality, attention to detail, thoughtfully-sourced materials, and latest technologies combine for unparalleled sleep comfort and support.

All engineered with the ContourFlex Encased Coil System, our King Koil collection of innerspring mattresses provides independent, full-body support with reduced motion disturbance and a personalized feel. Ensuring years of consistent rest and rejuvenation— all of our King Koil mattresses are finished with a handcrafted Tailormade Tufting™ process that prevents shifting or sagging layers for quality that can be felt in every luxury detail.

If you’re primarily a side sleeper, choose the Amesbury Ultra Plush Mattress with several comfort padding layers, including High-Loft Joma® Wool, high-density plush foam, and graphite-infused memory foam. With extra cushioning from the pillow insert and a balanced medium feel, check out the Whitby Euro Top Mattress, which features a breathable cotton topper, a silk-wool blend quilt, and multiple layers of specialty foam. Contouring and adapting with a high level of pressure relief, choose the Wellesley Plush Mattress that includes the moisture-wicking buoyancy of graphite Talalay latex and perimeter-zoned micro coils. Lavishly designed for a luxurious feel, you’ll love the Riverton Lux Firm Mattress or the Brookfield Lux Plush Mattress, both combining natural materials, such as silk, wool, and cotton, along with a signature foam encasement, graphite foam, and graphite Talalay for life-changing sleep in your ideal comfort-feel.
