King Koil Twilight - Firm Euro Top 15" Spring Mattress
King Koil's Twilight is a 15-inch, firm-feel, tufted euro top spring mattress from their Intimate Collection. It offers a supremely supportive and durable sleep experience. Its core features work together to provide consistent, handcrafted comfort that conforms to your body while actively extending the mattress's lifespan.
The Twilight mattress excels in personalized comfort and superior temperature regulation through its use of premium, specialized layers. Comfort is achieved through Graphite Talalay Plush Latex and Hypergel Medium Memory Foam. Crucially, these components—combined with the natural Silk Wool Blend and breathable FlexKnit™ Fabric— are engineered to maximize airflow, wick away moisture and heat, and deliver a consistently cool and plush sleeping environment.
