Product Overview
The Serta Mattress Cascade Range Extra Firm Twin XL delivers hotel-quality sleep with advanced support engineered for your best rest. Its Q4 Support System features 860-density 4-in-1 coils that distribute weight evenly while five zones of alternating firmness cradle your body's natural curves. CoolFeel fabric wicks away heat throughout the night, while a layer of high-density support foam provides the perfect balance of cushioning and support. This extra-firm mattress works seamlessly with adjustable bases, giving you complete control over your sleep position. Whether you prefer firmer support for back sleeping or need targeted pressure relief, the Cascade Range adapts to your needs while maintaining its shape night after night.
