Serta Perfect Night Royalstone Extra Firm Tight Top Mattress (Twin XL)

The Serta Royalstone Extra Firm is built for sleepers who prefer a solid, highly supportive sleep surface with minimal sink. Its 1.5" layer of supportive gel foams provides targeted pressure relief for the shoulders and hips while maintaining a firm, stable feel throughout the night. The 1100 3-Zoned Coil System delivers reinforced support where your body needs it most, helping promote proper spinal alignment and reducing pressure on key areas. Cooling technologies, including CoolFeel™ fabric, Serta® Silk Gel Fibre, and breathable gel foams, help pull heat away from the body for a cooler night's sleep. Finished with Total Edge® Foam Encasement, the Royalstone offers dependable edge-to-edge support and lasting durability.
