About this item

• 【Cool & Comfortable Sleep】The mattress twin xl features memory foam that enhances support while maintaining comfort, helping to relieve body pressure and giving you the feeling of lying on a cloud. The fiberglass-free cover is softer on the skin and more breathable, keeping you cool and refreshed all night long.


• 【Strong Support】koorlian has reinforced the twin xl hybrid mattress’s edge springs for greater strength and durability, preventing sagging or sinking that could shorten its lifespan. This medium-firm mattress is equipped with individually wrapped pocket springs, offering quieter, more stable performance than traditional innerspring designs, allowing everyone to enjoy 8 hours of comfortable, restful sleep.


• 【Pain Relief】The 7-zone support system offers enhanced protection for the spine. Whether you sleep on your back, side, or stomach, it provides ergonomic, scientifically designed support for your head, neck, shoulders, waist, hips, legs, and feet. By relaxing tense muscle groups, it helps ease lower back soreness, shoulder and neck stiffness caused by prolonged sitting or standing, allowing you to enjoy baby-like sleep quality.


• 【Easy Assembly - 12 inch Twin XL Mattress in a Box】Size: 80\' x 39\' x 12\' The mattress arrives vacuum-compressed and rolled in a box for easy transport and setup. Simply unbox, remove the packaging, and allow 48–72 hours for the mattress to fully expand to its original shape—then enjoy restful sleep. Measurement method: After full expansion, measure from the bottom of the mattress to the highest point on the surface.


• 【120-Night Trial & 10-Year Warranty】We offer a 120-night trial and a 10-year warranty, and our mattress is CertiPUR-US certified and odor-free. If it’s not the perfect fit for you, we’ll make it right—so you can trust koorlian and enjoy a restful, worry-free sleep.
