The Restonic Clayton EuroTop Twin XL Mattress Set delivers durable, reinforced cushioning across the entire surface. The 460 Innersprings are tempered with SpiraLok which creates a stronger more stable mattress and also reduces motion transfer and body impressions. With Airflow fiber, heat dissipates away from the surface for an ideal sleep temperature. Bring this home for a restful night of sleep! Set includes mattress and foundation.
