Prevent dust and dirt from entering the mattress, keeping it fresh and extending its lifespan. Made from 100% cotton combined with the filling of 3D virgin ball fiber, the HAUZ Royal Sateen Dobby mattress topper innovates by offering support and a soft velvet-like feel. The elastic bands on the corners help with easy application and fitting to various mattress thicknesses, while the square quilting evenly distributes the filling, preventing it from accumulating in isolated spots. Finally, its hypoallergenic properties provide carefree nights of sleep and rest without worry for those with sensitivities.
