Prevent dust and dirt from entering your mattress, keeping it fresh and extending its lifespan. The HAUZ Royal Sateen Dobby mattress topper is made from 100% cotton combined with 3D virgin ball fiber filling, offering support and a soft velvet-like feel. The presence of elastic corners helps with easy application and adaptation to various mattress thicknesses, while the square quilting evenly distributes the filling, preventing it from clumping in certain areas. Finally, its hypoallergenic properties will provide worry-free nights of sleep and rest without stress for those with sensitivities.
