Our Bed Mattress Topper adds a luxurious extra layer of softness and cushioning to your mattress. With a 100% breathable soft top cotton surface allowing the air to pass through and a 10cm thick box knitted design to hold the fillings in place, you can get a restful sleep, every night. The box stitched design allows the filling to be evenly distributed even after washing, for a more comfortable night’s sleep experience.
