# BONNVIA BMH1 Double Mattress Topper, 7cm

The BONNVIA BMH1 double mattress topper is listed as 7cm thick, with a support-foam core and a removable bamboo-fibre and polyester cover. Its extra-firm rating and washable cover may suit buyers seeking a firmer surface, but check the mattress dimensions and allow time for the topper to rebound after unpacking.
