Extra Thick Duvets are available in three sizes (in selected ranges, only medium & large sizes are available). Duvets are filled with Supersoft Thermal Polyester Fibre to give even more softness, warmth & comfort. Our duvets have removable covers with zip fastenings. The Duvets are fully washable & easy to dry, as the Polyester Fibre will not absorb water. Spare covers are available.
