This 7 cm deep, goose feather single mattress topper is our thickest and comfiest ever topper. Baffle box construction makes it fantastically full and luxurious. Luxurious Goose Feather Goose feather filling is renowned for its incredible comfort and warmth, and widely regarded as the ultimate luxurious bedding option. Our goose feather mattress topper is much thicker than standard toppers, measuring 7cm (3”) deep, so provides a thick layer of lavish cushioning for your entire body. Available in single (90 × 190 cm), double (135 × 190 cm), king (150 × 200 cm) and super king (180 × 200 cm) sizes. Please note all measurements are approximate. Baffle Box Construction This gorgeously comfy topper is constructed using the baffle box method, ensuring that the filling is evenly distributed into ‘pockets’ to prevent clumps of feathers from forming within the topper. Elastic straps at each corner hold the protector against the mattress so that you can guarantee your topper will stay in place between your mattress and your sheets. This goose feather topper is Oeko Tex 100 certified and filled with Responsible Down Standard (RDS) certified feathers.
