Wow, now this is something quite special. A goose feather and down topper, designed to transform your bed into a nest of warmth and comfort. It’s pretty much like sleeping on a cloud. Filled by hand with 85% Hungarian goose feather and 15% Hungarian goose down. Goose feathers are known for their superior lofting qualities. This mattress topper is 7cm deep, encased in a 233 thread count cover with a cassette construction. No we haven’t gone back to the 80’s, this means that the topper has a series of enclosed boxes, filled with lovely feather and down. Keeping the filling in these boxes, ensures that the topper retains its shape. We recommend you take it off regularly (every 10-14 days) and give it a shake, just to freshen it up and re-loft the fillings, redistributing them evenly in each of their pockets. It has elasticated straps on the four corners, so it will fit easily onto your mattress without any huffing and puffing. Please don't worry if your topper seems a little smaller than your mattress when it arrives; this is intentional to ensure a perfect fit once it settles under your sheet. The measurements for all our filled bedding items are for the outer cotton casing. The final product size may be ever so slightly different from the listed size. This is all very normal.
