Dorma Hungarian Feather Dual Mattress Topper im Test

The Dorma Hungarian Feather Dual Mattress Topper is a two-layer feather bed: a top layer filled with 70% Hungarian goose down and 30% feather, buttoned onto a firmer base layer of goose feather. It is the most expensive Dorma topper we cover, from £170 for a single to £230 for a super king at the time of writing (September 2026), and it is built for softness rather than support.

How the two layers are built

Those details come from the Dunelm product page. The layers attach with buttons and separate fully, which is what makes the top washable in a domestic machine. The whole topper fits mattresses up to 35cm deep. Dunelm does not state a depth, a fill weight or a guarantee for this model.

What 70% down means

Down is the soft cluster from under the outer feathers, and it gives the loft; feathers have a quill and give body. European labelling standards use the down share to decide what a filling may be called. According to the IDFL testing institute’s guide to European labelling standards, a product needs 60% or more down before it can be advertised as a down product under EN 13186, so the 70% top layer clears that bar, while the all-feather base is there to stop you sinking through to the mattress.

Feel and who it suits

We rate it soft, 2 out of 10: the down-rich top gives a deep, hotel-style surface and the feather base adds body underneath. Side and back sleepers who want to sink into the bed are the natural fit. Front sleepers and anyone who needs firmer support for the lower back will find it too yielding. It is unsuitable for anyone allergic to feathers or avoiding animal products.

Feather and down flatten with use, so expect to shake both layers out when you change the sheets. The Dunelm product page names no responsible down standard for this topper, so if sourcing matters to you, ask Dunelm before you buy.

The base being spot clean only is the practical catch, and there is no sleep trial: under Dunelm’s returns policy, toppers are only refunded on a change of mind if returned unused and sealed.
