Buying Guide
Synthetic Duvets
Hollowfibre, Healthguard, Superbounce, Microfibre. They're non-allergenic so they're perfect if you're allergic to feathers and down, or if you wash your duvet frequently. Duvets with synthetic fillings are washable at 60°C – the temperature at which dustmites are killed.
Natural Duvets
Natural fillings are softer, warmer, lighter and more comfortable and they usually last longer than synthetic fillings.
Our fillings range from duck feather to the finest goose down.
All Seasons Duo Duvets
They consist of 2 separate duvets – a lightweight for summer and a warmer one for autumn and spring. For winter months you simply use the duvets together for extra warmth.
Which tog do you need
4.5 tog – 7.5 tog – Lightweight duvet suitable for summer use.
10.5 and 13.5 tog – Medium-to-warm weight for use all-year-round. Ideal in homes with central heating, or for those who share a bed.
