The Littens Ultimate Duo 13.5 Tog Emperor is a two-in-one duvet made for people who want one duvet solution for every season. It comes as two separate duvets, a 4.5 tog and a 9.0 tog, that button together to make a combined 13.5 tog for winter. Split them apart and you get a lighter cover for summer.
Filling is 100% Hungarian goose down, hand-picked and washed to European Down & Feather Association standards. This means it's anti-dust mite and hypoallergenic, so it suits people with allergies or sensitive skin.
The casing is 300 thread count cotton jacquard with square box stitching. This keeps the down evenly spread rather than clumped in corners. Finished with a gold piped trim, it's machine washable at 40°C for easy care.
This is an Emperor size duvet measuring 290cm x 235cm. Emperor is larger than a standard King or Super King, so check your mattress dimensions before ordering. It's designed for Emperor size beds specifically, not smaller sizes.
You get two separate duvets: one rated 4.5 tog and one rated 9.0 tog. They have buttons and loops along the edges that let you join them together for a combined 13.5 tog rating in winter. In spring or autumn, use just the 4.5 tog duvet on its own. In summer, some people skip both or use the lightest layer alone.
Yes, it's machine washable at 40°C. Because the duo system splits into two separate duvets, each one is smaller and easier to fit into a standard home washing machine drum than one large combined duvet would be.
The down filling is washed, sterilised and steam purified to European Down & Feather Association standards, making it anti-dust mite and hypoallergenic. This should suit most people with dust or feather sensitivities, though anyone with a diagnosed down allergy should check with a doctor first.
Tog measures thermal insulation. Higher tog means more warmth retention. The 4.5 tog layer suits warm summer nights, the 9.0 tog suits spring and autumn and combining both for 13.5 tog suits cold winter nights. This range means one product covers most of the year.
A small number of reviewers reported feathers or down working through the fabric over time. This can happen with any down product if the casing weave loosens with repeated washing. The 300TC down-proof casing is designed to minimise this, but heavy or frequent washing may increase the risk.
Littens states this product uses 100% Hungarian goose down, not a feather and down blend. One reviewer received an incorrect item (a feather and down duo) due to a dispatch error, but the product as listed is pure goose down filling.
Natural down generally offers better warmth-to-weight ratio than synthetic filling, meaning it feels lighter for the same level of warmth. Reviewers who compared it to old microfibre duvets had mixed views, with some finding it warmer and others expecting more warmth for the price. Quality can vary by batch with any natural fill product.
