10.5 Tog All Season Double Duvet, 200 x 200 cm, Anti-Allergy

The GG Gonzalo Gracia double duvet is number seven in this guide. It is listed as a 10.5 tog, 200 x 200 cm double with hollowfibre filling, priced at £16.99, and it carries 4.2 out of 5 from 4,090 Amazon ratings. Every duvet in this guide is 10.5 tog, so the tog number tells you nothing about which one to pick — what separates the ten is size and how straight the listing is. Here the size holds up: the title says double, the title says 200 x 200 cm, and the item type field says 200 cm x 200 cm as well. Nothing in this fiche describes a smaller bed by accident, which is more than at least one other listing in this guide manages.

The contradictions sit elsewhere. The Seasons field reads "All" and the recommended uses field reads "Bed, Winter", while the fabric warmth description reads "Lightweight" — one duvet sold as your only duvet for spring, summer, autumn and winter, with Amazon's own warmth field calling it lightweight. The care instructions say "Do not Wash, Tumble Dry on Low Heat", yet the fifth bullet promises easy care and "effortless clean-ups". The Fabric Type field, meanwhile, reads "Corovin Polypropylene (Tee Bage Type)", which tells a buyer less about a duvet than any other line in the fiche. In the rating histogram, 67% of ratings are five-star and 9% are one-star. Everything on this page comes from the Amazon listing and its customer reviews — we have not tested the duvet ourselves.
