What are the best weighted blankets to buy in the UK?
Our top pick for Weighted Blankets in the UK is the Brentfords Weighted Blanket 8kg, Teddy Fleece, 150 x 200cm.
The Brentfords Weighted Blanket 8kg suits adults who want a 150 x 200cm teddy fleece blanket for a double or king bed, with named materials, micro glass beads and stitched pockets on the listing.
The Brentfords Weighted Blanket 8kg is our top pick among weighted blankets because its listing states a 150 x 200cm size, a 100% teddy fleece polyester cover, 100% polyester padding, certified, non-toxic micro glass beads in equally stitched pockets, and a weight guide of 7-12% of body weight. For a super king bed, the Mellie Luxury Weighted Blanket lists 6.8kg at 180x200cm with an Oeko Tex certified 7 layer build and 10 x 10cm pockets; for a single bed, the Brentfords 6kg lists 125 x 180 cm and says it is ideal for adults on a single size bed.
This guide compares six weighted blankets from Brentfords, Mellie, Silentnight, Winthome and Sivio, using what each listing states: weight, size, cover, filling, pockets and care. Stated weights run from 6kg to 10kg and stated sizes from 125 x 180 cm to 180x200cm.
Buying guide
What should you look for in Weighted Blankets?
1Weight: the listings state 6kg (Brentfords 125 x 180 cm), 6.8kg (Silentnight and Mellie), 7kg (Sivio), 8kg (Brentfords 150 x 200cm) and 10kg (Winthome). The weight guides they give: 7-12% of body weight on both Brentfords, approximately 10% on the Silentnight, 10% on the Sivio and ±9% to ±12% on the Winthome; the Mellie listing gives none.
2Size: the Brentfords 8kg, Silentnight, Winthome and Sivio state 150 x 200cm; the Mellie states 180x200cm and its title says super king; the Brentfords 6kg states 125 x 180 cm, which its listing says suits adults on a single size bed.
3Cover and filling: both Brentfords listings name a 100% polyester cover (teddy fleece on the 8kg), 100% polyester padding and certified, non-toxic micro glass beads. The Silentnight names glass beads in a quilted cover, the Mellie micro glass beads in an Oeko Tex certified 7 layer structure, the Winthome glass beads in a 5-layer structure, and the Sivio a flannel and sherpa fleece blanket.
4Pockets: the Mellie states 10 x 10cm quilted pockets, the Silentnight individual pockets and both Brentfords equally stitched pockets; the Sivio says the beads lock evenly into each compartment. The Winthome listing does not mention pockets.
5Care and warranty: the Winthome is hand washable or dry cleanable with water below 30℃, then air dried; the Sivio can be spot cleaned or put in a commercial washer. The Brentfords, Silentnight and Mellie listings give no care instructions, and none of the six listings states a warranty term; the Mellie listing offers an exchange or full refund within 30 days.
Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
These listings state weight, size and filling, but none of the six states a warranty term, and only the Winthome and Sivio give care instructions. Both Brentfords titles carry a disclaimer that the blankets are only suitable for age 3+ years, and the Mellie is sold as the blanket only, per its title.
Our Take
Start with the Brentfords Weighted Blanket 8kg: 150 x 200cm, a named teddy fleece polyester cover, micro glass beads and equally stitched pockets. For a super king bed choose the Mellie at 6.8kg and 180x200cm; for a single bed, the Brentfords 6kg at 125 x 180 cm; for the heaviest option here, the Winthome at 10kg.
