Best heated blankets

Top pick: Bedsure Ribbed Heated Blanket — six heat levels, ten timer settings and an 8-hour auto shut-off, so it's the easiest to leave running while you read or doze on the sofa. Nearly 700 ratings back it up, and the 240 GSM flannel feels substantial rather than thin.

Who the others suit:

• Bedsure Solid Flannel — the crowd favourite (1,200+ ratings) if you want simple, soft warmth with a short 3-hour shut-off.
• Bedsure Striped Flannel — the cosiest of the bunch, with a sherpa reverse for cold rooms.
• Sunbeam Bubble Faux Fur — best if you want a plush, decorative throw for a bed or chair.
• Warmrest / Westinghouse throws — the budget route, with 9 and 6 heat levels respectively.
• HeatX — the pick if you'd rather have a full/queen/king size than a throw.

For home use, favour a timer plus auto shut-off and a washable cover; skip anything without a stated shut-off.
