Best heated mattress pads

Top pick: Air-Lock Multi-Zone Heated Mattress Pad (Queen). It's the one I'd buy for a normal bed: a true queen size, multi-zone warmth so each side can be set differently, and the strongest owner feedback of the mainstream pads here. If you want the safest bet on quality, start there.

Who the others suit:

• Beautyrest Heated Mattress Pad — the budget route; comes in Queen, Full, King, Twin and Twin XL, so it's easy to match any bed.
• Biddeford Heated Mattress Pad — the value workhorse with the biggest review base, if you'd rather trust a long track record than a few glowing ratings.
• Costway Dual Controller — for couples who both want their own dial and a long auto-off timer.
• Vevor King — if you have a king bed and want simple, no-fuss warmth.
• EMF-Free King — for anyone who specifically wants a low-EMF design and a plush micro-velour surface; it's the premium, specialist choice.
• Serta Twin XL — for a dorm or adjustable base, with a waterproof top.
• HeatSync Wi-Fi pad — skip it for a bed; it's a small USB-powered pad, not a full mattress cover.

Check the size on the card before ordering — several of these are twin or king only.
