What to know before buying
- The listing calls this king size, but its stated dimensions are 150cm x 140cm. Confirm these measurements suit the intended bed before buying. Electrical details are given both as 120W and AC220-240V & 2 x 60W, which are not presented consistently. The stated 9p daily running cost depends on running both sides at the highest setting for three hours and may not reflect other usage or tariffs. The listing claims UKCA and CE certification and a 365-day warranty, but the supplied information does not independently confirm either claim.

- People who want a removable controller for washing the fabric.
Less suited to
