What to know before buying

Listing details to confirm

The title calls it King Size XL, but the supplied dimensions are 165cm x 137cm. Customer feedback also differs on whether its size suits a double bed, so compare these measurements with the intended mattress before ordering. The product description claims UKCA and CE certification, a 365-day warranty, overheat and overcurrent protection, and a cost of 8p for three hours on the highest setting. Those claims are not separately verified here. Follow the stated low-temperature washing condition and detach the controller first.

Who is it for?

A good fit for

Buyers seeking a bed-warming blanket with three straightforward heat settings and tie-down straps.
People who want a detachable controller and a stated machine-washable blanket.

Less suited to

Buyers who need a confirmed fit for a particular king-size mattress, since the listed dimensions are 165cm x 137cm.
People who want dual-zone control or a wider range of heat settings.

Customer feedback reports comfort and warmth, with some customers also describing the blanket as good value. Views are mixed on size, heating performance, durability and whether the straps stay put, with some reports of early failure and difficulty attaching them. For buyers, this makes it worth comparing the stated 165cm x 137cm dimensions with the bed and considering that the three heat settings and tie-down straps may not resolve fit or attachment concerns. The generally positive aggregate ratings sit alongside a meaningful spread of lower ratings, so they do not remove those practical uncertainties.

Frequently asked questions

What size is this heated blanket?

The listing gives dimensions of 165cm x 137cm. Compare those measurements with your mattress, as the King Size XL title does not establish fit.

How many heat settings does it have?

Three settings, operated using the controller.

Can the blanket be machine washed?

The listing says the controller detaches and the blanket can be machine washed at low temperatures. Remove the controller before washing.

Does it have an automatic shut-off timer?

No timer is specified in the supplied product details. The listing does claim overheat and overcurrent protection, but this is not the same as a timer.
