Heated blanket buying guide: size, timer and safe use

Who a heated blanket suits

A heated blanket warms the person rather than the room. That makes it useful for someone who feels the cold while reading in a chair, watching television or settling into bed, while others in the home prefer a cooler room.

It suits people who can feel warmth reliably, notice when they are too hot and use the controller without help. For anyone who cannot, a different way of keeping warm is safer.

Family members buying a gift should think about who will set the controller each day. If the user finds small buttons or menus confusing, a simpler option or a non-electric throw may be the kinder choice.

• Someone who feels cold in a recliner or on the sofa
• A partner who runs colder than the rest of the household
• A cool bedroom where you want warmth only where you sit or lie
• Not for someone who cannot sense heat or use the controls

Heated throw blanket or electric blanket for the bed

A heated throw blanket is smaller, usually sized for one person in a chair. An electric blanket for the bed is sized like a regular blanket and may have one controller or two for each side.

Think about where you will use it most. A throw is easy to move between rooms and to wash. A bed-size blanket covers more, but the cords and controller need a safe route by the bed.

If two people share a bed and want different warmth, a dual-control blanket lets each side set its own level. For a single sleeper in a chair most evenings, a throw is often all that is needed.

• Throw: one person in a chair, sofa or recliner
• Bed blanket: sized Twin to King, sometimes with dual controls
• Mattress pad: heats from below, covered in a separate guide
• Choose the size for the main use, not the largest available

Features that matter most

Look first at the auto-off timer. A timer turns the blanket off after a set time, so it does not run all night by accident. Next, check the heat levels and whether the controller has large, clear buttons and a readable display.

Then check the safety mark. In the US, look for a listing from a recognized testing lab such as ETL or UL, and for overheat protection. Finally, read the washing instructions before you buy.

Cord length matters more than people expect. Measure from the chair or bed to the nearest outlet so the cord can reach without crossing a walkway or running under a rug.

• Auto-off timer choices that fit how you use it
• Clear controller with buttons you can see and press
• Recognized safety certification and overheat protection
• Detachable cord so the blanket can be washed
• Fabric you find comfortable against the skin

The verified heated throw at a glance

We could match one heated throw listing to its maker's page. The facts below come from Westinghouse's product page and the Amazon title. We have not tested it.

One detail differs between the two: Westinghouse names the color Dark Grey, while the Amazon title says Charcoal. Check the model number on the listing before buying.

At 50 by 60 inches, this is sized to cover one seated adult, not a bed. If you want warmth across a mattress, look at bed-size electric blankets or a heated mattress pad instead.

• Size: 50 by 60 inches, throw size
• Heat: 6 levels from 95 to 118 F
• Timer: auto-off at 2, 4, 8 or 10 hours
• Fabric: 280 GSM flannel outside, 200 GSM sherpa inside
• Safety: ETL and FCC certified with overheating protection, per the maker

Safe use and when to ask a clinician

Mayo Clinic notes that people with any nerve damage from diabetes may not be able to sense if an electric blanket or heating pad is too hot, which can lead to burns. Its suggestion is to warm the bed with the blanket first, then turn it off or remove it before getting in.

The same caution applies to anyone with reduced feeling in the skin, or who sleeps very deeply because of medication. If that might apply, ask a clinician or pharmacist before using one.

• Do not fold or bunch the blanket while it is on, per the maker
• Do not tuck a heated blanket under a mattress or person
• Turn it off when not in use, even with a timer
• Ask a clinician first if sensation is reduced or medication causes deep sleep

Washing, storage and checks

Always unplug and detach the controller before washing. Westinghouse says its throw can be machine or hand washed in water below 86 F, then air-dried or dried on low heat.

Inspect the blanket and cord each season. Stop using it if you see scorch marks, exposed wires or a damaged controller.

When storing it for summer, fold it loosely so the wires are not creased hard, and keep the controller with the blanket so the right parts stay together. Note the model number somewhere safe in case of a recall.

• Detach the cord and controller before washing
• Follow the maker's water temperature and drying limits
• Store loosely folded, away from heavy items
• Check for scorch marks, frayed cords or a cracked controller
