Are Heated Throws and Electric Blankets Safe?

Yes, a modern heated throw or electric blanket is generally safe for an adult who follows the manual. The risks come from age, damage and misuse: folding or bunching it while on, trapping the cord, or using one on a baby, a child or someone who cannot feel heat. Replace any blanket more than ten years old.

What makes an electric blanket unsafe?

Most problems trace back to four things, in roughly this order of importance.

1. Age and wear. Electrical Safety First, a UK charity, lists ten years as the point to replace a blanket regardless of how it looks.
2. Heat trapped in folds. Sunbeam’s manual warns that folding or bunching a heated product while it is on can cause excessive heating.
3. Damaged or pinched cords. Cords trapped under a mattress, between bed slats or in sofa cushions can be crushed.
4. Faulty products. Recalls happen. In March 2023, the CPSC announced a recall of about 43,000 Sunbeam heated blankets distributed by Star Elite because they could overheat. In July 2026, it warned consumers to stop using Melinora heated blankets sold on Amazon, after reports that the internal wires could melt through the fabric.

Signs your heated throw needs replacing

Electrical Safety First says to replace an electric blanket if any of these apply:

• It is more than ten years old.
• The fabric is worn or frayed.
• There are scorch marks or discoloration.
• Wires are visible or poking through the fabric.
• The cord between the plug and control, or between the control and blanket, is damaged.
• The control buzzes or gives off a smell.
• The connector on the blanket is damaged or overheating.

Who should not use a heated throw?

Sunbeam’s heated bedding manual lists people who should not use its heated products:

• an infant or a child
• an incapacitated or immobile person
• a person with paraplegia or quadriplegia
• a person with diabetes
• anyone insensitive to heat, such as a person with poor circulation
• anyone who cannot understand the instructions or operate the controls

The common thread is the ability to notice heat and switch the blanket off. If you are unsure whether a health condition affects that, ask your doctor before buying one.

How to use a heated throw safely

These rules come from Sunbeam’s manual and Electrical Safety First.

On the sofa

Lay the throw flat over you rather than wrapping it in tight folds. Sunbeam says not to tuck in, pinch or flex the wired heating area. Keep the cord and controller visible, not pushed into sofa cushions.

In bed

Electrical Safety First suggests unplugging an electric blanket when you get into bed. If you want to keep it on overnight, it should have temperature controls, automatic shut-off and overheat protection. Heated throws are a different product: Sunbeam’s throws switch off after 3 hours, while its blankets and mattress pads run up to 10 hours.

Keep cords where they cannot be pinched, not trapped between the mattress and bed frame. Do not add a hot water bottle; our hot water bottle guide covers that option on its own.

Around water and pets

Never touch the blanket with wet hands or feet, and dry off fully after a bath or shower. Keep pets off it, since they can damage the wiring. Do not use pins, which can pierce the wires.

Washing and storage

Unplug it first. Sunbeam’s manual says to machine wash cold on a gentle cycle, or hand wash, then tumble dry low on a delicate cycle, and never use a laundromat dryer. Electrical Safety First adds: fold it loosely, store it somewhere cool and dry, keep heavy items off it and skip moth-proofing chemicals.

What to check before buying one

The safety standard. In the U.S., UL 964 is the safety standard for electrically heated bedding. Its scope explicitly includes throw blankets, blankets, mattress pads and foot warmers on standard 120-volt household power. Look for a certification mark from a recognized testing lab on the label or listing.

Auto shut-off and heat settings. A timer is a basic safeguard. Several settings let you run it cooler.

A detachable controller. You need to remove it to wash the throw.

Buy new. Age and hidden damage are the main risks, and a secondhand blanket’s history is unknown.

Alternatives if you would rather skip the wiring

A thick sherpa or faux fur throw traps a lot of warmth with no power at all. A weighted blanket adds pressure rather than heat, and our flannel sheets guide covers brushed-cotton bedding for cold nights. See every option in our throw blanket buying guide.
