Which should you buy?
Neither one wins outright. Decide by your mattress first, then by how you like to get warm.
Choose a heated mattress pad if
- You want the bed warm before you get in
- You and a partner run at different temperatures (look for dual zones)
- You would rather lie on the heat, and your mattress is not memory foam
Choose a heated blanket if
- Your mattress is memory foam
- You would rather have the heat over you than under you
- You also want warmth on the couch: a heated throw is made for it
The same safety rules apply to both: read them before you buy.

From makers' manuals and listings, Sleep Foundation, UL and the DOE; we don't lab-test. How we pick
Heated blanket vs heated mattress pad in eight rounds
One round each goes to the pad and the blanket; the other six are even, or the sources don't settle them. Open a round for the detail.
1. Where the heat comes from
Above you vs under the sheetDifferent jobs
A blanket warms you from above. A pad heats from below, so it warms what touches the mattress: the sheet, and you (Sleep Foundation). Sleep Foundation notes a blanket can go around you on the sofa, but Sunbeam's manual says not to tuck any heated bedding into a sofa or other furniture, and not to use a throw with a recliner, a rocking chair or a chair on casters.
2. Overnight auto-off
10 hours on both, in the models we checkedTie
On Sunbeam models with auto-off, blankets and mattress pads switch off after 10 hours and throws after 3. Some Sunbeam controls have an Auto-Off Select button that can turn the timer off, so check that it is on. Beautyrest lists 10 hours for both its Plush blanket and its Deep Pocket pad.
3. Couples and dual controls
Both offer them in bigger sizesTie
Sunbeam's dual-control models run each side of the bed on its own control. Beautyrest's blanket comes with two controllers in Queen and King, and its pad has two zones in Queen, King and California King; the smaller sizes have one.
4. Preheating the bed
The pad's heat stays under youEdge: pad
Selected Sunbeam blankets and pads alike have a 30-minute preheat, and UL's advice for electric blankets is to warm the bed, then switch off before you sleep. The edge to the pad is our own reasoning, not a source's: its heat stays under the sheet you lie on.
5. Washing
Same maker method once the cord is offTie
Sunbeam's manual gives one method for blankets, mattress pads and throws: unplug, detach the cord, presoak 15 minutes in cold water with mild soap, wash on gentle and cold for two minutes, then 10 minutes on low and drape to air-dry. A cord or control never goes in water (Sunbeam).
Sleep Foundation is more cautious: it does not generally recommend machine-washing an electric blanket, and says one with a detachable cord may be machine washable if its care label allows. Some pads are spot-clean only. Full steps: how to wash a heated blanket without damaging the wiring.
6. Energy use
No verified pad wattage to compareNo verdict
The US Department of Energy, cited by Consumer Reports, puts a typical full-size electric blanket at about 100 watts. Sleep Foundation gives 40 to 60 watts on medium, and 100 to 200 watts for larger dual-zone models. We found no verified wattage for heated mattress pads, so we don't guess; the rating label will tell you.
7. Memory-foam mattresses
A pad's heat softens the foamEdge: blanket
Sleep Foundation calls a heated mattress pad on memory foam generally not recommended, because the heat softens the foam and can leave impressions. A blanket goes on top instead, as long as you don't lie on it: Sleep Foundation warns against lying on an electric blanket, particularly on foam mattresses, which trap heat.
8. Beds to avoid and safety habits
The same rules apply to bothSame rules
Neither one goes on a waterbed, a bunk bed or a mechanically adjustable bed, Sunbeam's manual says, and UL adds sofa beds and pull-out beds. Sleep Foundation calls electric blankets unsuitable for waterbeds and some adjustable beds. The habits are shared too: see safety for both.
Safety notes that apply to both
None of the sources we read shows either one is the safer choice. They give both the same rules.
- Never use the two together: Sunbeam says not to use another electronic heating device with its heated bedding.
- Not on a waterbed, a bunk bed or a mechanically adjustable bed (Sunbeam); UL adds sofa beds and pull-out beds.
- Don't fold, tuck or bunch it while it is on, and put nothing on top of a blanket while it is on (CPSC, UL).
- Check for worn spots, loose plugs and dark or charred patches; throw out one that is damaged (CPSC, UL).
- Buy one listed by a recognized lab such as UL, never secondhand, and store it rolled, not folded (UL).
Sunbeam's own warning: its heated bedding is not for an infant, a child, an incapacitated or immobile person, a diabetic, anyone insensitive to heat, or anyone who cannot understand the instructions or operate the controls. Read the one in your model's manual.
Before you buy, look the model up in CPSC's recalls and warnings: CPSC has told consumers to stop using Melinora heated blankets.
Heated blanket vs mattress pad: questions
Is a heated mattress pad better than an electric blanket?
Neither is better overall. A pad warms the bed from below and is the natural way to pre-warm it; a blanket warms from above and suits memory-foam mattresses better, because a pad's heat softens the foam. Neither goes on a waterbed or a mechanically adjustable bed.
Can you use a heated blanket and a heated mattress pad together?
No. Sunbeam's manual says not to use another electronic heating device with its heated bedding, and that includes a heated blanket on top of a heated pad.
Which uses more electricity, a heated blanket or a heated mattress pad?
The US Department of Energy, cited by Consumer Reports, puts a typical full-size electric blanket at about 100 watts, and Sleep Foundation gives 40 to 60 watts on medium. We found no verified figure for heated mattress pads, so we cannot say which uses more; check the rating label of the model you are looking at.
Can you put a heated mattress pad on a memory foam mattress?
Sleep Foundation says it is generally not recommended, because the heat softens memory foam and can make it more prone to impressions. A blanket on top is the usual alternative; don't lie on it, which Sleep Foundation warns against, particularly on foam.
Can you use a heated blanket or mattress pad on an adjustable bed or a waterbed?
No. Sunbeam's manual says not to use its blankets or mattress pads on a waterbed, a bunk bed or a mechanically adjustable bed, and UL adds sofa beds and pull-out beds. Sleep Foundation calls electric blankets unsuitable for waterbeds and some adjustable beds.
Do heated blankets and heated mattress pads turn off on their own?
The models we checked have a timer. On Sunbeam models with auto-off, blankets and mattress pads switch off after 10 hours and throws after 3, though some controls let you turn the timer off. Beautyrest lists 10 hours for its Plush blanket and its Deep Pocket pad. Check that auto-off is on for the model you buy.
Can you wash a heated mattress pad the same way as a blanket?
For Sunbeam, yes: its manual gives the same steps for blankets, mattress pads and throws once the cord is detached. Some pads are spot-clean only, so read the care label first.
Which is better for couples?
Both come with dual controls in bigger sizes. Sunbeam's dual models run each side on its own control; Beautyrest's blanket has two controllers on Queen and King, and its pad has two zones on Queen, King and California King.
