About 4.5 million electric blankets and electric mattress pads are sold in the United States every year. What's more, about 25 million to 30 million electric bed warmers are already in use. You can also find electric body pillows to snuggle up against at night, but they are a much smaller share of the market.
Some people have the patience to crawl into a cold bed and wait for the bedding to gradually warm. Others, however, need immediate warm-bed gratification. To the rescue are heated blankets and electric mattress pads, ones that heat quickly and even preheat, so a body never has to come into contact with cold sheets.
A FACTUAL COMPLETE AND UNBIASED CONSUMER GUIDE
If you turn your thermostat down at night to save money, sliding into bed can be a very chilly proposition. Heated mattress pads warm up your bedding from underneath and are a great alternative to electric blankets — particularly if you prefer to use a comforter as your top layer. The Textiles Lab at the Good Housekeeping Research Institute evaluated three electric mattress pads to see which will keep you warm. All of the pads we tested come with dual controls on their queen or king sizes, so there's never any argument over "too hot" or "too cold." Plus, these are energy efficient — even the biggest electricity user was quite low (just 7 cents per night, or $2.10 per month). (Prefer electric blankets? .)
Importantly, electric mattress pads also provide additional benefits i.e. medicinal. For people suffering from muscle cramps, body pains, or arthritis, the use of a heated pad can help ease these problems allowing you to relax and enjoy a good night’s sleep.
