How Does a Heated Mattress Pad Work? (Ultimate Guide to Safely Sleeping Warm)

Have you ever woke up in the middle of the night realizing that it’s freezing cold in your bedroom? And that even your heavy blanket isn’t enough to keep you warm.

A heated mattress pad is a great way to keep your body nice and warm when the temperature drops—but how do they work?

Let’s talk about it.

How does a heated mattress pad work?

Heated mattress pads generally have insulation-coated wires sewn underneath additional layers of plastic and fabric. These wires are then connected to a power supply that passes a current through them, generating heat. They have multiple heat settings, including timers that will turn off the heating at a set time or according to a schedule.

There are a ton of things to consider when deciding whether to buy a heated mattress pad. This article is geared toward helping you understand how mattress heating pads work. It will give you the information you need to decide if a heated mattress pad is right for you.

What’s inside a heated mattress pad?

Generally speaking, if you were to cut open a heated mattress pad and look at its insides, you would find basically the same thing throughout all heating pads.

In fact, heated mattress pads look like any other regular mattress pad, at least on the outside.

However, heated mattress pads work by heating wires that are embedded through the insides of a heated mattress pad.

Inside a general heating mattress pad, you’ll find electrical wiring laid down in a pattern that doesn’t overlap each other. The pattern places as many of the wires as possible throughout the surface area of the pad so that heating of the pad is evenly spread throughout. 

It’s similar to that apple-eating snake game where you’ve advanced so far and the snake is so long now. Since the rule is that the snake can’t touch itself or it will die, you get this pattern of the snake’s body neatly covering all of the playing field.

This pattern is then covered and sealed by a plastic material that has a high capacity for heat. This allows the plastic to keep the heat from dissipating and protects the user from getting burned.

Fortunately, the electricity that runs through these wires is regulated by a temperature sensor and the control panel. This enables the panel to closely monitor and regulate the temperature, otherwise adding extra protection from overheating or underperforming.

Are heated mattress pads good or bad for you?

Heated mattress pads can have both positive and negative effects on your health, depending on how they are used. Some potential benefits of using a heated mattress pad include:

  • Improved sleep: A heated mattress pad can help you sleep more comfortably by keeping you warm on cold nights, which can help you fall asleep faster and stay asleep longer.
  • Relief from joint and back pain: The heat from a heated mattress pad can help to relieve pain and soreness in muscles and joints, making it a good choice for people with arthritis or other chronic pain conditions.
  • Promotes relaxation: The warmth of a heated mattress pad can promote relaxation and help you unwind after a long day, which may contribute to better sleep and overall well-being.
  • Relaxes the muscles: The heat from a heated mattress pad can also help to relax tense or tight muscles, which can reduce discomfort and improve mobility.

There are, however, some possible risks to using a heated mattress pad, such as:

  • Burns to the skin: If a heated mattress pad is used improperly or left on for too long, it can overheat and cause burns or other injuries. Always follow the manufacturer’s instructions and use safety features like automatic shut-off.
    Electric shock: There is a risk of electrical shock or other hazards associated with using an electric heating pad. It is important to choose a model that is properly certified and to use it only as directed.
  • House fires: In rare cases, a heated mattress pad can cause a house fire if it is left on for too long or used improperly. Be sure to follow safety guidelines and always turn off the pad when you are not using it.

What are the benefits of using a heated mattress pad?

  • Improved sleep: One of the most significant benefits of using a heated mattress pad is that it can help improve your sleep quality. The heat can soothe your muscles and help you relax, leading to a more restful sleep.
  • Pain relief: If you suffer from muscle or joint pain, a heated mattress pad can provide relief. The heat can help ease soreness and stiffness, and increase blood flow to the affected area, reducing pain and inflammation.
  • Energy savings: If you use a heated mattress pad, you may be able to turn down the heat in your home at night, which can lead to energy savings and a lower utility bill.
  • Customizable temperature: Many heated mattress pads come with temperature controls that allow you to set the temperature to your liking. This can help you find the perfect temperature for your needs and preferences.
  • Convenience: A heated mattress pad is easy to use and maintain. It can be turned on and off with the touch of a button, and most models can be machine-washed and dried.
  • Allergy relief: Contrary to believe, heating the air actually does lower humidity. A heated mattress pad may provide allergy relief because the heat can reduce humidity in the bed, which can create an environment that is less hospitable to dust mites and other allergens.

What to consider when choosing a heated mattress pad

  • Size: The first thing to consider is the size of your mattress. Make sure to choose a heated mattress pad that fits your bed properly.
  • Material: Consider the material of the mattress pad. Look for one that is soft, comfortable, and durable. Some common materials include cotton, polyester, and blends of the two.
  • Heating settings: Look for a mattress pad with multiple heating settings so that you can adjust the temperature to your liking. Some models even have dual heating zones, so you and your partner can customize your sides of the bed.
  • Safety features: Safety should be a top priority when using a heated mattress pad. Look for models with safety features like automatic shut-off, overheat protection, and UL certification.
  • Maintenance: Consider the ease of maintenance. Look for a mattress pad that is machine-washable and easy to clean.
  • Price: Finally, consider the price of the mattress pad. While a higher price tag may indicate better quality, it’s important to find a model that fits your budget without sacrificing safety or comfort.
  • Ease of use: Look for a mattress pad that is easy to use and has intuitive controls. Ideally, the pad should be easy to install and operate.

Are heated mattress pads safe?

Generally yes. As long as you’ve purchased a heated mattress pad from a well-known company that doesn’t cut corners on the build and manufacturing of these things, then you should be safe.

The that are properly used to make these pads must have some sort of electrical insulation. Not only are the metal wires suppose to be fully wrapped around an insulated plastic coating, but the entire mesh lines of wires should be contained in a plastic or fabric that’s insulated as well.

I recommend looking for heated mattress pads that traditionally have a high reputation in the industry.

Here are a few tips to ensure you aren’t harmed by any malfunctions of a heated mattress pad.

  • Make sure to inspect the pad regularly – From time to time, look around the pad. Look for any breakage or holes that may expose the insides of the pad. If you do find any, you’ll need to buy a new one.
  • Only use it when you need it – If the room is cold and you can’t sleep because of this, then this would be a good reason to turn it on. If you don’t need it, just keep it off.
  • Find one that fits your bed – Don’t buy a twin-sized pad for a queen and don’t buy a queen-sized pad for a twin. Make sure it covers your entire bed.
  • Don’t let your children use it unsupervised – These are electrical items and you should be very careful when leaving children alone with them. Toddlers may nibble on it while older kids may try to swing it around and possibly damage it.
  • Don’t try to repair it – After it’s been damaged, the deal is done. Attempting to repair it may put you at risk if it is repaired improperly. You don’t want to wake up to a fire. Play it safe and replace it.

How do I safely install a heated mattress pad?

  1. Unpack the pad: Remove the heated mattress pad from its packaging and lay it flat on your bed.
  2. Position the pad: Position the pad so that the heating elements are facing upwards and the cords are located near the foot of the bed.
  3. Attach the pad: Secure the pad to your mattress using the straps or elastic bands provided. Make sure that the pad is flat and smooth.
  4. Connect the cords: Connect the cords from the pad to the control unit, following the manufacturer’s instructions. The control unit should be placed on a nearby bedside table or other convenient location.
  5. Plug it in: Plug the control unit into a nearby electrical outlet and turn it on. Adjust the temperature to your desired level using the controls.
  6. Test it out: Before using the heated mattress pad for the first time, test it out for a short period of time to make sure that it is working properly.

Can you put a waterproof mattress pad over a heated mattress pad?

This is potentially a hazard.

Unsurprisingly most heated mattress pads are well designed with materials to protect themselves from spills, germs, and bugs.

Putting a heated mattress pad underneath a mattress protector may block the transition of heat. This may indirectly have you crank up the heat further so that heat can penetrate through the protector and thus overwork the heating pad.

I would recommend that you keep the heated mattress pad on top of the protector. If something were to happen to the heated pad, you wouldn’t have to wake up and quickly try to remove the heated pad from underneath the protector.

If you can, purchase a thin protective mattress encasement. Sometimes it comes with a heated pad.

What are the different settings on a heated mattress pad?

Temperature SettingTemperature Range (°F)Temperature Range (°C)
Low75-80°F24°C to 27°C
Medium80-85°F27°C to 29°C
High85-90°F29°C to 32°C
This table gives the rough estimate temperature that you’ll find at different levels of heat featured on most heated mattress pads
  • Low: This setting is typically around 75-80 degrees Fahrenheit (24°C to 27°C) and provides a mild amount of warmth. It is good for people who want a little extra warmth but do not need a lot of heat.
  • Medium: This setting is typically around 80-85 degrees Fahrenheit (27°C to 29°C) and provides a moderate amount of warmth. It is a good option for people who want more warmth than the low setting provides but do not want to be too hot.
  • High: This setting is typically around 85-90 degrees Fahrenheit (29°C to 32°C) and provides the most warmth. It is a good option for people who are very sensitive to cold or who want a lot of heat.

Can you leave a heated mattress pad on all night?

It’s not recommended to have heated mattress pads stay on for long periods of time. They are meant to promote sleep and shut off after a fixed amount of time. Most heating pads will even last a default and maximum time limit of 10 hours.

This is a length of time the manufacturer uses to avoid the mattress pad from malfunctioning.

However, a typical modern mattress pad is unlikely to cause any issues if there are nights when it is much needed.

How long does it take for a heated mattress pad to heat up?

It’s been recorded that heated mattress pads take approximately 10 minutes or less to fully get to the desired temperature.

Do heated mattress pads use a lot of electricity?

While owning a heated mattress pad does add on an extra electrical device to the home. It doesn’t affect your electric bill quite as much as you think.

Take into consideration the indirect results of owning a heated mattress pad. If the room is always cold, the average person might turn up the heater overnight.

If that person had actually owned a heated mattress pad, they might not need to do so. As a result, this would be much more efficient than running the heater all night.

Is a heated mattress pad safe for children?

A heated mattress pad can be safe for children as long as appropriate safety measures are taken.

Most of the time, you shouldn’t use it on a child younger than 5 years old because they might not be able to tell you if they are uncomfortable or if they are getting too hot.

You should choose a pad that lets you set the temperature to a safe level for your child, watch them use it, and check the pad’s temperature every so often to make sure it is not too hot.

Look for a pad that has safety features like automatic shut-off or timers.

Our best recommendation is to avoid using heated mattress pads for any child and try to find an alternative to keeping him or her warm at night.

How do I know what size heated mattress pad I need?

To determine the size of heated mattress pad you need, you will need to measure your mattress.

Most heated mattress pads are available in standard mattress sizes such as twin, full, queen, king, and California king. Be sure to measure both the width and length of your mattress to ensure that you choose the correct size.

What materials are heated mattress pads made of?

Heated mattress pads can be made of a variety of materials, including cotton, polyester, microfiber, and blends of these materials.

The heating elements are typically made of thin wires that are woven into the fabric of the pad.

How long do heated mattress pads last?

How long a heated mattress pad lasts depends on how well it is made and how well it is taken care of. On average, a good-quality heated mattress pad can last for 2 to 3 years with proper care.

Are heated mattress pads waterproof?

Not all heated mattress pads are waterproof, but some are designed to be water-resistant or have a waterproof layer to protect the heating elements.

If you are concerned about spills or accidents, look for a heated mattress pad with waterproof features.

How do you clean your heated mattress pads?

The cleaning instructions for a heated mattress pad will depend on the specific product, but many can be spot cleaned with a damp cloth or machine washed on a gentle cycle.

However, keep in mind that not all heated mattress pads can be placed in the washing machine.

Be sure to consult the manufacturer’s instructions before cleaning your heated mattress

Can you wash heated mattress pads in the washing machine?

Some heated mattress pads can be washed in the washing machine, but it is important to follow the manufacturer’s instructions.

In general, you should use a gentle cycle and a mild detergent and avoid using bleach or fabric softeners. Some heated mattress pads may need to be hand-washed or spot cleaned instead.

Do heated mattress pads use a lot of electricity?

The amount of electricity used by a heated mattress pad will depend on the specific product and how often it is used.

However, in general, heated mattress pads are designed to be energy-efficient and use less electricity than other heating devices like space heaters or electric blankets.

Are there heated pillows?

Yes, there are heated pillows available on the market. Most of the time, these pillows have small heating elements that can be turned on to warm and comfort you.

Be sure to use heated pillows safely and according to the manufacturer’s instructions to avoid any risk of burns or other injuries.

Heated mattress pads vs. electric blankets

Heated mattress pads and electric blankets both provide warmth and can be used to help you sleep comfortably in cooler temperatures.

However, there are some differences between the two.

Heated mattress pads are placed on top of the mattress and secured with elastic straps or a fitted sheet, while electric blankets are draped over the top of the bed like a regular blanket.

Heated mattress pads are designed to heat your body from beneath, while electric blankets heat you from above.

Also, heated mattress pads may be more energy-efficient than electric blankets because they are heating a smaller space.

Should I buy a heating blanket or a heated mattress pad?

Heated mattress pads lay underneath the person, who is underneath a blanket. What that results in is the heat being well insulated within the confines of the bed and normal blanket.

For this reason, the advantage goes to the mattress pad over the heating blanket.

Since heat expands and rises, a heating blanket’s generated heat would dissipate. Without any further insulation from another blanket above it, the heat ends up getting lost to the room, warming it up. This is not as efficient compared to the heated mattress pad.
