What is a Heated Mattress Pad Made From?

Multiple components make up a heated mattress pad, and here is a little information that one needs to know about each of them:

— Cover

Every heated mattress pad is covered with a certain type of fabric. Cotton is a very common choice here, especially since it’s a soft material with high capabilities of absorbing moisture. Another choice would be polyester, which doesn’t absorb moisture as cotton does, but does offer a certain level of breathability and is less expensive. You are also likely to find mattress pads with covers that are made from a blend of polyester and cotton.

— Heating element

This lies at the core of the mattress pad and will heat the entire thing to the level that you set up yourself. The heating element is made from a bunch of small wires that traverse the pad. When you own a mattress pad with thin wires, you are also likely to feel the wires inside the pad. The layout of the wires can also tell you whether or not a mattress pad is evenly heated. You want to make sure that the wires have a few inches of spacing between them. Depending on the mattress pad model you choose, the wires can be replaced with tubes that carry hot water.

— Controller

The controller of a mattress pad is a small panel that grants you access to the settings of the heater. For the most part, heated mattress pads come with wired controllers, but some newer and more expensive models have wireless remote controls. If you buy a larger heated pad with two heating zones (one for each side of the bed), it will most likely come with two controllers.

— Skirt

This is a component of the mattress pad that goes around the corners and the sides of the bed and helps keep the mattress pad in place. The skirt is usually made from polyester fabric because it’s very stretchable.

Features to Look Out For

Finding a heated mattress pad that suits your needs means understanding what are the different features that such a product comes with and knowing which of these are most important to you. Amongst those features, we’d like to mention:

• Heat settings

You will discover that heated mattress pads will allow you to change the level of the heat output to a number that usually varies between one and 10. Not all mattress pads with a heating option have 10 levels of heat to offer, and some of them are more basic and have fewer levels.

• Pre-heating

Certain mattress pads have a feature that allows them to heat up even before you get the chance to get into bed. This will have the bed all warm and toasty so that you can benefit from that heat the second you jump into bed.

• Dual-heating

This feature is usually found on larger mattress pads and it means that each side of the bed has its wiring system, for individual heat adjustment. This feature is really useful for couples that share a bed and have different preferences when it comes to heat settings. Take note that this feature is usually found only in pads that are Queen size or larger.

• Heating & cooling

When you’re scouting the market looking for a heated mattress pad, you are bound to come across models that also offer a cooling feature. These can be extremely useful to sleepers who are cold during the winter but sleep hot during the summer. Great for night sweats.

• Timers

A timer on a heated mattress pad does pretty much what you would expect it to do: it turns off the heating system when the timer expires. You choose a period (8 hours, for example) and, when that time is up, the heated pad will automatically turn itself off. This is both a useful safety measure, as well as a way to conserve energy that would otherwise be spent heating the pad the entire night.

Is It Safe to Use a Heated Mattress Pad?

It is perfectly normal for you to wonder if it’s okay to sleep on something that has wires and is connected to a power outlet. To make sure that you stay as safe as possible, here are the features that you want your electric mattress pad to have:

  • The auto-shutdown feature shouldn’t be negotiable when it comes to a product that’s constantly plugged in while you’re sleeping. This will prevent the pad from staying on throughout the entire night.
  • UL certification is the label you want to look out for. Specifically, you want to look out for products that meet UL 964 standards because they apply to heated bedding. When you spot heated mattress pads with this certification, it means the product has been tested by an independent organization.
  • Overheating protection is another important feature. It is a system that identifies when the pad has exceeded the normal temperature threshold and will shut the entire thing down to prevent further incidents.

Best King-Size Heated Mattress Pads

Let’s move on by looking at some of the best heated-mattress pads that money can buy for all those of you looking for a King-sized solution to regulate temperature while you’re sleeping.

1. Editor’s Choice: Chili Technology chiliPAD Cube 3.0

SPECS:

  • Available sizes: Twin XL, Queen, King, Cal King
  • Material: polyester & polyester blend
  • Number of heat settings: temperature range between 55 and 115 degrees Fahrenheit

Ever since the chiliPAD was first launched, people were divided into two categories: those who love and those who hate this product. There is nothing in between. We fall into the first category (otherwise we wouldn’t have included it in this list), so we wanted to talk about what it has to offer because it is one of the most expensive heated mattress pads you’ll ever come across. The chiliPAD is a mattress pad with both heating and cooling capabilities, which grants the sleepers a lot of control over their bedding temperature. 

It has a water-based system with hoses that run through the pad itself, circulating hot or cold water through the tubes. The temperature range itself is pretty wide: from 55 to 115 degrees Fahrenheit. What you get is a mattress pad connected to a cube that can be placed underneath the bed so you never have to worry about tripping over it. It has a wireless remote control that allows you to change the settings as needed.

ProsCons
  • Heating & cooling features.
  • Wireless remote control operation.
  • Wide temperature range.
  • Dual-sided heating option.
  • Very expensive.

Who Should Buy This? 

The chiliPAD is the perfect product for people who want a premium solution for temperature regulation, for those of you that share a bed with someone with different temperature preferences, and for those of you that would like to see the best and newest technology embedded in a heating and cooling mattress pad

  • Material: cotton
  • Number of heat settings: 20

Made with a comfortable cotton cover and heating options that are bound to leave you pleased with the money you spent, the Beautyrest heated mattress pad is the kind of product that you want to look out for. There are 20 different heat settings to choose from, so you have a lot of room to adjust the pad to the temperature that you’re most comfortable with. The cotton cover features a 250 thread count, so it’s a worthy product.

 Each of the sides of the bed can be controlled via the included remote controls, so if you and your sleeping partner have different temperature preferences, then you have to check this product out. It is also UL certified, so you can rest assured that you’re using a product that’s been tested and is safe to use. The Kind-sized version comes with a 15-inch deep pocket that allows you to secure the pad on mattresses up to 18 inches in height.

ProsCons
  • Comfortable cotton cover.

3. Best Budget: Electrowarmth M76Fld Mattress Pad

SPECS:

  • Available sizes: Twin, Long, Queen, King, Olympic Queen, Short Queen, Double
  • Material: polyester & polyester blend
  • Number of heat settings: 10

Next up, we wanted to show you a heated mattress pad that’s more affordable compared to the other two options we went through today. It is a mattress pad that’s made with polyester and polyester blend, which is certainly something that helps lower the price of the end product. You have a lot of size options to choose from and most of those that are available come with a single or a dual heat setting, meaning that each side of the bed is controlled separately. 

The version that we propose is a King-sized pad with different controls for each side of the bed so that you and your sleeping partner can choose from the 10 available heat settings, depending on what you need to achieve thermal comfort. It has an overheating protection system, can be cleaned inside the washing machine, and can memorize the last heat setting you selected and pick it every time you turn the pad back on.

ProsCons
  • Multiple size options.
  • Machine-washable.
  • Overheating protection.
  • Good price.
  • Slippery surface.

Who Should Buy This? 

The Electrowarmth M76Fld mattress pad is for those of you that share a bed with a partner with different temperature preferences and makes a worthy purchase for those of you looking for a more affordable heated pad.

4. Best Fleece: MERRY HOME Mattress Pad 

SPECS:

  • Available sizes: Twin, Full, Queen, King
  • Material: fleece & foam
  • Number of heat settings:  from 50 to 149 degrees Fahrenheit

The Merry Home mattress pad is a little different compared to the other models we’ve shown you so far, so let’s start with the really interesting characteristics. First of all, let’s talk about the double-layer fleece fabric that’s used to make the cover. Fleece is the kind of fiber that you love to feel in the winter because it traps heat so well and leaves your body warm. Inside the pad, you have a whole-piece foam that offers cushioning and comfort. 

The control unit of the pad is a device pretty similar to that of the chillPad’s cube, but with a more modern design. It offers precise temperature control and grants you the power to adjust the temperature of the pad by choosing one in the interval between 50 and 149 degrees Fahrenheit. The integrated timer can also be adjusted between one and 24 hours, so you get to choose when the pad turns itself off. It comes with a 14-inch deep pocket that helps secure the pad to the mattress.

ProsCons
  • Touchscreen control unit.
  • More heat settings.
  • Deep-pocketed pad.
  • Integrated timer.
  • Poorly-written manual.

Who Should Buy This? 

The Merry Home heated pad is designed for sleepers that don’t just want to choose between several heat settings but would rather prefer the freedom of inputting the desired temperature themselves.

5. Best Water Heated: JML Mattress Pad

SPECS:

  • Available sizes: Twin, Queen, King
  • Material: fleece & cotton
  • Number of heat settings: 86 to 140 degrees Fahrenheit

Heated mattress pads that circulated hot water through the tubes can be just as efficient, if not more efficient than their completely electrical counterparts. Such is the case of the JML pad, a product designed to use the power of water to heat the entire surface of the bed and help you sleep in a warm and cozy environment. The JML mattress pad shares a lot of similarities with the chiliPAD but it’s available at a much lower cost. 

The pad is designed with multiple layers that help insulate the tubes while making sure that the heat is still dispersed from top to cotton. It has a fleece sponge composite surface, a superelastic cotton filling that is super elastic, and an anti-slip reverse side. You can set the temperature at a mark between 86 and 140 degrees Fahrenheit. The system integrates a shutdown timer that you can set at one-hour increments, between one and 12 hours.

ProsCons
  • Noise reduction system.
  • Integrated timer.
  • Remote control operation.
  • Good price for the technology.
  • No dual-sided heating option.

Who Should Buy This? 

The JMP heated mattress pad is an option worth considering if you’d like a more basic version of the chiliPAD, but still a product that delivers according to one’s expectations.

Bottom Line 

When you’re looking to invest in a heated mattress pad, there’s not that much information that you need to know beforehand. It might be more difficult to research everything you need to know before purchasing a pillow rather than a heated pad. With these products, you’re most interested in products that are certified so you know they’re safe to use. The rest is a matter of prioritizing what you need from a heated pad. 

For instance, if you share a bed with a partner that has a different temperature preference, you surely want to opt for a product with a separate heating system on the other side of the bed, meaning that each of you gets to control the temperature on their side of the bed. You also want to check out details such as warranty, return policies, and probably power consumption, if you’re interested in a product that doesn’t consume a lot of electricity.
