The 5 Best Extra Large Heating Pads [2021]

Extra-large heating pads come in a wide range of prices, mainly due to different features, like different heat options, multiple heat settings, and a removable cover.

Since these high-quality pads can last you for years, you may want to invest a little more in a heating pad with these special features.

Through our research, here are the top 5 large heating pads – reviewed:

1. Pure Relief  XL Heating Pad Best Value

Pure Relief Heating Pad – best price on HSN or Walmart

  • Size12″x24″ (XL) / 20″x24″ (XXL)
  • Weight – 1.45 pounds.
  • Material – microfiber (machine washable)

The Pure Relief XXL heating pad is large enough to cover large muscle groups or the entire back and no less than 6 temperature settings to choose from (with the digital LCD controller), and a moist therapy option for deeper heat penetration.

The highest heat setting is 140F, and the lowest is 105F.

The cover is soft and comfortable (machine washable) and the extra-long cord (9-foot) makes it easy to use from your bed, sofa, or chair.

The Pure Relief heating pad shuts off automatically after 2 hours, which is important if you fall asleep on it, and comes with a storage bag for easy transport.

Pure Relief Price – best price is found on Amazon for the XL size, and on HSN or Walmart for the XXL size, and a 5-year warranty!

2. Sunbeam King Size Heating Pad Fastest Heating

Sunbeam Xpressheat king size heating padCheck today’s price

  • Size – 12” X 24”
  • Weight – 1.4 pounds
  • Material – microplush

This popular electric heating pad heats in 30 seconds, has 6 heat settings (so you can pinpoint the most comfortable heat for your needs), and offers both dry or moist heat.[/su_note]

More Benefits:

  • You can see the progress as the pad heats up in the digital LCD controller
  • It offers continuous heat and an adjustable auto-off feature to keep safe.
  • Comes with a soft micro-plush cover
  • Comes with a 9 feet long power cord
  • 5-year warranty and the manufacturer has a live chat in case of any problem.

How Hot Does it Get?

The highest heat setting (6) is too hot to put next to your skin and even too hot to touch. It would require at least one layer of clothing between the pad and your body, I doubt you’ll even use it.


  • Can’t be sharply folded (though you can mold it gently to wrap around your joints), the cover is not removable.

(This can easily be solved by getting a replacement heating pad cover, like this one)

✅ Sunbeam XL Heating Pad Price – The Sunbeam large heating pad usually costs more than $30, so if you find it for less than that – it’s a good deal.

4. UTK Infrared Jade Heat Mat (XL)  Best Infrared

FDA approved UTK Infrared Jade heating padcheck today’s price on Amazon

  • Size: 31 X 21 inches, about ½ inches thick (yet this only the “medium” size. There’s a giant one that can cover your entire body)
  • Weight: 4.8 pounds, includes 126 natural jade stones.
  • Material – Jade stones, carbon fiber, PU Leather

Through my extensive research, the UTK large Infrared heating pad is the best (and safest!) large heating pad and the one I recommended to my friends.

Here’s why:

While electric heating pads are effective and not expensive, there’s still one thing that concerns me:

They all emit EMF (electromagnetic field) radiation.

For the last 2 decades, many studies have investigated the health dangers of EMF, suspecting that it can weaken the immune system, hurt brain DNA, and increase the risk of cancer.

Most studies haven’t found a direct link, but none of them were able to rule it out either.

This is especially true when you use a large electric device so close to your body, for a long time.

📢 This is why I’ve recommended an Infrared Heating pad, which emits very low to no EMF radiation at all, and uses Jade or Amethyst stones to deliver the deep penetrating infrared healing waves into your body.

Plus, compared to electric heat, infrared heat penetrates much deeper into your tissues, all the way to your nerves and spine.

This is why the UTK large heating pad is the winner in this category.

The UTK infrared heating pad penetrates 200-300 times deeper into your body without exposure to electromagnetic radiation.

More Benefits:

  • UTK heating pad contains natural jade stones to deliver deep-penetrating infrared heat
  • Relieves stress and boosts energy through negative ions therapy
  • Infrared heat makes you produce more sweat than via electric pads (helps to detox)
  • Heat is deep penetrating and effective without feeling extremely hot
  • Digital controller with auto-shutoff
  • Comfortable to lean on and you can sleep on it
  • 1-60 heat settings, 50 feels comfortable for most people
  • Flexible and can be used to wrap any part of your body
  • Built-in timer, but allows for continuous heat


  • I’ve found no cons other than the price.

The infrared heating pad is much more expensive than a regular electric one, but in my opinion, the high effectiveness and safety are worth every penny.

Like all FIR heating pads, the surface does not get hot to the touch, but the heat penetrates deep into your tissues as you lay on it for at least 30 minutes.

What is the Largest Heating Pad Available?

The largest electric heat pad would be a full-body pad, also known as a heated mattress. Our top recommendation for 2021 is the Ereada infrared heating mattresses – high-end FIR heating pads with negative ions and PEMF magnetism.

The largest size is the 32″L X 20″W one.

What is the Hottest Large Heating Pad on the Market?

The Thermophore MaxHEAT Moist Heat Pack (14″ x 27″) is the hottest XL heating pad of 2021 and can run between  150 to 165 degrees F .

Thermophore MAXHEAT – hottest large heating pad on Amazon

It is slightly weighted, with weights positioned to make it conform to your body and reduce air pockets so more heat is delivered to your body.

This is literally a steaming heating pad, that Produces intense moist heat without adding any water, and the new design comes with simple one-touch control and a 25-minute auto shut-off timer.

No surprise it is one of the most popular large heating pads on Amazon.


It wasn’t easy finding the best extra-large heating pad for my aching friend.

Some heating pads heat quickly, others take longer. Some have heat settings and some offer exact temperature control.

Some have removable covers, and some emit too much EMF.

The list goes on and on.

It’s not like there’s any quick way to compare size and features on most websites.

When I stumbled upon the hidden EMF danger in heating pads, it made me quickly search for an alternative, and that’s how I found the safest one I recommended above.

While this was a lot of work, I truly hope that it has helped my friend and it helps others in the same spot.
