Large Heating Pads: XL and XXL Sizes, Cords and Controls

A large heating pad is an electric pad bigger than the standard size, sold as king, XL or XXL. Sunbeam’s Premium XXL pad, for example, measures 20 by 24 inches, 60% larger than its standard pads, with a 9-foot cord, 4 heat settings and a 2-hour auto-off. Pick one to cover a lap or back on the couch.

How big is a large heating pad?

A large heating pad has no single standard size. Makers name their sizes, and the names do not line up between brands. Sunbeam sells electric pads in standard, king and XXL sizes. Its Premium XXL pad measures 20 by 24 inches, and Sunbeam describes it as 60% larger than its standard heating pads.

Other brands use “XL,” “extra large” or “jumbo” for sizes of their own. Read the dimensions in inches on the listing, then hold a tape measure over the spot you want to warm: your lap with a throw on top, or your back against the sofa cushions.

Large heating pad cord length and outlet reach

Cord length on a large heating pad decides where you can sit with it. A pad that covers your whole lap is no help if the cord stops short of the sofa. Sunbeam’s Premium XXL pad has a 9-foot cord, which gives you room between a wall outlet and a seat.

Measure from the outlet to the place you usually sit before you buy. Run the cord along the floor where nobody walks, and keep it out from under sofa cushions, where it can be pinched or hidden from view.

Heat settings and auto shut-off on XL pads

Heat settings and an automatic shut-off are the two controls worth comparing on any XL or XXL pad. Sunbeam’s Premium XXL pad has 4 heat settings on a push-button controller with LED lights, and it switches off after 2 hours.

More settings give you more room to run it cooler. Start low and turn it up only if you need to; if a setting feels too hot, turn it down or take the pad off. An auto-off matters most on a big pad on the couch, where it is easy to doze under a throw. The American Burn Association advises turning heating pads off before you sleep, and Sunbeam says never to sleep on one.

Using a large heating pad safely on the sofa

A large heating pad follows the same safety rules as a small one, and the bigger surface puts warmth against more of you at once. Makers, burn specialists and recall notices agree on these habits:

• Keep a thin layer of fabric between the pad and your skin, as Sunbeam advises.
• Lay the pad flat, never folded or bunched. The FDA posted a recall of Navajo Manufacturing heating pads that could overheat when folded and did not shut off.
• Switch it off before you sleep, as the American Burn Association and Sunbeam both say.
• Never use one on an infant, Sunbeam says.

Washing a large electric heating pad

Washing a large electric heating pad starts with removing the controller. Sunbeam says its Premium XXL pad is fully machine washable once the controller is disconnected, and that it is dryer-safe too. Care rules differ from model to model, so follow the label sewn into your own pad rather than another pad’s instructions. Let it dry completely before you plug the controller back in.

Large pad, heated throw or microwavable wrap?

A large heating pad suits one person who wants steady warmth across a lap or back. For other spots, a different warmer may fit better:

• To warm a whole person on the sofa, a heated throw covers more; our heated blanket guide compares throws and full-size blankets.
• For warmth without a cord, compare microwavable and electric heating pads.
• For your shoulders, a microwavable neck warmer drapes where a flat pad will not sit.
• Before you buy any wired warmer, read whether heated throws and electric blankets are safe.
