10 Best Heated King Mattress Pads 2025 in the United States

The Sunbeam Restful Quilted Heated Mattress Pad for king-size beds is a solid choice if you want customizable warmth and easy care. It offers 12 heat settings, allowing you to find the right temperature for comfort. A key feature is the two separate controllers included with the king size, enabling each side of the bed to be heated independently, which is ideal for couples with different warmth preferences.

The mattress pad is made from soft 100% polyester with a cozy quilted top, providing a comfortable yet durable surface. Safety is addressed with a 12-hour auto shut-off function that helps prevent overheating or leaving it on all night by accident. It fits standard king mattresses (76" x 80"), and the pull-on style makes it easy to place and secure on your bed. It is machine washable and dryer safe, though hanging it to dry is recommended to preserve quality.

This mattress pad does not have water-resistant properties, so spills might be an issue if not cleaned promptly. Additionally, while the polyester fabric is soft, it may not feel as natural or breathable as cotton options for some users. This product is well-suited for those seeking reliable, adjustable heating with easy maintenance and safety features, particularly couples requiring different heat settings on each side of the bed.

The Sunbeam King Size Electric Heated Mattress Pad offers a comfortable and customizable heating experience, making it a good choice for those seeking warmth and convenience. With 12 heat settings and an auto shut-off feature after 12 hours, it provides safety and personalized comfort. The dual controllers allow independent heat adjustment for each side of the bed, which is great for couples with different temperature preferences.

The pad's top is made from 100% cotton, adding softness and coziness, while its water-resistant backing ensures durability and ease of mind against spills. Cleaning is hassle-free since the mattress pad is machine washable and dryer safe. At 76 x 80 inches, it fits standard king-sized beds snugly.

Despite its strengths, some users might find the control interface less intuitive, especially if they are not used to digital controllers. Additionally, while the pad has a water-resistant backing, it is not fully waterproof, so it may not completely protect against larger spills. The product is relatively lightweight at 7.42 pounds, making it easy to handle. This mattress pad is suitable for adults looking for a reliable and adjustable heating solution for their king-size bed, especially those who value independent temperature control and easy maintenance.

The Serta Waterproof Heated Mattress Pad is a well-rounded product that caters to the needs of individuals looking for a warm and comfortable bed. One of its significant strengths is the 10 heat settings, allowing users to customize their warmth levels. Additionally, the mattress pad includes dual controls for larger sizes like King, which means each side of the bed can be adjusted independently, a great feature for couples with different heating preferences.

Another key benefit is its safety features, including an auto shut off timer that can be set in 1-hour increments up to 12 hours, and ETL certification that ensures the highest safety standards are met. The pad is also waterproof, which is useful for protecting the mattress from spills and pet accidents, and it can be easily cleaned since it is machine washable. The elastic deep pockets ensure it fits mattresses up to 17 inches thick, making it suitable for most premium mattresses.

A drawback could be the need to ensure the controller is not covered while in use to prevent overheating, which might be a minor inconvenience. The material, a blend of 80% polyester and 20% cotton, is durable but may not be as breathable as other materials. The Serta Waterproof Heated Mattress Pad is suitable for anyone looking for a reliable and customizable heating solution for their bed, especially those who prioritize safety and ease of maintenance.
