10 Best Cooling Mattress Toppers 2026 in the United States

The Viscose Made from Bamboo Twin Mattress Topper by Niagara Sleep Solution offers several appealing features. It is made from a blend of 60% polyester and 40% bamboo viscose, which makes it ultra-soft and gentle on sensitive skin. The topper is quite thick and designed to fit mattresses ranging from 8 to 20 inches deep, allowing for versatility in use. One of its standout features is its cooling properties, attributed to its breathable and sweat-absorbent nature, which could be beneficial for those who sleep hot.

The topper is designed to provide an extra cushion, potentially easing back pain, which could be a significant plus for those with back issues. Additionally, it boasts a deep pocket with stretchy sides, making it easy to put on and secure on thick mattresses. It is also machine-washable, adding to its convenience for regular maintenance.

While its softness and breathability are strengths, the actual firmness level is not explicitly mentioned, which could be a consideration for those seeking a certain level of support. The mix of materials may not be as durable as some other options, and while it is marketed as being free of chemicals like latex or formaldehyde, it may not be suitable for those with severe allergies to other synthetic materials. This mattress topper seems best suited for adults looking for an affordable way to enhance the comfort and cooling of their existing mattress, particularly those experiencing mild back pain.

This Ultra Soft King Size Mattress Topper is designed with comfort in mind, using a blend of bamboo viscose and polyester that feels gentle and smooth on the skin. The bamboo fabric naturally helps keep sleepers cool and absorbs sweat, which is great for those who often feel hot at night. It’s quite soft, adding a plush, cloud-like layer to your mattress that might also ease back pain by providing extra cushioning. The topper fits mattresses from 8 to 20 inches deep thanks to its stretchy deep pockets, making it easy to put on and less likely to slip off during the night. It’s also machine washable, which is a big plus for keeping things fresh.

The topper is on the softer side, so it may not suit those who prefer firmer support. Since it’s relatively lightweight, it might not feel very thick or durable over many years, especially if you want a topper that lasts through heavy use. If you want a soft, breathable mattress topper that helps with heat and offers gentle cushioning, this is a solid choice, but those needing firmer support or heavy-duty durability might want to explore other options.

The Linenspa 3 Inch Gel Swirl Memory Foam Mattress Topper is designed to add comfort and cooling to your existing mattress. Made from memory foam infused with cooling gel, it helps distribute heat away from your body, making it a good choice for those who tend to overheat at night. With a thickness of 3 inches, it offers a medium firmness that balances softness and support. This makes it suitable for users looking to soften a firm mattress or relieve pressure points without sinking too deeply.

Durability is decent since the topper is CertiPUR-US certified, which means it meets safety and quality standards and should last with proper care. It is not water-resistant, so spills could damage it, and it does not specifically mention allergen resistance. The topper is easy to set up, expanding fully within a day or two after unpacking, and it comes with a 3-year warranty for peace of mind.

This mattress topper provides a cooler sleep experience thanks to the gel infusion and offers medium firmness, which may not satisfy those wanting a very firm or very soft feel. Because it is not waterproof or explicitly hypoallergenic, individuals with specific sensitivities might need to take extra precautions. It is suitable for most adults looking to improve comfort and temperature regulation on a mattress that needs a little extra softness and cooling.
