10 Best Cool Mattress Toppers 2025 in the United States

The Viscose Made from Bamboo Full Mattress Topper by Niagara Sleep Solution offers multiple benefits and a few drawbacks. Its high-quality bamboo viscose material promises an ultra-soft and gentle feel, which is great for sensitive skin. With a thickness suitable for mattresses ranging from 8 to 20 inches deep, it fits well and remains secured, thanks to its stretchy sides. The cooling technology, combined with sweat-absorbent properties, ensures a comfortable sleep experience, which is ideal for those who overheat at night.

Additionally, it’s hypoallergenic, eco-friendly, and free from harsh chemicals, making it safe for most users. The topper’s dimensions are 54x75 inches, and it’s designed to enhance mattress comfort with a cloud-like cushion that could help ease back pain, making it a good option for those seeking pain relief. Maintenance is straightforward since it’s machine-washable and dries fluffy, so bed sheets stay in place.

However, it’s not water-resistant, so spills could be an issue. Some users might find it does not suit their firmness preference as it’s described as a 'hard topper.' Those needing a softer feel may need to look elsewhere. This mattress topper is a solid choice for anyone seeking a cooling, hypoallergenic, and comfortable addition to their bed.

The Ultra Soft Queen Size Mattress Topper by Niagara Sleep Solution is crafted from viscose made from bamboo, making it an eco-friendly choice that is gentle on sensitive skin. Its ultra-soft texture and cooling properties are particularly beneficial for hot sleepers, offering a comfortable and breathable sleep surface. The topper fits mattresses between 8 to 20 inches deep and measures 60x80 inches, accommodating most standard queen beds with ease.

Its 2-inch thickness adds an extra layer of cushioning, which may help alleviate back pain by providing additional support. The product is also machine-washable, enhancing its ease of use and maintenance without the presence of harmful chemicals like latex or formaldehyde. However, it is not water-resistant, so spills might require extra care to avoid damage.

While the topper is praised for its comfort and cooling effect, some users may find it lacks the firmness they prefer. Additionally, the durability of the product could be a concern for those seeking a long-term solution. Its hypoallergenic properties make it a suitable option for individuals with allergies, contributing to a healthier sleeping environment.

The Tempur-Pedic TEMPUR-Adapt + Cooling 3-Inch Queen Mattress Topper is designed for those seeking improved comfort and cooling for their mattress. One of its standout features is the 3-inch thickness of TEMPUR-ES material, which adapts well to your body shape and weight, providing personalized support. This topper is particularly appealing because it includes a cooling cover that can keep your sleeping surface up to 8° cooler throughout the night, making it ideal for warmer climates or those who tend to overheat while sleeping.

The washable cooling cover is another plus, as it offers convenience for maintaining cleanliness. The high-stretch fabric is breathable, enhancing the overall comfort. Given its size (79.5 x 59.1 inches), it fits perfectly on standard queen mattresses, making it versatile for home use or even in dorms and RVs.

There are some drawbacks to consider. The topper has a medium firmness which might not suit everyone's preference, particularly for those who prefer a firmer or softer feel. While the topper is durable, the care instructions recommend avoiding harsh cleaning agents for the core foam, which may require extra caution when cleaning. Additionally, at nearly 25 pounds, it may be heavy for some users to handle easily.
