10 Best Cool Mattress Toppers 2025 in the United States

The Mattress Topper Full from IULULU is a solid choice for those looking to enhance their sleep experience with a cooling mattress topper. Made from gel-infused memory foam, it is designed to provide a cool and comfortable sleeping surface by incorporating a ventilated design with air holes to help manage moisture and sweat.

It comes in two thickness options (2-inch and 3-inch), allowing users to choose the level of support and cushioning that best suits their needs. The 3-inch version offers more substantial support, which can be beneficial for those needing extra pressure relief and body contouring.

This topper is CertiPUR-US Certified, ensuring the foam's durability, performance, and safe content quality, making it a reliable and long-lasting option. The topper is easy to set up, arriving compressed in a box for convenient shipping and handling. Users should allow 48-72 hours for full expansion, especially in cooler environments. One of its practical benefits is the ability to improve mattress comfort while protecting the mattress itself. However, it is not water-resistant and requires careful handling as it cannot be washed. Additionally, while it provides cooling properties, some users may find that it does not significantly lower the sleeping temperature. The topper’s size fits a full-sized bed, and its blue color adds a touch of style.

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.
