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 Linenspa Memory Foam Mattress Topper is a 3-inch thick gel-infused memory foam topper designed to add plush comfort and cooling to your mattress. Its gel infusion helps capture and spread heat, which can make it a good choice if you tend to sleep hot. The memory foam gently conforms to your body, offering pressure relief and a soft, hugging feel that can improve the comfort of a firm or aging mattress.

It’s CertiPUR-US certified, meaning the materials meet safety and durability standards, and comes with a 3-year limited warranty. This topper fits queen size mattresses and is relatively easy to set up—just unroll it and let it expand within 1-2 days. However, it is not water resistant and requires spot cleaning, so spills might be tricky to manage. Also, while it offers a cozy plush feel, those who prefer a firmer surface might find it too soft.

The material is polyurethane memory foam with gel beads, but there’s no specific mention of hypoallergenic features beyond being tick-repellent. Given its price point and solid customer ratings, this topper suits anyone looking to soften a firm mattress or add cooling comfort without investing in a new mattress, especially for dorm rooms or guest beds.

The LINENSPA Memory Foam Mattress Topper is designed for those seeking extra comfort and cooling features in their sleep setup. Made from gel-infused memory foam, it adapts to your body's curves, providing personalized comfort while also aiming to keep you cool through its cooling gel infusions. This topper is especially beneficial for those who find their current mattress too firm or for rejuvenating an older mattress without a full replacement.

Available in a 2-inch thickness, it offers a plush feel without being too overwhelming for most sleepers. One of its strong points is ease of setup – it comes compressed and unfolds to its full size within 24-48 hours without requiring any assembly. The material quality is assured with a CertiPUR-US certification, ensuring it is made from safe and durable components. This product is also hypoallergenic, making it a good choice for those with allergies.

However, it is not water-resistant and can only be spot cleaned, which might be a limitation for some users. Another consideration is that it is not the thickest option available, which might be a drawback for those looking for extra cushioning. The topper comes with a 3-year warranty, indicating a moderate level of durability. In summary, the LINENSPA Memory Foam Mattress Topper is well-suited for individuals looking for a cooling, comfortable addition to their bed, with the convenience of easy setup and moderate durability, but it may not be ideal for those needing extensive water resistance or thicker padding.
