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.

This Ultra Soft Twin XL mattress topper by Niagara Sleep Solution is a good choice for anyone looking to add softness and cooling comfort to their bed, especially if you sleep hot or have sensitive skin. Made from bamboo viscose, it offers a naturally breathable and sweat-absorbent surface that helps keep you cool through the night. The topper is also designed to relieve back pain by adding a cloud-like cushioning layer, which can be great if your current mattress feels too firm or worn out.

Its deep pockets and stretchy sides make it easy to fit over thicker mattresses, including extra-long Twin XL sizes. You can also toss it in the washing machine without losing its fluffiness, which adds convenience. On the downside, this topper isn’t water resistant, so spills or stains might be harder to manage. While the focus on softness means it might not suit those who prefer a firmer sleeping surface, the fabric blend suggests reasonable durability, although heavy use over time could reduce its plush feel.

This mattress topper offers a cool, hypoallergenic, and comfortable option for back pain relief and hot sleepers, particularly for those seeking an easy-to-maintain topper that fits longer beds.
