10 Best Memory Foam Mattress Covers 2026 in the United States

The Linenspa 3 Inch Gel Swirl Memory Foam Mattress Topper is designed to add comfort and cooling to your existing mattress. Its 3-inch thickness offers a medium firmness that can soften a hard mattress or refresh an older one. The topper is made from gel-infused memory foam, which helps relieve pressure by contouring to your body, making it more comfortable to sleep.

The cooling gel beads and ventilation work together to reduce heat buildup, which is great if you tend to sleep hot. It’s also CertiPUR-US certified, meaning the foam meets certain standards for safety and durability. The cover is made of 100% polyurethane memory foam and is machine washable, which helps keep it clean and fresh. Setup is simple since it arrives compressed and expands fully within a day or two.

On the downside, this topper is not water-resistant, so spills could be an issue without extra protection. Also, while it has cooling features, some users might find it less effective during very warm nights compared to toppers with advanced cooling fabrics. For those wanting a mattress topper that balances pressure relief and cooling with an easy setup and trusted certification, this Linenspa model is a solid choice, especially for improving a current mattress without buying a new one.

The Tempur-Pedic TEMPUR-Adapt + Cooling 3-Inch Queen Mattress Topper is designed for those looking to enhance the comfort and support of their existing mattress. One of its standout features is the 3-inch thickness of TEMPUR-ES material that adapts to your body shape, weight, and temperature, offering a personalized sleep experience.

The medium firmness strikes a balance between softness and support, making it suitable for a wide range of sleepers. Additionally, the premium knit cover is not only washable but also provides a cooling effect, which can be beneficial for those who tend to sleep hot. The topper claims to keep you up to 8 degrees cooler throughout the night, enhancing sleep quality in warmer conditions.

The topper's versatile use is a plus, as it can be easily set up in various settings including dorm rooms, recreational vehicles, and for accommodating overnight guests. However, it is important to note that the topper is relatively heavy at 24.8 pounds, which might make handling and moving it a bit cumbersome for some users. Also, while the cooling cover is washable, the core TEMPUR material should not be washed or dry cleaned, requiring careful handling. The topper is not water-resistant, so additional protection may be needed to prevent damage from spills.

The VALUXE 3 Inch Gel Memory Foam Mattress Topper King Size is designed to enhance your sleep quality with its high-density memory foam and cooling gel beads. The 3-inch thickness ensures plenty of cushioning, while the 40D (3.5 lbs/cubic foot) density provides ample support and durability. An added bonus is the bamboo fiber cover, which is breathable, skin-friendly, and removable for easy washing.

The cover also features adjustable elastic straps and an anti-slip backing to keep it in place, plus it's OEKO-TEX certified for safety. The cooling features are a nice touch, as the gel beads help maintain air permeability to regulate temperature and prevent overheating during the night. The CertiPUR-US certification adds peace of mind regarding the foam's content, emissions, and durability.

However, this topper is not water-resistant, so it may not be ideal for environments prone to spills. It also requires proper setup, including unzipping and airing out for 24-48 hours before use. The topper is relatively heavy at 26 pounds, which might make handling a bit cumbersome for some users. Despite these minor cons, it stands out in the market. If you're looking for a mattress topper that offers comfort, support, and cooling properties, this could be a great choice for you.
