10 Best Memory Foam Mattress Covers 2026 in the United States

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.

The LINENSPA Memory Foam Mattress Topper offers a 3-inch thickness of gel-infused memory foam designed to soften your mattress and relieve pressure by contouring to your body. Its cooling gel infusion helps reduce heat buildup, making it a good choice if you tend to sleep hot. Made from polyurethane memory foam with gel beads, it’s CertiPUR-US certified, assuring you of safe, quality materials without harmful chemicals. The topper is easy to set up—just unroll and let it expand over 24-48 hours.

Its plush feel is ideal for those wanting to add softness and comfort to a firmer mattress or extend the life of their current mattress. However, it’s not water-resistant, so spills or heavy moisture could be an issue, and spot cleaning is recommended to maintain it. The product includes a zipper closure, suggesting some ease of use. At a queen size measuring 79 x 59 inches and weighing about 16 pounds, it’s fairly easy to handle and fits standard mattresses.

This model does not offer multiple thickness options, though LINENSPA provides a 2-inch version if less cushioning is desired. This topper is well-suited for anyone looking for affordable, pressure-relieving comfort with cooling features, especially for dorm rooms or guest beds. If you need a waterproof or more durable cover, other options may better meet those needs.
