10 Best Memory Foam Mattress Toppers 2025 in the United States

The Tempur-Pedic TEMPUR-Adapt + Cooling mattress topper is a 3-inch memory foam layer designed to fit a queen mattress perfectly. Its medium firmness offers a balanced level of comfort without sinking too much. The unique TEMPUR-ES foam adapts to your body shape and weight, which can improve support and reduce pressure points for a better night's sleep.

One standout feature is its cooling cover made of breathable, stretchy fabric that stays cool to the touch and can be removed and washed, helping you stay comfortable through the night and keep the topper fresh. The topper is designed to keep you up to 8 degrees cooler, which is beneficial for those who tend to sleep hot.

With a solid customer rating of 4.1 out of 5, many users appreciate its comfort and cooling benefits, though some might find it less firm or supportive depending on personal preference. This topper is ideal for anyone looking to enhance their current mattress with a medium-firm, cooling, and washable option, whether at home, in dorms, or even for travel uses.

The TEMPUR-Adapt (Supreme) 3" Memory Foam Mattress Topper is a solid choice if you want to add extra comfort to your existing mattress. At 3 inches thick, it provides noticeable cushioning and uses the same TEMPUR material known for adapting to your body’s shape, weight, and temperature. This means the topper offers personalized pressure relief and medium firmness, which should suit most sleepers looking for balanced support without feeling too soft or too hard.

Its density and durable foam also mean it maintains comfort over time without sagging quickly. The washable, breathable cover is a nice practical touch, keeping allergens and dust at bay and making maintenance easy. However, this topper does not have specific cooling technology beyond the breathable cover, so if you tend to sleep hot, it might not be the best option. Also, it’s not water resistant, so spills could be a concern.

Though priced higher than average toppers, the quality and durability justify the investment for those wanting a long-lasting upgrade. This product suits adults seeking medium firm support and pressure relief, especially for improving a mattress that’s too firm or starting to feel uncomfortable. If you prioritize cooling features or need water resistance, you might want to look elsewhere.

The Linenspa 3 Inch Gel Swirl Memory Foam Mattress Topper is a solid choice if you're looking to add extra comfort to your bed without replacing your mattress. At 3 inches thick, it offers a noticeable plushness that softens a firm mattress or refreshes an older one. The medium firmness level provides balanced support, which suits many sleepers who want cushioning without sinking too much. It’s infused with cooling gel beads designed to help reduce heat buildup, making it breathable and more comfortable for warm sleepers. This topper is also ventilated, which further enhances airflow. The memory foam material contours to your body, relieving pressure points, which is great for side or back sleepers seeking relief.

It’s CertiPUR-US certified, so you can trust it’s made without harmful chemicals and should be durable. The cover is made from hypoallergenic memory foam, but it isn’t water-resistant, so spills could be an issue. Also, while it’s machine washable, care instructions should be followed carefully to maintain the topper’s quality. The product is easy to set up, expanding fully within a day or two after unpacking. On the downside, it weighs about 5.7 pounds, which is manageable but might be a bit much to move frequently.

This topper is available in multiple thickness options, but the 3-inch model strikes a good middle ground for softness and support. It represents a practical and affordable option for anyone wanting to improve mattress comfort with some cooling benefits, especially suited for those who prefer medium firmness and need pressure relief.
