10 Best Memory Foam Mattress Toppers 2026 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.

This 3-inch gel memory foam mattress topper offers a comfortable and supportive sleeping experience. With a high-density of 40D (approximately 3.5 lbs per cubic foot), it provides excellent support while also being breathable due to the gel beads infused within it. As it aligns well with the body's curves and relieves pressure points, it may help reduce morning soreness and improve sleep quality.

The bamboo fiber cover, which is OEKO-TEX certified, is another highlight. It is skin-friendly, breathable, and comes with convenient features like adjustable elastic straps, an anti-slip backing, and a zipper for easy removal and washing. Additionally, the foam is CertiPUR-US certified, ensuring it meets high standards for durability and emissions.

However, it is worth noting that the mattress topper is not water-resistant, which could be a consideration for some users. The product also requires a bit of setup time, as it needs to be left in a well-ventilated area for 24-48 hours to fully expand before use. With a 10-year warranty and a free replacement policy for non-human damages within 2 years, it offers good assurance of quality. This product might be best suited for those looking to enhance their sleep comfort, particularly if they experience pressure point discomfort or need a breathable and easy-to-maintain mattress topper.
