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 DUMOS Memory Foam Mattress Topper is a 3-inch thick gel-infused foam pad designed to improve comfort for queen-size beds, sleeper sofas, and even RVs. Its high-density memory foam offers solid support by evenly distributing body pressure, which helps reduce aches and adapt to different sleeping positions. A standout feature is its cooling gel beads combined with vortex technology, promoting airflow to keep you feeling cooler throughout the night—a useful benefit if you tend to overheat on traditional memory foam.

The topper is made with CertiPUR-US certified materials, ensuring it is safe and free from harmful chemicals, which is a great choice for sensitive skin. The fabric is breathable but the topper is not water-resistant, so spills should be avoided. It comes compressed for shipping and needs about 24 hours to fully expand to its original shape.

This mattress topper is a suitable choice for anyone looking for enhanced comfort and cooler sleep without investing in a new mattress, especially those sensitive to heat or chemicals. However, if you want something water-resistant or firmer support, you might want to explore other options.
