The Nerd’s Take: The Lift mattress topper is a 3″ memory foam topper with two firmness options. The Comfort topper is designed for responsive comfort, while the Support topper is intended for pressure-relieving support. Both toppers come with a removable, breathable cover and feature open-cell memory foam to wick away warm air.

The Lift mattress topper from Amerisleep comes in a choice of firmness options. The Comfort Lift topper has a soft, cushioning feel that responds well, minimizing the “stuck” feeling of traditional memory foam

The Support Lift topper has a firmer feel. It’s designed to be ultra-supportive so sleepers maintain a neutral spine while still feeling cushioned around the hips and shoulders.

Both toppers feature Amerisleep’s HIVE technology, which stands for Harnessing Intelligent Ventilation and Energy. It’s a hexagonal pattern with more support in the heavier parts of the body, which helps reduce pressure point pain.

Temperature Control: 4/5

Memory foam doesn’t have a reputation for cooler sleep, but the Bio-Pur and Affinity materials used in both versions of the Amerisleep topper have an open-cell design. This helps wick away warm air to keep you from overheating. Self-described hot sleepers say the topper does a good job of keeping them from getting too warm at night. 

Alignment: 5/5

Because it contours closely, memory foam tends to be a good option for maintaining alignment. The Affinity material in the Support Lift is a better pick if you’re looking for firm support, while the Comfort Lift topper is softly contouring. In both cases, you can expect great alignment.

Motion Isolation: 5/5

Memory foam isolates motion well, so both the Comfort and Support Lift toppers are a good choice if you share your bed with a partner and need to minimize disruptions at night.

Quality of Materials: 4/5

Bio-Pur and Affinity are high-quality materials, so these mattress toppers should perform comfortably for at least five years. That’s reflected in their five-year warranty, which covers deterioration in the foam that causes visible indentations exceeding .75 of an inch. However, neither topper is hypoallergenic, so if that’s a priority, you’ll need to keep shopping.

Care: 4/5

The cover can be zipped off for machine washing, but Amerisleep recommends hanging it to dry. The actual topper cannot be washed, so the company strongly recommends that you use a protector to guard it against spills, sweat, or accidents.

Customer Experience: 3/5

While Amerisleep does offer free shipping and a generous five-year warranty, there is no sleep trial available for its mattress toppers. Many other brands offer free returns on their mattress toppers within a trial window, so

Total Score: 4.2/5

Materials and Construction: What’s It Made of?

The Comfort Lift topper is made with Bio-Pur, a memory foam that’s partially made with renewable plant-based oils. It’s a three-inch topper with a soft, contouring feel and works well for those who want to add a layer of extra cushioning to their current mattress. It’s also well-suited to side sleepers, and because it’s more responsive than typical memory foam, it can accommodate combination sleepers nicely.

The Support Lift topper is made with Amerisleep’s Affinity material, a transitional memory foam material that’s ultra supportive to maintain a neutral spine while still cushioning the hips and shoulders. This topper is also 3″ tall, with a firmer, supported feel that works well for back and stomach sleepers.

Both materials have an open-cell design for cooler, more comfortable sleep, and both toppers include a soft, breathable cover.



  • Choice of firmness: With the Comfort and Support Lift toppers, shoppers can choose a firmness that will best suit their sleep style.
  • Wide range of sizes: The Lift topper is available in multiple sizes, from twin up to California king.
  • Cooling and pressure-relieving: HIVE technology makes these toppers cooler and gently contouring, with more support in targeted areas to help reduce pressure point pain.


  • High price point: Prices range from over $300 for a twin to over $500 for a California king, so these toppers may not work for everyone’s budgets.
  • No sleep trial: Shoppers who aren’t sure which topper firmness they prefer may be concerned about the lack of a sleep trial.

Are mattress toppers good for your bed? 

Mattress toppers can be a great addition if your current mattress is lacking in comfort or support and a new mattress is out of your price range. These layers are designed to add features like pressure relief, cooling benefits, softness, or support to enhance your sleep experience.

Who owns Amerisleep? 

Amerisleep was founded by Firas Kittaneh, Moe Kittaneh, and Joey Holt in 2010. It was among the first online mattress companies and takes a non-traditional approach to retail showrooms as well. The company manufactures its mattresses in the U.S. and prioritizes eco-friendly, plant-based materials that are certified by CertiPUR-US.

What is the lifespan of a mattress topper?

The lifespan of a mattress topper will vary depending on the material from which it’s made. Like a mattress, material quality is important and dictates longevity. Generally, mattress toppers will last between 3 and 5 years, but that will depend on how it’s made and used.

Should You Buy It?

The Lift mattress topper from Amerisleep is a high-quality memory foam option available in a choice of two firmnesses. The Comfort Lift is a three-inch topper designed to add a cushioning but responsive layer for side and combination sleepers. The Support Lift is also three inches in height, with a firm, supportive feel that works well for back and stomach sleepers.

On the downside, these are pricey options and Amerisleep doesn’t offer a sleep trial. However, if you’re looking for a breathable memory topper and you’re clear on whether you’d prefer to add a layer of cushion or support to your existing mattress, the Lift topper is a great option.
