10 Best Mattress Toppers 2025 in the United States

The Tempur-Pedic TEMPUR-Adapt + Cooling mattress topper features a 3-inch layer of memory foam designed to adapt closely to your body shape and weight, greatly enhancing the comfort and support of an existing twin XL mattress. Its cooling feature includes a washable, breathable cover that feels cool to the touch and helps regulate temperature during sleep, making it ideal for those who tend to overheat at night. The memory foam material provides excellent pressure relief, suitable for people seeking a softer sleeping surface without losing support.

This topper weighs over 16 pounds, which may make moving or adjusting it somewhat cumbersome. Cleaning involves dry cleaning for the foam and washing the cover separately, which might be less convenient compared to toppers with machine-washable components. It is not water resistant, so spills could be problematic. The firmness tends toward soft due to the memory foam, which may not suit those preferring a firmer feel. This topper is well-suited for upgrading an existing mattress for enhanced comfort and temperature control, particularly in settings like dorm rooms, guest beds, or RVs.

The ChiXpace Dual Layer 4 Inch Memory Foam Mattress Topper is designed to enhance comfort with its 2-inch gel-infused memory foam layer combined with a 2-inch quilted pillow top filled with soft down alternative fiber. This dual-layer setup offers a good balance of cushioning and support, thanks in part to the 7-zone egg crate pattern that helps distribute weight evenly and relieve pressure points. The gel memory foam helps keep the surface cooler, which is a big plus if you tend to sleep hot.

The topper also features a removable, machine-washable cover, making it easier to keep clean and fresh. Its materials are hypoallergenic, suitable for sensitive sleepers who want to avoid allergens. It is not water resistant, so spills might be a concern if you don’t use a mattress protector. At 4 inches thick, it adds noticeable softness without being overly plush, making it a solid choice for those who want to soften a firm mattress while maintaining support.

Some users might detect a slight foam smell initially, but it fades after airing out. This makes it an inviting option for adults looking to upgrade their sleep surface with comfort, cooling, and easy maintenance, especially if you have a California King bed.

The TEMPUR-Adapt (Supreme) mattress topper is made from memory foam that adapts closely to your body shape and weight, providing medium firmness that balances comfort and support. At 3 inches thick, it’s substantial enough to noticeably soften a mattress and relieve pressure points, which can help reduce tossing and turning during the night. This topper is especially good if you share your bed because it significantly reduces motion transfer, meaning you’re less likely to feel your partner’s movements.

Its temperature sensitivity means it adjusts to your body heat, though memory foam can sometimes retain warmth more than other materials, so very hot sleepers might feel a bit warm. The hypoallergenic and machine-washable cover makes cleaning easy and helps with allergy concerns, which is a bonus for sensitive users. The included Staytight corner straps keep the topper securely in place, so you don’t have to worry about shifting during sleep.

While the memory foam offers great pressure relief, it’s not water resistant and may feel a bit firm if you prefer a very soft sleeping surface. This queen-size topper is a solid choice for those looking to improve mattress comfort without replacing their entire mattress, especially if you want pressure relief and less disturbance from movement.
