FAQ

A 4-inch memory foam mattress topper provides enhanced comfort and support by conforming to your body’s shape, reducing pressure points, and improving overall sleep quality. It can also revitalize an older mattress, making it feel like new.

To care for your memory foam mattress topper, regularly air it out and spot clean any spills with a mild detergent and water. Avoid soaking the foam. Many toppers come with removable, machine-washable covers for added convenience.

Yes, memory foam toppers are excellent at absorbing movement, which means if you share your bed, you’re less likely to be disturbed by your partner’s movements during the night.

New memory foam toppers may have a slight odor, often called 'off-gassing.' This is normal and typically dissipates within a few days when the topper is aired out in a well-ventilated space.

Memory foam toppers are compatible with most mattress types, including innerspring, latex, and hybrid mattresses. Just place the topper directly on top of your existing mattress for added comfort.
