Thick mattress toppers add a generous layer of cushioning between your body and the mattress, making them a popular choice for sleepers who want a softer, more comfortable sleep surface. A three- to four-inch mattress topper can provide enhanced pressure relief around the shoulders, hips and knees while helping refresh an older or overly firm mattress. Memory foam mattress toppers contour to your body for supportive comfort, while latex mattress toppers offer a more responsive feel with added breathability. Choose a plush mattress topper if you prefer a softer, cozy surface, or look for a firmer, supportive topper if you want cushioning without too much sink. Selecting the right mattress topper thickness depends on your sleep position, body type, preferred firmness and the condition of your current mattress. A thick mattress topper should fit securely on your bed and work with your existing sheets, so measure your mattress before shopping and check the combined height of your mattress and topper. Look for a mattress topper with a washable cover, durable construction and cooling features if you tend to sleep warm. Side sleepers often benefit from the pressure-relieving comfort of a thick memory foam topper, while back and stomach sleepers may prefer a more supportive option that helps maintain a neutral spine. Although a mattress topper can improve comfort and adjust the feel of a bed, it cannot fully correct a severely sagging or damaged mattress. Explore thick mattress toppers in twin, full, queen, king and California King sizes to find a comfortable fit for your sleep setup and get better zzz's for less.

What is a thick mattress topper? + -

A thick mattress topper is a cushioned layer designed to rest on top of a mattress. It typically has more loft than a standard topper and may be made with materials such as memory foam, latex or fiberfill.

What materials are used in thick mattress toppers? + -

Common materials include memory foam, latex, down alternative and quilted fiberfill. Each material has a different texture, structure and care process.

How thick should a mattress topper be? + -

The right thickness depends on your preferred feel and how much cushioning you want to add. Thinner options provide a lighter layer while thicker toppers create a more substantial surface.

How do you care for a thick mattress topper? + -

Care instructions vary by material and construction. Check the product label before cleaning, and use a removable, machine-washable cover when available. Avoid washing the inner filling unless the care instructions specifically allow it.

How do you keep a thick mattress topper in place? + -

Use a fitted sheet or topper straps designed to hold the layer securely. Make sure the topper is centered on the mattress and smooth out wrinkles before making the bed.
