Mattress Toppers

What Does a Mattress Topper Do?

A mattress topper sits on top of your mattress (underneath the fitted sheet) and modifies the feel of your sleeping surface. If your mattress is too firm, a soft memory foam or down alternative topper adds pressure-relieving cushion. If it is too soft and you are sinking, a firmer latex or high-density foam topper adds support. Toppers also create a fresh comfort layer on aging mattresses, extending their usable life by 1 to 3 years without the cost of a full replacement.

Which Topper Material Is Right for You?

How Thick Should a Mattress Topper Be?

Topper thickness determines how much it changes the feel of your mattress. A 2" topper provides light cushioning and a subtle change in firmness. A 3" topper offers a noticeable difference in comfort and is the most popular choice. A 4" topper dramatically transforms the sleeping surface and is ideal for mattresses that are significantly too firm or too worn out. For most sleepers, a 3" memory foam or gel topper hits the sweet spot between noticeable improvement and manageable bed height.

Can a Topper Fix a Too-Firm Mattress?

Yes. A memory foam or down alternative topper is the most effective solution for a mattress that feels too hard. The topper sits on top of the firm surface and creates a softer cushion that conforms to your body, relieving pressure on hips, shoulders, and knees. This is especially useful if you bought a mattress that is firmer than expected or if your comfort preferences have changed over time. For long-term comfort, explore our mattresses by comfort level to compare soft, medium, and firm options.

How Do You Keep a Mattress Topper from Sliding?

Topper sliding is one of the most common complaints. To prevent it, use a fitted sheet with deep pockets that wraps around both the topper and the mattress together. Some toppers come with elastic anchor straps or non-slip bottom surfaces. You can also place a non-slip rug pad or shelf liner between the topper and the mattress for extra grip.

Mattress Topper vs. Mattress Pad: What Is the Difference?

A mattress topper is a thick layer (2" to 4") designed to change the feel of your mattress. A mattress pad is a thin layer (usually under 1") that adds a slight cushion and protects the mattress surface. If you want to noticeably change your sleep experience, you need a topper. If you just want light padding and protection, a mattress pad is sufficient. For waterproof protection specifically, see our mattress protectors.
