Thick Mattress Toppers

The right thickness depends on your sleep needs. A 2-inch topper adds a touch of softness to a firm bed, while 3 inches creates a balanced mix of comfort and support. For the most noticeable change, a 4-inch extra thick mattress topper delivers maximum pressure relief and cushioning.

Yes, a thick memory foam mattress topper can help relieve back pain by evenly distributing weight and reducing pressure points. When the foam contours to your body, it supports the natural curve of your spine, which may ease lower back strain. For many of our customers, adding a thick topper is an effective alternative to replacing a mattress that feels too firm.

Not necessarily. A mattress topper thick enough to add comfort is designed to enhance, not replace, the support of your mattress. The key is choosing the right density and thickness for your sleep style. For example, side sleepers often enjoy thicker, softer toppers, while back and stomach sleepers may prefer firmer foam to avoid sinking too much.

A mattress pad is usually thinner, designed to protect your mattress and add a light layer of softness. A thick mattress topper, however, changes the overall feel of your bed by improving support, cushioning, and durability. Many sleepers choose to use both: the pad adds plush surface comfort and protection, while the topper delivers the deeper pressure relief and support.

Older foam toppers often retained heat, but today’s designs are much more advanced. At Viscosoft, for example, our thick cooling mattress toppers use breathable foams and gel-infused technology to reduce heat buildup and keep you comfortable throughout the night. If you tend to sleep hot, look for a topper specifically engineered for airflow and cooling.

Thicker toppers add extra height to your bed, which means standard sheets may not always fit snugly. Deep-pocket fitted sheets are often recommended when using a 3 or 4-inch thick foam mattress topper. We suggest measuring the combined height of your mattress and topper to ensure a proper fit.

Absolutely. Side sleepers often experience pressure on their shoulders and hips, and a thick memory foam mattress topper helps cushion these areas for better alignment. A 3- to 4-inch topper is usually best for side sleepers who want to reduce stiffness and wake up more refreshed.

Most thick mattress toppers come with a removable, washable cover, which makes cleaning much easier. Foam cores should not be machine-washed, but they can be spot cleaned and aired out regularly to stay fresh. Using a mattress pad or protector over your topper adds an extra layer of defense against spills and allergens.
