Our mattress toppers are exceptionally comfortable and can enhance the comfort and support of any bed, but they're not a substitute for a new mattress. Adding a topper to your existing mattress will surely provide a comfort boost, but it won't fix the issues of an old and worn mattress.
We recommend a new mattress if your mattress is unsanitary, sagging, or has divets. A mattress topper can add extra support and comfort, but it's not a replacement for a new bed.
