Mattress topper vs New mattress
Evergreen URL: /compare/mattress-topper-vs-new-mattress
In short
A mattress topper changes how the top of your bed feels. A new mattress replaces the support underneath. A topper can soften a firm mattress or add a fresh comfort layer, but it cannot fix sagging, deep dips or broken springs. If the support has gone, replace the mattress instead.
This comparison helps you decide whether a topper is enough. Start by checking the mattress itself: dips, lumps, noisy or broken springs, and its age.

Frequently asked questions
Can a topper fix a sagging mattress?
No. A topper only changes the top feel. A dip or broken support will show through the topper over time. Replacing the mattress fixes the support.
Will a topper change my sheet size?
It can. A topper adds height, so you may need fitted sheets with deeper pockets. Measure the mattress and topper together before you buy sheets.
When should I replace my mattress instead of buying a topper?
Replace it when the support has gone: visible dips, broken or noisy springs, or rolling into a hollow. Age is a clue, not a rule.
