Most mattresses are rated for eight to ten years, but plenty wear out faster simply because of how they're used day to day — and plenty last longer for the same reason.

Rotate it, even if it's "no-flip"

Modern mattresses usually don't need flipping top to bottom, but rotating head-to-foot every few months prevents one section from taking all the body-weight impact. Without this, a permanent body impression can form years earlier than it should.

Let it breathe before making the bed

Pulling the sheets back for even 15–20 minutes after waking up lets overnight moisture evaporate instead of getting sealed back in under the covers. It's a tiny habit that meaningfully reduces the damp environment mites and mold prefer.

A protector is cheaper than it looks

A breathable mattress protector blocks spills, sweat, and skin cells from reaching the mattress itself, and it's machine washable — which means the parts you can't clean easily stay cleaner for longer just by using one.

None of these take more than a minute or two, but together they're often the real difference between a mattress that needs replacing at year six and one that's still comfortable at year ten.
