Visible deterioration

Persistent sagging, damaged components or structural failure are clear reasons to investigate replacement.

Comfort has changed

If a mattress that once felt comfortable now consistently feels uneven or unsupportive, wear may be part of the problem.

Your needs can change too

Body changes, a new partner or changing sleep preferences can make an otherwise intact mattress a worse fit.

Check the foundation

Before replacing the mattress, inspect the base or frame for broken slats, poor support or obvious deflection.

Use this when comparing real mattresses

Take the construction principle above and compare it against the manufacturer's current specifications, trial terms and warranty rather than relying on marketing labels alone.
