Condition matters more than a calendar rule
Replace a mattress when comfort or support has materially declined, persistent impressions affect your sleep, the structure is damaged, or your needs have changed. Age is only a proxy. Rotating the mattress when permitted and using a suitable foundation can reduce uneven wear.
Questions to ask before you buy
- Does the firmness make sense for my primary sleep position and body weight?
- Will the construction fit my preference for contouring versus responsiveness?
- Are temperature and partner movement important enough to change the construction I choose?
- What foundation does the manufacturer require?
- What are the current trial, return-fee and warranty terms?
