how often to change mattress

Mattresses should generally be changed every 6 to 8 years to ensure proper support, comfort, and hygiene. Memory foam mattresses can last longer, about 10 to 20 years, while innerspring mattresses usually last around 5.5 to 6.5 years. The need for replacement also depends on factors like comfort, presence of sagging or damage, increased allergies, and sleep quality. If the mattress is causing aches, discomfort, or worsened allergies, it's a sign to replace it sooner. Regular flipping and rotating can extend mattress life. Ultimately, if the mattress no longer provides restful sleep, it should be changed.
