When should I upgrade my mattress?

There's no set expiration date, but you can expect a good mattress to last at least 8 to 10 years, according to Lexie Sachs, the executive director of the GH Institute Textiles, Paper & Apparel Lab. Warning signs, like lumps or indents, are a solid indicator that it's time to replace your mattress. Note whether your mattress is causing difficulty sleeping or pain upon waking, too. The better you take care of your mattress, the longer it'll last. Make sure to use a mattress protector to protect from everyday wear and tear. Plus, it's a good idea to clean your mattress every few months to keep it fresh.
