    There is no strict rule about when to replace your mattress, but most have a lifespan of around eight years. Some experts say this timeframe is shorter if you’re over 40, because your body may need a better foundation for sleep.

    The best way to tell if your mattress has seen its day is to evaluate your comfort and sleep quality. Check for worn or sagging spots in the middle or at the edges, and make sure that when your partner moves, your position on the bed isn’t disturbed. If you wake up tired or stiff, or if you find hotel beds extra cozy, it could be a clue that it’s time for a change.

    Give your pillows the same once-over for lumps and sags. When you sleep, your pillow should support your head and neck, allowing them to stay in a neutral position (without craning or awkwardness) while you sleep. Many doctors recommend replacing pillows every two years.

    In the meantime, keep your mattress and pillows clean. Wash your mattress cover in hot water. You can also dust the mattress itself with baking soda to draw out moisture and vacuum it up a day later, or wash with a product such as upholstery cleaner. Most pillows are washable, or can be run through the dryer on high temperature to kill dust mites.
