Is It Time for a New Mattress?
How do you know if the bed you're sleeping on is the right one?
"If you wake up in the morning and have some low back pain and can stretch and get rid of it in 15 or 30 minutes, that means you're on an inappropriate mattress for you," Breus says.
The right mattress, on the other hand, is one on which you feel no pressure, almost like you're floating in air, Breus says.
If you're looking for a new mattress, experts suggest testing it in the store and laying down on each mattress in the position in which you normally sleep. Breus suggests spending at least 10 to 15 minutes on the bed. And, bring your own pillow! The more you can replicate the way you'll be sleeping on the mattress once you get it home, the better your chances of picking the right one.
When to Part With Your Old Mattress
Today's mattresses are made to last a lifetime. But you probably shouldn't plan on keeping yours for that long. Our bodies change over time, Breus says, so the mattress that was once a joy to sleep on may no longer feel comfortable a few years down the road.
In addition, mattresses collect dust mites, fungus, and other germs that can exacerbate allergies and impact your sleep patterns. After 6-10 years, it's time to think about buying a new bed.
