How often you should buy a new mattress (plus President's Day deals on mattresses)

If you've been having a hard time falling asleep, your mattress might be the cause. 

Your mattress is not meant to last forever. So if you've been sleeping on the same mattress for a number of years, chances are your mattress probably isn't as comfortable as it used to be. Mattresses can be damaged a number of ways: the sleeping indentations of people and pets can cause heat-trapping lumps and bumps and sagging. Mold can be caused by humidifiers, ceiling leaks, sitting on your mattress in a wet towel or even heavily sweating in your sleep.

If an old, lumpy, sagging and potentially moldy mattress isn't allowing you to sleep comfortably, you're likely not getting the benefits of a good night's sleep. Sleep is important for vital functions such as neural development, learning, memory, emotional regulation, cardiovascular and metabolic function, and cellular toxin removal.

So when should you buy a new mattress

When to buy a new mattress

According to the American Sleep Association, you should replace your mattress every 8 to 10 уеаrѕ. 

To extend the life of your mattress, use a washable mattress protector. A protector can keep your mattress clean and dry, prevent mold, and resist dust mites. The ASA further advises rotating your mattress 180 degrees at least once every 90 days, for more even wear. If you have a double-sided mattress, you should also flip it. Double-sided mattresses are designed to be used on both sides. 

Of course, if the mattress you own just isn't feeling comfortable anymore, now's a great time to replace it regardless of when you bought it.
