How do I choose the right mattress?

The first step in choosing the right mattress is to consider your preferred sleeping position. Are you a side-sleeper, back sleeper or stomach sleeper? Then, you'll want to consider your firmness preference. You should also consider if you have any issues that affect your health, like chronic back pain, allergies and even your weight and body type. Of course you should also consider your budget for a mattress as well. You can also try Helix Sleep's short sleep quiz to help you find the perfect fit!

How often should I replace my mattress?

It's usually recommended to replace your mattress every seven to 10 years, depending on its condition and your sleep quality. Pay attention to signs that it is time to buy a new mattress including if your sleeper is sagging or lumpy, and if you have discomfort while sleeping or wake up with aches and pains.
