How To Choose The Right Mattress

First off, if your current mattress is 7-10 years old and you're experiencing more body aches and pains, it's time to buy a new mattress. Getting a good night's sleep is essential in maintaining a healthy body and mind. Choosing the right mattress doesn't have to be a hassle, follow these guidelines to find the right one for you!

  • Choose a mattress based on your individual needs. If you're looking for plushier support that adapts to your body's shape, a memory foam mattress is the best choice. If you want a more firm, traditional, feel an innerspring mattress is what you want. For the best of both worlds, get a hybrid mattress.
  • Get proper lumbar support. The majority of your body weight is positioned in what is called the "center third" of the mattress. Find a mattress that has excellent lumbar support as it prevents and alleviates pain in the back and hips. If you're looking for extra support, Saatva's unique lumbar zone technology might be the best fit.
  • Find a mattress with a long in-home trial. You want to be able to test your mattress over an extended period of time to really make sure this is the right one for you. Look for a company that offers a risk-free in-home sleep trial. Nectar offers a 365-day trial. IDLE Sleep offers a full 18-month trial (the longest in the industry).
