If you’re thinking about purchasing a new mattress you’re probably fretting over whether you should buy a soft mattress or a firm mattress. Luckily, we’re here to help.


Who should buy a firm mattress?

There is still a lot of debate about this, but recent research shows that a firm mattress might not be so great for people with back problems because of the areas it puts pressure on. People with back pain should stick to a medium-firm mattress. Healthy people, on the other hand, can generally benefit from a somewhat firmer mattress.

Still, personal comfort is a huge factor in the quality of your sleep, so you should make sure to properly sleep-test your bed by lying on it in the position you normally sleep in for as long as possible before you actually make a purchase.

Why do firm mattresses help?

A firm mattress makes it easier for you to breathe deeply during sleep. Oxygen is necessary to repair your body, so the amount of oxygen you receive while sleeping has a profound impact on the quality of your sleep.

Tips for an effective sleep test

Properly testing a mattress before you buy it is the only real way to figure out whether or not the mattress will work for you. There are a few different things you can do to make your sleep test more effective:

  • Set a timer for 20 minutes when you lie down to test the bed and make sure you don’t get up before it goes off
  • Sleep in a position as close to the position you would regularly sleep in as possible. You might even want to take off your shoes so you can get really comfortable
  • Bring your own pillow with you to replicate your home sleeping experience more closely—unless of course you’re also looking for a new pillow, in which case make sure to find your ideal pillow first and then test it with different mattresses
  • Wear comfortable clothing so it’s easy for you to relax during the sleep test
  • Focus on breathing deeply to replicate how you breathe during your sleep.
