Frequently Asked Questions: 

How often should I buy a new mattress? 

It is recommended that you purchase a new mattress at least every 7 to 10 years, but if you think that you mattress is causing you back pain or sleeping issues, buy a new one ASAP!

How long does it take to break in a new mattress?

New mattresses need time to fully take shape and adjust to your body. The break in period can last up to 30 days – and may even last longer. Thankfully, most mattress companies offer a trial period of 100+ nights. 

How much should I spend on a new mattress?

This question is completely personal. It depends on how fancy of a mattress you are looking for and what you can afford. Historically, mattresses have cost a pretty penny – but, it really isn’t like that anymore. Nowadays, you can easily find a quality mattress for under $500. However, if you want special features and all the bells and whistles, you’ll likely end up paying more for your new mattress. It is important to note that the price of your mattress depends on where you buy it from, what it is made of, and whether you’re getting it on sale.

What is the difference between a king and California king mattress?

Surprisingly, a king mattress has a larger surface area than a California king. In fact, a California king has the same width as a queen but it’s 4 inches longer, making it the longest mattress out there. A king has the same length as a queen, but is wider, so you get more space between sleepers.
