Frequently Asked Questions
With so many options on the market, it can be difficult to find the perfect mattress and pillow. That’s why we designed a quick, informative Sleep Quiz to help you understand your unique sleep preferences and find the best fit for your needs. Looking for more tips? Our Blog is full of information to help you make the right decision. We recommend taking a look at Mattress 101 and Perfect Pillows.
You can take a look at our Blog to learn more about latex and memory foam. In summary, natural latex is made from the sap of rubber trees, whereas memory foam was invented by NASA’s space program. Both materials are known for contouring your body, therefore providing excellent support, comfort, and motion isolation. Latex tends to sleep cooler than memory foam due to its breathability.
We recommend replacing your mattress every 5 to 7 years. Depending on the material, pillows should be replaced between every 6 months for polyester to every 2 to 3 years for more durable materials such as latex and memory foam. After all, you spend ⅓ of your life in your bed, so you need to be sure you’re getting the best sleep possible.
