How do you adjust the firmness?

It’s pretty simple! The Pure Mattress has two interchangeable layers that you can choose from depending on your sleeping style and overall preference for firmness.

Your mattress will arrive with the Medium-Plush firmness setting. To switch to Medium firmness, swap the 1st and 3rd layer of the mattress, with the micro coils layer in between. This will mean the Plush layer will go below the micro coils, and the Medium layer will be on top.
