A plush comfort level is a number or level that tells a shopper how plush or soft a mattress is. Typically, mattresses that are labeled as “plush” fall somewhere on the 1-3 range in terms of firmness. The lower the plush comfort level, the less firm your bed will be. To find your ideal plush comfort level, we recommend lying on a variety of different mattresses before you buy. This will give you an idea of your personal preference when it comes to softness and support.
