Foam Fundamentals: Comparing Cushion Foam Densities for Comfort, Durability, and Outdoor Use - From Leon Custom Upholstery

When reupholstering furniture, cushion comfort is everything. And that comfort starts with what’s inside — the foam. At Leon Custom Upholstery, we help clients understand how foam density affects comfort, longevity, and performance. In this post, we’ll explore the different types of foam densities using both PCF (pounds per cubic foot) and HR foam grading systems such as HR35, HR40, and HR50, plus we'll discuss the best applications — including for outdoor use with Dry Fast Foam.
