If you’re curious about what this bed frame looks like, think of the swirls of an ancient scroll or the curvy silhouette of a sleigh. Remember that this style can add even more inches to each side of the frame, so sleep spaces with a little more length are best to host this impressive frame.3
Typically designed without a headboard or footboard, a platform bed creates a clean, modern aesthetic. With this simple style, you don’t have to invest in a box spring — the platform bed is a base and frame all in one.3 Learn more about the panel bed vs platform bed and the types of platform beds in our blog to help you find what’s best for you.

Compatible with any mattress, solid foundations work well with memory foam, latex, and hybrid mattresses, too.4 Learn more about a box spring vs foundation in our blog.
