People most commonly compare platform beds to box springs. Both are bed bases, although a platform bed doubles as a bed frame. A traditional box spring is made of either wood or metal. It is the size of your mattress and holds within it metal springs that respond to pressure from the mattress on top. This makes box springs designed specifically to support innerspring beddings. They also offer less variety of styles and options as compared to platform beds. While they can sometimes be the most cost-efficient option, they are usually not as sturdy or durable as other options, including platform beds. They are often the bounciest option but this can also cause it to be noisy, something you don’t have to worry about with platform beds.
