A platform bed frame is an excellent choice for shoppers looking to create a modern bedroom. The main difference between a platform bed and a traditional bed frame is that with the platform, you don't have a boxspring underneath the mattress. The platform, usually made of wooden slats, will give your mattress plenty of support. Since regular metal bedframes usually only have 2 - 3 cross beams to as support, a box spring is necessary to make sure that your mattress doesn't sag. So save on a boxspring and spend on style by shopping for a modern platform bed on AllModern.
