A platform bed frame is a type of bed frame designed to support a mattress without the need for a box spring. It typically features a sturdy base made of wood or metal, with slats or a solid surface that provides even support. This design helps to elevate the mattress, allowing for better airflow and comfort. These frames come in various styles and sizes, making them suitable for different bedroom aesthetics. Many platform bed frames also include built-in storage options, such as drawers or shelves, maximizing space in smaller rooms. They are popular for their modern look and practicality.
