Wood and metal bed frames are similar in that they’re both options for supporting your mattress. The main difference is actually the price point. Since wood is most often a more expensive material, metal bed frames tend to run a bit cheaper than their wooden counterparts. However, this isn’t true in all cases. Another major difference is the slats. Wooden beds typically come with wooden slats, and metal bed frames often come with metal slats. Both wooden and metal bed frames can be high quality, although wood is often regarded as a more durable material.
