This is a beautiful piece of furniture. Although it's not top-of-the-line quality, the appearance suggests otherwise. However, for a king-sized mattress, including only 4 slats for a platform bed that doesn't require a box spring is not nearly enough. We will be supplementing the slats with plywood because the mattress we purchased sags in between the slats. (By comparison, a full-sized platform bed purchased from another company for our daughter contained 12 slats. BIG difference!) Would strongly recommend the manufacturer increase the number of slats to at least 12 slats for all bed sizes.
