It’s a standard metal frame with two sides held together by slats going across. My frame arrived on time but the screws don’t fit inside the washers that were sent in the package, so I can’t actually set up my bed. I know I’ll likely get a replacement part to remedy the issue, but I expect more from wayfair, and I still won’t have a proper bed until the pieces come. The washer holes are practically 1/4 centimeter too small, so the most frustrating part is realizing this was an error with the manufacturer and there’s probably hundreds of other people who have this same exact problem. What else can you expect from a scam front company with questionable credibility.
