The bed has 4 slats, the mattress was bulging between them making sleeping on the bed impossibly uncomfortable. I had to go to The Home Depot, get some lumber, measure, cut and attach to the frame creating additional slats. It demanded so much time an extra money. When one buys a bed one expects a bed that can be slept on, not a half made product. I don't think it is unreasonable to expect a bed to come with enough slats!
