Definitely salvation and a solid solution above the rather poor wooden slats that ship even with more expensive frames these days. That said, as the frame is largely centred around the three main gables and centre beam support, for a king bed, and more specifically, a memory foam mattress, you’ll still get sagging on the sides. that said, combined with the original wood slats on top for additional support, this worked beautifully to make for a rock solid frame overall. Highly suggest hitting up YouTube for video help with assembly - while relatively easy, the sheet included can be confusing.
