The assembly of this bed frame was incredibly straightforward. It is very sturdy, even with a heavy memory foam mattress on top. I was initially worried about the slats being spaced too far apart and having the mattress fall between them. However, I can see that the slats support the weight evenly. Im incredibly happy with this purchase. I love that the bed sits within the frame and doesnt slide around like it would on a platform bed frame. The price was perfect, with other comparable king bed frames being of lesser quality in this price range. I noticed that other bed frames weight capacity is nowhere near that of this Metal Steel Slate Bed Frame, that alone was the biggest seller for me.
