This is a really great bunk! I was surprised by the number of slats underneath each mattress area—I was ready to purchase more because I expected it would be shoddy, however, I did not need to since there were so many slats already included. They are all attached to one another, too, so installation is a breeze. Some of the slats were a tiny bit short, so I had to lean into the frame of the bottom bunk to screw the slats in, but once I did that, there wasn’t an issue. My kids have used their bunks the past few days, and they are really enjoying them!
