Very happy with this purchase (Bought 2). My biggest concern need was to accommodate two adults on the bottom bunk when needed, plus a tween/child up top. There is a solid metal bar that runs down the middle of both the top and bottom bunk for support and BOTH levels are rated to support a 400lb weight capacity. Huge selling point for me. These bunk beds don't need a center support leg, meaning they can also be used with trundles. I bought a separate trundle frame for one of the rooms and it works really well. My only complaint (Minor) is that the wood can scratch from the ladder movement. This is a small issue as we leave the ladder on, but since it is technically removable, I would have loved to see a better way to protect the wood from the metal supports that hold the ladder on. Again, being nitpicky. Great product and would order again.
