This End Up furniture is very sturdy solid wood. It is often used in college dorms, or at least is was when I was there
We have a table from This End Up and it's wonderful. We use it for games, art, crafting, and at dinnertime we clear it off and eat there. Because it is solid wood, we can sand it down to remove paint, markers, etc. With a bit of wood polish it is good as new. I'd check out the bunk beds from this company if I were in the market for some.
