First of all, the charcoal gray is not gray at all--it is more like that black/brown color you get from IKEA. This was a huge disappointment to me. The quality seems OK, we have ours unstacked for now, but they seem sturdy enough. There was definitely a bit of off-gassing, which is always worrying. But a real concern I have is that I have standard size twin mattresses on these and there is still a 3-4 inch gap between the mattresses and end of bed. They definitely don't take an extra-long twin, but this gap, with small children, is dangerous. I guess you get what you pay for, and hopefully we'll be transitioning out of these beds soon.
