This bunk bed is NOT "robust". Bulky, sure, but sturdy? Absolutely not! Im actually worried about the stability of this thing because it shakes with a soft push. Im thinking for the safety of my average sized 8yo, who's very mellow and not rambunctious, I may need to dismantle and return. I was really hoping it wouldn't wobble due to it being wood, but it wobbles worse than the cheap metal bunk bed that I had as a kid. I wish i could upload a video to show you how much this massive piece of furniture moves at the slightest of touch.
