I usually don't buy larger items aside from mirrors and stuff but I have an ikea bed frame and for the most part it's cool, I can stand and walk on the side flap thing and it's really sturdy. Will it last 10 years, probably not but I tend to change things up every few years anyway. If I was buying something that I wanted to keep for a while, I'd rather spend a little more and have peace of mind.
btw my friend has one of those type of units for her playroom and she has complained so many times about doors falling off and the whole thing just being jenky all around.
