Quite tricky assembly instructions and when assembled it feels a bit wobbly. We had to strengthen it with extra screws and it’s still wobbling. The adult weight when changing the sheets on it is fine but seems very unsteady. Don’t think it will collapse or anything but it has that uneasy feeling like when you have had a wobbly tooth. 
All in all, I think inevitably, we’re going to have to replace this one at some point with something more sturdy.
