This is super sturdy. I thought it was going to be that thin walled type of foldable storage.  But it's hard plastic. It arrives flat but in 5 steps its completely assembled and it feels very sturdy. We have only tested a combined weight of 300lbs of sitting on it when it was empty.  Also, it looks expensive. It can't believe this unit was foldable and is this quality. I will update if I discover any flaws after extended use from my dog and kids.
