It feels reasonably sturdy for plastic construction however body panels are thinner compared to Keter deck boxes which do feel sturdier.

According to manufacturer lid can support up to 176 lbs of weight. To put things in perspective Keter Sumatra 135-gallon deck box allegedly can support up to 770 lbs however we wouldn’t recommend you to try it since it sounds a bit too good to be true.

KOOLWOOM 120-Gallon deck box is very easy to assemble and doesn’t require any tools. Dissembling it however is very difficult in a sense that you will more than likely break some panels trying to do so therefore don’t expect every dissembling it unless you want to throw it out.
