The cube organizer arrived about a week earlier than the estimated delivery date, which was great. The package was heavier than I expected and it seems very sturdy and good quality. In the listing online it doesn’t give a weight capacity for each shelf but in the instruction manual it says 15lbs per individual shelf and 35 lbs on top (see attached picture). It was fairly easy to put together but I had to use a flashlight a few times to make sure I was aligning the holes correctly. Overall I’m very impressed and may get a second one.
