"Do not make the mistake of buying these shelves unless you have lots of spare time and perseverence to build them. The packaging says estimated building time is 15 minutes. They took me over 2 hours for each set. The framework is fairly solid once all the flimsey parts are fixed together but the chipboard shelves are only 7mm (thin) and so will not hold much weight unless very well spread out. Advertised capacity is over 2 tonnes. I would hesitate to load with any more than a quarter of that."
