Very solid! I had 2 rubbish argos rails that all snapped and were flimsy and shaky. This one rail now holds content of a wardrobe and those 2 rails no problem. At least 80kg. As there some heavy winter coats and a few bags on it too. I didnt fit wheels as I dont need to move it around but Im well impressed. Favorite thing- no screws. Click click and its all done!
