I have 8 sets of dumbbells, 8lbs to 40 lbs, and needed a more efficient way to store them. This dumbbell rack came promptly in the mail, was simple to put together, and is so far perfectly sturdy. It also takes up no room at all. I tried at first putting my 15's to 40's on the rack, but the larger dumbbells sat on top of each other too close, not allowing enough space to take them in and out of their holders without running into the dumbbells above them. So, I put the 8's to 30's on instead, and those fit perfectly. The rack looks great in my garage and is a much more efficient way of storing my dumbbells than the floor.
