My 8yr old has a standard 6'x2' reach-in closet. We need to redo the shelving (currently Closetmaid cubes that were there when we bought the house, and nothing stores well in cubes!). I like the flexibility of the Rubbermaid Fast Track system to grow with the child but have had nothing but trouble with wire shelving in the past. Is there a system with that flexibility but wood shelves? Or other options I am not aware of?
