Even living in a good sized 1br with two people, the closets couldn't hold both our wardrobes. I bought this rack because it uses up vertical space rather than horizontal living space.We had a cheaper rack (from a certain swedish furniture store) which wobbled dangerously everytime we touched it. So, we upgraded to this double rail z rackBest. Decision. Ever.It seemed wobbly at first but the weight of the clothes seem to have weighted it in place. The wheels are smooth and don't get caught on the carpet, and I can easily move it around with one hand, even with both rails full.The only complaint I had were the insturctions that came with were badly photocopied, and I had to puzzle through some of the assembly.
