My aunt and uncle have lived in the same Chicago apartment since the 60’s. Also in that apartment since the 60’s was an amazing walnut tension rod shelving system. I was thrilled when they offered it to me and it now proudly stands in my office. Even though it holds about a ton of books, it still has an amazing visual lightness to it. I can’t tell you how much I love mine. If you want to experience the same joy from something that just performs a simple function, you can buy some from Moss. The great thing about it is that it can be reconfigured if you move or if your needs change.
You can email or call them and tell them what you need and they will come up with a configuration for you. They’ll send you a drawing and a price and your new shelving will arrive fresh from the UK just like you like it.
