We had an expensive high quality 'stalk with movable swing out rails on a weighted stand' unit for years until it finally got damaged. I was unable to find anything similar with the weight and sturdyness with which to replace it.
I looked across the market and this was the best option. It wasn't the high quality that I wanted, but it looks OK and holds two thick bath sheets folded and a hand towel folded. It was easy to put together and quite a cheap price. I doubt we will be using this one for twenty years however.
