Isn't the point of a coat hanger to hang your clothes uncrumpled? If you're compromising on that aspect, wouldn't wall hooks fit most use cases?
For places where space is at a premium a normal coat hanger on a telescopic rod would be a viable alternative in many cases, i.e. have the clothes rotate almost 90°, and mostly overlap.
There's surely good niche use cases for these, but looking at this advertisment I don't see why I'd want to go for this particular solution.
The sales pitch would be more convincing if it was contrasted to other space saving clothes hanging techniques in existing use, rather than pointing out that the inventor was unable to find prior art for her particular solution.

You can also stack the coat hangers vertically, e.g. with cheap plastic brackets like these: https://a.aliexpress.com/_Ew6YWEt
