As much as Ikea served me well for a period of my life (with some pieces continuing to do so), I wonder what has prevented designers of different styles from copying Ikea's model, which clearly works and scales. I know it isn't that easy, but I feel like there's a gap in the market between say...Ikea, and what I typically consider "mid to high end" Crate & Barrel/West Elm/Pottery Barn/Ethan Allen.

Ikea gets a lot of things right, but if you don't like their aesthetic, you're pretty much out of luck finding something of similar quality for that price point.
