Try Crate and Barrel, I've always felt it is just Ikea at a higher price + quality. I suspect the price increase is greater than the increase in quality though.
The designs from Crate and Barrel usually aren't as good as those Ikea, even if the quality is up to snuff. CB2 is usually okay, as long as they haven't decided to make the piece you want only available in bright orange or something. They do that sometimes.
There is definitely a gulf between Ikea (bad quality, good design, $) and DWR-tier places (good quality, good design, $$$$). Muji maybe, if they happen to make something in the niche you're looking for.
I love the irony of naming yourself "Design Within Reach", while still being out of reach for most people who aren't professionals.
As the owner of several Muji items (trash cans, silverware holders, rolling storage unit, coasters, dish rack), I have to say while they look nice, they're rarely as well thought-out as Ikea. The trash cans don't seal, and the dish rack can't actually hold plates upright in position.
I can't praise enough the quality and functionality of Joseph Joseph items. It seems like everything I own from them meets the advertised functionality and then some. And while expensive, the prices are fair. Great plastics and finishing.
