What are the best-built popular high end furniture brands?  

Well
For starters, except for DWR, none of these are really "high-end" furniture brands. I believe DWR oversees manufacturing for a few of their catalog items, but I can't speak to the quality.
Herman Miller and Knoll are good quality. Personally, I don't have much experience with truly "high-end" residential furniture. I'm sure others on the forum do though.

CB2's prices sure do feel high end to me. But what do I know. I'm just a kid.

??
Is "high end" furniture determined by price, or quality??
just curious,

Can't really speak to their furniture, but they have some nice/cool accessories. Again, not exactly high-end though.

Dear HouseKebab
The experts will correct me, but I'd concentrate on fundamentals, the way John Wooden used to teach basketball, because there isn't a Consumer Reports for mcm furniture.
Beauty, function, and durability are the criteria I'm referring to, with function the most important.
I wanted to give you an example:
I bought a Herman Miller Palisander molded wood chair, which is a new design. It's one of the most beautiful wood chairs I've seen. I know someone who works at one of the companies already mentioned, and she had told me she was drooling over it.
Costly mistake.
I then found a thread on here I had discounted because the chair wasn't even out at the time (they were just analyzing a photo).
I was amazed how accurate the thread was.

this is easy
HouseKebab,
Everything you mentioned would never be considered "high end". Try the Luminaire site for help with this question.

For regular,
every day high end, I like Roche Bobois. Nothing on your list is high end, in my opinion. More like Target with delusions of grandeur.

.
I too, like Roche Bobois, b&b italia, and decent vodka.
Blessed and bloated,

Gave all of our
male relatives Swiss vodka this year for holiday gifts from our one and only vodka/gin distillery in the country. Don't actually know if the glacier water used in the recipe makes a difference but I was voted best gift-giver this Christmas, Aunt Mark. The packaging is also cool.

Why those lucky boys!
Jesus would be proud.

Mainstays
only at Walmart

DWR is definitely at the top...
DWR is definitely at the top of the list, but I disagree with others that Crate and Barrel isn't high end.
*puts flame suit on*
I will say that most of their products and more notably most of their recent products are certainly not high end, but much of the hand crafted, Made in USA stuff are high end in my opinion. I have a solid walnut compact office desk constructed with interlocking / dovetail joinery and a walnut bookcase that weighs about 300 lbs at least. These are really the only two products of C&B that I can speak of, but they are very well constructed and beautiful pieces of furniture in my opinion.

High-End
Certainly "high-end" can mean different things, but generally for consumer products (including furniture), it refers to brands that are at the upper echelon of pricing, presumably due to their pedigree of quality of materials, craftsmanship, innovation, design, durability, customer service, etc. In this regard, Crate & Barrel along with the others really aren't high-end brands at all.
Certainly well-made things can be purchased at prices that are affordable to most.

Yea yea, it's not "high end"...
Yea yea, it's not "high end" like $59,000 sofa.
That's why I used "popular" in the title.
Allow me to rephrase the question for the Aspies in the house:
What shitty mass market tres gauche design wanna-be poser brand (that is significantly more expensive than Target and Walmart) is the best built?
Design within Reach?
Restoration Hardware?
Crate and Barrel?
Pottery Barn?
West Elm?
Can you rank them Best to worst?
