What company manufactures Pottery Barn's dinning room furniture?  I am
specifically interested in the Dana Dinning Table.

Hello Hartsja-ga,

I contacted Pottery Barn at their Customer Service number
1.888.779.5176 which is operational 7 days a week, 4:00 am - 9:00 pm
(PST).

I asked them about the Dana Dining Table

And they told me that they have their own manufacturing plants all
over the world. Pottery Barn hires designers that design furnature
only for them. They then manufacture these pieces at company factories
all of the world. This specific table is manufactured by Pottery Barn,
at the Vietnam plant. They own the design rights as well.

If this answer requires further explanation, please request
clarification before rating it, and I'll be happy to look into this
further.
