I live near a Pottery Barn outlet and have seen a lot of furniture for sale there over the past few years, many pieces which have been pretty banged up. I have to say that I am not impressed by their wooden painted furniture. It seems to be damaged pretty easily and underneath the paint, the wood is not a high quality. I would never use this type of furniture in a child's room. I don't think it would hold up well where it got a lot of use.
I don't know how well made their upholstered furniture is.
Their accessories, such as lamps, candlesticks, etc. are nice and seem to be well made.
