Structube has some nice looking stuff, but the quality is really poor, at least with the dining room chairs i bought...really really bad - flimsy ikea stuff would be light years better
We got some of their dining room chairs awhile back and returned them twice over. Base of the chairs was wood but all had a hairline crack in them. Returned, got another set and same thing. Wife really liked the design but didn't want them snapping on me a year later and be shit out of luck.
I do like their stuff in general though. We got our sectional from Urban barn for the basement and den sofa was from Ikea.
