I am fairly certain that that table and chairs are not from the Sculptra line. It's a great set either way.
I was iffy about them, but they're got the right shape and I've seen other Broyhill furniture where they manufactured it with wicker in place of solid wood; Brasilia chairs specifically, which makes them not as pretty. I think that's what's going on with the chairs. I'd definitely check for a makers mark if I was going to pick them up though.
