Mid Century Dining Set Chairs & Table Please Help With Any Info

Honestly, that looks EXACTLY like a dining set IKEA used to & maybe still does make(haven't really looked at a catalog of theirs in some time.)

Are they saying it's just MCM style, or are they claiming it's actually a MCM piece from the period?

How much do they want for it? I'd check on IKEA's site if they're still carrying that dining set, price it out new there & if it is indeed an IKEA piece let them know you're aware of that. I personally wouldn't buy used IKEA furniture just cause brand-new isn't a huge monetary investment at all.
