The real price of anything you see on 1stdibs is about 40-50 percent lower than what you see. Their fees are egregious and if a piece is unique or the seller name has enough info it's almost always very easy to find the seller and contact them directly via instagram. Also, if you want more market price information go look at sold prices on liveauctioneers (just keep in mind buyers premium is about 25-30 percent)
Yep, agreed. I don't really understand why 1stdibs even exists, since I can't imagine anyone ever pays these prices. Chairing and Pamono (now owned by Chairish) also is generally inflated.
My go to sources are Selency, Vntg, Instagram, Catawiki, and then a bunch of online stores across Europe I've bookmarked, including auction sites like Bukowskis in Sweden. The smaller vintage stores are the ones to go to generally.
