These chairs looks like a generic design from IKEA (or clones by others). It is useful and that is all where the value is.
If collecting IKEA stuff is one's passion, start with the designs of Dutch designer Hela Jongerius for IKEA PS or the classic mid 1950s Lovacken table reissued a few years back or some of the re-issued Marimekko textiles.

IKEA also sold a high quality print of Robert Indiana's iconic 'love' poster, one of the two surviving IKEA stuff I still own.
