Eero Saarinen designed "Tulip" stool for the Knoll Furniture Group in 1956. This aluminum cast stool features a newly covered black grey knit seat.
Eero Saarinen designed the 1956 Tulip collection in terms of its setting, rather than a particular shape stating, "In any design problem, one should seek the solution in terms of the next largest thing...If the problem is a chair, then its solution must be found in the way it relates to the room..." In Tulip, Saarinen realized his ideal of formal unity, "Every significant piece of furniture has a holistic structure."
