The chairs are very comfortable due to the cantilever structure and the flexibility of the polystyrene. The table has a glass top and hollow tubular legs. It would make a great breakfast or kitchen set.

Condition: 3 Chairs and table are in good - very good vintage condition with some typical age appropriate marking and color variance in the polystyrene. 1 chair has a small piece missing from the side of the seat, but it does not affect the structure and still shows well. The chair could be restored.
