Stokke® Tray is compatible with Stokke® Baby set version “V2” or “V3”.
If there is a mark “V2” or “V3” on the inner side of the Baby set rail (next to the sides attachment), then the Stokke® Tray will be compatible with the Baby set. If there is no mark on the rail the Baby set is version V1 and the Stokke® Tray will unfortunately not fit.
