We have approximately 40-45 library chairs available for free.  Take as few or as many as you could use.  You would just need to come get them.  They measure about 32"H by 19"W by 18"D.  They are in pretty good condition overall, some have reading/library themed stickers on the seats.  Our last day of school is June 7 so we're hoping to get them out of here by then so they don't have to go to the landfill over the summer.
