Premium chair for sale (New $1395) - selling used one for $600

Hi, I'm selling a premium chair that helped a lot with my health reducing back pain caused by sitting several hours in front of the computer. New is worth $1400, but I'm selling mine for $600 - a chair in perfect condition. To be picked up from EVGR.
