We have an old office chair that is pretty sturdy but very uncomfortable. The seat cover has worn off and the cushion was flattened. I was having pain in my tailbone after sitting on this chair for a short while. Instead of throwing it out and buying a brand new one, I decided to reupholster the old office chair. This is what it looked like after most probably 10 years of use. Materials needed: Upholstery fabric: dimensions based on your chair dimensions. Make sure you measure length and width including the height of the seat and add 2 more inches
