Seat pan for a size B chair which is the medium size chair. Does not include mesh. Have many available so ask for bulk pricing if you need many.
These are high quality and garanteed perfect fit. I use this myself when I refurbish a chair with a broken seat pan. If you  are interested in buying bulk please contact me for wholesale pricing.
