This listing is for 8 Brand new Replacement Seat Pans for Herman Miller Classic Aeron, size C (3 dots) w/ foam insert. This is not an OEM, it is an aftermarket and the weight limit is 300 lbs just like the original. Seat pan for a size C chair which is the largest 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.
