I got rid of my Aeron and got these instead. Excellent condition. No stains, tears, or smells. All the usual adjustments plus a lever which slides the seat forward and back, like a car seat, for leg length -- awesome for people with short legs! Retail is about $600 each. Selling the pair for $300. Serious inquiries only, please -- they are in storage. Feel free to text at the number below. Thank you! - - - Denise Caruso denisecaruso@mac.com +1 415 730-3562
