Review: El pedido vino rápido y se ve de buena calidad, casi como el de fábrica, compré una Aeron Classic de segunda mano y amé la silla pero el pistón definitivamente necesitaba cambio (se bajaba cuando me sentaba y seguía bajando con el tiempo), intenté ajustar el tornillo que viene en la parte de abajo según lo que vi en youtube pensando que eso lo solucionaría pero no funcionó. El proceso para cambiar el pistón no fué nada fácil, tardé unas 2 horas entre que veía comentarios en reddit de como remover el pistón más facil, videos y demás, al final lo que hice fué: - Usé una pinza stilson (pipe wrench en inglés) de 12", pensando que era pequeña, un martillo y algo de WD-40 - Lubriqué tanto la base por los dos lados como la parte que va ensamblada hacia la silla. - Acosté la silla horizontalmente sobre el piso, ajusté bien la llave al cilindro volteando en posición contraria a las manecillas del reloj - Con casi todo mi cuerpo y mis brazos sostuve el respaldo y me paré sobre la pinza stilson, después de 2 brinquitos (peso 100kg) se aflojó después de estar batallando como 2 horas. - Para sacar la base, tal y como se ve en varios videos, sostienes las patas con una mano y le das durísimo con un martillo al cilindro, salió como de 5 madrazos. - Para instalar el repuesto solo puse la silla de cabeza, inserté el cilindro y presione la palanca para ver si se activaba - Cuando se activó, le coloqué la base y puse ya toda la silla en posición normal Todo bien hasta ahora, la verdad pensé que iba a tener que batallar más pero si se pudo, si algo falla con el cilindro volveré para editar la reseña, ya no se baja la silla ni al sentarse ni al paso del tiempo, una mejora total y en mi opinión tiene un poquito más de altura que el cilindro de fábrica.
Review: Works as advertised. Fits the Classic Aeron. Zero complaints. Very satisfied with this purchase. Instructions: You’ll need a hammer, wd40 or a penetrating oil, and an 11/16 socket. Optional: patience, swear jar. 1. First remove the seat. (Use a hex key/Allen wrench). 2. Prepare to remove the wheel base by applying degreaser/wd40 to the points where the cylinder is attached. 3. Wrap a towel around wheel base and gently use a mallet to knock it loose/off. 4. Remove the the plastic hardware lid by gently prying it open. Place aside. 5. Use a philips screwdriver, to remove the two screws holding the pneumatic lever. 6. Place chair at an angle over a bench or chair. (Pneumatic cylinder facing down at an angle.) 7. Place an 11/16 socket on top of where you removed the pneumatic lever lid. (From Step 5. The removed lever lid reveals the hole where the pneumatic cylinder is affixed.) 8. Whack the hell out of the 11/16 socket with a hammer. If it is properly degreased, it will shoot right out. 9. Attach the new cylinder to the wheel base. 10. Place chair on top of cylinder and wheel base. 11. Replace the two screws from step 5. Adjust the screw that sits on top of the new cylinder. The height/position of this screw will either increase or decrease the rate at which the chair goes up and down. 12. Repeat steps to re-assemble. (This point is a great time to deep clean the chair). 13. ???? 14. Profit :)

**Q: Does this work on a side activated or front activated Aeron chair or both?**
A: It definitely worked on my chair with the lever on the side. I am not sure about front activated chairs.

**Q: Might someone please tell me after installing the new cylinder, when it is in its LOWEST position, how high is the seat from the floor?  Thank you.**
A: That will vary by the model and size of your chair. I have the original (2000s-era) Aeron size C and when fully lowered the top of the seat is about 16" from the floor.
