The kit was a complete package with easy to follow instructions and easy to use parts. Well worth the money. The chair is operating like new. Thank you for your product!!!

Perfect Replacement for Herman Miller Aeron

By Ben N.

Just wanted to say how impressed I am with this product – I have now been able to remove the old cylinders from 4 Aeron Chairs that had been firmly stuck in place after 15 years of constant use and have defeated several previous attempts to be replaced – your replacement tool made a difficult job very easy.

Easy Removal, Even Easier Installation

Shannon T.

The removal tool was a huge selling point for me. I was stuck (literally) on removing the old cylinder from the base of the seat.

The removal tool worked like a charm and I’m back in my comfy chair again. As a tip – use two wrenches at the same time on the nuts that push the rings apart – makes things go smoother.

Great fix

The replacement works great. When I had installed I missed a step and left the cap on the hydraulic cylinder. So it was not working. Contacted them and they replied back and let me know what the issues might be. Was able to get the cap off and it works great. Will pay better attention next time. Thanks for all of your help.

Excellent Product & Service

This was so easy. The price was right. Ordered the product, shipped immediately, delivered on time, precise simple instructions including the proper tools to get the job done. New chair gas lift was easy to install and works better than the original. The icing on the cake is the guarantee that it will fit your chair or your money is refunded. Exceptional 6 year warranty. Doesn't get any better.
