Mirra 1 Gas Lift / Pneumatic Cylinder

Stops the slow sink — your chair holds its height again.

Fits: Herman Miller Mirra 1.

DIY fit in about 15 minutes with a rubber mallet and pliers — or we'll fit it for you on a London visit.

Don't replace the whole chair over a worn cylinder — this is the part that fails. Plain-English fitting instructions included with every order.
