Great customer service!

When my cylinder failed, I was in limbo. This Oasis Chair is my abosulety the best chair ever. I have had it for two years. I contacted The Office Oasis to see if my chair was under any kind of warranty. Although they took no time at all, responding to me, I was hasty and went ahead and ordered and paid for the cylinder with extra pay for a fast delivery. I have to have this chair and this one only.
Long story short, my chair is back to normal with a new cylinder and was refunded the money spent in my haste as it is under warranty.
My husband had it replaced in no more than 15 minutes at the most.
Thank you to the friendly and informative staff at The Office Oasis.

Saved A Lot Of Money

When the 2005 Aeron "crashed" to the floor a few days ago (cylinder failure), I just started looking for a whole new Aeron. The price increase over 18 years was astounding! But the chair owed me nothing. I poked around on the 'net and found the Office Oasis videos on YouTube and decided to go that route. Very glad I did.

A few days later, the cylinder (and new wheels) arrived. In less than 20 minutes, the chair is back in service.

(Naturally, the service life of the new cylinder is yet to be determined.)

Thanks, guys and gals! Some of the saved money went toward an Aeron headrest, needed or not. Everything is lookin' good.

Best tool for the job
