Couldn't be happier!

Ordered Friday afternoon. It was sitting at my office door monday morning. Everything worked as expected on my Steelcase chair. Great value. Thank you.

Replaced our Big and Talls chair cylinder just fine

Goes up and down and we'll see how well it holds up as our chair is in pretty good condition and this was the 3rd time a cylinder was replaced as replacement #2 was a warranty replacement with the same part.

Office chair cylinder replacement

The cylinder in my special order office chair failed. I first went to the office supply store where the chair was ordered. They were no help, suggested I contact the manufacturer, who is in China. Then I found Office Oasis. I was pleasantly surprised at how reasonalbly priced the cylinder was. I needed a little help while installing was amazed at how great is their customer service. They showed a genuine interest in helping. Most refreshing.

You Saved my 20yr old Aeron Chair

The pneumatic cyliner on the Aeron chair I've been using for 20yrs finally gave out and I was doubtful I could repair it myself. Thankfully I found some reviews of the kit sold by The Office Oasis and a super helpful video the company posts. My kit arrived in 2 days and I was able to fix my chair by following the video and instructions. Highly recommend it and the company.
