The new base came quickly and was very easy to replace with the given instructions included in the box AND emailed to me! Thank You for such a great product saving a chair I've had for years and making it BETTER than it was!

Great product! Came in on time and is so far superior to the base that came with my chair. Strong and very lightweight.

After 2 months of use this item broke... Very frustrating, it seemed to be a quality product and just snapped. Update: I contacted them and they are sending me a replacement. That process hasn't been a problem. I will go through the difficulty of installing it again and hopefully it lasts longer this time. Revising my rating based on their service.

A perfect fit for my chair, to replace the previous plastic base that failed after 1 year and 4 days of use (so no manufacturer warranty). Very happy with the quality, and knowing it won't fail and dump me out of my chair like the stock base.
