Customers say
Customers find the repair kit works well on Herman Miller chairs and is super simple to install, taking just 5 minutes to complete. Moreover, the parts are well-made and customers consider it good value for money. However, the fit receives mixed feedback, with some saying it’s perfect while others report it doesn’t match their chair. Additionally, the bearing durability is a concern as several customers report it breaking during installation, and the noise level also gets mixed reviews, with some customers reporting popping and squeak-free results while others experience creaking noises.
