We have owned a couple of Knoll office chairs for about 15 years. The leather on the seat base and mesh material on the back still look new, even after tons of use in our home office over the last few years. The only issues have been the armpads which cracked and more recently the seat base which also got cracked. I assumed that this meant having to replace the chairs. Enter Office Replacement Parts (ORP) which I found on the internet and which carried the OEM parts for my chairs. The first purchase of the armpads for one chair went seamlessly. Order placed, next day the armpads were on their way and I received them a few days later. All with automated notifications coming my way to keep me informed. Best - the armpads were easy to install. A year later, I ordered another set - for the other office chair. Same great experience with ORP. Now I decided to look at the seat base which seems like it moved more than it should - turns out it was cracked pretty badly and though the other chair did not seem to be broken, I looked at it and it was also beginning to crack. A replacement of these seemed more daunting but I decided to see if the part, which at the time I did not know what it was called, could be found on the ORP site. Lo and behold, it was there with a great photo of it which is not always the case. I had a question on a Saturday about it - wrote to ORP and on Sunday received a response. I was still a bit unsure about installing this myself and asked if there were any instructions ORP could provide. Another immediate email back with office Knoll instructions. And it looked like a pretty easy install. Ordered the seat bases - they arrived as planned. And the installation was actually really easy. All thanks to ORP. If you are wondering if you have found the right place to order replacement parts for your office equipment, you have. ORP will take great care of you. read more
