It will apply to MOST office chairs...... SADLY, I do NOT know WHY this simple repair kit is available @HOME DEPOT, LOWE'S, WALMART, etc..... they would make a lot of $$$ selling this repair kit!!! So many office chairs have been "junked" due to frustration OF NOT being aware of how VERY EASY is it to "do-it-yourself"...... I went to HOME DEPOT and they had SO MANY retainer clips in all different sizes and shaped but NOT the exact retainer clip for 99% office chairs, in which this repair has! It took me LESS THAN 5 MINUTES to repair my beautiful office chair; I was VERY CLOSE to have my office chair salvaged to a thrift store but THANK GOD for the internet and creative businesses for offering niches for such simplistic but very important pieces to save expensive office chairs! I HOPE I ANSWERED YOUR QUESTION??? ;-) **Q: My piston goes completely through the bottom of my aeron until its touches the floor, does the clip prevent the piston from coming out the lower end?** A: I was having the same problem with my chair and this repair kit fixed the problem. **Q: I need screws for the arms of my furmax office chair will this apply?** A: This kit is for the gas lift cylinder if you still have a screw from the arm and are just missing some id sudjest going to a local hardware store **Q: what is the body weight limit for this product** A: Just my opinion, this kit handles 200 ibs. My chairs are not the large ones made for large people. ## Frequently Bought Together - Replacement Hardware Repair Kit for Office Chair Gas Lift Cylinder - Includes Clip, washers, & Bearing - S4451-K - The Office Oasis Original Rollerblade Office Chair Wheels (As Seen On PBS) - Smooth & Quiet Casters - Safe for Hardwood Floors & Carpet - Easy Installation with Universal Fit - Set of 5 - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/253878526-chairpartsonline-replacement-hardware-repair-kit-for-office-chair-gas-lift](https://www.desertcart.vu/products/253878526-chairpartsonline-replacement-hardware-repair-kit-for-office-chair-gas-lift) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-10*
