Office Chair Replacement Parts-28'' Heavy Duty Base Replacement(2200Lbs) - Desk Chair Reinforced Metal Leg,Universal Caster and Gas Cylinder Size

I spent good money on a secondhand HumanScale Liberty chair in 2021, and when its base began to fail, I was really upset. I didn’t want to replace the whole chair just because of a broken base. When I saw this, I thought I’d give it a try since it would be a lot cheaper than replacing the whole chair.This base is awesome. Getting the old base off was a whole thing, but the new base went on like a champ. The old casters fit great, and it feels super strong. I’m a large person, so I needed a base that could handle weight. This thing is the real deal. I should have gotten this strong metal base at the start!

tres tres bien merci

Compre una Steelcase Leap V2 usada que desafortunadamente llego rota de la base haciendo que la llanta se cayera frecuentemente, tras varios intentos fallidos de reparar la parte rota opte por comprar esta base.La base quedo muy bien y se siente de buena calidad me preocupaba que el pistón chocara con el piso pero no es el caso, las llantas originales de mi silla también le quedaron bien, así que en general estoy muy satisfecho.

I can't recommend. Rated for up to 220lbs (100kg), I weigh 200lbs and it seems that my weight was sufficient to ruin this base in less than 4 months of use.

I bought this to replace a plastic base that cracked under use. That base was rated at 300lbs, but to be fair it was often overloaded with kids and wife piling on top of me while I was in the chair. This base is made of STEEL and rated over 2000lbs so should be up to task without me spoiling their fun. The base was easy to put together in 5 min using the supplied Allen wrench. The standard wheel openings are a bit tight however and prevented seating my wheels just using hand pressure. I had to use a rubber mallet to assist in seating them. One whack per wheel was all it took. Very satisfied with this product. Note, the dimensions on Amazon say it's 28" diameter. It is really 26". Typo? 26" is standard and the same as the base it replaced. EXTRA: I see a lot of people here had a problem getting the old base off. So did I initially. I first tried banging it off with a mallet while rotating the base. No good. I then simply went medieval on it and pulled out a 4" angle grinder with a cutting wheel on it. That made VERY short work of it. 5 min in fact. Just be careful not to hit the piston.
