Heavy Duty 500LBs Office Chair Tilt Control Mechanism Replacement Parts, Office Chair Swivel Tilt Base W/6" x 10.2" Mounting Holes - Black

I bought my office chair at Sam's Club in 2018 for $213.98 tax included. The chair base was squeaking and one day it started leaning more than usual. Upon inspecting it I found several really long cracks in the base plate. So I went searching for a new chair and could not find what I wanted at a decent price. I found this base rated for 500 lbs though my old chair was only rated for 350 lbs. The four mounting holes on my chair matched this plate so I made the purchase. I wouldn't say this was necessarily an easy replacement mainly due to the troubles I had with removing the old piston from the cracked base. I ended up having to use a grinder and hacksaw to finally expose the end of the piston so I could pound it out using a deep well socket and a hammer. There may have been an easier way to do this so check Youtube. I just did not know what old parts were needed for the final fix. Not sure why La-Z-Boy used all those cables when this simple design handles it all. If you don't want to deal with removing the piston my suggestion is to purchase a new one. However you will still have to get the old piston out of the swivel wheel base.My chair no longer squeaks! The single lever activates both the piston and locks or unlocks the seat back. The chair feels way more solid. This chair was suppose to have a 10 year warranty but this repair was far easier to deal with in my opinion and it's way sturdier than the original base.

My last chair base didn't make 60 days before starting to wear out and become unstable. It was rated for 400lbs. I'm nowhere near that (bigger than average, but not that big). Got this to replace that one. This is much better than your "standard" base. The sheet metal is at least 3x as thick and all parts look like they'll last a long time. After watching a video to remove the existing gas piston, it was easy to install.

This part fit perfectly on the chair I purchased from Amazon 2 years ago. That chair base was cracked 3/4ths of the way around the piston mount hole and was getting dangerous. This replacement is heavier duty than the original.

I had to purchase this to replace the one on my chair that had bent causing the chair seat to lean. this one is a lot heavy duty, thicker metal, and higher quality then the one that came with the chair. it's definitely worth the money.

I used on a chair that the unit had broken down. This one is heavier metal than the one that came onthe chair.

The metal on this is almost twice as thick as my old/broken one. It weighs a lot more than the old one as well.The tilt adjustment is easy to reach and is very smooth. My old one always was temperamental. The tilt bar itself is larger in diameter than my old one. The old one would occasionally flex a bit when using it, this one is SOLID!Now if they can only make hydraulic chair cylinders as heavy duty!

heavy duty and right size

This chair base mechanism is made of the cheapest metal I've ever seen for a chair. I have bought two of these so far and both of them have split in the same exact spot where the spring is, which causes the spring to eventually shoot out the bottom.I do not recommend this brand to anyone. I weigh less than 200 lb, this is rated for 300; it should not break within a month of ordering it. If you do notice a freaking noise or clicking noise, make sure to return it right away so you don't fly backwards when you're leaning back and smack your head on something.
