Mastery Mart Office Chair Base Replacement, 28 Inch Heavy Duty(2500 Lbs) Metal Leg, Reinforced to Repair Swivel Gaming Chair Bottom Part with Universal Caster and Gas Cylinder Size (Silver)

An office chair that i purchased on Amazon had broken and I wanted to replace it, looked online and found a sturdier base for this chair. Bought it and it looks good.

Excellent product!! Made my chair feel so comfortable and stable!

1 year in and it's been absolutely perfect, I recommend this lots

Fine, except for one thing, namely it takes the bottom of the lift tube a couple of inches higher than a typical base. For me 5-8" it was unfortunate. Also be aware that returning a tube, base or chair bracket for a refund is a bit iffy since the tube is just pressure fit into both the base and bracket. Getting it loose from either end, especially without scratching or otherwise marring the tube, base or bracket isn't easy.

I had one my chair that broke so I ordered this instead of replacing the entire chair. Worked great

All metal, I had to replace a "metal" and plastic one that came with my office chair, but I swapped the caster wheels out for rollerblade style and the sockets that hole the wheel stems started to break and one broke completely, I did not realize they were all cracked until I got the old one off, but this has metal sockets and the stem of wheel fit completely inside. So much better design. It is a bit taller higher than my old one but it's workable. easy to put together. It's a good replacement if you need one.

Good quality base. Assembly is straight forward and had my chair back up and working in less than 5 minutes. Bought this to replace the factory plastic base my chair came with which was starting to crack. Turns out this is a more robust and stronger base than I had. It did add about an inch of height to my chair but not an issue since the chair is adjustable. Easy assembly, works as described and added strength.

Began to fail after only a few months. Metal cracked. If you have a remote job that requires you to sit 8+ hours a day, stay away, this will fail. Also the pictures are deceptive, it's not one solid piece. It's made up of a bunch of pieces that you assemble and bolt together, tons of points of failure.
