Great Quality
I purchased this replacement part because the tilt control mechanism on my office chair had gradually bent over regular use, leading to a concerningly unstable and unsafe seating experience. I was so pleased to discover this replacement, as it is demonstrably more robust and well-engineered than the original component. I was especially impressed by the noticeably thicker gauge of metal used in its construction, contributing to an overall improvement in quality that is immediately apparent. In my opinion, this replacement part represents excellent value for money, and I enthusiastically recommend it to anyone seeking a dependable and long-lasting solution for chair repairs.

Very sturdy
I bought this because I bought 3 gaming chairs a few years ago, and 2 of them boke the mechanism before one year. The seller sent replacements for those 2, but they were the same low quality mechanisms thar will probably break again. My 3rd chair that I use finally broke a few weeks ago, so I decided to get this heavy duty mechanism. I am very happy with it, because it is ay least twice as heavy as my old broken mechanism was. It installed easily. The only problem I have is that my chair had a pull out footrest that I can't put on right now, because when it is pushed in it will now go all the way in due to it hitting the adjustment lever. The old mechanism had a lever that was bent downward, and this one is straight. I may try to bend the lever a little, but it is thick, so it may not bend easily. This is not a fault of the mechanism. It was just not designed for a chair with a pullout footrest.

Excellent replacement that fit perfectly and went on in minutes.
My 20-year-old Bombay office chair was leaning badly to the point it could not be used. I was told by 3 different repairman it could not be fixed. I found this replacement and it went on in 2 mins and the chair is like brand new.

It is heavy duty
Very good . Heavy and strong. Tilt adjustment works very smoothly and easily with a large range of adjustment. Wife was able to get the spring adjusted so she could tilt her office chair back to suit her. Highly recommended.

Excellent upgrade and meets stated specifications
This item is as described. It is definitely an upgrade from the original tilt swivel mechanism which had a weld seam failure. It meets the specs described. Item does not come with screws, so save your old ones to install.

ROCK SOLID MOUNT!!!
Measure carefully. This chair mount is a BEAST.. The construction is impressive. It is ROCK SOLID. However due to my own incompetence I did not measure correctly for my wife's chair. Yes, she laughed. If this will fit your chair, I highly recommend this mount. By it's construction, I would say it would out last several office chairs.

It was good at first
After about six months a weld or something has given way. It is fine when I have the lever keeping the chair up, but if I let the lever out and lean back one side has started leaning back quite a bit more than the other side. I seldom lean it back anymore, but when I do I make sure I am careful so I do not fall over.

Very good product
The thickness of the metal is greater than the previous one that I had, this makes it stronger and more durable
