    • Sturdy, perfect fit, and easy to install
Size: 10.15" x 500LBS
Last time I bought a heavy-duty tilt mechanism, it lasted a couple years like the original one (I'm 220lbs, near-daily office use). When this one arrived the beefyness was obvious; this uses MUCH thicker steel, thte welds are good, the points of reinforcement are obvious, and has a bit more resistance when I tilt back. It fit the hole pattern perfectly, and was a cinch to install (or maybe I'm getting used to doing this). I do miss that this one isn't as easy to tilt back lazily so I can slouch as I did before, but maybe I'll have better posture now. I'm confident I won't have to replace this one. ... show more

    • Saved my DXRacer!
Size: 10.15" x 300LBS
I bought this to replace the broken one on my DXRacer Gaming Chair. It fit perfectly, very sturdy and works very well. Easy to install, great value. Much better option than buying a whole new chair!

    • Way better quality than the original that came with my chair...
Size: 10.15" x 500LBS
I purchased the 500lbs version of this tilt mechanism for my chair when the original broke when I wasn't paying attention and leaning too far back in it. SNAP! This one is way better quality than the original that came with my chair. It feels like it was built for a tank. My old one was flimsy piece of junk. This may be a bit overkill, but at least I know it is good quality and will last forever. I'm impressed with the hefty weight and construction of it. They didn't cheap out here on this product. Completely worth it. There's no way this thing is going break. Pay the extra, and get the 500 lb version. Chances are, you will never have to worry about replacing it again, unless there is a Richter scale level 10 earthquake or a dinosaur-sized 120 mile diameter meteor falls on your house. I felt like a weight lifter putting this on my chair, as it's pretty heavy. The weight is good thing, though. It's solid. I'm glad I bought this! ... show more

    • No lies, definitely stronger than stock
Size: 10.15" x 500LBS
Bought this to repair a fairly high-end chair from over a decade ago. I had to modify the front holes a TINY bit because my chair is nonstandard, but close enough that it works flawlessly. Due to over a decade of use, the gas cylinder was utterly stuck, so I had to replace both. None the less, the metal on this assembly is considerably thicker than even the high-quality decade-old assembly, and I strongly suspect this chair will last another ten years, even if its original cushion won't. UPDATE: I've been ignoring a really annoying issue for over a year and only now realized, the entire time I had forgotten it was an aftermarket part, I was assuming the annoyance was related to the original chair itself. The locking bar which limits the seat tilt slips out and unlocks. Constantly. It had since probably a year after I bought it, maybe earlier. I really am removing an entire star for that -- it would have been SO EASY to implement ANY form of retension for that lever, and it would have made the product otherwise flawless. ... show more

    • Awesome and worked!
Size: 10.15" x 300LBS
My gaming chair that I absolutely love had it's old base literally split off and was tilting forward sliding me out of the chair. I wasn't any near or over the the weight limit. I bought this in hopes to fix my chair. It worked like a charm, is better quality than the old one that came with the chair, and was extremely easy to install! Been using it over a year now and no problem. :) ... show more

    • Seemed Good at first, Broke after 4 months.

I Bought this as a part to fix a gaming chair that I had purchased as the weld had cracked, causing the chair to sit off center, leading to back pain. After installing this on the chair, all went well and easy. This was until the chair became of center. After inspection, it was found the welds had cracked again. For reference, I am only 235lbs and should be within the limit of this devices operating capacity. Might be good if you are under 150lbs, but I would not trust it. ... show more

    • Very sturdy and well constructed NOT the size they claim
Size: 8.6" x 300LBS
This seems to be of very high quality, very hefty far better than the org Walmart one that came with the chair and broke(started leaning) with less than a month of use however they ARE NOT the size they claim nor was it a error in that they sent me the wrong one these are NOT 5.9'' x 8.6" they are 5.9'' x 9" so unless you can drill your own holes or need that size dont order That said my star ratings are based on the fact I had to drill new holes and it took me trying different things before it would work, its harder than it sounds to drill new holes the wood is so easy to disaggregate in my chair I had to use epoxy to create homemade rivets like the org bolts go into so the false advertising and the fact I had to drill new holes make me personally rate it low however it should be noted assuming it will fit your chair its a VERY high quality product I just wish they didnt claim it was 8.6in when its really 9in ... show more
