The wheel socket broke after only 6 months of use. From the photo, it is clear that the support point was welded very poorly, as the welding exists only in two small spots instead of adequately covering the entire joint.

Poor quality. When installing the shock absorber, the ring bent, making both the shock absorber and the legs useless. The store refused the return with the excuse that the factory that supplies them does not make mistakes.

Much more durable base than the usual plastic ones that office chairs have. It also makes it easier to replace a worn shock absorber.

For the money it costs, it is quite a sturdy construction, I don't know about long-term use of course but for 2 months now it hasn't had any issues.

Used on a Cooler Master Caliber R1 Gaming chair. I have had it for about a month and it has not shown any problems. I should point out that on my chair, the height increased a lot, so take that into account. An alternative is to remove the wheels (as long as there is no carpet or if there is parquet, tiles, etc.) and replace them with adhesive furniture protectors.

In conclusion, it seems to be a sturdy construction, and for me, being close to 110 kilos, it holds me well.

I have the Douxlife GC-RC03 (3rd photo). The wheels fit normally. When I first placed the chair on the base, it wobbled a bit back and forth, but after I sat on it and it was pressed down, after a while it settled into its position properly. I don't know if they sent me a different base because in the photos the center looked more reinforced and the plastic piece didn't show (which is purely like a shell and if you want, you can remove it and inside is all metal). Overall, it seems okay, time will tell. The 4 stars because I expected the product from the photo.

Extremely stable, much better than the plastic ones that the chair originally had. And it is indeed high, it will definitely raise your chair in height!

Perfect metal base of better quality than the chair had, fits properly on the chair and appears sturdy

It seems very good and stable, the size is standard, it fit perfectly. I think the hole is 5cm and the hole for the wheels is 1cm. I don't know about the lifespan yet.

*Update: 28/1/2025 no problems (and I was 140 kg, now 110)

I replaced the corresponding plastic parts of my office chair (which broke after a year of use) and I am very satisfied as I didn't have to throw away my chair. Very durable, with daily hours of use by a person weighing over 100 kilograms.

Applied fine and the pre-existing wheels fit fine. 2 months of daily use, overweight and everything is good. Due to the downward curve of the legs, the chair has raised quite a bit and now I use it at the lowest level but everything is good.

So far, it appears sturdy, durable, and well-made. It is metallic and heavy, so it performs its job well.
