Review: Good replacement - desertcart added a flag to this that it is frequently returned because of the size. I used the dimension sheet in the product image listing and that helped me to see that this would have been a perfect fit. As stated by other reviewers, I also purchased a hammer to get the old base off and very easily installed this in a few minutes. Does its job well and fit within my budget (£25). I've seen quite a few reviews talking about the welds having a 2 year life cycle. I guess I'll be back in two years (or less depending) to report my finding.
Review: Fitted xrocker chair - Used this item to fix my sons xrocker chair, was going to buy a full new chair, but decided to try and fix it, bracket £15 v £175 new chair! Absolute win!! Thank you Ps. Put bolts in and then tighten all together once bolts are in place, it may seem the wholes are slightly out, but they are not!

## Questions & Answers

**Q: Are the advertised measures accurate? I measured my old base and it's 180mm x 230mm, wonder if this will fit**
A: The advertised measurements are from centre hole to centre hole, not the edges of the metal.  If you unscrew your old base and just measure between the holes in your chair, you should be better able to tell if this will fit.

**Q: Does this do tilting and raise/lowering in one lever? My current chair has a separate lever for both**
A: Yes it does both actions in one lever, and slides across to lock the chair so it won't tilt.

**Q: Does it fit an jl comfurni racing chair?**
A: No idea but most chairs r generic fitrins so ask seller is all u can do......but id say it will bro

**Q: does this base need gas???**
A: Hi There There are no serviceable parts to this mechanism that I am aware of.I have had this for a while now and it seems to be working fineP.J.

### ⭐⭐⭐⭐ A good affordable option to repairing your chair
*by A***S on 9 October 2025*

BiMi 50137 Replacement Office Chair Tilt & Lock Lever Base Plate Mechanism, Fitted a Corsair T3 rush perfectly. The mechanism is pretty much the same as the one i took off minus a few smaller details. I had to repair a family members chair due to the fact the gas lift cylinder failing and part of the system split the metal so i had to remove the entire cylinder and lift mechanism. Assembly was easy and took a mere few minutes in order to screw the plate onto the chair. There is a slight tilt after the install its minor however, the chair does wobble very slightly. definitely worth the price when repairing a fairly expensive chair. Considering how much Corsair quoted this i felt was a better option and more affordable. Overall fitted perfectly, no modification needed, sturdy and it pretty seemed very similar to the one i took off. Only 4* due to the fact there is a minor wobble other than that its a good affordable option.
