MySit Heavy Duty 300 LBs Office Chair Tilt Mechanism Replacement Parts, 5.9'' x 10.15" Mounting Holes Tilt Control Mechanism

My relatively new swivel chair started to tilt quite badly to the right. I paid a few hundred pounds for it and the top is still like new so I was really disappointed. However seeing this replacement part I decided to try fixing it. As you can see the weld on the original part had broken half way round so I suspect this was causing the lean. The hardest part of switching the base attachments was getting the gas lift cylinder out of the old. i ended up using a pipe wrench and a hammer! All is fixed now and the chair feels sturdier than it ever has before. Hopefully this will last many years!

I have an X-Rocker Alpha chair and this fits well and is a great upgrade over the stock one that comes with the chair. Would suggest this if you find like I did that the original one breaks with all the rocking back and forward.I went for the heavy duty which should be more than enough for me and the chair.

My own chair lift mechanism cracked - searched for a replacement and found this one - as other users described its solid - heavy metal 4-5mm - added new life to my office chair, very happy with the purchase and would definitely recommend

Got a £500 odd gaming chair which broke so replaced it with this part 👌 for £500 odd it should of had this on it in the first place.This was 3 x thicker than my original.

Exactly right replacement

Much better quality than the other companies. This has really thick metal. Unfortunately have to return it as it doesn’t fit my chair because different holes but definitely recommend.

i be wait for my part so i can fix my chair but it has not come like it say ?

Much stronger than the original one with 4mm thick steel opposed to the 2.5mm steel that was splitting.
