It broke along that weld within a couple months of owning the chair.

I have purchased 2 of these and they have both broken the same Lastway, the weld holding the seat has broken in both cases.

A major problem is the weak welding for the pneumatic seat height adjustment

Junk, bought 4 of them and after 2 months they are almost all broken, the welds under the chair support all bend and break

Over time the weld will start to break and ultimately making it impossible not swaying side to side ( which shouldn't happen )

The welds holding the seat bottom bracket broke

4 amateur spot welds hold the center part of the stand and all broke off from the center within 2 months of regular usage

I must have received a bad one with a bad weld?

The welds holding the seat bottom bracket broke

The welds broke that connects the chair.
