I ordered this chain to repair another item I bought from Revain. Bought a computer chair. After a few months, the back of the chair would tilt even with a slight push, even in the straight-back mode. I attached this chain to the armrests and secured it behind the backrest and it provided even better support than the chair when the straight-back mode worked. This suggests that the joints have good strength as they are under constant stress. They are also nice and uniform with no broken welds. While I suspect that's not what the chain is intended for, it looks like they can handle several hundred pounds of load, even with most of the load concentrated on small sections of chain. would recommend.
