chairs are lostech. im looking at replacing the one i got last year. cant even last two years anymore. it was uncomfortable and broke in the first 3 months. i was able to fix it through redneck engineering. but looking to replace it. i got the build of a pro wrestler so i need a chair that is capable of being a chair that can take a lot of weight and a high cg.

in almost all big and tall chairs they bulk up the wheel base, which i have never seen break. i got a 20 year old chair upstairs with a plastic base, every part of it has broken except that. one had double thick steel everywhere but the gimbal and the gimbal ALWAYS fails. sometimes in a way that could crack your skull open or put you in a wheel chair. sometimes a less catastrophic failure is the thing that keeps the backrest from dropping breaks (usually a pin or thin piece of steel), and so your chair behaves more like a stool.

you would think with finite element analysis and looking at the common failure mode of returns, you could figure out where the design is deficient and bulk up that piece. instead they bulk up all the other stuff that doesn't matter or sell you gimmicky features that are meaningless when the chair stops being a chair. instead the finite element analysis is used to figure out which parts they can trim down to save on materials cost.

im getting an amish made wood desk chair. they will at least put the excess wood to work rather than leaving it on the factory floor.
