>>12951469it's probably easier to explain those tiers of chairs in general terms.
so, i used to have some shoulder pain and stillness after sitting at my desk for a long time, i.e a whole work day. The reason was when my arms where resting on the arm rests they were in the wrong position my shoulder would be slightly raised when it was in that relaxed position.
on gamer chairs and cheaper chairs, the chair arms would go up and down, but they were in a fixed width away from my body. A fancier chair will let you adjustment the arms not only go up but move inwards and outwards or angle them slightly. you'd be surprised how much difference having the arm be slightly closer or further away from you can have to make your arm sit in a more natural position when you're holding a mouse or hands on keyboards. your shoulders shouldn't be "stretched" up or down when you're in a natural sitting position. these little movements like angles of the arm rests can help when you shift your position too.
this kind of logic applies for legs too. most chairs will have just a regular gas lift that will let you set the rough height of a chair at a particular position, so that your feet sit flat on the ground when you're in that relaxed position. this is pretty good for the most part but fancier chairs will have some seat movement back and forth to make that feel a little better, even fancier chairs like the herman millar variants will let you adjust the front lip of the seat independently, so that it's not uncomfortable or excerting pressure on the back of your leg/thigh when you're sitting in that "relaxed" position.
beyond that kind of stuff, often mesh is favoured on ergo office chairs more than fabric. mesh gives you some breathability but you lose the padding for that, so you need to make up with that "loss of comfort" by making things more adjustable to be comfier. that would be a difference between the steelcase and the herman miller chairs for example.
legitimately the weight of the chair also matters, as it helps with the adjustments in posture as your body moves about and less movement in the chair helps with those bits of fatigue that build up over a day.
so, the price tiers often come down to adjustability, or materials. some will be plastic with little flex or others will be higher quality with movement and flexibility in places like the back rest that help with longer sitting sessions.
the embody for instance has a super fancy back rest, that's suppose to help your back sit in a more natural position. or the ability to set the back support into a place that helps prevent you leaning over hunched forward or unevenly leaning to compensate for an uneven seat or arm rests. the cheaper chairs will just have a fixed back with very little flex or padding over hard frame. the padding compensates for things but making it soft, but doesn't actually help in making your back sit more naturally in a better position.
>>12952324there are compromises, the steelcase amia chair for instance is a padded fabric chair with a lot of adjustments, where as something like the aeron is just mesh, which if you're sitting around in your underpants is obviously not as comfortable to sit on, but its fine if you're in pants all day where the breathing of the mesh can help a lot.
stay away from the vinyl / bonded leather stuff, the cheaper fabrics like that often just start flaking and peeling pretty quickly ( speedup by sweat and stuff) and it's really fucking annoying to have that shit all over you. a lot of cheaper gaming chairs and office chairs use that kind of material and it's just hot trash but it looks like leather or shiny and cool when you get it.
just get something that has a normal fabic and not that shit if you want padding and comfort.
>>12951896king. my old office had them, i should really just get another one rather than the mirra.
