I had a junk chair and I kept having backache so I bought this thing that's called the Joobie, and now I no longer have back aches.
I looked at used Herman Miller Aerons and all that, but they were still expensive as shit and only very basic. The used ones had options for add-ons like armrests (which I absolutely need) and a bunch of other shit it was still over double the price of the Joobie. Not paying that much for a used chair.
Also got it in black because I don't wanna see stains on the chair, but this photo was nice.
