Armrests vs. No Armrests (spoiler: the latter)

Latissimus Dorsi muscle: "a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back", which "can bear the weight of your arms and also relieve the upper trapezius" 🙂

Trying this out to reduce tension headaches and also increase mobility.

Dialing in lumbar support & seat pan depth.

Counter-intuitively (to me), I decreased (retracted) the extension of the seat pan so I can sit on my "sit bones" of my pelvis properly and have the lumbar support brace my lower back. Feeling better.

Sitting in a Steelcase Gesture.

Its seat pan is shorter than what I'd prefer--I can fit an entire hand-width between the end of the seat and the back of my knee. So initially I had extended the seat pan fully out.

This meant my "sit bones" of my pelvis were a bit behind/above the back of the seat pan (I think)--so I was not sitting on them. My lower back was not fully supported by the lumbar support.

Weird to describe, but due to the seat pan depth, retracting it let me rest my pelvis "sit bones" on the rear of the seat pan comfortably, and also it has the benefit of backing my lower back snugly into the lumbar support.

Immediately feeling better 🙂 🥳 ✅
