3 options

SIHOO, Black, Standard
SIHOO’s newer full-body adaptive chair adds seat depth, 8D synchronized arms and a broader sacral-lumbar system.
Winner whenA tall, highly adjustable all-mesh chair with a supportive headrest
The large number of moving parts takes time to tune, and the 8D arms may feel overactive.

Ergohuman, ME7ERG-GEN2, Black
A highly articulated all-mesh chair with a headrest, adjustable back height, seat slide and multi-axis arms.
Best forPeople who want a headrest and many independent support controls
The segmented frame and prominent lumbar area can feel busy or overly assertive for sensitive backs.

Steelcase, Graphite Gray Fabric
A premium padded chair built around highly mobile 360-degree arms and a broad fit range for device-heavy work.
Best forShared desks, taller users and the widest armrest range
The lumbar support is less independently tunable than Leap, and the arm pads can shift when used to push up from the chair.
