Branch, Shore Mesh
A feature-rich midrange chair with forward tilt, adjustable depth, tunable lumbar and 5D arms.
Winner whenMaximum useful adjustability around the $500 mark
Independent testers found the 5D arms easy to knock out of position and somewhat rattly.

HON, HONI2MM2AMC10BT, Black
A practical mesh-back task chair with an adjustable lumbar pad, seat slide and contoured foam seat.
Best forReliable mid-price lumbar and seat-depth adjustment
The plastic lumbar pad can feel firm and the all-black Amazon configuration has limited finish choices.

An all-mesh chair whose flexible back, linked arms and self-adaptive lumbar follow movement without many manual settings.
Best forBreathable dynamic support for average-height users
The lumbar height is not independently adjustable, which makes body height especially important.
