Before you choose

Automatic response or settings you choose?

Cosm's Auto-Harmonic Tilt responds automatically; Gesture provides tension and back-stop controls. Try reclining from the same working posture, then ask which Gesture setting you changed. The choice is about the adjustment approach you want to evaluate, not a universal comfort ranking.[1][3]

Does the seat and arm configuration match your desk?

Check the selected Cosm cylinder and arm type against the order, and compare its seat edge with Gesture after setting seat depth. Cosm fixed, Leaf and height-adjustable arms are different choices; one photographed arm cannot demonstrate the others.[1][3]

Is a high back being mistaken for a headrest option?

Specify Cosm High Back rather than Low or Mid Back. Separately confirm whether Gesture includes its optional headrest. Compare the actual upper-back/head contact during a trial rather than treating these different configurations as equivalent accessories.[1][3]

Store or seller checklist

Request Cosm's back height, cylinder and arm order codes, then Gesture's recline-control demonstration and explicit headrest choice.
