Black Friday Top Pick: C300 PRO V2
From head and neck to back, waist, and arms, four support zones move together with your body.
SyncroFlex helps the backrest adjust as you sit, creating a closer fit for different body types. It feels more natural from the very first lean.
Not just for the lumbar. It helps support extend down toward the sacrum, filling the space where comfort is often lost.
A larger armrest surface supports more of your forearm, helping reduce pressure on the shoulders and elbows.
