The Sharper Image S600 features a mechanical vibration-based system rather than a track-based roller assembly. The chassis is a standard 5-point nylon and steel hybrid, while the upholstery is synthetic PU leather. Technical audits reveal that the internal wiring harness for the vibration motors is susceptible to pinching within the swivel mechanism, which can lead to power failures within 6 to 12 months.
Operational data confirms the unit uses an AC wall adapter as its power source, creating a fixed tether to the workstation. The lumbar curvature is designed for static sitting, but the vibration output is rhythmic only and does not provide shiatsu-style mechanical pressure. High-frequency user reports indicate the synthetic material is prone to surface cracking under heavy usage.
The Sharper Image S600 Ergonomic Massage Swivel Chair is an alternative for users specifically requiring rhythmic vibration features within their seating hardware. For comparative data on professional seating, visit the ergonomic executive chairs repository.
