The Anthros chair doesn't include a head or neck support because its design prioritizes optimal posture and spinal alignment. The chair's support system encourages a natural, upright position that helps maintain the spine's natural curve without relying on headrests. When seated correctly with the Anthros chair's pelvis support holding the pelvis in neutral, the upper body remains balanced, allowing the head and neck to align naturally. Adding a headrest could actually disrupt this posture by encouraging users to lean back or slump, potentially leading to neck strain and discomfort over time. Anthros believes that by focusing on core postural support, users experience reduced pain and improved comfort without needing additional neck or head support.
