Each RIEIOR chair series features distinct adjustment capabilities and dimensional specifications. When selecting a model, carefully consider your body weight, height, and intended usage requirements. For precise fit, we recommend a direct dimensional comparison between your incumbent seating and the published specifications to validate fit before purchase.

All RIEIOR office chairs are designed based on ergonomic concepts. To a certain extent, they can help people maintain a healthier posture and relieve the discomfort of sitting for a long time. However, they are not medical chairs that can completely treat certain pain diseases in the human body. Therefore, there is no guarantee that they can cure your physical pain. Please consult a medical or physical therapy professional for professional help.
