RH Logic 400 Ergonomic Chair

RH Logic 400 Ergonomic Chair

The RH Logic 400 has great ergonomic features and durability. It offers a high backrest and active sitting through pivot points at the knee and hip. The seat includes a layer of wool, which helps improve ventilation. Seat- and back-angle can be adjusted independently. The chair is simple to adjust and the controls are easy to access.


To benefit fully from a specialist chair, you may need training to understand the best postures and habits. We recommend that you purchase training and setup when buying this product. This one-off charge (however many units you buy) includes assembly, configuration, full user training and removal of all waste packaging.

  • The Logic 400 ergonomic chair is fitted with an inflatable lumbar support.
  • Optional armrests (pivot top) and neck rest available.
  • These ergonomic chairs are made to order and delivery may take up to 2 weeks (we do not charge your credit card until we are ready to despatch).
