RH Logic 300 Ergonomic Office Chair Product Details

The RH 300 chair has a generous range of standard features and multiple optional extras for individual comfort, which results in a comfortable office chair to help you work better and comfortably throughout the day. With an RH Logic 300 chair you can gain maximum movement from a seated position with the free float mechanism, which is arguably the best chair mechanism on the market. 

The RH 300 chair is an evolution of the successful RH Logic 3, with the design inspired by 2 joints; the knee and the hip. When leaning backward or forward, your feet always remain in contact with the floor, minimising pressure against the underside of your thighs. Secondly, the back rest height remains constant, regardless of the seat angle. The result is a chair which improves circulation and generates greater muscle stimulation to provide the user with greater wellbeing and increased productivity.

To get the maximum benefit from the RH 300 chair you can also choose for one of our trained engineers to setup the chair with you and talk you through the multiple features. You will also receive a sitting tips booklet to ensure you always know how to use and adjust your new RH Logic chair.

Please note: We supply the RH Logic 300 with an inflatable lumbar support as standard.
