The RH Logic 220 is a redesign of the original Logic. It's been reworked to fit fast-paced, modern, agile environments. Compared to the original, the Logic 220 offers greater seat depth, softer cushioning and an improved lockable movement mechanism for freedom of movement. The seat features a rounded waterfall edge to reduce pressure on the thighs, while the backrest - which on the 220 is extra tall, now features a soft curve to keep the back upright, mobilising the arms and shoulders for increased comfort in any position. RH Logic 220's high back has an inbuilt inflatable lumbar cushion as standard so all users can quickly find the most suitable level of lower back support. Environmental efficiency remains at the core of the RH Logic 220's design. It's long-lasting, free from toxic substances, has easy-to-replace parts and is entirely recyclable.
