Frequently asked questions
What is the difference between the RH Logic 400 and the RH Logic 300?
The primary difference is the backrest height. The RH Logic 400 features a high backrest (620mm) designed to provide support across the full length of the spine, including the shoulders. This makes it the preferred choice for taller users or those who require more comprehensive upper-back support. The Logic 300 uses a medium-back design but shares the same ergonomic movement technology.
How does the RH 2PP (Two-Point-Principle) support active sitting?
The 2PP mechanism ensures that the chair's pivot points are perfectly synchronized with your body's natural joints at the hips and knees. This allows you to move freely and recline while the backrest maintains constant, upright support. By encouraging micro-movements, the chair helps maintain blood circulation and reduces fatigue during long shifts.
Can the RH Logic 400 be used for 24-hour shift work?
Yes. The RH Logic 400 is specifically engineered and certified for 24/7 use. It is built with high-specification components, including a reinforced aluminium base and a heavy-duty gas lift rated for 150kg (23.5 stone). For intensive environments, it also features exchangeable seat and backrest pads to extend the life of the chair.
How do I adjust the inflatable lumbar support?
The inflatable lumbar pump is an integrated air cell in the backrest. You can manually adjust the firmness by using the hand pump located under the seat or on the side of the backrest. This allows you to fine-tune the support to the exact curve of your lower back, providing relief for musculoskeletal issues and back pain.
Is the black base more durable than the polished version?
The structural durability is identical; both are made from heavy-duty cast aluminium. The choice is purely down to maintenance and style preferences, with the black base being more forgiving in terms of visible wear and tear.
