Nottingham sit-stand chairs

Some aspects of the Nottingham seat:
- Postures range from standard upright sitting to sitting up to 70% of the user’s standing height.
- Relieves loads on the spine by reinstating the natural lumbar curve.
This chair can take sitters near the 135° thigh-torso angle first described by Keegan (1960).
This design bypasses limitations associated with reclined sitting such as greater neck/shoulder loads from increased neck tilt and increased arm loads and reach as users move back from their work as well as increased eye/neck strain from lowering users relative to their visual target (e.g., computer screen)
It avoids unstable sitting postures associated with forward sloping seat pans.
- It can accommodate almost everyone at a single fixed height desk or counter.
- It supports working at stations that lack knee clearance (e.g., clean rooms, laboratories)
- Can accommodate very small / short users (e.g., 12 inch popliteal heights) with standard pneumatic seat cylinder.
- Enables employees who deal with the public (e.g., reception counters) to sit while the public stands – without the corresponding increase in risk of neck/shoulder injury from sitting while the client stands.
- It improves reach (especially useful for grocery checkout clerks, clean rooms, reception counters, postal centers etc.)
- It is easier to rise and sit on the chair (useful for users such as pregnant women and the elderly)
- The biomechanical advantage of sitting with an open angle about 120° greatly facilitates reach and ease of getting up and down.
- It helps special populations such as pregnant women (easier to rise and sit; easier to breath, reduced loads on the spine); people with poor circulation or foot swelling (improved circulation); people with back and knee injuries; short users (brings them up to the desk height); musicians (improved breathing) and others.
