Aeris: Active Sitting with Swopper, Numo, Linu, Muvman, and Muvmat
Aeris products differ significantly in terms of movement principle and application area. The deciding factor is whether dynamic sitting, flexible communication, varying working heights, or active standing needs to be supported.
In a Nutshell
Swopper, Numo, Linu, Muvman, and Muvmat fulfill different tasks. Therefore, a good comparison doesn't start with design, but with activity, sitting duration, body measurements, movement needs, and room concept.
What Active Sitting Really Means
Active sitting doesn't describe a single piece of furniture, but a working principle: the body should be able to change its position more frequently. Small movements don't replace breaks or walking, but they can reduce rigid, prolonged sitting. It's crucial that the entire workstation is suitable – including desk height, monitor position, lighting, and work organization.
Swopper: Dynamic Sitting with High Freedom of Movement
The Swopper is designed for movement forward, backward, and to the side. It is suitable for users who consciously want to sit actively and are open to a different seating experience. Seat height and spring hardness must match body weight and leg length. A gradual adjustment period is advisable, as the musculature is more engaged than with a classic swivel chair.
Numo and Linu: Flexible Seating Solutions for Communication
Numo and Linu excel in meeting rooms, reception areas, project rooms, and flexible zones. Here, not only ergonomics matter, but also mobility, ease of cleaning, room aesthetics, and the typical duration people sit. Different requirements apply to all-day screen work than to meetings or short stays.
Muvman: Between Sitting and Standing
The Muvman supports work at elevated and changing positions. It can be used with height-adjustable desks, at reception areas, in laboratories, workshops, or creative workspaces. It's important that the standing height, tilt, and range of motion match the task.
Muvmat: Movement at the Standing Workstation
The Muvmat is not a classic anti-fatigue mat, but an active mat with different textures. It encourages small shifts in weight. It should lie securely, not become a tripping hazard, and only be used where there is enough space for movement.
| Product | Typical Use | What to Consider? |
|---|---|---|
| Swopper | Active sitting at the workstation | Spring hardness, seat height, adjustment period |
| Numo/Linu | Meetings, reception, flexible rooms | Sitting duration, table height, room concept |
| Muvman | Standing stool and changing heights | Working height, stability, range of motion |
| Muvmat | Active standing | Secure stance and suitable environment |
Typical Selection Errors
- A product is chosen based solely on its appearance.
- The actual sitting or standing duration is not considered.
- The adjustment period is underestimated.
- One model is expected to suit all employees equally.
- The rest of the workstation remains unchanged.
FAQ
Is active sitting suitable for the whole day?
A combination of sitting, standing, walking, and movement breaks is sensible. No single piece of furniture should force the same position permanently.
How long does the adjustment period take?
This is individual. Shorter periods of use at the beginning help to realistically assess the feeling of movement.
What is the difference between Swopper and Muvman?
The Swopper is a dynamic chair for active sitting. The Muvman supports elevated sitting and standing positions.
Is Numo suitable for meeting rooms?
Yes, especially for flexible communication areas and moderate sitting times.
Is trial sitting necessary?
Highly recommended, as the feeling of movement, suspension, and seat height are perceived individually.
