Briefly explained
What is the Interstuhl UP Stool?
The UP is a mobile seating option for active, temporary sitting phases. Its convex base allows movement in different directions. This enables the body to change its position regularly.
The height is continuously adjusted via a loop. A carrying groove under the seat makes it easy to move between the workplace, meeting room, and home.

Colors and Design
From neutral to bold: the colors of the UP family
Interstuhl offers six colors for the classic UP. The ECO UP has its own, more muted color palette. Screen displays may differ from the actual color tone.
UP, UP Junior, and STAND UP
For calm work environments or targeted color accents.
Black Grey White Lemon Yellow Salmon Orange Pastel Turquoise Red
ECO UP
Natural tones with visible material particles.
Cream White Pastel Orange Pastel Blue Wine Red Steel Blue Black Gray
Which color suits which room?
Black, Grey White, and Black Gray integrate calmly into existing furnishings. Yellow, Red, or Pastel Turquoise are suitable as orientation points in learning zones and creative areas. The muted ECO UP tones go well with wooden surfaces and homely office concepts.
Construction
How the UP enables movement
The rounded, non-slip base is slightly curved. This allows the stool to react in different directions while the foot maintains ground contact.
The UP is intended as an addition for changing sitting positions. For long, continuous screen work, a properly adjusted office swivel chair with a backrest remains the more sensible primary seating solution.
Movable Base
The convex shape allows for small shifts in weight.
Stepless Height
The seat height can be adjusted within the model range.
Carrying Handle
A carrying groove and loop facilitate quick changes of location.
Slip Resistance
The base is designed for stable contact with the floor.
Applications
Where can an UP stool be used?
Its compact shape makes the UP particularly useful where people frequently change positions or rooms.
At the Desk
As a temporary alternative to an office chair, the UP supports conscious position changes during the workday.
In the Home Office
The compact stool can be quickly stowed away and moved between the work table and living area.
In Meetings
For short consultations, an additional seating option is quickly created without moving a heavy chair.
In Workshops
The stool suits changing groups, flexible room layouts, and active work formats.
In School and Learning Spaces
UP Junior offers children a dynamic seating option for learning phases and creative tasks.
At Standing Workstations
STAND UP serves as a support at high tables for switching between standing and leaning sitting.
In Reception and Waiting Areas
For short-term needs, the UP can be available as easily movable additional seating.
In Canteens and Break Rooms
The ECO UP is also recommended by Interstuhl for dining tables, canteens, and communal areas.
For Parents and Children
Standard UP and UP Junior can be combined as a shared dynamic seating solution at a family workstation.
Material and Manufacturing
What are UP and ECO UP made of?
