Home / Our Products / Seat Models / Classic / Classic Core+

Description

The Classic Core+ combines the wide, soft seat from our popular Classic model with the contoured Core+ backrest , which provides optimal support for the lower back and lumbar region throughout the workday. The slightly lower seat height makes the chair particularly suitable for working close to the work surface, while the larger 65 mm casters allow for smooth and easy movement even while seated.

With the easy-to-reach controls under the seat, you can quickly adjust both the seat height and seat angle to create variety, enhance comfort, and ensure optimal ergonomics. The chair is equipped with a sturdy four-lever mechanism with leaf springs, and the seat angle can be adjusted up to 15° to provide an active and supportive sitting position.

Ergonomic benefits:

  • Wide, soft seat for maximum comfort during long workdays.
  • Larger wheels (65 mm) allow for smooth maneuvering close to the work area.
  • Under-seat controls for easy adjustment of height and seat angle.
  • Also available in Classic Advanced to suit both women and men.

Perfect for:
  • You work at a lower height and need to be able to move smoothly between tasks.
  • Looking for a softer seat combined with stable and supportive lumbar support.
  • Wants to be able to fine-tune their sitting position throughout the day for improved ergonomics and comfort.
