Varier Variable Plus – Ergonomic Masterpiece with Extra Support

The Varier Variable Plus takes active sitting to the next level. Based on Peter Opsvik's original 1979 design, this version adds a sleek backrest to the classic. This way, you can enjoy the proven benefits of a kneeling chair, with extra support when you need it.

Active Ergonomics, Smart Comfort

Just like the original Variable, the Variable Plus also encourages a dynamic sitting posture . Your body remains in gentle motion, your spine stays straight, and your muscles stay engaged. The added backrest provides support during rest periods or longer work sessions, without disrupting your natural posture.

Why choose the Variable Plus?

  • Improves posture and back support

  • Activates core muscles while sitting

  • Prevents tension in the neck, back and shoulders

  • Backrest with soft padding for extra comfort

Timeless Scandinavian Design

The Variable Plus is designed to balance functionality and aesthetics . Its flowing silhouette and natural materials fit perfectly into any modern interior.

  • Solid beech wood runners

  • Upholstery in quality fabrics or wool (Revive, Re-wool, Fame, etc.)

  • Choice of multiple color combinations and wood finishes

  • 360° handmade in Europe with attention to detail and sustainability

Movement Brings Energy

Thanks to its signature curved runners, the chair moves with your body. This keeps your circulation active and your concentration high – ideal for work, study, creative work, or meditative moments . Lean back against the rounded backrest and seamlessly switch between active and relaxing sitting.

Custom Ergonomics

The Variable Plus is suitable for:

  • Home workers who want to combine comfort and health

  • People with back problems or poor sitting posture

  • Students, writers and creatives

  • Anyone who wants to upgrade their workplace with a unique and healthy seating furniture

Note: The knee support is intended for support, not to bear full weight. It takes several days to weeks to fully master the active sitting principle – but the result is a noticeably healthier sitting posture.

Accessories for Extra Comfort

For hard floors, we recommend the optional Soft Tape accessory: a felt strip that attaches under the wooden runners. This protects your floor and improves grip.

Varier Variable Plus – Moving Seating with Luxury Support

The Variable Plus combines the unique benefits of an ergonomic kneeling chair with the added comfort of a backrest. Whether you're working intensively or simply want to sit comfortably with a straight back, this is the perfect balance of design, movement, and comfort .
