Topstar Sitness 50 taburete de asiento activo, verde manzana, altura regulable, base anular engomada (SI69 G05)

Unlike conventional office chairs that lock you into a static posture, the Topstar Sitness 50 turns sitting into a dynamic, core-engaging activity. Its 3D movement mechanism lets the seat tilt in all directions, encouraging constant micro-movements that strengthen your back and improve circulation. The apple green 100% polyolefin fabric is not only vibrant but also extremely durable and easy to clean, making this stool a fresh addition to any workspace, classroom, or home office.

Highlights

• Active sitting concept with 3D movement for improved posture and core strength
• Height-adjustable gas spring from 42 to 55 cm for versatile use at standing desks or counters
• Rubberized ring base with integrated floor protection and non-slip grip
• Durable apple green polyolefin fabric, 100% recyclable and easy to maintain
• GS-tested for safety and quality, made in Germany

In daily use

The Sitness 50 excels as a perch for quick tasks, brainstorming sessions, or as a secondary seat in collaborative spaces. The ring base allows your feet to rest comfortably while the stool's gentle rocking motion keeps your legs and back active. Because the seat height adjusts smoothly, you can transition from a standard desk to a standing-height table without changing stools. The rubberized base prevents slipping on hard floors and protects sensitive surfaces from scratches.
