This sitting stool offers a dynamic sitting experience thanks to the movable ring element and is perfect for home offices. With adjustable height and stylish design, it's a smart choice for your workspace.
When do you choose this product?
When do you need a dynamic stool?
A stool such as the Sitness Bob is ideal when you want to alternate between sitting and standing during your working day. This product offers an active seating experience thanks to the moving ring element, perfect for home offices or flexible workspaces where traditional office chairs are too large.
Why choose this compact size?
With a seat size of 365 x 365 mm, this stool fits into smaller spaces where a full office chair is not practical. The height-adjustable seat (440-570 mm) allows you to adapt the stool to different desks or tables, so you can work ergonomically regardless of your height.
How does dynamic sitting work?
The moving TPU ring element beneath the seat creates a horizontal swinging effect that keeps your body in balance. This movement encourages dynamic sitting and prevents you from sitting statically. The chrome-plated gas spring ensures smooth height adjustment.
Practical considerations for daily use
The load capacity of 110 kg makes this stool suitable for most users. The aluminium design footrest provides stability during movement, while the 100% polyester upholstery is easy to keep clean. The manufacturer recommends a maximum sitting time of 4 hours per day — start with short sitting periods and gradually build up.
