8° Sitting Wedge Cushion
This angled seat wedge cushion is designed to create a slightly forward sitting position when placed on a chair. The 8° incline encourages a balanced sitting posture while providing a comfortable seating surface.
The wedge is especially popular for use on car seats as the gentle angle can create a more comfortable driving position. It can also be used on office chairs, sofas or other seating surfaces.
The lightweight design makes the cushion easy to move between different seats at home, in the office or while travelling.

Clinical Research & Evidence
Peer-reviewed studies supporting Seat Wedge Cushion 8 Degree | Ergonomic Posture Chair Cushion
Patients with tailbone pain were approximately 5 times more likely to prefer wedge cushions over donut cushions in clinical research
Conservative management including appropriate cushions is successful in approximately 90% of coccydynia (tailbone pain) cases
For most people with coccydynia, the best cushions to use are wedge cushions. The goal is for the painful tailbone to 'hover' over the cut-out, reducing weight-bearing on the coccyx.
