8° Sitting Wedge Cushion with Coccyx Cut-Out
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 supportive seating surface.
The cushion includes a coccyx cut-out section which reduces direct contact with the centre rear of the seat. This design allows weight to be distributed across the surrounding cushion surface.
The wedge is especially popular for use on car seats as the gentle angle can create a comfortable driving position. It can also be used on office chairs, sofas or other seating surfaces.

Clinical Research & Evidence
Peer-reviewed studies supporting Coccyx Seat Wedge 8 Degree | Posture Support 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.
