11° Sitting Wedge Cushion
This angled seat wedge cushion is designed to create a slightly forward sitting position when placed on a chair. The 11° incline encourages an upright sitting posture while providing a supportive seating surface.

The lightweight wedge can be used on a variety of seating surfaces including office chairs, car seats, sofas and wheelchairs.

Clinical Research & Evidence
Peer-reviewed studies supporting Seat Wedge Cushion 11 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.
