Clinical Research & Evidence
Peer-reviewed studies supporting Seat Height Raiser Cushion 8cm | Foam Chair Booster 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.
