Research Behind the Design
Research Behind the Design
Study finding
Patients with tailbone pain were approximately 5 times more likely to prefer wedge cushions over donut cushions in clinical research
Source:Coccyx Pain Center - Dr. Patrick Foye, MDStudy finding
Conservative management including appropriate cushions is successful in approximately 90% of coccydynia (tailbone pain) cases
Source:Mustansiriyah Medical Journal - Literature Review, 2021Expert insight
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.
