Most seat cushions add padding. This one takes it away. A U shaped gap at the back lets the tailbone hang over empty space instead of resting on the chair, and every other feature of a coccyx cushion follows from that single piece of geometry.
The Cutout Is The Product
On a flat seat, body weight travels down through the pelvis and the coccyx takes a share of it. Remove the material directly beneath the tailbone and that share goes to the sit bones either side instead, which are built to carry it. Nothing else about the cushion changes that; the shape does all of it.
Built For A Desk Chair
Contoured for a standard office chair rather than for a car seat or a sofa. That matters because a cushion designed for a deep soft seat sits differently on a hard flat one, and a coccyx cutout only works if it lines up with where you actually sit.
Cushion Specifications
| Detail | Figure |
|---|---|
| Shape | Contoured U with a rear cutout |
| Effect | Suspends the coccyx clear of the seat |
| Designed for | Desk and office chairs |
| Stability | Holds position on a chair rather than sliding |
| Suitable through | All three trimesters |
Which Way Round It Goes
The cutout faces the back of the chair. Turned the wrong way it does nothing at all, which is the most common reason people report a coccyx cushion made no difference to them. Sit fully back so the gap sits under the tailbone rather than behind it.
It Works Through All Three Trimesters
Seated posture changes as pregnancy progresses and the weight distribution moves forward. A cutout cushion keeps working through that because it removes pressure from one fixed point rather than supporting a particular posture.
A Cushion Is Not A Diagnosis
Offloading the tailbone helps with pressure from sitting. It does not treat whatever is causing pain, and pelvic or back pain in pregnancy has several possible causes that a cushion does not distinguish between. If it hurts, the person to ask is your midwife, doctor or physical therapist, and a cushion is at most part of what they suggest.
Cushion Questions
Which way does the cutout face? Toward the back of the chair, so the gap sits directly under the tailbone.
Will it work in a car? It is shaped for a desk chair. A car seat is a different geometry and the cutout may not line up.
Does it slide on the seat? It is designed to stay in position on a chair rather than shifting as you move.
