Though this chair is not specifically designed for pelvic disorders, I find it absolutely helpful!

For those like me who have pain on the coccyx and cannot seat normally, this chair has a movable seat, it slides forward and the coccyx area is free, your back is straight and you could even use it in what I call the "saloon style", with the back on your breast, leaning against it, in fact, takes away the weight from the coccyx.

Hi
Thx for posting this chair.
Looks cool... must your anal area touch when sitting as you decribed or can it hang over the side?
Thx!

Hi,

No, the anal/coccyx area doesn't touch the chair if the seat is moved forward enough. I imagine it also depends on the person's build but should work.
