When you sit, you should be able to feel the prssure of bones in each cheek that press through your glutes toward the seat...

These are your "sit" bones.

You can probably feel them if your press your butt cheeks with your hands too.

Good advice from Deanna with how to find them too...

These are the bones that should be supported by your seat, and since not all women have the same shape/size pelvis there are a variety of shapes in women-specific seats.

Your goal is to find one that supports your sit bones. It doesn't matter how wide or narrow the flesh of your bottom is, it is your sit bones you need to heed.

If you have been finding the seat you use comfortable, you don't get back or leg pain, and your but and "girly bits" are ok... just stay with the seat you have, Nokomis... if its working, don't try to fix it.
