Measuring sit bones--is my yoga mat defective?

[Ana]

Here ya go.

Thanks for the thread link but I've already done a search for "sit bone measurement", etc and browsed all the threads

I think I might be doing something wrong?

Try a thicker mat, or folding the one you have in fourths. It's got to be able to compress enough to leave dents in the paper.

Set it on a hard surface - a flat stepstool, a hard chair, or an uncarpeted stair.

Before you take the impression, sit on the stool or whatever surface you plan to use without the mat, and wiggle your spine and pelvis around until you can feel your sitbones pressing against the surface. Then use that body knowledge to stick your sitbones out when you do take the impression.

HTH.

Oakleaf--I tried sitting my homemade butt-o-meter on the yoga mat (which was on a hard surface) and on the hard surface alone. I will try folding my yoga mat, though

Unfortunately, I do not have a stepstool The chair I use at home is a ball chair

Trying to ride on this Jett saddle is killing my sit bones
