Too firm and large for under the knees.

I would not recommend the cylindrical bolster for under the knees as indicated in the comparison sheet. It's way too large and firm to be comfortable under the knees, or likely if you're a petite person. I unfortunately used this comparison sheet to guide my purchase, but since I bought it during the recent sale, I am unable to exchange it. It is heavy, with thick material and seems well constructed if that's what you're looking for.

LOVE this bolster!

Wonderful prop! Use it daily in my meditation and yin yoga practice. Retains its shape very well and is super versatile. Highly recommend!

Beautiful fabric and well constructed.

Beautiful fabric and well constructed. Best of all it is a local product and delivery was easy and fast.

Cylindrical Bolster

This is a great bolster for really being able to lay back and open up the pectoral muscles that so often hold tight in poor forward posture. It is the perfect shape to support your spine, but allow the shoulder blades and shoulders to drop back as you breathe!
