A yoga bolster is a firm, supportive cushion used mainly in restorative and gentle yoga. It props the body so you can fully relax in a pose — supporting the back in a reclined position, under the knees, or beneath the chest in resting poses. It lets muscles release completely without effort or strain.

In restorative yoga the aim is total relaxation, so the props do the holding. A bolster under the spine opens the chest while you rest; under the knees it eases the lower back; across the thighs it supports a forward fold you simply melt over.

By taking the effort out of a pose, a bolster lets the nervous system settle deeply, which is why it is central to restorative and pregnancy practice. Firm cushions or tightly folded blankets make a good substitute.

Frequently asked questions

Can I use a pillow instead of a bolster?
Firm cushions or tightly rolled blankets work, though a true bolster is firmer and holds its shape better for full support.
Is a bolster only for restorative yoga?
It is most used there and in prenatal yoga, but it is also handy for comfortable seated meditation and gentle supported stretches.
