Bolsters, roller cushions or cushion rolls are used for various yoga asanas, where they optionally strengthen or soften the stretching effect of the various asanas. They allow for an elevated sitting position, causing the pelvis and upper body to straighten.

It becomes possible to assume positions for which the flexibility or strength would otherwise be lacking.
They are also very good for passive backbends to relax the heart - lung area and open the chest (heart space "opening", chest expansion). 
Forward bends over the roller cushion can calm the mind and nervous system. 
Reverse postures such as Viparita Karani produce a strong restorative effect.
Positions especially in Yin Yoga and Restorative Yoga can be held longer and more relaxed.
Also in physiotherapy and as a seat cushion for meditation our bolsters are very suitable.

Buckwheat hulls are an extremely breathable and heat-retaining natural product.
These buckwheat hulls are particularly suitable as a filling material for sleeping pillows, meditation pillows, seat cushions, etc. Buckwheat offers several advantages as a filling material, it gently adapts to your body and at the same time gives you a stable, firm seat.
Due to the flowing behavior of buckwheat in the bolster, it acts as an optimal support in any position.
The breathable filling material ensures a good exchange of moisture during prolonged sitting and has a temperature-balancing effect.
Compared to spelt, buckwheat offers the advantage that it hardly rustles.
