The Buttafly is a versatile fitness product to help transform your posture

An ergonomic seat

Designed by Physiotherapist and Yoga Teacher TillyLou James, the Buttafly was originally conceived in her quest to find a more comfortable alternative to the regular rectangular Yoga block for sitting cross-legged on the floor. Since its launch 3 years ago, it is now the Yoga block of choice for meditation and Yoga teachers passionate about the benefits of good posture for overall health and well-being as well as for helping to avoid back pain.

The Buttafly can be used independently on the floor and also supplementary to a chair and supports the pelvis in way that makes it easy to sit with good posture. Unlike when using a cushion, lumbar roll or other back support, the Buttafly does not do the work for you but by laying the correct foundation helps to activate the core muscles, building strength and at the same time as stimulating the body’s innate balance systems. The Buttafly may be used in this way for rehabilitation purposes under the guidance of a Physiotherapist, Occupational Therapist, Teacher of the Alexander Technique or other professional and by anyone wishing to perform chair-based exercises and Chair Yoga.

A versatile Yoga block 

As well as a seat the Buttafly works well in place of a conventional Yoga block for many asanas – the fluid curves and wedged shape often mean that it provides better support and is more comfortable too.

The Range

The Buttafly comes in 3 models


The Standard Buttafly is the same height as a regular rectangular Yoga block – 5 cms high at the front edge. For sitting cross-legged on the floor, it is generally more suitable for those with greater flexibility of their hips. It is the most versatile model for use as a prop for Yoga and Pilates, and also the most commonly used model for back care.



The Tall Buttafly is 10 cms at the front edge, the same height as two regular Yoga blocks stacked together and also similar in height to a bolster. Generally speaking, it is more comfortable for those who are not so flexible in the hips – meaning that in the cross-legged position their knees are higher than the hips when ideally they should be at the same height as the hips or slightly lower.



The Flat Buttafly does not have a sloping upper surface and is designed for use in sitting as a “stacker” – to be used with under the Standard or the Tall Buttafly to provide additional height. It is 5 cms high and can also be used as a versatile prop.

“I have just received my Buttafly – it is simply wonderful! I started practicing Yoga when I was 26, I am 71 now and have a hip replacement.

The lotus position was never easy for me. On the Buttafly, I am sitting better than I ever remember doing and I can’t thank you enough!”

Valerie Bracken

“Initially I was a little skeptical about the potential benefits of the Buttafly and so it was to my great surprise that I was able to experience a sense of space at the base of the spine… It provided an openness and lightness in the sitting position. I have already put in my order and shall not hesitate to recommend this product to others.”

“I love to sit for meditation, and am generally a floor dweller whenever possible. However as I have gotten older it’s more and more difficult to be comfortable for long. So, when I settled onto the Buttafly for the first time, I was amazed and delighted at how incredibly comfortable I felt – and continued to feel afterwards – light and balanced and effortless.”
