About the Buttafly

Hi! I’m Louise James (Tilly to my friends) and I have designed the Buttafly for your health and well-being.

Quite simply, I am passionate about helping everyone find the key to unlocking their full potential through physical awareness and believe that unraveling our postural habits can have a transformative effect on how we feel about ourselves, the world and our place in it.

I have more than 30 years’ experience as a Chartered Physiotherapist and have always enjoyed keeping fit and healthy – running, cycling, swimming, squash etc. But for all this, I have never been very supple and so when I started Yoga in 2005, I was incredibly challenged by sitting cross-legged on the floor. Ironically, the Sanskrit name for this position translates to “easy pose” but like so many, I struggled to get comfortable or sit well, and mostly found myself slumping, making it difficult to breathe properly and causing my back to ache. Sitting on a regular Yoga block didn’t help either – still I slouched!

So with my background in anatomy and ergonomics I set about designing a solution. The result is the Buttafly. It’s angled upper surface and contours are designed to provide the ideal position for the pelvis to rest in neutral with the body weight being taken through the sit bones as they are designed to and the indent at the back edge avoiding pressure on the tailbone.

The fluid curves and its wedged-shape also make for a supremely versatile prop for use in Yoga and Pilates – or any situation where support is required to help make a position or posture more comfortable.

Perhaps it most unique function, however, is as a device to off-load the spine in supine lying, providing an opportunity for the body to unwind – this is explained fully in the section Buttafly for Back Care.

Buttafly has achieved accolades from fellow physiotherapists, osteopaths, chiropractors, craniosacral therapists and practitioners of Yoga and meditation around the globe. and is proving to be an invaluable tool for back care and for sitting balance exercises by people who face all kinds of physical challenges, including Multiple Sclerosis and Parkinson’s disease.

Sit well, feel well, be well!

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.


The EASIER you make it for the body to sit comfortably in cross-legged position, the better. When the body is comfortable, the nervous system relaxes and this has a profound effect on every aspect of our being, releasing tension and  re-establishing optimal alignment with little or no perceived effort.
Sitting on blocks almost higher than you might think you need can really help the body to relax and open so that with in no time at all you can then sit on a lower support comfortably and with good posture too.

“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!”

“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.”
