What is the Butterfly Seat?

The Buttafly is a revolutionary support to allow effortless cross-legged sitting with good posture. The Buttafly allows you to sit with good spinal alignment, when the body is comfortable, the nervous system relaxes and this can release tension and re-establish optimal alignment.

Why is your posture so important?

A slumped (forward) posture can increase downward pressure on the pelvic floor this can impact on symptoms of pelvic floor dysfunction including prolapse, bladder or bowel incontinence or pelvic pain.

Correct posture improves ones ability to correctly perform pelvic floor exercises. Your strengthening exercises will be most effective and successful with the correct spinal alignment.

Correct posture promotes deep abdominal muscle activity. Your deep abdominal muscles also play a role in supporting your pelvic organs and promoting bladder and bowel control.

Correct posture enhances diaphragmatic breathing. Diaphragmatic breathing exercises can help to promote appropiate helpful breathing patterns that enhance pelvic floor muscle activity.

The Art of Sitting

A basic understanding of anatomy will allow us to understand the intricacies of a good posture.


In simple the terms the spine has 3 curves designed to spread the load of the opposing vertical forces affecting the body – the downward effect of gravity and the upward ground reaction force which is created every time our foot strikes the floor: – backward facing curve called a lordosis in the neck (cervical) region – forward facing curve known as a kyphosis in the middle back (thoracic) area – backward-facing curve again in the low back (lumbar) area.

Sit Bones

At the bottom of the large and irregularly shaped pelvic bones are two prominences known as the sit bones – think of them like compact rockers. They are designed for sitting on!


At the base of the spine is the sacrum – a large triangular bone that is also jointed with the left and right pelvic bones at the large sacroiliac joints. The sacrum then supports the spine and the pelvic bones support the sacrum – the sacrum is the link between the spine and pelvis. The shape of the sacrum and the way in which it articulates with the pelvic bones means that in the neutral position it is angled forwards. The upper surface also slopes forwards contributing to the lumbar curve.


There is very little movement at the sacroiliac joints and any alteration in the position of the pelvic bones will result in a change in the angle of the sacrum and the shape of the lumbar curve. The pelvis is sometimes referred to as the pelvic bowl, and imagining this bowl as filled with water can help to get our heads around the next bit. If the pelvis is rotated anteriorly (tilted forwards) spilling water over the front edge, the angle of the sacrum and the lumbar lordosis increases; conversely when the pelvis is rotated posteriorly (tilted backwards) spilling water over the back edge, the sacrum becomes more vertically and the lumbar lordosis flattens out. Pelvic tilting (rocking) in this way is the same movement we performed when practicing cat and dog tilt in four‐point kneeling.

How the Butterfly Works

Sitting cross legged on the Butterfly seat with its gently sloping angle will cue the pelvis into a correct postural alignment. From there there are many different ways to use your Buttafly seat to help promote good posture, allow relaxation and promote good pelvic health.
