How much time do you spend sitting down? Do you know that the position of your pelvis affects that of your vertebral column ? Sitting incorrectly can lead to serious degenerative diseases such as spinal disc herniation, premature lumbar arthrosis and cervical arthrosis, as well as joint weakness (lumbago, etc.). You can do something about it!

We are all aware of the bones in our buttocks, we sit on them, but we do not know when they are positioned “correctly”.

Sitting on the Ischiobase makes you aware of your sitting position and helps good back support.

We can be more conscious of the way we sit and at the same time be better positioned on our ischiums. The ischiums are like “two little feet” upon which our pelvis rests. This allows the vertebral column to be aligned in the easiest, most effective (least tiring) and most correct way.

When we sit on a soft chair, the pelvis rests on a concave surface and the ischiums move closer together and the sacrum is " unstable " This is often the case with cushions, car seats and on planes. The sitting position on the Ischiobase respects the physiological distance of the ischiums and supports the pelvis better.

By stimulating our proprioceptive senses, the Ischiobase helps to find the best sitting position to support us. It encourages the distance between the ischiums, guaranteeing the stability of the pubis and sacroiliac joints.

By giving support to those whose ischiums are not too close (sometimes they are even too far apart), the Ischiobase has the opposite effect – relaxing the pelvi-trochanterian muscles which are responsible for this... in a similar way to proprioceptive insoles which, by restoring correct support, allow the automatic realignment of the arch and relaxing the muscles by reprogramming them...

The Ischiobase resembles a lens which can simply be placed on a seat. We have designed three different models so they can be used for all body types.

Its small size means it can be easily carried anywhere, in your pocket, in your bag, etc. Its invention and development is the result of joint research and experimentation between Véronique Donnadile, a GDS Method muscular chain kinesiologist, and André Theunis a Violin maker.
