Chairidor - the hard but soft chair

Both hard surface and soft surface chairs have their advantages and disadvantages. This design merges them together. You sit on a hard slightly flexible surface, which is held by a larger stronger hard surface which is base of the chair, between these two surfaces is a 3rd material which is soft and works as a softener. This way, the surface the person sits on is hard, easy to clean, holding the body in the right pose, but still, it is way softer than a normal chair.
I codenamed the design Chairidor
