Is Core-Tex Sit suitable for larger people?
Yes, but there is a size limit.  Although the sitting area is only 14”, the buttocks can be larger than that because the “sit” bones are the primary contact point.  For heavier and larger individuals, it is recommended to use Core-Tex Sit with a chair with minimal or no padding. This will prevent Core-TexSit from sinking into the padding and the padding interfering the Core-TexSit’s motion.
