The GRS Fento Board is the latest ergonomic knee brace. This product was specially developed for extra mobility: you do not tie this kneepad around your knees and the lever on the top makes it easy to move it around. The GRS Fento Board has the perfect weight: light enough so you move around easily and heavy enough so it does not move while kneeling and it does not blow away when used outdoors. It is also hard-wearing, breathable and includes a strong non-slip bottom and a wide surface for extra stability. Of course, the GRS Fento Board has the ergonomics you have come to expect from us: the Ergonomic Wedge ensures proper pressure distribution over the lower leg, preventing knee and back pain.
