An incorrectly sized keyboard can cause problems for the wrist, elbow and shoulder. Our ergonomic keyboards are thin so that the wrist does not overextend. Another important factor is the width; a keyboard that is too wide interferes with the use of the mouse, inducing a very open angle of the arm: this can negatively affect the joints, especially the shoulder. Our compact ergonomic keyboards or those with a numeric keypad on the left do not interfere with the use of the mouse and allow you to assume a correct posture while using the computer.
