The E7Q provides a stable and height-adjustable desk solution due to its four legs, which offer a wide and steady base. Working on it eliminates the jiggle that is common with two-leg height-adjustable desks. You will notice the difference right away and appreciate the elegance that the E7Q offers. Four motors power the E7Q, allowing it to handle any load placed on the desktop while maintaining a smooth and steady pace and remaining as quiet as a mouse.
