Abstract
Abstract The desk has a top member and two pairs of legs with each pair of legs including a front leg and a rear leg with the front leg effectively having a height greater than that of the rear leg such that the front edge of the top member is higher than the rear edge of the top member. The front edge of the top member has a length greater than the length of the rear edge of the top member such that the top member is generally trapezoidal in shape. The two pairs of legs are secured to the lower side of the top member near its two side edges respectively such that the front legs are located at the front of the desk and the rear legs are located at the rear of the desk and the distance between the two front legs is greater than the distance between the two rear legs. Two of the desks may be nested together by locating the rear legs and the rear portion of the top member of one desk between the front legs and under the front portion of the top member respectively of the other desk.
