    Abstract: A carpet sample display rack has a curved supporting surface made of flexible wood, hard-board or the like, which is located to the rear of an inclined platform on which is supported a stack of carpet samples. The edges of the samples are secured on two parallel bolts connecting the platform and curved surface. The bolts also control curvature of the curved surface. The carpet samples can be flipped over the curved surface from the platform.
