A measurement device for determining the dimensions of a specific user in order to optimally configure a slatted bedframe for the user. The device has a plurality of cross members, each cross member measuring the height of a specific measuring point on the user, such as shoulders, waist, hips. The cross members are coupled to each other by a height-adjustment system that is based on the standard height proportions of the human body. Manually adjusting the height of one cross member, for example, the shoulder height, results in the hip and waist cross members automatically being adjusted to the appropriate heights. Pairs of calipers are provided on each cross member that are adjustable in width, for measuring the widths at the selected measuring points.
