Provided is a sawhorse including two rigid frame members pivotally articulated to one another. Each frame member includes two legs wherein at least one leg of each frame member is an extendible leg including a support leg portion, an extension member coaxially extending therewithin and a locking mechanism actuatable by one or more manipulation member. The extension member is displaceable between a fully retracted position and a fully extracted position. The arrangement is such that extraction of the extension member is facilitated without requiring manipulation of the manipulation member actuating the locking mechanism while the retraction displacement of the extension member is facilitated only upon manipulating the manipulation member to actuate the locking mechanism to thereby allow retraction of the extension member into the support leg portion.
