This our our lap or table top frame. It has a solid oak base and rubber no slip on the bottom to hold the frame securely in place on your lap or on the table in front of you. The tops are made from oak and are rounded so the grippers are open and spread to hold your backing. If you have ever tried a flat top frame and had trouble with the backing staying on this is why. The grippers MUST be on a curve in order to work 100%, they will hold if stapled on a flat surface, but not as much as on a curve. Our frames are all top quality and we stand behind them 100%. This head swivels and tilts so that you can hook at the most comfortable position for you. It can also be added to the floor frame base to convert it to a floor frame! I can't say enough good things about our frames and neither can our happy customers.
