I dont know about that Co. either but I have a Joanns cutting table that was on sale for 59 dollars and I use it to clamp my quilts on.
Clamp down the middle first and pin then just move the whole thing to one side and clamp and pin then to the other side. It works for me.
I just cant get on the floor anymore so this is a great solution for no bending over or sitting on the floor.
