Platform assembly

A platform assembly comprising:

• a platform extending in a horizontal plane and having a bottom surface;
• a vertical post having a width, as measured along a horizontal axis, and a length, as measured along a vertical axis, that is greater than the width, the vertical post having a lower end, and an upper end directly coupled to the bottom surface of the platform;
• a C-clamp comprising:
• a horizontal side at least a portion of which is coupled to the lower end of the vertical post;
• a first vertical side meeting the horizontal side at a first corner of the C-clamp and extending downward;
• and
• a second vertical side meeting the horizontal side at a second corner of the C-clamp and extending downward, the second vertical side comprising a threaded hole;
• and
• a screw comprising a handle at a first end of the screw and a shoe at a second end of the screw, the second end of the screw passing through the threaded hole of the second vertical side of the C-clamp and extending horizontally toward the first vertical side of the C-clamp, wherein movement of the handle causes the second end of the screw to further extend horizontally toward the first vertical side of the C-clamp such that the shoe and the first vertical side of the C-clamp frictionally engage a support structure when the support structure is positioned between the first and second vertical sides of the C-clamp.
