Assemble a 3-foot section of pipe by connecting three 1-foot sections of pipe with a T connector between each segment. Place a three-way corner connector on one end of the completed pipe section. On the other end, place a four-way connector. Repeat to create four identical segments.
Create a rectangular shape from the pipe sections. Connect two of the pipe sections with an 18-inch segment of pipe between each vertical opening on the three-way corner connector. Repeat with the other two sections. Connect the two rectangles with 30-inch pieces of pipe between each horizontal opening of the corner connectors to create a box shape.
Create the back of the chair by placing a 1-inch segment of pipe in the four-way connectors on the top two pipes. Place an elbow connector, curving upward, on the end of each 1-inch section. Place a 36-inch section of pipe in the upward curving opening of the elbow connector. Place another elbow connector on the opposite end, and another 1-inch section of pipe. Place a three-way corner connector in the end of the 1-inch section.
Fit a 48-inch section of pipe into each of the other openings on the three-way corner connectors. On the bottom of the vertical pieces, place another three-way corner connector. Connect the openings that face each other with a 30-inch section of pipe. Connect the remaining connector openings with two 20-inch sections of pipe.
Fit four 12-inch sections of pipe in the horizontal openings of a five-way connector.
Place a 24-inch section in the vertical opening.
Fit another five-way connector on top of the 24-inch section of pipe so that four openings branch horizontally outward.
Fit four 12-inch sections of pipe in the horizontal openings.
Place a round piece of glass, plywood, or other flat material over the top of the 12-inch pipe supports. This material serves as the tabletop. If desired, secure the material with an adhesive.
