Step 2: Four Corners Make It a Box

Assemble your box according to the photo below. The PVC fits together tightly enough to frame the box, but you can still fold in the side walls and stash your box behind a door. Note the dual T-joint configuration on each corner post: We used the upper set to hang the sides and the lower set for the top, but you're free to experiment. However you build it, make sure to jam the pipe firmly into the T-joints - we tapped ours in with a hammer.

When you're done, you can flatten your tent and stash it under the bed.
