The Wally Rebounder Advanced Rebounding System is a 34"x15" board supported on each end with a tripod.  The tripod base is about 24" depending on how far the legs are spread out. So about 12" of area is needed in the front, back and side of the board (1/2 of the tripod footprint).  To be safe, a 60" x 24" footprint is required for the Wally Rebounder.single board setup.We ship the board in a 37"x15"x6" box that weighs 21lbs (an extra 2 pounds if the Close-up Bounder Add On is purchased).
