The Brianna Beam is constructed of wood with 1/4" rubber cell padding on top and is covered with brown suede. It is 10 cm wide (the same as a competition beam). Simply slide the beam down into the legs for a sturdy and safe base. No tools needed for assembly! With an innovative connection system, two or more beams can be connected together to create one 16' long beam. Order the optional Beam Legs to increase the height of the beam another 6". Again, no tools are needed, the beam legs simply hook and loop together.
