kentaro takagi bends recycled PVC tubes into contemporary chair

designer kentaro takagi has engineered recycled PVC tubes into the structural, comfortable ‘i.e. chair’. by splitting the plastic tubes and bending them using heat, the designer created the shapes needed for the different parts of the chair. he then produced wooden structural joints and surfaces, onto which the PVC tubes attach to.

the chair is light weight as it only uses hollow PVC tubes and light wood. the designer chose to sandblast the PVC tubes to give them a sophisticated finish, disguising the material’s ordinary surface. sliding the bent tubes into the wooden parts creates strong connections between both elements and provide rigid joints for safe seating.
