It is not a rug, it is a floor mat that you piece together from foam floor tiles. Each square, circle, and 4-point star is an individual piece and you can put it together in whatever configuration you like. It comes with enough pieces for a mat of 20 squares (as pictured, configured in a rectangle of 4 squares x 5 squares).
Each square tile is just 14" or about 35.5cm so if you put it together in a 4x5 tile configuration, it is 178x142cm.
