Sperto is available in four different colours, each with its own design. For example, Brick has more reddish tints in it, while Sky has more shades of blue. And of course, you can easily guess the predominant colours in the Bronze and Concrete versions. There are various options in respect of size and shape as well. All four colours are available in two rectangular versions (200 x 300 cm and 240 x 340 cm) and a round version, which is 280 cm in diameter.
