My particular model sports a clean, white plastic seat covered by a gray foam cushion that is tastefully decorated with a modern and minimal design of lines and circles — something you'd expect to see more in an art gallery than on a baby product.
The samples are afterwards sent to the Algalita Foundation, which analyzes each sample and classifies all the materials found in them, separating plastics by size, type (lines, film, fragments, foams, pellets) and color.
