They recall Japanese designer Shiro Kuramata's 1976 Glass Chair, which was bonded together with glue to give the appearance of floating in the air.
Kuramata was prompted to create the furniture after watching Stanley Kubrick's 2001: A Space Odyssey, and finding himself disappointed by the film's sets – which relied on existing furniture, rather than new designs.
"Almost invisible, these planes, without tangible support, hang in the air," said the designer, who began experimenting with glass during his time at Design Academy Eindhoven before starting his own studio in Amsterdam in 2014.
The Ombre collection is completed by a pair of curved glass screens. A taller version is made from clashing gradients of pink, orange, blue and green, while a smaller screen features pastel pink that fades into orange.
Other unconventional furniture shown in Milan this year included a collection of globular seating based on mushroom caps, and a collapsible wooden stool made from "programmable wood".
