A dinner for 6, 8 or 10? Nestable or stackable stools or chairs can disappear in a corner after a meal. A clever idea for small kitchens in particular. Low prices At Fly, the creators declined for the back to school their "Tulip" chair (79 €), round boilers and translucent seat, in a fluorescent version and always stackable: "Tootsie" (39 €). Recognizable by its square backrest pierced with holes, the Ikea "Jules" stacking chair is also a best seller (€ 39.95). The Swedish giant also offers a selection of stools at unbeatable prices ("Evert", € 3.50). Without forgetting the mythical "Tam Tam" stool, stackable and removable, at a very low price in most major brands (around 20 €, Alinéa, La Redoute). Pop lines Elmar Flötotto thinks of the whole family. Light and ergonomic, its "Mosquito" chair (Neunzig Design, € 315), with seventies lines, is ideal in the kitchen or as an office chair! Always a retro trend, Sentou reissues the legendary molded chairs "La Fourmi" and "Série 7" by Swedish designer Arne Jacobson (430 € each). Unsuspected, once stacked, the Irish stone stools balls form a real sculpture with rounded shapes (XL Design, 150 €). Khaki, black or red: coordinate the colors to create your 70s-inspired column. Children's models Your children invite friends for their birthday party. The designers have fun imagining original, light and stackable seats. This is the case of Javier Mariscal, who created for Magis Collection Me Too a tree-shaped chair in the colors of the four seasons, suitable for indoors or in the garden (€ 33). The German Elmar Flötotto, creator of contemporary furniture for children and adolescents, also offers several design and ultra-practical models. For example, his little "Wait" chair, in polypropylene with flashy colors (49 €).
