Most seating furniture is designed to more or less stay permanently where they’re located, but some spaces require chairs that can be added or removed, sometimes even at a moment’s notice. In order to conserve space, some of these chairs can be folded while others can be stacked on top of each other. One common trait between these two different designs, however, is that they either already come in a single inflexible piece or have to be assembled with much effort. In this agile and fast-paced world, neither seems to be an ideal condition, and this sustainable design offers an alternative that eases the burden of setting up each chair and doesn’t take up space when you don’t need them for the time being.

Designer: Martini & Dall’Agnol

Stackable chairs aren’t exactly novel or uncommon, but the majority of those tend to have a limit before they start tipping over because of the overall form of the chair. The Stack chair, in contrast, was designed especially with that use case in mind, and thanks to its compass-like four-legged base, you can stack the chairs almost to infinity, at least in theory. Of course, you’ll be limited by how much vertical space you have and how high you can safely reach, but it’s reassuring to know that there is enough leeway there for you to stop worrying about dozens of chairs taking up precious space when not in use.

That’s not even the most impressive thing about the Stack chair, though. The design comes in only two parts, the base and the shell, and these two parts can be joined by simply snapping the base underneath the shell’s uniquely designed rim. With just a snap, the two become a single and stable piece of furniture, simplifying not just the manufacturing process and assembly but also shipping.

This fastener-free design also lends itself quite well to customization, as you can mix and match different base and shell colors or even materials. By default, it comes with a polypropylene shell, but it can also be made from wood that’s then upholstered with fabric, leather, or other materials. The chairs can be made to match any style that your space requires, and not just with a single color either.

The choice of polypropylene wasn’t made on a whim either and was intended to help make the chair not only long-lasting but also recyclable. In addition to being space-efficient when it comes to storage, the Stack chair also aims to be efficient in manufacturing, packaging, and transportation, leading to a more sustainable product overall.
