Stockholm 2016: a group of students from Helsinki's Aalto University have designed and built a collection of chairs using a single material: black-stained solid ash wood.

The Product and Spatial Design MA students presented the furniture pieces at the Greenhouse exhibition for emerging talent at Stockholm Furniture Fair 2016 earlier this month.

Fourteen chairs and accompanying pieces of tableware were designed to be displayed in a cafe setting named Chat Noir.

"The cafe is a culturally significant place, for it is here where people – regardless of their social standing – can meet, share and develop daring, artistic and political ideas," said the group.

Each student was restricted by the use of stained-black ash – with sections of eight- by 24- millimetre and 24- by 24- millimetres – but was given freedom to experiment with shape and pattern.

This resulted in a series of simple but sculptural chairs, including pared-back designs by Laura Väre, Collin Velkoff and Mari Laajasalo.

Both Mette Kahlos and Daniela Weintraub used circular elements to form backrests for their chairs, while Andre Pozusis opted for a triangular back.

Sara Kokko's Rib chair and Lasso Alestalo's Piano design feature angled slats that are alternated in opposite directions to create uneven seats.

Soon Yeon Shim and Annamiia Suominen have arranged the lengths of wood to form geometric patterns on seats and backs.

Areas of Shim's design are filled in with extra batons, while Suominen has created a more open lattice.

Antonio Gurrola produced a tighter grid from thinner elements to make the flat surfaces for his chair.

Jakko Hyvärinen decided on a simpler arrangement, using vertical slats as a back and a perpendicular row of thinner ones for the seat.

To supplement the cafe setting, Erin Turkoglu designed black ashtrays and Saija Halo created a set of espresso cups.

"Using creativity in a successful way requires experimentation," said professor Jouko Järvisalo, who led the project.

"A significant part of experimentation is exploring materials, structures and principles, which cannot always be immediately put into practise."

Students at Aalto University School of Arts, Design and Architecture embarked on a similar project in Stockholm last year, when they created a range of chairs using blue plywood.

A group studying on the institution's Collaborative and Industrial Design course also imagined five new concepts for coffee machines and other household products in September 2015.

Stockholm Furniture Fair took place from 9 to 13 February 2016. Other seats on show included Färg & Blanche's collection of sofas and chairs made by stitching wood and fabric together.
