Product news: these A-shaped stools by Japanese studio Torafu Architects slot together to make a bench.

Torafu Architects used basic 2x4 planks of red cedar to make the AA Stools, cutting them at an angle to form

trestle-like structures.

Each narrow stool can be paired with another to make a wider seat, or joined in sequence to make a bench of any

 length.

The stools also pack flat for storage and transportation.

They were made in collaboration with Ishinomaki Laboratory, a community centre established by designers in the

wake of the 2011 tsunami.

An auto repair shop in Tokyo, a concrete house designed for a resident in a wheelchair and a shelf with a secret

drawer that opens with magnets are among the other projects by the architects we've featured – see all our

stories about Torafu Architects.

Other stools we've featured on Dezeen lately include a three-legged design inspired by a Russian satellite and one

with interlocking legs like a puzzle.

AA Stool

Following "skydeck", this product is the second item made in collaboration with Ishinomaki Laboratory, which is ‘a

 place of creating something new’ for the community, established by designers and others in Ishinomaki City of

Miyagi Prefecture.

AA Stool is a simple stool made of 2×4 wood modules where the legs are cut at a slightly diagonal angle at both

 ends. Combining these leg pieces together allows the stool to stand, and at the same time provides support for

 the seat of the stool. A set is composed of two stools, which can be integrated together into one unit. It can

 be separated into individual stools as required for visitors' use or for within small spaces.

Stacking and lining up the stools lets the seat gradually become wider, yet it remains as compact as it can possibly

 be. At a height of 560mm, the seat is a little higher than usual chairs, which allows for a comfortable upright

sitting position. It is also convenient for those who work sitting on a stool. From the side, the stool looks like the

 letter ‘A’. Whether you are stacking or separating the stools, you can find a new use each time as your imagination

 lets you.
