If you're observing the Twain Chairs pair in its stacked arrangement, you likely wouldn't assume that it separates into two. Besides what appears to be a reinforced structure with extra support in the backrest and the legs, this compound piece of furniture looks like it could serve as a relatively normal dining chair.
But if you were to grasp the lower rail of the backrest from behind and pull it out, you would discover that a smaller task chair emerges. Its seat is nestled beneath that of the larger furnishing, and when the two stand independently, you'll notice that they're both complete objects with minimalist assemblies. The Twain Chairs prototypes have been made from solid ash wood and would be ideal for small rooms that occasionally demand overflow seating.
