There are numerous armchairs and sofas for lobbies and lounges, but those for narrow spaces such as corridors, elevator lobbies, and entrances are difficult to find. Therefore, a compact chair was devised to fit in those niches, for passersby to rest in for a spell or in which to have casual conversation.
Attempts to make an armchair small normally leads one to think of gradual elimination of the backrest to create a bench-like furniture piece. But casting the backrest as the star to which the seat is adjoined yields a design less about sitting and more about leaning against a grand backrest. Such a design takes up minimal space while offering to the chair's occupant a bit of calm and security.
The backrest and seat are independent parts, with shallow and deep seats and lower and taller backs available for use in combination according to the size of the space and degree of privacy desired.
