The Leonard seamless chair has an upholstered backrest and seating surface and four wooden
legs. Despite the simple look, the chair went through a number of changes to reach this current
design. The chair’s original design had a similar side design at the top, which is the seating surface.
The design of the back support over an extension of the seating surface dramatically changes the
image of chair. Despite the simple design, the stitch line of the seating surface is a single stroke.
The surface of the back support and back surface are made up of two surfaces. The side surface of
the seat connects to the back surface, and the back surface draws a gentle curve that extends to the
surface’s stitch line on the back support. By using soft curves to create several surfaces, despite its
simple, seamless structure, we worked behind-the-scenes to find the perfect relationship between
the back support and seating surface from past complicated changes and production processes.
While the rear legs rise sideways in a straight line, the back support leans gently backward against
the straight line rising from the legs and drawing a line that links naturally for a comfortable fit.
In addition, the seating frame, which supports the seating surface while connecting the seating
surface to the legs, is chamfered so that the legs and seating surface connect in a gentle curve. By
accumulating the subtle details, we wanted to design a simple chair with dignity in its simplicity.
The side line connects the back support to the upholstered arms that go straight up from the front
legs. The line draws a gradual arch sideways and connects to the top line. The chair is formed with
these organic curved lines and surface. We were aware of the combination of a line that swings and
flows from the arm to the top of the back support and to the opposite arm. For the top of the backrest
and armrests, with a single pinched stitch line, a curved line swings repeatedly from the point where
the line rises from the armrests to the back surface to connect to a single line. The shell is made up
of curved lines so that the armrests and back support look slim but voluminous without increasing
in thickness. Because the relationship between the thickness of the legs and the shell determines the
chair’s overall lightness, we adjusted the overall thickness to avoid a heavy look. The armrests rise
from the stitch line at the center of the armrests. This line goes around the top line of the shell and
connects to the legs. A single piping on the side links the boundary line of the shell and legs.
The Leonard swing arm chair embraces a curved line like a slow waltz. We wanted to value edgy,
mature dignity without making it too soft. When seated, both arms rest naturally on the armrests.
The shape of the seating surface narrows from the front to the back and is designed to gently wrap
around the back.
