This week, we celebrate the beauty of tension. Sling and suspension seats tighten leather into graceful arcs, trading bulk for line and lift. These designs rely on craft and precise engineering so the material does the work and the sitter feels supported without excess. For projects where comfort and presence matter in equal measure, each piece offers a refined study in restraint. AMBASSAD Mats Theselius Mats Theselius conceived Ambassad with a cool steel structure that sets the stage for a seat and back in riveted core leather pulled perfectly tight. The eyelets and fasteners are not decoration so much as a quiet exposition of how tension holds the form. Specify natural or dyed hides to tune the tone while the frame keeps the silhouette crisp. The result is a dignified lounge chair that reads both architectural and inviting. CB-570 SLING CHAIR BassamFellows Here, suspension becomes the comfort system. A wood and steel frame carries leather belting that cradles feather and down cushions, allowing the body to settle while the structure stays light. The proportions are generous, yet the visual language remains spare thanks to the floating sling. Pair with the companion ottoman for a relaxed club setting that still feels tailored. PK22 Poul Kjærholm Poul Kjærholm’s PK22 distills the sling lounge to its essence with a slim steel base and a firm leather seat drawn in tension. The geometry makes the sitter feel almost suspended, which explains why the profile remains a favorite for layered living rooms and primary suites. Available in refined leather options on a brushed steel frame, it brings clarity and ease to a space. PELLE Lorenz + Kaz Pelle plays a different chord in the sling family. A freely hanging core leather seat is carried by a round crossbar below the backrest, with an aluminum insert inside the leather that keeps the plane smooth and supportive. The semicircular back wraps gently, while the sitting surface stays taut and buoyant. Use it as a singular desk chair or group it for dining where comfort and craft must meet. GRASSHOPPER Fabricius and Kastholm Fabricius and Kastholm’s chaise uses a tensioned canvas cradle to hold loose leather cushions and a neck roll, set on a refined steel frame. The sling carries the body in a long, relaxed posture while the metal undercarriage keeps the line impossibly lean. For rooms that ask for a sculptural recline with true lounge performance, Grasshopper lands the brief with ease.
