If one thing’s as certain as death and taxes, it’s that leather will always be cool. Whether it’s a perfectly broken-in motorcycle jacket or a pair of soft tan midcentury chairs, a touch of leather is a fail-safe way to elevate your style. While the material isn’t new to the design world—it’s been integrated into interiors for thousands of years—its popularity hasn’t waned, especially in recent decades. (The 1960s, ’70s, and ’80s proved popular for leather—particularly in sofas and chairs.) Today, designers’ enthusiasm for the hide hasn’t waned and, in fact, their means of experimenting withits limits has only increased. Take Elliott Barnes’s Endless Summer II Bench, which employs Synderme, a mixed-composition product that uses recycled-leather cutoffs as a main component, or Francesco Balzano’s Murano Gueridon table, which flawlessly finishes an entire table with the natural skin. Bringing some lightness to the genre are English designer Faye Toogood, who had fun playing with color and shape in her Squash mirror for Poltrona Frau, and Fabiana Machado, with her Continuous chair—a seat that brings to mind the outline of a puzzle piece or hand-drawn maze. On the darker side, quite literally, is Gio Pagani’s Voyage d’Une Nuit bed: a high-impact sleeper fully covered in glossy-black leather.
