Ferm Living Catena Sofa Armrest Left - L400

The Ferm Living Catena Sofa Armrest Left L400 brings that signature low-slung comfort to larger spaces with its generous proportions and made-to-order flexibility. This left-side armrest module belongs to the L series, which means you get the full 108cm depth that lets you really stretch out and get comfortable - it's perfect for people who like to curl up sideways or need that extra room to truly relax. Available in their full range of upholstery options from natural cotton linen to rich velvet and textured bouclé, you can customize it to match your existing decor or create something completely fresh. The whole Catena concept comes from those gentle catenary curves - the natural shape a hanging chain makes - and that inspiration really shows in how inviting and embracing this piece looks when it's part of your seating arrangement.

At 138cm wide and 76cm high, the L400 provides substantial presence without dominating your room the way some oversized furniture does. That extra depth compared to the S series makes a real difference when you're actually using it - there's room to sit properly with back support, or to turn sideways and lean against the arm with your legs stretched out. The microcellular foam construction means the cushioning stays supportive over time rather than developing permanent impressions, and the modular connection system is designed so you can add center sections, connect to other modules, or reconfigure everything when your space changes. Whether you're building a complete sectional or just adding onto existing pieces, this left armrest anchors the whole setup while providing that perfect corner spot everyone gravitates toward.

Ferm Living has been perfecting this balance between style and real-world functionality since 2006, working from Copenhagen but collaborating with skilled manufacturers across Europe. The Catena collection represents their understanding that modern furniture needs to adapt to how people actually live - spaces that need to work for both quiet evenings and social gatherings, pieces that look sophisticated but aren't precious about daily use. Made in Italy with attention to both comfort and durability, each module reflects their commitment to creating furniture that enhances your space without demanding you change your lifestyle around it. They've built their reputation on pieces that age gracefully and stay relevant as your needs evolve.
