Ferm Living Catena Sofa Armrest Left - S400

The Ferm Living Catena Sofa Armrest Left S400 starts your modular seating journey with that perfectly relaxed, low-profile style that makes any room feel more inviting. As a made-to-order piece, you get to choose from their extensive fabric collection - from classic cotton linen in off-white and natural tones to luxurious velvet and textured bouclé options that let you create exactly the look your space needs. This left-side armrest belongs to the S series with its more compact 93cm depth, making it ideal for apartments or rooms where you want substantial seating without overwhelming the space. The whole Catena design takes inspiration from catenary curves - that natural U-shape chains make when they hang - and you can really see it in the gentle, embracing silhouette that practically invites you to curl up and get comfortable.

What's smart about the S400 is how it manages to feel both cozy and sophisticated at the same time. At 119cm wide, it gives you real armrest support and corner space to lean into, while the 76cm height maintains that laid-back "low living" vibe Ferm Living is known for. The microcellular foam filling isn't just about initial comfort - it's engineered to keep its shape and support over years of use, so you won't end up with saggy, tired-looking cushions after a few seasons. The modular system genuinely works too - you can connect center modules, add the matching right armrest, or even reconfigure everything when you move or your living situation changes. Whether it's your main seating spot or part of a larger sectional setup, this piece adapts to however you actually use your space.

Ferm Living has spent nearly two decades figuring out how to make furniture that works with real life rather than against it. Based in Copenhagen but working with skilled manufacturers across Europe (these modules are crafted in Italy), they've developed this approach where style and practicality aren't competing priorities. The Catena collection represents their philosophy perfectly - it's elegant enough for design-conscious spaces but comfortable and durable enough for daily family life. They understand that the best modular furniture gives you freedom to change and grow rather than locking you into one configuration forever, which is why pieces like the S400 have become staples for people who want quality seating that evolves with their needs.
