Materials & Craftsmanship
36 kg/m³ HR foam on an E1-grade plywood base, wrapped in OEKO-TEX® Standard 100 upholstery — the build behind every compressed sofa.
Quality From The Inside Out
Materials engineered for compressed-sofa performance
Every KCK.CASA sofa is built from the core outward in our own Foshan factory — certified upholstery, high-resilience foam, and a reinforced frame — then vacuum-compressed to a fraction of its size for effortless global shipping. Here is what goes into every piece.
