Apina’s sofa assembly system gives the sofa’s design the freedom to change and perfectly fit the space of different rooms. The goal of our design is to maximise the usability of different sofas by offering various sizes and types of sofa units, from single-seater and two-seater sofas to sofa beds (1P, 2P and B). Each sofa unit uses a solid wood frame for long-lasting durability. Each sofa unit is assembled using a mechanism that allows the different parts of the unit to freely attach and detach. The sofa design can thus be modified multiple times without compromising its durability. The seat cushions and sofa pillows are available in both fabric and PVC.
