This set is made of fabric. The filling material for the backrests and armrest cushions is holofibre. To transform the sofa into a bed the Sedaflex transformation mechanism is used. Sedaflex is the name of the French-produced double-bed mechanism. This transformation mechanism is equipped with a 10-centimeter spring mattress. The frame of the products are made of solid wood, plywood and boards (woodfibre and particleboard). To add to the comfort, under the seat cushion on the frame is attached a metal spring in a snake form. The foam is glued to the underlying frame and the upholstery is stretched over it. The supports are made of solid alder. All the furniture is packed and prepared for self-assembly with clear instructions. All the furniture is brand new and ships in its original packaging.
