This sofa is equipped with the Tick-tock transformation mechanism. To unfold the sofa it is necessary to remove the back cushions first. Holding the bottom front of the sofa, a slight movement up and forward is needed to push the seat forwards to be carefully lowered to the floor. The floating seat "steps" to the required folding distance without touching the floor. The backrest is then lowered into the vacant space. There is storage space for linen under the seat. The mechanism is simple to use, is durable, and provides a comfortable rest on a wide bed. 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.
