How to put down the sofa bed？

Speaking of the sofa bed, I believe everyone is familiar with it. So the question is, do you know how to put the sofa bed down? Next, let me briefly introduce the relevant knowledge of the sofa bed.

Different styles of sofa beds have different operating methods. If it is a folding back cushion type, first you only need to turn on the switch on the back of the bracket, then put the back in a straight line and turn the sofa cushion over. If it is the extension type of the seat cushion, you only need to pull out the hidden at the bottom and splice it into a flat surface, and then adjust the backrest to a suitable angle.
