The sofa is an indispensable piece of furniture for the living room. What should we pay attention to when we buy a sofa? Today, let Lefs Home tell you how to buy a sofa!
1. See if the sofa frame is strong, which is related to the service life and quality assurance of the sofa. Lift one end of the sofa and notice that when the lift is separated from the 10CM , the other leg is off the ground, and only the other side is off the ground.
