What is the quality of the sofa in the world? Communicate with friends who have used it

Choose a sofa to see, sit second, and smell three:

Take a look: see whether the sofa fabric is strong, the color is consistent, whether the seams are neat, and whether the appearance is regular;

Second sitting: whether the sofa is moderately soft and hard, the height is appropriate, whether there is shaking, and whether the fabric is comfortable in contact with the skin;

Three smells: Approach the sofa and smell whether the sofa has the smell of glue or sponge.

Just look at the quality of the seam of the sofa, and see if there is a problem with the structure, which has little to do with it.
