1. When choosing upholstered furniture, pay special attention to the materials used for the frame, cushions, and fabric. For example, for leather sofas, the contract should clearly specify whether it is full leather, half leather, or thick leather to prevent salespeople from misrepresenting half-leather sofas as full-leather ones. The frame is commonly made of hardwood (such as catalpa, oak, ash, or birch), and a mortise and tenon joint structure is better than a screw connection. For the cushions, pay attention to the standard of the sponge used; higher density is better, and the sponge should have good resilience. The fabric should have good strength; high-strength fabric is less prone to snagging, and the leather surface will not sag.
2. When buying a mattress, pay attention to the strength of the springs, the filling materials, and the fabric. Spring strength depends on the steel grade of the wire used; a higher steel grade is better, and manganese steel is a good material. Filling materials include cotton felt (or chemical fiber felt) and coir fiber; cotton felt has good breathability, while chemical fiber felt has better strength. It's best to choose fabrics treated to resist dust mites.
3. Pay attention to the sturdiness of the furniture structure. For example, when buying a sofa, you can use your hand to forcefully move the diagonal parts inward. If it shakes or makes creaking noises, it indicates that the structure is not sturdy.
4. Check whether the internal structure materials of the sofa or bed (mattress) show signs of mold or insect infestation; observe whether the furniture padding meets the number of layers and hygiene standards specified by industry standards.
5. The purchase contract must clearly state the materials (full leather, half leather), sample color number, etc. Note whether the sofa cover and bed cover fabric can be washed or dry-cleaned, so that there is documentation in case of disputes. Pay attention to whether there are any gaps or loose stitches at the fabric joints. Some fabric sofa covers are prone to shrinkage and deformation after washing.
