Furniture comes in various types and materials, and it's an essential part of every home. Choosing the right furniture can be challenging. According to Luo Xin, the executive deputy director of the National Furniture and Indoor Environmental Quality Supervision and Inspection Center, each type of furniture has its own "hidden strengths." If these key points are not properly addressed, the quality of the furniture can significantly decrease. Here’s how to identify good-quality furniture.
When it comes to glass furniture, thickness is crucial for safety. Glass furniture is prone to breaking, so a certain level of thickness is necessary. Tempered glass is the best option for larger pieces. It is much stronger and more durable than regular glass, with a higher load-bearing capacity. For example, 10 mm thick tempered glass can support up to 65 kg when placed on four corners. It is also heat-resistant, capable of withstanding temperatures up to 300°C. If dropped from a height of 80 cm, it usually won’t break. Even if it does, the fragments are smooth and won’t cause injury.
Plastic furniture is often lightweight and easy to move, but it's susceptible to aging and deformation. It’s important to check its load-bearing capacity before purchasing. For instance, plastic chairs should be able to support multiple people, and shelves should hold several items without bending. When using plastic furniture, avoid direct sunlight to prevent discoloration or cracking.
Solid wood furniture should be inspected for the joints. The quality of the wood—its species, origin, color, and age—is important. To maintain the natural look and feel of the wood, solid wood furniture typically uses a mortise-and-tenon joint instead of nails. Check that the joints are tight and well-finished, as loose connections can affect durability.
For panel furniture, environmental friendliness is key. Panel furniture is popular due to its affordability, style, and good quality. However, since it often involves painting and adhesives, it's important to check its eco-friendly rating. A simple way to test this is by smelling the furniture—if it has a strong chemical odor, it may not be safe. You can also ask the seller for environmental testing certificates. Another method is to touch the surface to ensure it's smooth, with no paint peeling or uneven texture.
Upholstered furniture, like sofas, requires attention to both structure and padding. The frame should be sturdy, as it affects the sofa's lifespan. Gently push the sofa to see if it feels stable. If it wobbles or makes noise, it may not be well-built. Open the cushions to check the metal or wooden frame for thinness or damage. The filling inside is also important—high-density foam offers better support and longevity. When sitting on the sofa, it should indent about 10 cm and quickly return to its original shape. Also, check the fabric for smoothness, even stitching, and consistent color, ensuring there’s no fading or uneven patterns.
