1. သုတ်သင်းမှုလုပ်ငန်းစာရင်းများနှင့် အရည်အသွေးများကို လေ့လာထားပါတယ်;
2. Design excellent products according to the existing materials, and make the best use of them;
3. 擅长使用各种新材料来提高产品质量并增加产品美感。除了常用的木材、金属和塑料外，还有藤、竹、玻璃、橡胶、布料、装饰板、皮革、海绵、FRP等等。然而，并非所有材料都可用于家具的生产。

Cafe Western Restaurant, Tea Shop, Tables and Chairs Purchasing staff restaurant dining table and chair - the application of table and chair materials also has certain selectivity, which should mainly consider the following factors:
1. 加工技术：材料加工工艺直接影响家具的制作，木材在加工过程中要考虑含水率的影响，如干缩、各向异性开裂和孔隙等；塑料要考虑其韧性、热塑性变形等；玻璃要考虑其热脆性、硬度等。
2. Texture and appearance quality: The texture and texture of the material determine the special feeling of the appearance quality of the product. Wood is a natural material with natural and beautiful texture, vivid image, good hand feeling, easy to process and color, and is the superior material for producing furniture. Plastics and their synthetic materials have the characteristics of simulating the texture of various natural materials, and have good coloring properties, but they are prone to aging and are susceptible to thermal deformation. With this, furniture is produced, and its service life and scope of use are limited.
3. 经济学：家具材料的经济学包括材料的价格、材料的加工劳动力消耗、材料的利用率以及材料来源的丰富程度。
4. Strength: In terms of strength, the grip strength and the tamper resistance and elastic modulus should be considered.
5.表面装饰性能：在正常情况下，表面装饰性能是指涂装、胶粘、雕刻、着色、熨烫、熨烫等的可行性。
