Wooden bookshelves are better. There are many kinds of bookshelves in the market with different styles, which are suitable for bookshelves of different ages. The materials of bookshelves are mainly divided into four categories: plastic, metal, glass and wood. Plastic bookcase: Plastic is a synthetic material. Although it is light, it is mostly harmful to health, and it is easy to scratch and damage. Metal bookshelf: The advantage of metal bookshelf is durability, but the biggest problem is its own weight. This makes moving and handling a big problem, even the hollow frame is much heavier than other cabinets. Glass bookcase: the glass material itself is fashionable and beautiful, and the visual effect is good, and there is no environmental problem to worry about in other bookshelves. However, the glass bookcase has a big disadvantage that fragile fragments are easy to hurt people, and there are many non-fragile ones, such as plexiglass and tempered glass. But this kind of glass is mostly used to build or make some small quilts, and this kind of bookshelf is quite expensive. From a practical point of view, it is not recommended to use glass, but if it is used as an ornament, the glass bookshelf is still a good choice. Wooden bookshelves: Wooden bookshelves are the most common bookshelves, which are made of many materials, such as plates and solid wood. Common wooden bookshelves are mostly MDF, and the quality is not as good as solid wood and high density. However, the cost is not high. Solid wood bookcase lies in texture and beauty, but it is more expensive. However, it is not recommended to buy wooden bookshelves made of other materials because of their great environmental risks. So from the above analysis, it seems that wooden bookshelves are better.
