A training desk is a table designed specifically for activities such as training and meetings. It has characteristics such as durability and ease of movement, which can meet the needs of different groups of people. Training desks can be classified into various categories based on their materials, structure, and other aspects. Below will be a brief introduction to the classification of training desks.
1. Material classification
The materials of the Training Chair mainly include wooden boards, PVC boards, etc. Training desks made of wood usually have strong stability and durability, making them suitable for long-term meetings or training activities. The training table made of PVC board has certain safety performance and is generally more lightweight.
2. Structural classification
The structure of training chairs mainly includes single tables, combination tables, etc. A single chair is the most common training table, and each training table is independent and can be adjusted as needed. Combination refers to the combination of multiple seats together, usually in the form of geometric shapes or rows, suitable for use in large training venues. A stackable table is a training table that can be folded and placed together, saving space and facilitating storage and handling.
