It is easy to use as a product. This review focuses on assembly and disassembly. It is made up of a very large number of parts. There are 15 types of main body parts, and almost the same number of screws and other parts. The main body has a number sticker attached to each type of part, and the screws are packaged in a special plastic container so that you can tell which screw is which, so even a beginner can assemble it while looking at the manual. However, there are a few problems. The main points are as follows ① There are many similar parts, and if you don't leave the numbering stickers on, you won't know which parts are which, and it will be complicated to reassemble after disassembling for moving etc. ② It's difficult to assemble by yourself. We recommend that single people use the assembly service. It's impossible for a single woman to assemble it by herself. ③ The screws in the plastic container are sealed in with super-strong adhesive, so you can't open them by hand. You have to cut it open with a cutter or something (see attached photo. There is a possibility of initial defects, but it may be different for other people). The flip side of the difficulty of assembly is that it leads to the difficulty of disassembly and reassembly. If you are planning to move house, be careful. The moving company will take care of the disassembly and reassembly, but it is a delicate process
