This is the Easy Writing Board from Balance Lab that I purchased last year. I bought it along with the Balance Easy (the Balance Easy itself has already been sold on Mercari), but I hardly used the study desk, so I'm putting it up for sale. There are official L and M sizes, and the one I'm selling is the larger L size. Retail price: 32,780 yen I think it's clean with no noticeable stains or scratches. It's useful for homework, drawing, and more. Below is a quote from the official website: ● Gentle on the body A new learning style. The Easy Writing Board was created with the desire to make a tabletop that is the most gentle on the body when used with the Balance Easy. When spread out on an existing desk in the dining room or living room, it instantly becomes a study space. It improves the learning environment, which often leads to poor posture during living room study sessions. ● Development Story The 10-degree angle, thoroughly derived. Living room study is now commonplace. What you often see is a posture where the neck is raised and leaning forward, putting a strain on the body. Poor posture can lead to a lack of concentration and a negative impact on eyesight. To improve these environments, we have conducted thorough research, verification, and monitor tests, in addition to our overwhelming sales record of balance chairs, and pursued the ideal angle. ● 10 degrees, not 20 degrees When we had people sit in the Balance Easy and conducted monitor tests on the angle of the tabletop, both 10 degrees and 20 degrees of the tabletop angle yielded good results. However, with 20 degrees, although good posture could be maintained, there were many voices saying that it put a strain on the wrist when writing and made it difficult to write. On the other hand, with a 10-degree tabletop angle, the results showed that it was easy to read and write while maintaining good posture. The 10-degree angle is the angle that came from everyone's voices. ● How to make a tabletop that is gentle on the eyes and neck? As we pursued what is gentle on the eyes, the angle of the tabletop naturally became important. Generally, when reading books or reading, it is considered easier to see when the angle between the line of sight and the tabletop surface is a right angle. However, if you try to bring the line of sight and the tabletop closer to a right angle, you have to tilt your body and neck considerably. The Easy Writing Board can reduce neck tilt by simply placing it on your desk and raising the height.
