This is actually a very good question, and believe me, you are not the only one. I also started looking for a solution for my back a few months ago, because by the evening everything would start to hurt - my lower back, my neck, and then my shoulders. I worked in an office, sat at a regular desk, and although I did not have serious problems with my posture, I began to feel how the load on my spine was increasing. When I switched to remote work, I realized that I needed to change something, otherwise I would not last long. I started looking for desks with adjustable height, and, frankly, at first I thought it was more marketing than something useful. But the more I read, the more I was convinced that such a thing makes sense. The solution came when I ordered an automated standing desk from

To be honest, at first I doubted how such a thing could affect my well-being, but in practice it really worked. I started working standing, and then alternated it with sitting positions, and literally after a few weeks I noticed a difference. My back began to hurt less, and my energy at the end of the working day remained at the level as if I had just started working. Of course, it is important not just to sit or stand, but to change your position during the day. I can say for sure that after a few weeks of this approach, all my problems with back and neck pain almost disappeared.
