Recently, because desk work has been making my shoulders and lower back really bad, I tried various massage sheets. After all, massage chairs are expensive and I don't have space for one. Among the ones I tried, the Fuji Medical Equipment one feels pretty good from shoulders to lower back. You can finely adjust the position of the kneading rollers, which is subtly convenient to match that day's fatigue level. It also has airbag and heater functions, and offers a lot of features for the price. However, it doesn't seem to work much on the buttocks. I really recommend this massage sheet for people who want to thoroughly loosen their shoulders and back. Also, the Atex one isn't bad either. It covers a wide area and has less pain, which is attractive. In the end, choosing based on the part that gets tired easily is the best.
