Problems solved by technology
The backrest of the fitness chair is movable, and the angles of the backrest and the seat cushion can be adjusted to meet different needs. However, the adjustment must be carried out in advance, that is, the plug-in pin should be inserted into the adjustment hole according to the needs of the user before taking the seat. Sometimes you may have to try inserting it several times, which is troublesome, and this angle is only suitable for the adjuster, and it may not be suitable for others, so you need to adjust it again. In addition, the structure of this adjustment angle is more complicated
