Regardless of the material of the lounge chair, you need to pay attention to the rationality of the design when purchasing, and pay attention to the following three aspects.
First, don't choose a chair with a high sitting surface, because the sitting surface is too high, so that the legs are suspended, not only the leg muscles can not relax, but also the back muscles are in a state of tension, which does not achieve the relaxing effect. It is also impossible to choose a chair with a low sitting surface, because when the sitting surface is too low to the knee angle, the pressure is too concentrated on the abdomen, which may cause discomfort.
Second, do not choose a chair that is too wide. The width of the seat is too wide, and the two arms must extend outwards, which is prone to fatigue.
Third, the height of the backrest is preferably able to reach the position of the support head to relax the neck muscles.
