Seat size: It is important to check the width and depth of the chair, as this can give you more comfort, for example, you should check that the width is at least 40 or 50 cm, while the depth should also be enough wide if tall. You will be able to support all your thighs on the chair.Armrest height: It is important that the armrests of this chair are high enough to support the elbows and forearms without straining the shoulders. The most recommended thing is that the height of the handrail is adjustable.Seat height: It is also recommended to adjust the height of the seat since not all have the same measurements, and the models usually allow an adjustment of 40 to 52 cm from the ground. However, the ideal height allows the feet to rest flat on the floor, on the thighs and arms.Good lumbar support: It is important that you check that the lumbar support pillow is as comfortable as the lumbar arches and it needs support, so make sure that the lumbar pillow has the correct curve to improve the posture of the back.Lining : It is also important that the lining material is thick and padded to improve the feel of the wearer. Nylon and genuine leather are best because they allow sweat to escape, but you'll also find other materials, such as canvas and canvas combos, faux leather, mesh, and more.
