What material is good for the waist pad?

1, select arc cushion. A curved cushion is much better than a cushion without curvature and has enough strength to support the waist. It is best to choose a convex cushion, the size varies from person to person. The correct placement position is below the scapula to the buttocks, and you should choose the style that best fits your waist curve. Some cushions also have prominent radians on the left and right sides. Lin, a rehabilitation doctor at Taiwan Province Provincial Hospital, thinks that ordinary people don't need them. If you drive often, you can choose this kind of cushion, which is more protective.

2. Choose a cushion made of memory sponge or plastic board. Cushion materials on the market are divided into four types: mesh cloth, elastic cotton, memory sponge and plastic plate. Generally speaking, memory sponge and plastic plate have the strongest supporting force. There are also many people who use plush toys as cushions, and feel that the filled cotton used in them is soft and comfortable, but this material has a relatively small dispersion pressure and cannot be used by middle-aged and elderly people and people with pain. The mat doesn't count until you lean on it.

3. Pay attention when using the cushion. No matter what kind of cushion, you must rely on it to play a role. In addition, the buttocks should occupy the whole chair surface, so that the waist and back are completely close to the back of the chair and the feet are flat on the ground. This posture is the most labor-saving and comfortable, which helps to keep the blood circulation in the legs smooth. Short people can choose a thicker cushion. If you add a cushion, your hips can't fill the chair surface. It is suggested that you can stick your body on the back of the chair first, put a box under your feet, and your knees are higher than your hips. In addition to adding cushions, you can also reduce the chance of hunching by putting the chair near the table or the computer screen.
