An American report pointed out that the elderly should not only consider lighting and the ground, but also pay attention to the height of some furniture such as beds and chairs. Experts believe that if the bed is too high, the old man should lean forward when sitting down, and there is no armrest support, which is easy to lose his center of gravity; The chair is too low, and the center of gravity is unstable when getting up, which leads to a fall.

"In fact, the height and size of many furniture in the elderly rooms have specific requirements." Dr Yan Ribai from Peking University Health Science Center told the reporter. For example, the bed of the elderly depends not only on whether the height is appropriate, but also on whether the width is appropriate. The suitable bed height for the elderly should be 40-50 cm. Because people have different bodies, the height of the bed should be slightly higher than the kneecap of normal adults.

The width of the bed is 30-40 cm wider than when the elderly lie flat, which is convenient for them to turn over and stretch freely on the bed, which is beneficial to stretching bones and muscles, promoting blood circulation and relieving fatigue. The table of the elderly is slightly lower than that of the young, and 70-75 cm is appropriate. This is because most elderly people are dizzy. When reading, books are farther away from the eyes than young people, and the desk is slightly lower, which makes reading more convenient.
