Which statement is true regarding typing posture?

Maintaining proper typing posture is essential for both comfort and efficiency while working at a keyboard. Having the feet flat on the floor provides a stable base that helps with posture alignment and balance. This positioning allows the hips to be at a right angle and helps support the lower back, promoting a healthy seating posture. When the feet are flat, it reduces strain on the legs and back, which can prevent discomfort and potential long-term issues associated with poor ergonomics.

In contrast, having feet off the ground, crossed, or elevated can lead to a range of postural problems. These positions can create instability, cause awkward angles in the body, and may lead to fatigue or discomfort over time. They also can interfere with effective blood circulation. Therefore, ensuring that feet are planted firmly on the floor is the best practice for typing posture.
