The height of your seat and desk will depend on your height and the type of work you are doing. However, here are some general guidelines to follow:

 

Seat height: The height of your seat should be adjusted so that your feet are flat on the floor, and your thighs are parallel to the ground. Your knees should be at a 90-degree angle, and your hips should be level with or slightly higher than your knees. This helps to prevent strain on your lower back and neck.

 

Desk height: The height of your desk should be adjusted so that your forearms are parallel to the ground when you are typing or using a mouse. Your shoulders should be relaxed, and your elbows should be at a 90-degree angle. If your desk is too high or too low, it can cause strain on your shoulders, neck, and arms.

 

If you're working on a computer, you may also want to consider the height of your computer monitor. The top of your monitor should be at or slightly below eye level to help prevent neck strain.

 

It's important to note that these are general guidelines, and you may need to make adjustments based on your specific needs and preferences. If you experience discomfort or pain while working, it may be a sign that your seat and desk height need to be adjusted.
