Sitting ball
A sitting ball, also known as an exercise ball or stability ball, is an interesting alternative when it comes to ergonomic seating. They are more playful than office chairs and, in terms of ergonomics, even better. When sitting on a chair, there is still a (small) static load on the body because you don't move. However, this is different with a sitting ball because you are constantly in motion.
What is a sitting ball?
An ergonomic sitting ball for the office is a round, inflatable ball used for sitting. Sitting balls are usually made of PVC material and are available in various sizes. The idea behind using an ergonomic sitting ball is that sitting on the ball forces you to maintain balance and use your muscles to maintain good posture. As a result, using a balance ball can help reduce back and neck pain and promote a healthy sitting posture. Sitting balls are often used in offices, fitness centers, and homes as an alternative chair.
A sitting ball has several benefits for your health and well-being, including:
Improved posture: Sitting on an ergonomic sitting ball can help you maintain good posture as you automatically sit upright to maintain balance.
Strengthened muscles: Using a sitting ball can help strengthen your abdominal and back muscles as you need to engage these muscles to maintain balance.
Reduced back pain: Sitting on a sitting ball can help reduce back pain caused by poor sitting posture, especially for people who spend a lot of time sitting at a desk.
Better blood circulation: Sitting on a sitting ball can help improve blood circulation as you constantly make small movements to maintain balance.
Increased concentration: Using a sitting ball in the office can help improve concentration as sitting on the ball keeps you alert and focused.
Variety of positions: Using a sitting ball can help alternate between different positions, preventing muscle stiffness and increasing productivity.
How long can you sit on a sitting ball?
There is no set time limit for using an ergonomic sitting ball, but it is recommended to gradually build up usage and alternate with a traditional chair. Start by using the sitting ball for 20-30 minutes per day and gradually increase the time up to a maximum of 2 hours per day. It is important to remember that using a balance ball is not meant to completely replace a traditional chair but rather to alternate between different sitting positions. It is also important to choose the correct size sitting ball to ensure comfortable and stable sitting, avoiding muscle strain.
What size sitting ball do I need?
The appropriate size of a sitting ball depends on your height. As a general guideline, the taller you are, the larger the sitting ball should be. Here is a guideline for choosing the right size sitting ball based on your height:
For a height up to 155 cm: choose a sitting ball with a diameter of 45 cm.
For a height of 155-165 cm: choose a sitting ball with a diameter of 55 cm.
For a height of 165-178 cm: choose a sitting ball with a diameter of 65 cm.
For a height of 178-190 cm: choose a sitting ball with a diameter of 75 cm.
For a height above 190 cm: choose a sitting ball with a diameter of 85 cm.
It is important to remember that these are just guidelines and the right size may also depend on your weight, body build, and personal preference. If you are unsure about how long to sit on a sitting ball or which size to choose, it's best to contact Ergo2Work for appropriate advice.
