In the 2000s, the pezziball arrived in German offices and for a long time seemed to be an all-round solution for the lack of movement at work, including back pain. In the meantime, only a few people still work with a sitting ball under their butt and most balls are gathering dust in storage rooms. Unjustly? How does it really look on the basis of facts? Compared to an office stool, such as the Aeris Swopper, is the seat stool perhaps a good alternative after all?
Here we take a closer look at both seating options and show you the advantages and disadvantages:
Check No. 1: Individual setting options
Here, the Pezzi ball has clear disadvantages compared to the Aeris Swopper swivel stool. Although the seat ball is available in various sizes (approx. 45 to 95 cm in diameter), you cannot adjust its height individually and thus cannot optimally adapt it to your desk or your body size.
The tension and thus the swing depth for a good sitting feeling cannot be adjusted "quickly".
With the Aeris Swopper office stool, on the other hand, you can roughly adjust the chair to your needs in the first step thanks to the four different spring leg variants:
Standard spring leg (for body weights between 50 and 120 kg), Low (for desks lower than 65 cm), High (for heights over 185 cm) and Light (for people weighing up to 50 kg and heights up to 165 cm).
In addition, the individual seat height is then infinitely adjustable with a flick of the wrist. In this way, you can achieve an optimal angle between your hips and knees in no time at all.
Furthermore, the spring tension, i.e. the vertical swing up and down, can be individually adjusted to your body weight. And you can also adjust the lateral mobility of the work stool to suit your personal preferences.
The Aeris Swopper is thus clearly superior to an exercise ball.
What is a pezzi ball?
The name PEZZI is protected and belongs to the Italian manufacturer of gymnastic balls, Ledragomma. A PEZZI gymnastic ball, or Pezziball for short, is actually a large gymnastic ball, originally from that manufacturer.
Today, the term Pezziball is a deonym for a large gymnastics ball and is also used for balls from other manufacturers.
Check No. 2: Security
In terms of safety, the pezzi ball has to accept the biggest point deduction compared to the office stool. This is because most sitting balls are unstable and can easily roll away.
One second of inattentive sitting is enough to lose your balance and fall off the ball. Some manufacturers now offer a sewn-in floor ring to prevent the ball from rolling away, but this restricts mobility.
Another safety risk: You should make absolutely sure that the beanbag ball is made of a high-quality material to prevent it from bursting unintentionally. If possible, the seat ball should be made of an anti-burst system (usually manufactured with the composite material Crylon) or be labeled burst resistant or burst proof.
With the Aeris Swopper work stool, you don't have to worry about safety. The office stool is TÜV and GS tested and, despite its great mobility, is extremely tilt-resistant and stable.
The foot ring is available with castors or without castors (glides). In the version with backrest, castors and spring leg type Low (Swopper Work), the Aeris Swopper complies with the office chair standard DIN EN 1335.
Check No. 3: Design
In addition to the usual, mostly single-colored PVC seat balls, there are also gymnastic balls with covers made of various materials such as felt fabric, imitation leather, etc.. And also the colors range from classic to modern.
Disadvantage: the inflated gymnastic balls do not look very elegant, take up a lot of space and are considerably bulkier than an office stool.
With its design - the striking foot ring and the unconventionally convex-shaped seat - the Aeris Swopper is unmistakable among office stools. A unique piece and a classic.
You can customize the ergonomic work stool from over 50 cover and color options. And if you like, you can simply hide the stool under your desk at the end of the day.
Check No. 4: Environmental friendliness
This is where the Aeris Swopper clearly scores. Many exercise balls are made of PVC, which is harmful to the environment and health, and have to be disposed of as hazardous waste after a relatively short service life.
The Aeris Swopper, on the other hand, is manufactured by hand in Germany and therefore has an extremely long service life. If something does not work, you can easily replace individual parts and have it repaired.
Check No. 5: Price
Here, the sitting ball is in front, even if the prices vary depending on size, brand and quality. Cheap pezzi balls you can get from about 10 euros. The middle price range is between 50 and 80 euros. The higher quality brand models cost between 100 and 400 euros.
There are many reasons for the higher price level of the Aeris Swopper (from RRP 629 euros). The innovative work stool has a unique 3D movement technology, it is made of high-quality materials and manufactured in Germany (see also Check No. 4).
This ensures high quality and a long service life. In addition, the Aeris Swopper retains a high resale value for years and you have a three-year warranty. But in return you also get a high-end product.
Check No. 6: Mobility and ergonomic requirements
There's no doubt that you'll be much more active sitting on a high-quality Pezzi ball than on a conventional office stool. Because in order to prevent rolling away on the ball, you have to concentrate on a straight sitting posture and perform constant balancing movements.
Through the many small posture modifications you train the deep-seated muscles, especially in the lower back. At the same time, metabolism and circulation are stimulated.
However, the Pezziball is neither allowed nor suitable for permanent use in the office. Not allowed for safety reasons. Not suitable because of missing adjustment possibilities (see check no. 1-2). You can rather use the sitting ball for sports exercises in between or after work.
The Aeris Swopper office stool, on the other hand, offers you maximum freedom of movement - but user-oriented and suitable for office use. The work stool was designed so that you can use it all day in the office or home office without any problems.
How does it work? Aeris 3D technology allows you to move in all 3 directions with the work stool: forward and backward, left and right, and - uniquely for Aeris - also in the third dimension, up and down.
The effective up and down movement, called vertical swinging or "swooping," like walking or running, nourishes and relieves pressure on the intervertebral discs, keeping them fresh and elastic. This prevents and can relieve back pain.
Your muscles are strengthened so they can perform their proper function and keep your back straight. You do not need a backrest as an "artificial support". This is rather counterproductive for the muscle activity.
The lateral flexibility through the joint close to the floor also trains your muscles. All together it stimulates your circulation and metabolism and strengthens your back. You'll feel more alert and fit overall. And since muscle work also costs energy, you even burn extra calories on the side.
So you can easily sit on the Aeris Swopper all day without getting back pain or tension. The stool makes more than twice as much movement possible as a normal office chair. And is therefore ideal for long concentrated work in the office or home office.
The bottom line is that a sitting ball cannot replace an office stool like the Aeris Swopper or is not a real alternative to a work stool. Despite the different ball sizes, it cannot be optimally adapted to the body and offers too high a risk of falling.
You can use it as a temporary seat. However, it is mainly a piece of training and sports equipment that can be used in short sessions to strengthen the muscles of the back and abdomen.
To stay active all day long while sitting - and do so without any effort - you should invest in a high-quality, individually adjustable office stool like the Aeris Swopper. This will give you a completely new attitude towards life with less fatigue and more energy and quality of life. It's worth it!
