Aeris Swopper Active Stool


What is it? The Swopper by aeris is one of the most well-known active sitting stools in the market. It was inspired by the idea of active sitting, which essentially means you move the chair whilst you sit.

The key is the movement is a centrally mounted spring, which facilitates three-dimensional movement. Many people describe the feeling as a gentle rhythmic bounce.

Who does it help? It is mainly used for work or hobbies. Individuals get the it for different reasons, but the two largest groups of customers are:

Those with back injury: One broad category of professionals has back pain and buys the Swopper stool because they like the idea of being able to keep their spine moving whilst also strengthening the muscles around the core.

Those with injury prevention in mind: Some individuals like the idea of staying gently active during sitting as a way of staying healthy and preventing back issues.

Adjustability Credentials:

Height: The Aries swopper can be adjusted for height, which means you can optimize your seat position for your height and the height of your workstation.

Active Movement: It has a tensioner adjustment, which means you can control the amount of free movement you have on the stool. If, for example, you have reduced core strength, you can reduce the unsteadiness of the seat and then gradually increase this as you get stronger.

Aesthetic Credentials:

It was originally invented in Germany in 1997 by Josef Glöckl to disrupt and improve the office chair market. Since then, it have been sold worldwide and won several awards for design and functionality.

Sustainability Credentials:

Nearly 100% of it is handmade in Germany, and the production facilities have been partly powered with solar panels since the early 2000s. It is made from recyclable materials, which have been awarded with environmental and health safety certificates. As a company, Aeris has started to convert its transportation fleet to electric vehicles.

Selecting Your Options

Spring Size: 

The stools have one-size seat top that fits most adults. The other consideration is the spring strut. The strut comes in 4 sizes, and the choice depends on your height and weight. Please see the options below:

  • Spring strut standard:As the name suggests, this spring strut fits most customers (body weight 50-120kg).
  • Spring strut high: This fits users from 50-120kg and is best for people who are over 185cm tall.
  • Spring strut low: This fits users from 50-120kg and is best for people whose desk is lower than 65cm.
  • Spring strut light:This fits lighter users from 35-50kg.

Castors Versus Glides: 

If you want to be able to move the stool around, we recommend castors. If, however, you need the chair to stay in place all the time, then we recommend glides (glides are effectively a base without wheels).

Frame and Spring Colours:

Frame and Spring: There are 3 colour options for the frame and spring, including white, light grey, and black. Please note that the spring colour must be the same as the frame colour you select.

Seat Fabric: 

There are 6 different fabric choices, which are normally selected based on aesthetics, cost, and function.

  • Artificial leather: Robust, cheapest fabric comes in black only. The Swopper covered in this fabric is also known as “the Swopper standard.”
  • Wool Capture and Gabriel: These fabricsare both natural fibres and so popular for people who prefer natural products. These fabric colours are more subtle and have been selected to fit in with home office colours.
  • Microfibre: This is one of the most popular fabrics used on aeris Swopper chairs for use in work office environments. Microfibre seat covers are engineered with ultra-fine fibres to be slightly softer, more stain resistant, and cooler to the touch. The Swopper with a microfibre cover is also known as “Swopper Classic.”
  • Felt fabric:This is one of the warmest Swopper seat covers. It is particularly popular for users who like a soft feel fabric for home. Felt is also surprisingly durable.
  • Artificial leather (Stamskin): For people who like the look of leather but don’t believe in using animal products, Stamskin offers a strong, elastic, and durable alternative.
  • Leather: The leather cover for the Swopper is known for its durability as a fabric and can last significantly longer than most other fabrics. Leather is tough but flexible, which makes it more resistant to punctures and tears.

Mesh fabric runner: The cushioning on the mesh fabric runner has been built with several separate layers to make it feel much softer. The cover is made of a lightweight and permeable mesh, which has thousands of tiny holes to make the seat feel cooler and more comfortable to use over longer periods. The mesh fabric runner Swopper is also known as “the Swopper Air.”

Research: There are no large, independent, gold standard RCTs on the long-term benefits of any chair brand that we know of. In the absence of the gold standard, we look to what information is available. Unlike many manufacturers, Aeris has taken the time to invest in several research studies since 1995. To see some more of this research, please click here.

From the small, short-term studies that have taken place, it has been reported that Swopper sitting has had a positive effect on posture, comfort, and concentration. Two studies also reported that Swopper sitting helped with back pain. Because these studies have not been repeated in larger, randomised controlled trials, it is difficult to generalise these results to a wider population.

Unverified reports: Unverified reports are reviews and case studies that we have found online. Whilst unverified commendations do not have the same scientific rigour and credibility as research, they can still offer some early insights into what equipment may be worth exploring in more depth.

What conditions does the Swopper help? We have found that most commendations for the Swopper come from people with low-back pain who like the motion of the chair and find it helpful in managing their discomfort levels. We have also seen a few reports of people finding the active movement on a Swopper helpful for stretching tight hip muscles whilst sitting.

How much has a Swopper helped? There is a lot of variation in how beneficial the Swopper is, and often, feedback is biased towards the extremes of experiences people have. Some people who shared feedback described the Swopper as having a huge impact on their comfort levels, whilst for others, the benefits are more subtle. There is no pattern to who benefits the most.

How difficult is it to use a Swopper for work and hobbies? With only two adjustments, there is a minimal learning curve for using the Swopper. However, because you are sitting on a stool, it can feel significantly firmer than a seat, and so, it can take some time to get used to.

For some people who are used to a backrest, there is a possibility that they may get a little tired after a period of sitting. There are some reports that you can offset this by changing up their position between sitting and standing every 30-40 minutes. Some people will also periodically spend a short period using a reclined backrest so they can completely unload.

What work/hobbies is the Swopper best for? Most people use their Swopper in front of a workstation, and so, it most used for desk-based work, including computer work and writing. Whilst Swopping may feel a little unusual to start, many people report that they get used to the movement in the first few months.

Which is the right Swopper fabric for me? 

This question depends on a few factors and how you prioritise them. In terms of cost, the Swopper in plain artificial leather (previously known as “the Swopper Standard”) is the cheapest option that will still give you the key features of the Swopper chairs. The next option up is the Swopper Classic. This is the same as the Swopper Standard, but you have the option of microfibre fabrics in different colours. For the softest feeling model, we recommend selecting the Gabriel fabric. This also used to be called “the Swopper Air.” Finally, if you really like leather, then you can select the leather fabric option.

Does the seat feel firm? 

If you have previously gotten used to sitting on a gym ball, you might initially find sitting on a Swopper all day to be firm. Firmness can also be a sign that you have been sitting still for a long time, and so, for many people, changing position and keeping active on the Swopper reduces the feeling of firmness. When you are getting used to the stool, it can also feel firm, and so, we recommend building up sitting on the stool slowly (start with 30 minutes and then add 20 minutes every other day).

Is it comfortable to sit without a backrest? 

The answer is it depends. Everyone is slightly different and may require more or less support than others. What is clear is that a number of people prefer sitting without backrest when sitting on a Swopper because the movement is making them gently work their muscles.

Do Swopper stools fit everyone?

The stools have a one-size seat top that fits most adults. The main consideration is the spring strut. The strut comes in 4 sizes, and the choice depends on your height and weight. Please see the options below:

  • Spring strut standard: As the name suggests, this spring strut fits most customers (body weight 50-120 kg).
  • Spring strut high: This fits users from 50-120kg and is best for people who are over 185cm tall.
  • Spring strut low: This fits users from 50-120kg and is best for people whose desk is lower than 65cm.
  • Spring strut light: This fits lighter users from 35-50kg.

Does a Swopper help improve circulation? 

It is surprisingly difficult to record accurate circulatory changes during sitting. As a result, there is a lack of research in this area. What can be said is that if you are encouraging users to gently move whilst Swooping, it would seem likely that you are going to increase blood flow to some degree. What is not known is how beneficial this is.

Does it take time to get used to Swopper sitting?

If you are used to sitting on a standard office chair, there is a high probability that you will need some time to transition to the Swopper stool. To help with this transition, we recommend building your sitting time on the Swopper slowly. We can supply online, seating transition support as part of our aftercare package.
