Many jobs require workers to be on their knees to effectively undertake tasks close to the ground. Plumbers, electricians and welders for example, are likely to work in a kneeling position with limited space for movement of the trunk and upper limbs. Most of these workers use knee protectors to reduce discomfort, however these protectors can be uncomfortable and do not necessarily reduce the risk of musculoskeletal injury associated with inappropriate posture of the back and upper limbs. These risks can be averted with the use of the proper ergonomic chair.
This article presents the benefits associated with the use of ergonomic chairs especially designed for work on the floor.
Being on one’s knees is not a natural position per say for us humans. In effect, the anatomy of the knee is not suited to resist long periods in this position. Workers who must be on their knees frequently complain of discomfort. In the long-run, this posture can lead to more serious musculoskeletal disorders; a direct result of repetitive pressure placed on the knees. Moreover, this restrictive posture is often held on uneven surfaces sometimes humid or covered in certain types of products or particles.
Over time, redness, calluses and eventually, knee bursitis may appear. Bursitis is the inflammation of the fluid-filled sacs (bursae) that reduce friction and cushions pressure points between your bones and the tendons and muscles near your joints during movement of the knees. Frequent kneeling also hampers proper blood circulation in the lower limbs which leads to serious discomfort.

Why use an ergonomic chair for work on the floor?
There are many types of chairs designed specifically for work in difficult postures such as kneeling. These three models are among them; they allow workers to adapt their posture according to the task required.
1- Flex
This ergonomic chair allows the user to sit on the ground with adequate back support. The backrest tilts to adjust to any movement. The Flex promotes proper blood circulation in the lower limbs and ensures the user maintains a straight back. The backrest may also be used as a seat for work on higher surfaces. This position limits any strain placed on the knees and back when working close to the ground.
2- Flex2
This chair allows the same positioning as the Flex with some added benefits. First, the backrest is larger in order to provide optimal cervical to lumbar support and may be tilted in varying degrees to adapt to multiple tasks close to the floor. In addition, the Flex 2 is equipped with armrests; an essential element to reduce upper limb fatigue.
3- Stag4
The Stag4 is another option that allows work to be done close to the ground or higher. In fact, 3 different positions make it possible to work comfortably when positioned a couple of centimeters from the ground and all the way up to five feet high.
– The knees are placed on padded rests and the worker is supported by the chest rest. This posture allows work to be undertaken close to the floor while ensuring proper placement of the knees and lower limbs as well as providing optimal alignment of the spine.
– With knees resting on the support provided for this purpose, the worker sits on the angled seat. This position allows the user to accomplish tasks higher while maintaining the natural curve of the spine and decreasing the feeling of pressure on the knee joints.
– For work undertaken four or five feet from the ground, it is possible to use the seat as a stool. This position prevents bending of the trunk and knees for optimal comfort.
Evaluating needs
Before purchasing any equipment, it is important to analyze the specific requirements of any task to ensure the product can meet them. You can also try the different ergonomic chairs available to ensure efficiency within your work environment.
Ergonomic chairs designed for work close to the floor may seem expensive compared to the other options available. However, these chairs not only provide comfort but more importantly, they reduce the risk of injury. This equipment must be seen as an investment into one’s short and long term physical well-being.
