Evaluation of Seat Comfort of Office Armchairs: an Impact of Articulated Seat Support and Gas Spring
This paper describes the application of an alternative seating system. The aim of this alternative approach was to determine the comfort of offi ce armchairs equipped with new construction solutions
The impact of office chair features on lumbar lordosis, intervertebral joint and sacral tilt angles: a radiographic assessment
Seat pan tilt, and to some extent lumbar supports, appear to improve seated postures, however, sitting, regardless of chair features used, still involves near end range flexion of the spine, which will increase stresses to the spine and could be a potential injury generator during prolonged seated exposures.
The effects of the seat cushion contour and the sitting posture on surface pressure distribution and comfort during seated work.
The conclusion was that the cushion contour had a greater effect on seat pan interface pressure parameters than the sitting posture, and AP and MPP can be indicators for assessing seat cushion comfort in a short-term perspective.
Study of the relationships between articular moments, comfort and human posture on a chair
BACKGROUND: One of the aspects that influences the sitting comfort is the distribution of the pressure applied to the skin by the seat surface. In the scientific literature, many studies show
Comfort and pressure distribution in a human contour shaped aircraft seat (developed with 3D scans of the human body).
This study shows that it is possible to design a seat pan and backrest based on the different contours of study subjects using 3D scan technology, but showed that this can only be seen as a first step; additionally biomechanical information and calculations are needed to create ergonomic seats.
Ergonomic aspects in the design of instrumentation for ophthalmic microsurgery
The method suggested in the first project closes a gap in product design as it provides developers with a quantitative, objective and ecologic valid methods for evaluating designs of microsurgical instrumentation.


Study of a Workseat Designed to Preserve Lumbar Lordosis
The researchers concluded that the saddle seat was a viable alternative to the current range of ergonomic chairs as it has none of their inherent problems, but effectively places the user into an ergonomically correct position.

The Design and Evaluation of the Neutral Posture Chair for Surgeons
A neutral posture chair was designed and evaluated to determine if it was a possible means for reducing or eliminating fatigue experienced by surgeons because of seated body posture during
Ergonomic surgeon's chair for use during minimally invasive surgery.
Initial clinical testing of the surgeon's chair could prove the theory that supporting the surgeon with a cockpit type of operating room chair helps to avoid fatigue during long endoscopic procedures.
Developing Seating Designs that Support Traditional Japanese Sitting Postures
The Zafu sitting style is in marked contrast with those in the West, which suggests backrests are not necessary to achieve pelvic tilt in the seated position, and Western chair designs aim to facilitate changes of posture.
Research on pelvic angle variation when using a pelvic support.
In this research, it was found that the change of inclination of the pelvis can be measured continuously using an angle of inclination sensor.
Alterations of the lumbar curve related to posture and seating.

The most important postural factor in the causation of low-back pain in sitting is decrease of the trunk-thigh angle and consequent flattening of the lumbar curve.
Background to sitting at work: research-based requirements for the design of work seats
The body's responses to sitting are complex and involve the anatomy and physiology of the sitter as well as the structure of the seat, the desk and the environment, and how the combination of seat and workplace can reduce the risks of injury by mitigating body loadings over the working day.
An investigation into the immediate effects on comfort, productivity and posture of the Bambach saddle seat and a standard office chair.
While the saddle seat provided reduced levels of lower back discomfort, it demonstrated higher discomfort in the lower limbs, particularly the hips and buttocks, and this has implications for the treatment of low back injury and pain at work, as well as other daily activities that involve prolonged static sitting.
