Martin-G. Steifensand, the son of F. Martin Steifensand, inventor of the first ergonomically designed office chair in the post-war world, has considered these questions for years.

Support the sitting foundation – the pelvis
The pelvis is the lower part of an anatomical trunk, between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton. Sometimes also called bony pelvis or pelvic skeleton.
Think of your back as a building: the pelvis is the concrete foundation, and the rest of the spine represents the vertical floors of the building. You can hold up and position all that vertical weight (of the spine/of the building) in good alignment at the base without pain and for long periods of time.
The lumbar area of the back is above the base of the spine, corresponding to about the 5th floor of the building. Lumbar support, the industry standard for 30+ years, is like pushing on that 5th floor and expecting to support the entire building.
The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones.
The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs and the rectum, while the pelvic floor at the base of the cavity assists in supporting the organs of the abdomen.
In mammals, the bony pelvis has a gap in the middle, significantly larger in females than in males. Their offspring pass through this gap when they are born.
The whole office chair industry has been misleading the world that lumbar support will prevent pain in the lumbar spine and/or hold the spine in neutral!
Elongate the spine – The spine is a column of vertebrae in the back part of the torso (upper body). It is also called the backbone or vertebral column. There is a spinal canal that runs through the length of the spine. Inside this canal is the spinal cord.
Animals that have a spine are called vertebrates, and animals that do not have one are called invertebrates. Humans have a spine, so we are vertebrates. Many vertebrates, including mammals, have intervertebral discs separating the vertebrae.
You’ll notice when your pelvis is supported in a neutral position, your posture will be more upright, taking you away from the surface of the typical back support. This feels fine for a short period, but over time, the postural muscles automatically search for that support.
This leads to tucking the pelvis, resulting in a hunched posture, rounded shoulders, and forward head, which, we know, equals PAIN. Add to that a tall, wide back support, which promotes rounding forward and a forward head posture. Over time, these postures lead to strain and pain. When the pelvis is stable, providing support to the upper back is key to elongating the spine and maintaining an upright posture over time.
Eliminate high-pressure areas—protect the sit bones
What’s the big deal about the seat? We’ve established that the pelvis is the foundation for good support. When the pelvis is held in a neutral posture, the sit bones are positioned directly underneath and are bearing the brunt of downward pressure. This is why supporting the pelvis at the seat surface through materials and contours is critical to alleviating these high pressures and maintaining postural alignment and comfort.
Maintain good posture in resting position
The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, or as a pair the sitting bones, is a large posterior bony protuberance on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet.
A resting position is important in an office chair to take a phone call or just relax during the workday. Typically, recline is used as a resting position by opening the back angle, allowing the individual to lean back.
But the reclined posture causes backward rotation of the pelvis, resulting in that dreaded “C”-shaped spine and forward head posture. Reclining also causes forward migration of the hips on the seat .
