To create a chair that takes into account the needs of almost every person, HARAchair conducted 10 years of research. It turned out that the pelvic bones in men and women have different angles (65 degrees for men and 85 degrees for women), and the height and weight of a person play a huge role in the kind of support they require from a chair. While sitting on a chair, the weight of the upper half of the body puts pressure on the pelvis and surrounding tissues, with only 8% of the body’s surface area bearing all that pressure against the seat. Therefore, the pelvis needs effective support.

A sedentary lifestyle is the first and main reason for stagnation of blood in the pelvic organs. In a sitting position, the central blood vessels and arteries are pinched by muscles and cartilage. Like any other fluid, blood always takes the path of least resistance, that is, bypassing the pelvic organs. Blood stasis in the pelvic organs leads to serious illnesses of the genitourinary system (prostatitis, urethritis), rectum (hemorrhoids) and kidneys.

Most seats on the market consist of 2 parts: a back and a seat. HARAchair consists of three parts: a back and two separate seats. The double seat adapts to the weight of the person thanks to the pressure distribution system.

This innovative system has the following advantages:

– Better blood circulation in the perineum is ensured, stagnation of venous blood in the small pelvis is prevented.
– Angular pelvic support reduces pressure on the lumbosacral spine and ligaments.
– The spine is better balanced and acquires the correct S-shape.

– Provides better air circulation in the perineum. (The scrotum temperature for the normal functioning of the testicles should be 3 degrees below body temperature.)
– Prevents damage to the lumbar intervertebral discs.
– The feeling of fatigue caused by a prolonged stay in the chair is reduced.

Performance Benefits

  • The base of a HARAchair is separated in two and designed based on human body science to fit pelvic structure. The HARAchair can be adjusted to give the best comfort to the body.
  • The unique HARAchair mechanism allows easy adjustment of the base of a HARAchair to give comfort. Stable and comfortable posture helps prevent spinal and pelvic disorders as well as hemorrhoids.
  • The base of the HARAchair moves vertically to fit the pelvic structure of a person. The HARAchair  base can adjust itself to fit the ideal pelvic angle for men and women. This relieves the pressure on the spine and pelvis caused by the upper body weight and enables better blood circulation.
  • The HARAchair’s back changes shape to support the entire spine. This can reduce the chance of lower back sag and a hunched posture, which weakens disc walls, stresses back ligaments and causes deterioration of the spine.
  • Thanks to slats in both its back and seat, and the special foam it uses, the HARAchair offers superb breathability. It effectively controls a balance of heat and moisture so users stay comfortable.
  • People don’t fit neatly into three average sizes. Leg and torso lengths can vary independent on a person’s overall height. Adjustable seat depth accommodates different body shapes for long-term comfort.
  • HARAchair’s unique seat design enables people to ease pressure on thighs and widen the angle between legs and torso without feeling like they’re sliding out of their chair. Plus, shorter people gain nearly two inches of seat height.
  • 50 millimeter casters are standard on HARAchairs, so the chairs move easily, an important feature in a time when nearly everyone seems to be in near constant motion.

Whatever you imagined a perfect chair should deliver – productivity, high style, environmental performance – HARAchair has the right answer for you.
