Project with Handong University's Capstone Team 

On May 26, 2023, NOOGI presented with the Capstone team of Handong University under the theme of "Comparative Study on Chair Usage on

Correct Sitting Positions" at the Spring Conference

of the ESK (Ergonomics Society of Korea). 

Through this conference, 

NOOGI certified magnificent technical 

differences in medical and ergonomically.

A study compared the structural characteristics

of NOOGI's Tritzoi Light chair and two chairs which are from different companies (Domestic brand 'I', global brand 'K').

Analyzed an ergonomic structural feature and correlation of accurate posture and planned to announce detailed data in an upcoming conference.

The experimentation of 30 people on muscle tension and body pressure dispersion verified that the NOOGI chair requires less strength on muscle than other companies' products and body pressure dispersion is evenly achieved when sitting in the correct position.

In December, NOOGI will publish a paper with an updated result for overseas ergonomic journals at the Fall Conference.

In addition, the durability experiment of Tritzoi was held by KTL (Korean Testing Lab) and verified seat frames divided into four sections are ergonomically functional.

Two types of tests were conducted and one was forced to repeatedly move 20,000 times each of the NOOGI's special springs backward and forward with 75 kg weighing.

The other was, a load test of 85kg, 100kg, and 150kg was conducted for 1 minute to prove the product stability of proper body pressure dispersion.

*Lower appearance of low hertz frequencies and 

the higher appearance of intermediate hertz frequencies 

(40 - 60 Hz), lower rate of muscle fatigue.

Last September, experimented with 20 college students sitting down for more than one hour in two different chairs to analyze the difference in muscle fatigue rate. 

As a result, domestic manufactured products give over 55% higher muscle fatigue compared to NOOGI’s chair.
