Ergonomic Feature 

You will find minimum differences between SIDIZ T50 and SIDIZ T80. For instance, in the SIDIZ T50 design, a bit of change of the armrests and the lumbar support makes it less comfortable.

The headrest of the SIDIZ T50 feels a bit flimsy and lacks proper support. Nonetheless, it is a curved headrest that is attached to the backrest. 

I feel the headrest of SIDIZ T80 more comfortably resting on my head, which holds the neck in a perfect position. The best part is that the headrest does not move with the pressure, which would have been pretty disturbing. 

Both have adjustable armrests that can be changed in height width and can be pivoted to bring them inward and outward. The bad side of the SIDIZ T80 armrests is that the lumbar support moves along with it when you change the height. 

The Mesh Backrest of the SIDIZ T80 is much smoother and more durable than that of the SIDIZ T50. As a result, the SIDIZ T80 is more comfortable and breathable at the same time.

Both the SIDIZ T50 and SIDIZ T80 come with great tilting angles, and the adjustments are made in the same manner. However, the SIDIZ T50 has 5 tilt lock positions, whereas the SIDIZ T80 has a maximum of 4 different lock positions. 

The lumbar support of both the chairs are perfectly curved and contour the body. However, the lumbar support of the SIDIZ T80 has a hard frame, and the lumbar depth adjustments are missing.
