How do I assemble the backrest and the seat pan?

The backrest and the seat pan need to be lined up perfectly, and the backrest should be inserted into the end of the groove.
If you failed to insert the screws into one of the sockets, it is most likely that the backrest and the seat pan didn't line up properly.
Please check out the instructions below and try assembling once more.

1. Please disassemble all of the chair parts.
2. Find a flat surface and assemble both armrests on the chair first. You will have the seat + armrests assembled.
3. Place the seat mounted, and insert the backrest inside the seat pan.
* TIP : The armrests will help the chair stay tilted at the right angle.
4. Insert screws from following the numbered spots in the picture.
* TIP : Going diagonal helps easy assembly.
5. Before screwing the bolts, please make sure to press the joints very hard.
* TIP : In case it doesn't work, it is helpful to put up the seat side with a hand and push down the backrest while inserting the bolts.

 


Even if I lock the tilt in the most upright position, it doesn't stop at 90 degrees. Is it defective?

T50's backrest is designed ergonomically, slightly tilted, following the shape of the user's back.

I want to fix the backrest at a certain angle. Do you have any suggestions?

T50's backrest is designed to naturally follow every moment of the user. Thus, the backrest cannot be locked at particular angles.

How can I fix the seat slope at a certain angle?

T50's foward tilting allows you set the seat pan in two positions. If you adjust the seat slope other than these two positions, it won't stay at the angle.

There is a line back of the seat. Is it defective?

The injection gate for molding may form a line in the seat. Please note that these lines do not affect your experience on SIDIZ chairs.

What is the difference between T50 and T80?

The tilting mechanisms are different.
The T80 chair’s patented mechanism (US8528973) is co-designed with ITO design studio Germany and engineered by SIDIZ, which makes it possible for the chair to support your back more closely when you tilt the chair.
Also, T80 is a bit bigger than T50.
