Which products use CSS mechanisms?
The CSS series is used in products that need a bed or wide-opening function in addition to seating. Therefore, not only the motion mechanism but also the frame design should be planned around the mechanism.
Product family selection should consider end-user frequency of use, expected bed-mode surface, seating comfort and the manufacturer's assembly speed together.
How is opening ergonomics checked?
The force applied by the user during opening, locking feel, contact between back and seat parts, and risk of upholstery compression should be tested on the prototype.
A technical drawing alone is not enough; sample assembly with real foam, fabric and frame tolerances gives more reliable results before mass production decisions.
Which information should be standardized on the production line?
Hole positions, connection components, left-right part distinction, assembly sequence and control steps should be clear in the production sheet.
In CSS mechanisms, even small alignment differences can affect opening feel, so quality control criteria should be defined for the mechanism before the first series.
