Engineering review
Match the model to the chair, not only to the catalog.
For export chair programs, Samiktech checks the gas lift around dimensions, force curve, actuation compatibility, marking and packing requirements. If the buyer has an existing supplier code, sample or drawing, we can translate it into a clear SMT quotation model.

Drawing interpretation
Dimensions buyers should mark before sending a drawing.
Nominal stroke
The vertical travel expected by the buyer. This is usually the first sizing parameter.
Rated force
Extension force in Newtons. Force should match seat weight, mechanism and user feeling.
Interface size
Seat mechanism and cone/taper connection dimensions. Small mismatch can affect assembly.
