Research methode: The type of this research is survey approach with Cross Sectional Study. Sampling using purposive simple sampling technique. The number of samples meeting the inclusion criteria was 81 people. Intake of anthropometry measurement data of body dimension and dimension of chair using medline. Measurement of vertebral alignment using flexicurve. The obtained data were tested by chi square test through the crosstabulation Result of research: The result of crossing between seat ergonomics and vertebral alignment shows a p value of 0.01. Since p < 0.05 then H0 is rejected, which means there is a relationship between ergonomic chair with alignment vertebra Conclusion: There is a relationship between chair ergonomics and alignment vertebra in students class XII.
