The investigators propose a cross-sectional study of adult participants recruited from the community. Enrolled participants will have four sets of three automated blood pressure measurements, with each set taken with the arm positioned and supported as follows:
* Arm supported on a desk, with mid-cuff at mid-heart level (4th intercostal space)
* Desk1
* Reference measurement
* Arm supported on the participant's lap
* Lap
* Arm hanging at the participant's side, unsupported
* Side
* The last period of triplicate BP measurements will always have the arm supported and mid-cuff positioned at mid-heart level
* Desk2
In the prior 3 periods, the arm position and support conditions are randomly ordered. Each participant will undergo a total of 12 systolic and 12 diastolic BP measurements
