Abstract: Various technologies described herein pertain to sensing cardiovascular risk factors of a user. A chair includes one or more sensors configured to output signals indicative of conditions at site(s) on a body of a user. A seat of the chair, a back of the chair, and/or arms of the chair can include the sensor(s). Moreover, the chair includes a collection circuit configured to receive the signals from the sensor(s). A risk factor evaluation component is configured to detect a pulse wave velocity of the user based on the signals from the sensor(s). The risk factor evaluation component is further configured to perform a pulse wave analysis of the user based on a morphology of a pulse pressure waveform of the user, and the pulse pressure waveform is detected based on the signals from the sensor(s).
