Abstract: A heart rate monitor system can include a number of electrodes, a heart rate module, and a strap. The number of electrodes are configured to contact a chest of a user and detect electrical signals from a heart of the user. The heart rate module is configured to receive the electrical signals from the number of electrodes and wirelessly transmit heart rate data based on the electrical signals. The strap comprises a non-looping strip of material configured to removably couple to a garment of the user.

Abstract: A chair comprising a chair base, a chair frame mounted to the chair base, a back cushion assembly, and a seat cushion assembly, along with related methods, is described. The chair frame includes an upper and lower frame portion. One or both of the back cushion assembly or the seat cushion assembly can be releasably coupled to the upper frame portion or the lower frame portion, respectively. Such releasable coupling can be achieved via one or more quick-release connectors brought into coupling engagement or disengagement via a rotational, sliding, or push-button movement. In varying examples, the back and seat cushion assemblies each comprise at least one support member and a foam cushion attached thereto. A downward-oriented surface of the seat cushion support member can comprise an integrated tool housing to store a connector actuator tool when not in use.
