Cushioning support for monitoring user activity

A method of monitoring use of a support, comprising:

• providing a support for supporting at least a portion of a user's body, wherein the support comprises a first layer and a second layer opposite the first layer, wherein the first and second layers define a central chamber and a peripheral chamber surrounding the central chamber, wherein the central chamber and the peripheral chamber are filled with a first gas or liquid, wherein the support further comprises a third layer, wherein the third layer is opposite both the first and second layers, wherein the second and third layers define an additional chamber, and wherein the additional chamber is filled with a second gas or liquid which is more viscous than the first gas or liquid;
• sensing a pressure within the support via at least one pressure sensor when the portion of the user's body is positioned upon the support;
• and
• transmitting information relating to the pressure sensed by the at least one pressure sensor to a remote device via an electronics unit in communication with the at least one pressure sensor, wherein the electronics unit and/or remote device is programmed to provide a warning or alert to the user to indicate that their posture is proper or improper when seated.
