Zigbee Weight or Pressure Sensor?

Hey all. I’d like my smart home to know if I’m sitting on my couch, or sleeping in my bed. I’m guessing one way to do this would be some sort of a pressure/weight sensor that could tell if more than X pounds was pressing down on my couch or bed, and that sensor would probably be slipped under the mattress/cushions.

Anyone done this?

I bet aliexpress has devices like that.

I use an aqara leak sensor set to occupancy mode with a pressure mat wires installed on the screws that are used for leak detection for my bed sensor at the moment.
