A mattress device provides a high information variety from a low number of sensors configured and placed in correspondence with a mattress core layer and a mattress top layer of the mattress device in order to monitor a patient's sleep behavior. Mattress core and top layers provide a static position transmission characteristic and a dynamic impulse transmission characteristic enabling the sensors to recognize body imprint position and body impulses induced by the sleeping patient with a broad bandwidth. In an alternate embodiment, the mattress device may be combined with a signal coder capable of receiving signals or signal components from the sensors and transform them in an analog signal that can be received and processed by a conventional sound card of a computer. A decoding program installed on the computer decodes the alphanumeric information processed from the analog signal by the sound card and makes it available for further interpretation.
