PROBLEM TO BE SOLVED: To provide a bed apparatus having a simple structure, allowing a user thereon to listen to music with presence regardless of a listening position, allowing the user thereon to listen to music even with a reduced signal level, and allowing the user thereon to listen to music in a relaxed state even when another user thereon sleeps. SOLUTION: The bed apparatus includes a bed body, an audio signal amplification portion for amplifying audio signals, operation portions for increasing and decreasing amplification degree of the audio signals amplified by the audio signal amplification portion, rails fixed substantially parallel to one side surface of the bed body, and speakers slidably held on the rails for outputting the audio signals amplified by the audio signal amplification portion as music.
