I use this one with the vibrating shaker inserted into my pillowcase. It'll raise the dead: https://www.sonicalert.com/SBB500SS-Alarm-Clock

A year ago or so I was at a fire seminar. I mentioned to the woman who was presenting this seminar that at night I was almost totally deaf when I was in bed without my hearing aids. She immediately presented me with her business card and asked me to call or email her. I did the next day. The fire department came out and installed an alarm clock that connects to the smoke detector in my bedroom but also had a disc that goes under my bottom fitted sheet. When the alarm is set and goes off my bed vibrates. Trust me....it works! This was at no cost to me. I don't even notice the disc under the sheet and only if my arm is under the pillow.
