This is a top of the line magnetic mattress made by Lyon Legacy. It originally cost $750. The magnets are powerful and I now have a pacemaker so cannot use it. Someone with a massage studio could charge $15. for 30 minutes or an hour for a client to use it...or you can sleep on it all night and feel great in the AM. There are many health benefits.
