A free flow hardside waterbed mattress does not contain any wave reducing material, so you will experience the full motion that the waterbed mattress has to offer. If you love the traditional 'old time' type waterbed mattresses, then this is the bed for you.
Get the best feel and performance from your free flow waterbed when you fill it to just below the top of your vinyl safety liner (sold separately). Enjoy the feel and benefits of weightless, pressure free support. Your body is comprised of 90% water, so why not support it the way nature intended in a gravity neutral, fluid environment. For use in a traditional hard-side wood frame.
