Price Includes:


Genesis 900 DXF Ultra Waveless Waterbed Mattress. The motion rating for our top-of-the-line waterbed mattress is measured to be a 0-second firm and is considered a 100% Ultra waveless mattress.


This sleep system has a firm but a flexible molded sleeping surface that allows both sleepers to lay down into the water, not on a tight taught sleeping surface that can create painful pressure points. Extra vinyl goes through a machining process that puts the surface through a controlled stretch. This extends mattress life, reduces pressure points, and increases overall comfort. Additionally with two sleepers, especially couples where there is a weight difference, this nearly eliminates the ballooning affect that often causes the lighter person to feel like they are sleeping on a bubble. No more displaced water, problem solved!


This is our very best water bed mattress design to fit the wood-sided hard framed waterbed. Innomax builds the Genesis 900 DXF Ultra Waveless Waterbed Mattress as the most luxurious flotation comfort, the most reduced amount of movement, and the maximum amount of support to be found in a liquid support system. It is often described as feeling like you are laying into a wet sponge giving it the nickname “The Sponge Bed” Bad back? If this mattress doesn’t at least offer some level of pain relief, it is probably time to see your physician.


Hardside waterbeds have a durable wood side frame completely surrounding them, this is how you can recognize you have a hardside waterbed. Additionally they have many other replaceable parts to them, one of the most crucial is the mattress you sleep on. The water mattress you are currently viewing  is typically in stock and made to fit old school waterbeds that have the wood frame around them as described. Sizes and measurements are listed below. The waterbed bladder is the heart of any hardside waterbed and the part that you lie down on. It also supports and suspends you throughout the night. Once you have chose your new mattress, do not forget to inspect your safety line. It cannot have holes in it or be broke down along the sides or end.  It is crucial safety net  should you every have a mattress failure. It can contain leakage and prevent water from escaping the bed frame cavity. Additionally while your bed is drained consider replacing the heater as they generally have a life span of 7-8 years. Once you have filled your new mattress, be sure to add the waterbed conditioner to protect vinyl and stop odor. It is at this point you can burp your new mattress to keep it comfy and quiet. Then simply replace your plug and cap and begin to enjoy your new Genesis 900 DXF Ultra Waveless Waterbed Mattress.
