This waterbed still has the feel of a waterbed but with a reduced wave motion. This is due to the tethered support system inside this waterbed. Although you will still feel the water movement, it's more subdued.
Since this water bed has a material inside it, draining it is not as fast or easy as free flow waterbeds. It will take some time to take all the water out and for the material inside it to be completely devoid of water.
It's a good option if you want a more subdued waterbed experience. This mattress contains a layer of resin bonded fiber that is specially engineered to restrict water flow, which keeps the rocking motion to a minimum.
