There’s a company online called Afloat Waterbeds. Has anyone done business with them? The only thing that sounds off about them is that they say they are affiliated with City Furniture (they give a City Furniture address as there mailing address) and I contacted City Furniture and they said they’re not affiliated with Afloat.
I’m unfamiliar with them, but their website seems legitimate at the very least. I’m mostly commenting in the hopes that someone recognizes the name and chimes in here for you.
