A queen size water bed is 60 x 84", a little longer than a regular queen size bed, and a little narrower. The purchased queen waterbed sheets are 2 twin bed sheets sewn together at the bottom with added triangles at each corner to hold the bottom sheets down. So, the purchased sheets are not wide enough for 2 people in 1 queen sized waterbed. I always adapted regular sheets - twin flat on the bottom and queen size on top. A normal queen size quilt will work, or you might want to make it a little longer.
