Each and every SkyFloat is shipped automatically with two ceiling plates included. This allows you to conveniently place SkyFloat in the two most commonly used areas in your home. Maybe you prefer, say, one in the kitchen, and one by the couch. But let's just say you absolutely must also use your SkyFloat in the office, as well as in the bedroom. That's why we love its portability! We would then recommend at least two additional ceiling plates. If you're like us, you'll keep finding more and more places to use SkyFloat.
