I've bought the single version. It is set up and inflate quickly, with the electric pump that goes within 3 to 5 minutes. I've slept on royal (3 nights) got, did not even notice that I'm sleeping on an air bed. A smidgen of air went out, but it was comfortable and if you would have value placed on it would have again can re-inflation after 2 nights. Am delighted with the quality. Let out air was thanks to the electric pump, which is already installed, super easy and, above all, completely, so that you can then easily fold it. Can the product good conscience.
