Initial operators typically configured their A380s for three-class service, while adding extra features for passengers in premium cabins. Launch customer Singapore Airlines introduced partly enclosed first class suites on its A380s in 2007, each featuring a leather seat with a separate bed; center suites could be joined to create a double bed. A year later, Qantas debuted a new first class seat-bed and a sofa lounge at the front of the upper deck on its A380s, and in 2009 Air France unveiled an upper deck electronic art gallery. In late 2008, Emirates introduced "shower spas" in first class on its A380s allowing each first class passenger five minutes of hot water, drawing on 2.5 tonnes of water although only 60% of it was used.
