I visited the SATS Premier Lounge at Terminal 2 which is located in the Departure Transit Hall on Level 3. As I had a morning flight to catch, I arrived at the lounge around 645am and it was almost empty. For those on a longer layover, there's ample reading materials in the lounge - magazines, newspapers and even the computers if you're travelling (extremely) light. Overall a pretty decent lounge with a comfortable environment and the right facilities. It was not extremely fancy but definitely had everything you required for a lengthy layover in Singapore.
