Does anyone know where you can buy a Western-style (i.e. soft) mattress in Kunming?

There is a big 4 storey, upmarket furniture store called ARTSHINE, telephone # 8022591, it's located on the south side of dianshi lu west of the intersection of yang guang xiao qi lu (not sure of the spelling). You can take the 120, 44, or 73 bus. The top floor has western style matresses, duvets, pillows, etc.

Thanks very much!
