I saw some premium quality leather sofa at STAR living Quill City Mall. U wont feel hot even if u sit for a long period of time~

I heard from the salesman the reason why u won't feel hot even if u sit for a long period of time is that they are using goose feathers especially for those premium quality sofa~ My mum & I tested the sofa b4 at the showroom & it's true..considering the aircon at that time is not really cool
