It's called a Murphy Bed.



In the next photo you can see a hinged joint on the L shaped base of the table that folds and lowers as the bed is revealed.



In the video below, the dining/queen bed combo is at the 1.30 mark.

Hafele also has Murphy kits for a Queen size but they don't seem to be available for the Malaysian market. They do have the Tavoletto which converts a single bed to a desk. You should still head to the showroom to discuss hardware options and mechanisms just so you have a better understanding in person (and maybe check on the availability of a Queen kit). They also have a sale coming up.



EDIT: Resource Furniture ships to port as well so if you're interested, drop them an email.
