I've tried it, its a pocket coil system, with a outside frame that when you sit on it, it doesnt sag after awhile. I believe it has a rather high # pocket coil count 350+ or something. Its quite nice.

Depends on if you like firm or plush, their plush ones are nice, firm is quite good for the back. I find that they are damned expensive in Malaysia, about 10-20k for a king or 8-12k for a queen. Sometimes @ robinson you can get them for half off with an additional 1000 or 2000 back.

I can't remember very well, but I think the Shangri La is using the Simmons, if its not simmons its Sealy. But overall its quite nice. Although I've never been able to do the thing like the commercial where you put a cup of wine and jump on the other side. Everytime I even put a cup with some rocks inside it always falls over.
