i think the more important issue is how u know ur mattress at watever brand is original? sometimes u see mattress promotion that is so good and cheap on popular brand.. u have to wonder... is it fake imitation stuffs?

i'm using Dreamland chiropractic something something.. bought for RM1.2K 4yrs ago.. it was nice and sturdy during the first yr... but the spring getting soft in the last 2 yrs...

and they say good mattress last 10yrs...  so now i doubt actually how real is my dreamland...
