go try on those mattress yourself. Get the one that you are most comfortable with.

I personally would go for dunlopillo or getha. These are the brand that produce non-spring mattress. I would not buy any mattress with spring. No matter how expensive they are, after some time, the springs will become uneven on parts you sleep often and parts that you don't sleep like the edges. So, you feel some part bulging and some part soften.

I only go for non-spring type of mattress. Dunlopillo have the best and is made of very high quality materials. That's why so expensive. Getha is new player in the market (i think) but still no spring is better for me.

get dunlopillo latex mattresses. These are top quality product that my family has been using for years. My parent used them and now I am also using them. The kingsize mattress i am using now is 10 years old and still in perfect condition. I feel like wanna changing to new mattress just for the sake of getting something new but this old one just refuse to spoil. LOL guess i have to sleep with this thing for the rest of my life which I am perfectly fine with.
