Rightly said and totally agreed with @Baleno1300
I myself am using Molty Ortho since last year, and fully satisfied with it. I bought following one (in King Size) and ordered online on the official website (best option in my view, included 1000 Rs. delivery charges from Lahore to Islamabad):

I would sincerely suggest Molty Foam Brand (instead of Diamond, etc.), then Foam Mattress (instead of Spring), and those who have backache; Molty Ortho Mattress (instead of any spring Mattress, or Ortho cool gel, etc.).
