Need opinion regarding mattress purchase

Hello I want your valued opinion on choosing a mattress for my bed. All these years I have been using a pure cotton mattress. So in our local shops they fill pure cotton inside a cloth and sew it to make a mattress. Now I am in Bengaluru where I need to buy a mattress. On the internet when I search I see mostly Wajefit's Shapesense Orthopedic Classic memory foam. https://dl.flipkart.com/s/HqJOo3uuuN these types of bed which I have never used.

So is there someone who can share if I should try to get a cotton handmade bed or these Wakefit ones. How was your experience in this regard
