Ah this is a great idea! I have ordered from foam by mail before. Is it illegal to just stack everything without a encasement? Reason I ask, I recently got a super stretchy bottom sheet and it REALLY allows that memory foam to offer the sink in feeling. I love it. I feel anything between the foam and my body (water proof cover, standard bottom sheet, etc) discounts the overall feeling of the foam.

This is the topper I am using. Typical copy/paste low density memory foam. Ultra plush, only lasts ~1 year or so before it begins to tear: https://www.amazon.com/gp/product/B0792L9WLN

Thanks for explaining that firmness does not = longevity.
