Just want a link to a good value foam for 170lb guy. Don't want to think or research this one.

This mattress from Rocky Mountain has 6" of 100% certified-natural Dunlop latex.
Prices start at $1400.

This 4" PURALUX topper is also 100% natural latex, yet is only $421. Add a 2" topper PURALUX for $233.
Total for 6" is $650.

Why is there such a price difference?
Buying the 2 toppers costs HALF as much as the mattress with the same amount of Latex 6"

Why does the admin keep pushing these vendors that are clearly not a good deal?
I really prefer buying the “raw materials” and adding a $20 mattress cover for a savings of over $800
