I think i have to get a latex mattress, if i want NO motion transfer, so...

i looked at a latex mattress made by Verlo, which felt good (firm core, medium/soft topper), but it's $2000.

Then i thought again about FBM...So inexpensive! Can it be as good as other latex mattresses?

Wondering if a 6" firm core and 2" topper will be good for me? I'm 5'4'', 120lbs, boyfriend is 5'11", 165. He doesn't care what he sleeps on, but i do want it to be supportive enough.

Is there ANY Reason to go with a pre-made mattress (i.e. from Verlo)?

Thank you so much!!
