I bought a latex foam mattress several years back, and it's been wonderful. Has the isolation and "cush" of memory foam (i.e. Tempurpedic) without the heat. You still feel like you're sleeping on the mattress, as opposed to the sensation of a memory foam mattress where you feel like you're sleeping in the mattress.
Downsides? Cost. And weight/ease of moving.
