Swimming in info - please help. ECO-mattress hunting...or not?

Just looking for name suggestions.

Fairly small stomach/back/side sleeper looking for Eco-Friendly mattress with memory foam feel. We believe we prefer firm, easy move-ability while sleeping and not too hot.

Midline budget 1400-2200 for a king and foundation

Hoping to avoid Sealy, Simmons, Tempurpedic and the other big shots to get the best value as suggested on here (and support smaller business, thats always refreshing).

Opinions on SAvvy, Magniflex, Vita-Talalay, Pure Bliss, Tempur?

We live in Philadelphia.
