Nectar Lush Twin X-Long Mattress Only All-Foam
Coolflow - Breathable & Odorless-higher density-provides superior pressure relief-open cell structure= greater recovery
AquaCool-Applied to the center 1/3 of the memory foam=allows the sleeper to stay cool and in a deeper sleep longer.
Energex-retains all of the advantages of visco without the slow recovery-provides a little more "bounce and mobility.".
