The Serta iComfort Visionary EFX Cushion Firm Mattress is part of the new iComfort series that is a new model complimenting the old savant model offering an additional medium firm to plush firm feel to the original Serta iComfort Savant Plush.  The Visionary has a new wick away cover and a small additional percentage of gel in the memory foam.  One of our customers asked if we have anything similar and we have almost the exact same mattress in the updated iComfort Savant Cushion Firm . The main difference between the Savant and the Visionary is the Visionary will have a very slight amount more of gel inside the memory foam and the brilliant has a wick away cover and the prodigy has a cotton poly blend. The coolness factor is insignificant in our opinion on the cover and considering that most people put a mattress protector on their mattress it will negate any difference in coolness the cover would of provided.
