The Serta iComfort Brilliant Luxury Plush Mattress is part of the new iComfort series that replaces the original Serta iComfort Prodigy. The Brilliant 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 Prodigy . The main difference between the prodigy and the brilliant is the brilliant 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.
