The iDream™ Gel Memory Foam Collection has been designed using our advanced Gel technology that wicks away heat to maintain balanced body temperature. Combining the benefits of gel with our ventilated, open-cell design, iDream gel memory foam is 12 times more breathable than other nationally advertised memory foam products. It is also more supportive, as millions of Gel beads gather in areas that need it most for additional support and personalized pressure relief, creating cooler, better, more supportive sleep. iDream mattresses are made using high density eco-flex foam that is Certipur Certified for no harmful chemicals. The superior durability of this high quality design is backed by our industry leading 25 Year Warranty.
