Zinus is expanding its popular offerings with a new collection of expertly designed spring and hybrid mattresses shipped directly to door. The new designs feature a variety of premium innovations ranging from Adaptive fabric cover to regulate body temperature to best-in-class cradling memory foam layers and supportive individually wrapped steel iCoil® springs. The latest collection, launching and throughout the summer, offers high value, affordably priced mattresses with Queen sizes priced under $400. Now available on Zinus.com, the brand's new Cooling Copper Adaptive™ Memory Foam iCoil® Hybrid Mattress is a blend of spring and memory foam and promotes cooler, cleaner and more comfortable sleep. Starting at $300 for a Queen size mattress, features include: A unique fabric cover with cutting-edge Adaptive™ technology triggers the evaporation of excess moisture as you sleep to prevent overheating and keep you cool throughout the night, and a layer of thermoregulating copper-infused memory foam dispels excess heat. Copper-infused memory foam with natural anti-microbial properties, such as green tea, to neutralize odors. A base layer of individual iCoil® pocket springs to resist motion transfer and provide cradling joint and spine support. High-density edge support foam for reinforced support and comfort.
