The Green Tea Cooling Gel Memory Foam Zoned Support Mattress Topper by Zinus will enhance the comfort of your mattress with an extra layer of cooling, conforming, supportive memory foam. The textured zones will reduce pressure at different points of the body for more responsive comfort and a better night's sleep. A cover is not included as our memory foam topper can fit under any standard fitted or deep-pocket fitted sheet. The textured surface of the topper will allow air flow and help to keep your mattress cool and fresh.
