Selene, representing the Titan Goddess of the Moon, is a mattress that will help you feel like your sleeping under the simple moonlight. This mattress consists of a very firm innerspring support base and a single 2" Extra Soft Topper. You can sleep on the innerspring side for a firm supportive sleep or sleep on the 2" Extra Soft Topper side to have a softer but still supportive sleep. This is perfect for those on a budget who want a pure mattress but still want to sleep comfortable. The Selene is also good for those who want to try out rubber, but are still a little nervous of the idea as you always have the choice of turning the bed over to the innerspring side if you do not like the extra soft rubber topper.
