We knew the perfect mattress didn’t exist, so we decided to invent it. It took us 70 prototypes and the body data of 10 million sleepers, but we came up with a game-changer: the original Simba Hybrid mattress. This six-layered sleeping beauty offers gravity-defying comfort and innovative solutions to overheating, thanks to our unique titanium alloy Aerocoil® comfort layer and a whole host of other unique Simba features. .
