The perfect mattress didn't exist, so Simba invented it. Experience gravity-defying comfort and a cooler sleep on the only mattress with Simba's unique, patented titanium Aerocoil® spring-comfort layer. You won't need to choose between spring and foam, with the Simba Hybrid, get no-compromise comfort as standard. 2,500 Simba Titanium Aerocoil ® springs: Unlike pure memory foam which traps heat, we've added a layer of patented, super-light springs which act as mini bellows, pushing warm air away. Thousands of our springs absorb pressure in a way traditional mattresses can't, ensuring body weight is evenly distributed. For true gravity-defying comfort. Lay it cool: From cooling Simba-Pure right through to a base that lets hot air escape, our cleverly layered system has been designed for active cooling and maximum airflow. No Motion Transfer: The combination of foam and our cone-shaped springs in our hybrid mattresses, are designed to provide pressure-relieving support and minimise motion transfer between couples, so if one starts rolling the other can soundly sleep on. Good for you, good for the planet: Simba has created a unique industry-first purer foam, Simba-Pure. Simba-Pure is free from chemicals including TCPP, phosphate, parabens, biocides and persistent organic pollutants. These old chemicals are safe for you, but harmful to the planet. 150,000+ Five-Star reviews: Meet the world's most five-star reviewed mattress brand. With 12 industry awards including a Which?
