Simba Hybrid Pro King Size Mattress Sleep like a pro with our second generation hybrid mattress. Experience next level comfort and airflow from up to 5,000 titanium Aerocoil® springs and enhanced temperature regulation thanks to the plush natural wool top layer. Supplied rolled in a space-saving box. You’ll receive a straightforward manual to guide you through the set up. The mattress is designed with four handles for ease of movement. More Springs = More Comfort: Unlike pure memory foam which traps heat, we’ve added a layer of 5,000 patented, super-light titanium Aerocoil® 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. 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. Wool layer top layer: Naturally temperature regulating and a dream for hot sleepers. Whatever the season you can rest cool and rest easy. 150,000+ Five-Star reviews: Meet the world’s most five-star reviewed mattress brand. With 12 industry awards including a Which Best Buy 2020 and recommended by T3, Good Housing Institute and Ideal Home, you can rest assured.
