Simba Hybrid Double Mattress 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. 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. 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. Lay it cool: From cooling Simba-Pure right through to a base that lets hot air escape. No Motion Transfer: The combination of foam and cone-shaped springs in our hybrid mattresses, are designed to provide pressure-relieving support and minimise motion transfer between couples. Simba Pure: 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 Best Buy 2020 and recommended by T3, Good Housing Institute and Ideal Home, you can rest assured. A sustainable sleep: We want to keep our impact on the planet minimal. We do this by reducing our direct use of energy, materials, logistics and keeping waste super-low. 10 year guarantee: Our mattress is built to last - so we’ve got your back for a decade.
