| Comfort | The deepest, plushest mattress we’ve ever made. 31cm deep with 10 individual support layers that have been engineered to give you the greatest ever sleep. Dozens of prototypes led us to this ultimate comfort combination. Like the all Simba Hybrid® Mattresses, it’s medium-firm in feel, however the triple spring system and Bamboo wool layer in the Hybrid® Luxe Mattress provides a plusher and more luxurious feel. Two upper spring layers of 25mm Aerocoils® and a base spring layer of 40mm Aerocoils® deliver unparalleled air circulation, thermal control and pressureless support. | The top AirTech® Comfort foam layer increases the cosiness of the mattress, giving the sleeper a great sleep, night after night. Manufactured in the UK, AirTech® foam is the very latest in memory foam technology, and is 30 times more breathable than some leading foam brands. This, and the memory foam's unique open cell technology, helps to promote air circulation, keeping your mattress fresh and keeps you cool and comfortable throughout the night. |
| Support | The Hybrid has five layers and up to 2,500 springs, whilst the Pro has seven layers, up to 5,000 springs, an additional natural wool top layer and a softer sleep surface. The Luxe has ten layers and up to 6,000 springs, an additional antibacterial wool top layer and our plushest sleep surface ever. Added springs and layers provide a plusher, more luxurious feel, even better heat regulation and ultimately an even more comfy night's sleep. Meaning there's a Simba for a wider range of needs and budgets. | The OTTY Flex utilises our own AirTech® foam - an open cell foam which offers a perfect blend of comfort, breathability and support. The AirTech® Support layer helps to provide a great level of support. This helps to ensure the sleeper wakes up pain and niggle free. The pressure-relieving profiled base has three specially-designed zoning areas, which helps to improve comfortability. |
