Firmness Info

The Simba Hybrid Pro is medium-firm in feel, however, because of the dual spring layers and wool layer the Pro provides a slightly softer, plusher, more luxurious feel than the Hybrid. 95% of Simba sleepers love their mattress. If it doesn't work for you, Simba mattresses that are returned are either refurbished or recycled; they never go near a landfill site.

Comfort
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.
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 now a Simba for a wider range of needs and budgets. An even thicker knitted cover increases the comfort without compromising airflow. Wool is naturally temperature regulating and moisture wicking and a dream for hot sleepers. Whatever the season you can rest cool and rest easy. Open cell Simbatex foam is infused with graphite for enhanced cooling. The conical design of the springs means they are cone-shaped and allow for greater airflow between the springs.
Support
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.
More miQro® springs mean greater airflow and better body weight distribution. Plush, lush, gravity-defying comfort. Up to 2,500 additional miQro® springs mean greater airflow and better body weight distribution. These 25mm conical pocket miQro springs are made with 100% British steel, manufactured in Leeds and are enclosed in a 100% polyester pocket. High definition foam with edge support means you won't get that feeling of rolling or falling off the bed when sleeping or sitting on the border. A zoned support base provides different levels of support to different areas of your body to reduce pressure points.
