| Layers | Memory Foam, Reflex Foam. | AirTech® Comfort Layer, Unique Airflow System (Open Cell Foam), AirTech® Support Layer, Profiled Base Foam (3 Zones). |
| Cover | A washable CoolMax mattress cover (at 40°C).

We recommend washing the cover once a month at 40 degrees to get the best sleeping experience. |

| Comfort | The top layer of memory foam moulds to the contours of your body providing 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. |
| Support | This 3cm memory foam top layer also provides pressure-relief. | 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. |
