OTTY Flex Memory Mattress Construction 

The OTTY Flex memory foam mattress is developed here in the UK (Yorkshire to be more specific) and uses the latest in foam technologies. The Flex is a 3 layer foam design, utilizing AirTech® foam which is open-cell foam, offering a blend of comfort, breathability and support.

Incorporated in the design is a unique airflow system. Since it is comprised of AirTech® foam, the entire mattress is almost 30 times more breathable than traditional foam mattresses. The airflow system encourages cool airflow and dispenses any excess heat. 

The OTTY Flex memory foam mattress can be placed on any base. Whether that be slatted, adjustable, divan/ box spring or platform/ floor.

If you are accustomed to hybrid mattresses (mattresses using springs and foams) we would highly recommend you head on over to our OTTY mattress review (best awarded) and our OTTY Essential mattress review (budget-friendly) after taking in our opinion on this OTTY Flex mattress review so you can make an informed decision.

OTTY Flex Mattress Cover 

The cover is divided in two by a zip running along the middle of the mattress. This neatly brings the top white section and the lower grey section together. The cover is designed in such a way that it allows the top to be removed and washed with ease. Additionally, the cover pattern also helps with airflow to keep you cool during the hotter nights.

OTTY has included mattress handles as their customer feedback has suggested a need for such. This is always great to see as very few brands offer handles for manoeuvring. It’s also nice to see OTTY reply to their customer's demands.

OTTY Flex Memory Mattress Layers 

1. AirTech® Comfort Layer  

The Visco-elastic properties of memory foam allow for it to contour and mould to the shape of your body. This first comfort layer provides a cosier feel and by using their AirTech® foam this layer provides a blend of comfort, breathability, and support.

2. AirTech® Support Layer

The second layer in the design is the supportive foam layer. Also utilizing the AirTech® foam from OTTY, this layer is designed to support the sleeper and prevent niggles or pain.

3. Profiled Base

Lastly, we have the profiled base layer. This layer has three special-designed zoning areas, targeting comfortability and pressure relief. This layer targets pressure points and adds support to your shoulders and mid-section.

We have included an image to better display the benefits of a base with channelling cut-outs to ensure correct spinal alignment. Research shows that medium to medium-firm mattresses is best for correct spinal alignment and back pain.
