Showing devotion to comfort with their consecutive iterations on their product, this is Ergoflex’s 5th generation of their popular all-foam mattress.
Focusing on quality foams for less this mattress has a unique composition of three foam layers.
For those prone to allergies this mattress is perfect as it is both asthma and allergy friendly also, as well as being anti-microbial.
The Ergoflex 5G is CertiPur-US and OEKO-Tex 100 certified and manufactured to UK safety standards.
Outlined below are the three layers which make up the Ergoflex 5G mattress.
1. Comfort Layer
The top layer is constructed using 3.5 inches of true high-density ACPT memory foam.
Which is an open cell visco-elastic memory foam with orthopaedic pressure-reducing properties, offering great health benefits and is used in hospitals throughout Europe.
The material is great for body contouring providing a weightless feeling in hugging the body and relieving pressure point pain in all sleeping positions.
This layer also helps dissipate motion transfer meaning no nightly disturbances for you or your partner.
2. Transitional Layer
Below the comfort layer you will find 2 inches of Cool-Sleep Airflow foam, designed in an egg crate shape which allows hot air to escape from the surface layer during sleep.
Allowing for fantastic airflow throughout the mattress giving the user a sleep cool feel.
This material also cradles the body giving you a snug and secure feeling throughout the night.
3. Base Layer 
The base layer is made up of 3.5 inches of protective high-resilience base foam which gives the mattress a supportive and sturdy foundation, while also increasing the longevity of the mattress.
This high-resilience foam also ensures optimal spinal alignment, allowing more of your back to hit the surface of the mattress, which health experts state is good for relieving pressure on shoulders and hips also.   
Mattress cover 
The Ergoflex 5G mattress cover is made of TENCEL fabric a type of semi-synthetic rayon combined with the spun wood cellulose lyocell.
This entirely natural and sustainable fabric naturally wicks away moisture from the body allowing for a sleep cool feel and its breathability outperforms traditional cotton.
The cover has a luxuriously silky soft touch yet is exceptionally strong and durable, the cover also includes 3D mesh panels allowing for better airflow. 
For all spillages, spot cleaning is advised, but the mattress is washable as outlined by the manufacturer.

Firmness, Feel & Support

The Ergoflex 5G mattress measures a 6.5 out of 10 on the firmness scales, a medium firm mattress.
This range of firmness is recommended by back doctors especially with the contouring aspect on the top layer and the bottom two layers supporting the spine so well.
Making the mattress best for those who sleep on their side or back.
Due to these elements of contouring and spinal support the mattress is excellent for back pain relief.
As the mattress conforms closely to the body it also alleviates a significant amount of pain in hips and shoulders.
The mattress provides good edge support meaning if you sit or lie on the side of the bed you should not feel any sinkage.
Motion transfer is practically non-existent with the Ergoflex 5G mattress   leading to less disturbances for combination sleepers.
Given the high-quality materials used in the production of the mattress most users find the Ergoflex 5G extremely comfortable and when lying on the mattress it gives a weightless feel while remaining supportive and sturdy, so no real sinkage is felt.
As sinkage is limited, the mattress maintains a healthy spinal alignment in all body positions.
