Ergoflex Mattress Review


Written by Kyle

Last Updated: 12th April, 2022

Ergoflex is a unique brand as they claim to be the first to bring out an affordably-priced memory foam mattress, the first to provide a one-size-fits-all mattress and the first to offer all of this in an online-only business model. The idea Ergoflex envisioned over a decade ago has now paved the way and become the industry norm here in the United Kingdom.

Please keep reading for all the useful information regarding the Ergoflex mattress, the only mattress-in-a-box brand that has been trading longer than its 10-year warranty period.

Mattress Performance Test

1. Pressure Relief

ergoflex pressure relief

Due to the memory foam construction, the Ergoflex mattress offers excellent pressure relief while providing support. For this reason, tests show that the mattress can be suited for multiple sleeping positions while providing comfort and pressure distribution.

• Side Sleepers➮ Pressure is well distributed with body contouring abilities, particularly in the shoulders and hips.
• Back Sleepers➮ The mattress provides comfort and pressure relief in all body areas, including under the head.
• Front/ Stomach Sleepers➮ Front sleepers should find the mattress comfortable, supportive and pressure relieving. There isn't much sinkage in the stomach and hip areas; however, this can depend on the weight and personal preference.

2. Temperature Regulation

temperature control

Heat retention is something to bear in mind with any memory foam mattress. Memory foam is notorious for generating overheating during the night.

The Ergoflex maintains very little heat in contrast to comparable foam mattresses, yet some heat appears to remain, particularly around the mattress's edges. However, unless you are a hot sleeper, you need not be too concerned because most of the heat evaporates rapidly.

3. Spinal Alignment

spinal alignment test ergoflex

It is critical to ensure that your spine is appropriately positioned in order to avoid future back issues.

This mattress' top memory foam layer performs a great job of maintaining the sleeper's spine structure by allowing the hips and shoulders to sink somewhat deeper into the mattress, keeping the sleeper's spine straight.

4. Motion Isolation

Memory foam mattresses are a popular choice for those seeking motion isolation, as they are often more effective than mattresses with a hybrid or pocket sprung construction.

The excellent motion isolation could be due to the all-foam construction and thick memory foam layers. This could be a good option for couples or restless sleepers who find themselves disturbed easily by movement.

5. Edge Support

Our tests found the Ergoflex mattress lacked sufficient edge support, which could result in the edges sagging over time. This increased sinking around the sides could also shorten the mattress's lifespan.

Due to the lack of edge support, this mattress may not be suitable for those who prefer to use the entirety of the mattress surface. However, it's worth noting that the inner parts of the mattress are supportive, despite minor sinking.

6. Mattress Firmness

It's important to note that firmness is largely subjective; however, we gave the mattress a medium firmness, going slightly towards the softer side. This is due to the thick, slow response memory foam, which offers comfort and pressure relief.

That being said, firmness levels can differ depending on weight, sleeping position and personal preferences. For example, a heavier person may find this mattress softer due to the increased pressure, whereas it might feel firmer for a lightweight person due to lack of sinkage.

Due to the firmness and feel, Ergoflex claims that this 5G mattress is Ideal for sufferers of back pain, fibromyalgia, circulation problems or joint complaints.

Ergoflex Mattress Construction 

The Scandanavian orthopaedic designed 5th Generation from Ergoflex (aka Ergoflex 5G) has a unique composition of 3 foam layers. The mattress is perfect for those prone to allergies as it is asthma and allergy-friendly, as well as anti-microbial, which means it inhibits the growth of microorganisms and pathogenic microorganisms.

The Ergoflex is CertiPur-US® & OKEO-TEX® 100 certified. It is manufactured to BS 5852 and BS 7177 UK Safety Standards.

Ergoflex Foam Layers 

ergoflex layers
  1. Visco-Elastic Memory Foam Layer - The top layer is made from High-Density ACPT™ memory foam. This memory foam is designed with billions of spherical shaped open cells with orthopaedic pressure-reducing properties. HD memory foam has great health benefits and is even used in hospitals throughout Europe. Memory foam is widely known as the material to dissipate motion transfer. This means zero partner disturbance, making it a suitable option for couples.
  2. Cool-Sleep™ Airflow Layer - This is the layer responsible for the optimal sleeping climate. The dome-shaped layer is great for airflow and is also perfect for conforming to the shape of your body, giving you that snug and secure feeling.
  3. High-Resilience Base Foam - A great mattress is always backed up by a supportive base; this not only provides pushback but also increases the longevity of the mattress. This high-resilience foam also ensures optimal spinal alignment in any position.

Ergoflex 5G Cover 

The cover is split into two parts, the inner and outer. The outer cover is made from TENCEL®, which is entirely sustainable and natural, with moisture-wicking and breathability abilities. The cover is strong and durable yet luxuriously silky and soft to the touch. A great feature about the Ergoflex cover is that it includes 3D mesh panels to allow for better airflow on each end.

The TENCEL cellular fibre construction is naturally anti-bacterial and therefore achieves good hygienic performance. The cover is also practical if you manage to get it dirty as you can remove it and wash up to 30°C.

The Ergoflex also engineered the 5th generation with an inner protective cover. This microfine layer encases the mattress core and keeps the mattress all snug.

How Thick Is the Ergoflex Mattress?

The Ergoflex is about the industry average in terms of thickness. It is 23cm in-depth, so rest assured your bedsheets will also be compatible with the Ergoflex. The mattress can also hold up to 18 stone / 114 kg per person per side (based on two people per bed).
