The mattress is available in six different sizes – Single, Double, Euro Double, King, Euro King, and Super King. All products are available for a free, 30-night trial and come with free delivery and return policy.

Commercially launched into the UK domestic market in 2006, Ergoflex boasts over 13 years of mattress manufacturing and selling experience. The brand pioneered a number of build variations and solutions for mattresses, including affordability in the memory foam mattresses sector, compression packing, vacuum-sealing, and mattress boxing. In June 2019, Ergoflex 5G was acknowledged as one of the top ten mattresses in the UK by “Which?” – The UK’s leading consumer advice portal.

Ergoflex 5G consists of four layers. Here are the details for each:

Protective Inner Cover

The inner cover rests just below the outer cover and protects the main layers of the mattress from physical damage, dust mites and insects.

HD Visco-elastic 5G Memory Foam

The 9cm thick, high-density Visco-elastic memory foam provides excellent support and pressure point relief. The ergonomic design and orthopaedic elements work together to relieve pressure while also dispersing the heat. The spherical-shaped open cells design allows for contouring to the sleepers’ body shape and eliminate motion transfer, making it an excellent choice for couples.

Cool-sleep Airflow System

Ergoflex 5G was specifically designed to grant excellent temperature regulation. The main cooling system is positioned exactly in the middle and is represented by a 5cm cool-sleep airflow layer. Its egg carton shape allows for increased airflow and heat dispersion, further enhanced by the Visco-elastic memory foam above. The secret lies in the new generation of memory foams that disperse the heat much more effectively compared to older versions. Finally, the cooling process is boosted by the design of the TENCEL cover, which features 3D mesh panels that prevent heat retention.

High Resilience Impact-resistant Foundation

The foundation base is 9cm thick and primarily serves as weighted support for all upper layers and enhances longevity. It is also responsible for distributing support evenly across the whole mattress surface, ensuring that sleepers will feel the same regardless of their preferred sleeping positions.

Mattress Cover

Every Ergoflex 5G mattress arrives encased in a tailored TENCEL cover. TENCEL is a botanical material, which is entirely natural and sustainable. It’s most robust properties are moisture-wicking and breathability that is on-par with (and even higher than) natural cotton. This enhances the cooling system of the mattress and keeps sleepers dry even during the hottest summer days. Moreover, thanks to its cellular fibre construction design, it has natural anti-bacterial properties

The cover is very sturdy and durable while being silky and soft to the touch. The cover is removable and washable and should be machine-washed at 30°.

Firmness, Feel & Support

Lying down on the mattress feels soft and cosy, although the firmness levels may be considered too high for some customers. Generally, orthopaedic mattresses need to be firmer to offer pressure point relief, and Ergoflex 5G is no exception. Sleepers under 30-35 years may find it too firm for their liking.

The product offers exceptional motion cancellation thanks to its design and memory foam properties, making it an ideal choice for couples. Furthermore, the sinkage and responsiveness of the mattress are rather good compared to other mattresses, which will positively affect sex life. The mattress cover feels very soft and cool, yet is highly durable and sturdy. It is made of natural and hypoallergenic materials. Finally, Ergoflex has high indentation load deflection rating (ILD), which is used to measure the sinkage of the mattress and is CertiPur-US & OKEO-TEX 100 certified.

Purchase & Delivery Process

The process is extremely straightforward. Customers need to pick their desired size and firmness level before the checkout, and either pay with a card or apply for a 0% financing. All the information is conveniently laid out on the pricing page of the brand’s website. Each mattress features free delivery and returns, and a free, 30-night free trial.

Customer support

When it comes to customer support, Ergoflex is on top of its game. While it doesn’t offer 24/7 customer support, the staff is very knowledgeable, friendly and responsive, and ready to assist customers with any queries.

  • Phone Support
    The brand can be reached via a dedicated hotline, Monday to Friday from 09:00 to 17:00.

  • FAQ
    The comprehensive FAQ section provides answers to just about any question a customer may have.
  • Blog
    The blog is updated extremely inconsistently and features topics like best sleeping positions, sleeping environment, food, sleep facts, etc.

Final Word

Overall, Ergoflex 5G is an excellent choice in the memory foam mattresses category. The unique temperature control design paired with consistent support over the entire mattress surface, pressure point relief, ten years warranty and low price point is more than enough to earn five stars rating in any customer’s book. The few cons like the short trial period and the absence of a soft mattress option can be bothersome, but shouldn’t make or break the final decision.
