Dormeo has many models, but none as cooling and breathable as the Fresh Deluxe.

Equipped with the company’s next-gen foam, Ecocell, this bed provides unmatched comfort while retaining ventilation and breathability. Plus, thanks to the foam’s three-dimensional cellular structure, the Dormeo Fresh Deluxe lets air travel throughout the mattress, cooling and supporting the sleeper throughout the night. 

On top of that, the cover features silver fibres, known for their antibacterial and moisture-absorbing properties, thus contributing to a cleaner and fresher sleep.

Last but not least, this Dormeo Fresh model is one of the most affordable on the market, giving you excellent value for money in addition to cool nights.

Unlike some models that only have one or two temperature-regulating features, the complete design of the Ergoflex 5G mattress is dedicated to providing sleepers with cool nights.  

The cooling technologies incorporated in the mattress include:

• An outer Tencel layer that protects the mattress and lets it breathe through the sides with 3D mesh panels.
• A unique 5cm Cool-Sleep layer in the core to promote ventilation and prevent heat buildup. 
• High-density open-cell memory foam that avoids hot air retention more effectively than any foam bed while supporting, relieving pressure, and isolating motion at the same time. 

In addition to all these great cooling features, the Ergoflex is also perfect for people suffering from allergies.  The protective cover is machine-washable, while all the materials are Certi-Pur & OEKO-TEX 100 certified. Knowing this, you can be certain that they are hypoallergenic and toxic-free.

Handcrafted in the UK, this medium-firm mattress incorporates the company’s unique ActiCool quilted cover—a fabric with cooling properties to help hot sleepers from overheating during the night. 

Another key benefit of this cooling mattress is the inclusion of ActiGel and PurFibre sections. Both of these layers are designed to increase airflow throughout the mattress, helping with temperature regulation.

Finally, the mattress (depending on the size) has over 1000 pocket springs that keep it steady and boost breathability. This layer, combined with the zoned & profiled foam in the top, provides side sleepers with the support and contouring they need for a good night’s rest.

In addition to hot sleepers, users suffering from sore joints and backs will also love this mattress. The 28 cm deep orthopaedic bed features two layers of pocketed springs for optimal spinal alignment and pressure-relieving comfort.
