What type of mattress is the Flex Fresh Cool Multielástic?

The Fresh Cool technology has been awarded the 2026 Trofeo del Hogar Top Innovation Prize in the Innovation category, chosen by consumers through blind testing under real-use conditions, monitored and supervised by specialist laboratories.

What firmness does it have?

High firmness , designed for those who prefer a solid, stable feel without any sinking sensation.

Details

The Flex Fresh Cool Multielastic Mattress is one of the most distinguished models in Flex's premium range — and the only one to receive the Trofeo del Hogar 2026 Top Innovation Award in the Innovation category, a distinction earned through consumer blind tests conducted under real-use conditions in specialist laboratories. For those seeking a high-firmness mattress with active thermal comfort technology, this model brings a combination no other distributor can offer.

Its 16 cm Multielástic® continuous coil core is the engine behind its firm, stable behaviour: a compact structure of double-thread continuous coils with a cross-spiral arrangement that responds to pressure with excellent resilience and long-term durability. The outcome is a solid, uniform sleep surface with no sagging — designed for sleepers who value consistent, uninterrupted support through the night.

The defining feature of this model is its reversible double-sided design, with technically differentiated fabrics tailored to each season. Face A uses a Stretch fabric with Fresh Cool technology — a dual-action system that cools the surface on contact with skin and reduces heat build-up, ideal for warmer months. Face B features a high-pile Stretch Premium fabric with Optigrade®, a thermal regulator that keeps temperature and humidity balanced for a comfortable sleep in colder conditions.

The interior comfort system brings together open-cell viscoelastic foam for adaptive pressure relief, hypoallergenic fibres, Commodo+® for progressive cushioning, Total Protect antibacterial treatment, Confort System+® for even weight distribution, and Felt Protect to preserve the internal structure over time.

At Colchón Exprés, the Flex Fresh Cool Multielastic is available with free delivery, installation, and removal of your old mattress. If you'd prefer the same Fresh Cool reversible system with an independent spring core, explore the Flex Fresh Cool Pocket Mattress.

Who is it recommended for?

Sleepers who prefer a firm, stable surface with no risk of sagging.
Those who feel too warm in summer or too cold in winter — the reversible design adapts to each season.
Couples or solo sleepers with similar firmness needs.
People with allergies or sensitivities: hypoallergenic fillings and Total Protect antibacterial treatment.
Those looking for a durable, award-winning mattress at a great value price point.
