Details

Enjoy the new Flex Eternity Pocket Mattress and experience premium sleep comfort with one of the most advanced double pocket spring systems developed by Flex. Designed to provide balanced support, excellent adaptability and superior sleeping independence, this mattress delivers a refined and ergonomic sleep experience.

Its main advantage is the innovative double pocket spring core composed of a 5 cm Pocket Premium® Micro spring layer together with an 18 cm Pocket Premium® Pro spring block. This combination multiplies the benefits of pocket springs by adapting independently to every part of the body while improving spinal alignment and reducing pressure points.

The comfort layers combine hypoallergenic and thermal fibres with Double Soft Sense foam and the Comfort System® technology, creating a progressive and weightless comfort sensation while helping muscles relax during sleep.

The outer fabric contains a high percentage of viscose, offering an exceptionally soft touch and helping improve adaptability between the body and the comfort layers of the mattress.

The breathable materials used throughout the mattress promote continuous airflow and moisture evacuation, helping create a fresher and more comfortable sleep environment all year round.

With the quality guarantee of Flex and the service of Colchón Exprés, the Flex Eternity Pocket Mattress also includes free delivery, installation and old mattress removal in mainland Spain.
