The Flex Nube Foam Mattress is the best-selling mattress in Flex history.
In this renewed version of the Nube Mattress, the materials and technologies of the original model have been fully respected, helping this mattress remain one of the most highly rated models in its category.
Among its advantages, the first is its mixed foam padding with highly breathable hypoallergenic fibres, offering a very adaptable and comfortable welcome when lying down.
Secondly, it has a pocket spring core designed for maximum sleeping independence, providing ideal pressure relief across every area of the body. This spring block helps prevent movement from being transmitted from one side of the mattress to the other, making it perfect for couples who want undisturbed sleep.
Another reason why it stands out is the combination of the Commodo+® and Confort System+® technologies patented by Flex, which offer a higher level of pressure relief during sleep while helping distribute body weight more evenly across the mattress surface.
At Colchón Exprés, we recommend placing this mattress on a firm upholstered bed base or storage bed to get the best performance from your sleep equipment. We do not recommend using it on a slatted bed base or adjustable bed.
If you like the characteristics of this mattress but are looking for extra firmness, we recommend the Nimbus Mattress, also from Flex, with two firmness options, including a medium firmness option slightly higher than the Flex Nube and a superior firmness option that is much firmer.
Discover our irresistible savings pack offers! Complete your perfect rest with our exclusive packs that include: Flex Cloud Mattress, along with ideal accessories.
