Details

The Flex Nimbus Foam Mattress is an evolved version of the original Nimbus model, incorporating improved comfort technologies and a more adaptive sleep experience. One of its main innovations is the redesigned foam layer placed above the pocket spring core, now profiled on both sides to improve body adaptation and sleeping comfort.

This updated structure maintains all the benefits that made the Nimbus collection so popular, including its excellent adaptability, breathable comfort and pressure-relieving sleep experience.

Double comfort layers: combination of hypoallergenic fibres for breathable and soft comfort together with gel memory foam that improves adaptability and helps maintain fresher sleep throughout the night.
Medium-high feel: the Support-Pro Zone core provides slightly firmer support than the Flex Nube collection, making it especially suitable for heavier sleepers or couples looking for extra support.
Pocket Premium® Pro spring core: independent pocket springs adapt individually to body pressure, providing ergonomic support and excellent sleeping independence.
Excellent sleeping independence: ideal for couples, as movement on one side of the mattress is barely transferred to the other side.
Commodo+® system: comfort layer placed beneath the padding designed to distribute body weight evenly across the mattress surface.
Reinforced perimeter support: HR foam perimeter structure designed to improve stability, durability and edge support.
Confort System+®: high-density foam technology designed to improve pressure distribution and sleeping ergonomics.

The Flex Nimbus Foam Mattress combines adaptive comfort, premium spring support and breathable materials to help improve sleep quality and daily recovery.

At Colchón Exprés you can enjoy free delivery, installation and old mattress removal together with personalised advice from our sleep specialists.

SETI_87 has a IMC NORMAL*

Their rating of this mattress is:

"I sleep on my side and I find it to be a very comfortable mattress that I recommend. In addition, it does not give any heat because it does not stick to the body and in the store they told me that since the visco is not attached directly to the fabric, the air circulates better and gives more coolness, especially in summer, for very hot people like me."

This is the second time I order. It's the second time I've ordered on the page. Previously a mattress with a canapé and pillows and this time a mattress for another bed.

OF LIFE. Since I was little we have had Flex mattresses at home and each time they are improved. ¨¨As a button shows¨¨, with this model they have surpassed themselves. Every day I am happier with the choice. I tried it and decided right away.

Very comfortable. The truth is that both my wife and I are very happy with the quality and comfort of the mattress, we have the feeling that it envelops you and its firmness is perfect for us although that is very particular.

samir19-05-2026

Excellent mattress. An excellent purchase, very good quality and price, it is just what I was looking for in terms of firmness, I recommend it for hot people, who like the feeling of entering bed and that the mattress is cool. If we have to put a but, it is that with the sofa it is very high, and on the website it seemed to me that it came with a pillow as a gift but in my case I have not received anything.

Modesto Nuñez rodriguez19-05-2026

Nimbus mattress review. Magnificent mattress. We bought it in medium firmness and we are fully satisfied with the mattress and with the speed with which you sent it to us. Thank you very much for the gift of the two magnificent pillows that you have given us and for the price paid. The best on the market.
