Details

The Relax Magnum adjustable firmness mattress is the ideal solution for those who want a sleep surface that is fully tailored to their individual needs. Thanks to its personalised design, you can choose between two firmness levels — Very Firm (FIRM) or Medium-Firm (MEDIUM) — via a high-density technical layer that adjusts its response to body pressure according to the chosen model, giving you precise control over how your mattress feels from night one.

The titanium-treated pocket spring core with 7 differentiated comfort zones ensures excellent body adaptation and differentiated support across every area of the body — from the shoulders and lumbar zone to the legs — promoting correct spinal alignment in any sleep position. Three ergonomic foam layers of different densities work above the spring core to deliver a progressive, pressure-free feel with outstanding sleep independence, making this mattress a particularly strong choice for couples.

The dual-sided construction adds a further layer of versatility: the summer face features natural cotton and linen fibres for a consistently fresh sleep environment throughout warmer months, while the winter face incorporates wool and cashmere fibres for a warmer, more cocooning feel during the cooler season. The memory foam upholstery with PCM thermo-regulating particles actively manages temperature at the sleep surface across both sides of the year. The HR foam perimeter encapsulation maximises the usable sleep area, adds structural stability and ensures the mattress holds its shape and performance over the long term. Combined with 100% natural materials, a continuous ventilation system and a hygienic treatment, the Relax Magnum is a durable, breathable and genuinely premium sleep solution. Made in Spain, with free delivery, assembly and removal of your old mattress included.

Aranzazu19-05-2026

Option to choose firmness and size. Good mattress, comfortable and with the option to choose firmness and size, both width and length.

Pedro19-05-2026

Good firmness for 120kg. Very happy with the purchase so far. It may be too hard for some people (medium firmness) as I have read some comments, in my case with 120 kilos dpm.

Montse19-05-2026

Delivered ahead of time. This mattress is very comfortable, just as the description said. They delivered it to us ahead of time.

Rodrigo19-05-2026

It looks quality. Good firmness. It looks quality. We will see with time.

Marta19-05-2026

I have been suffering from lumbar problems for years.. I finally found the solution to my back problem! (with the previous mattress I woke up every day with pain). I have been suffering from lower back problems for years and although I supposedly had a good mattress, the pain persisted continuously, not allowing me a good rest. But thanks to the firmness (I chose the Firm) and layers that make up this mattress, the problem has disappeared. (Its 7 rest areas and the quality of the materials also help). I can say that it is the best money spent.

Cristian Mercogliano 19-05-2026

The website where I bought it... great!. I bought the mattress for my 14 year old daughter. At first he didn't want a hard mattress, but he ended up loving it, it's firm, with springs, it rests super well, it's thick, approximately 32 cm The website where I bought it was great, I was a little suspicious because I didn't know it and a mattress is something special to buy, but they answered my questions, when I chose it, they confirmed it via email, they called me to confirm address and information Finally, the delivery man, although he called me to give me the day and time of delivery, they came at the time they wanted and I had to ask the neighbors for help to receive them. I recommend it!

Marisa Aldeguer19-05-2026

I love it! I have it in a 2nd residence. I love it, I haven't slept in it yet, I have it in a second home, I will release it soon!

Afrodita Aguirrebeña19-05-2026

A wonder!!. Since using it my back pain has appeared.

Carla V.19-05-2026

Firm but pleasant. My partner and I are older and in the end the mattresses never seem really firm to us. We are delighted with this mattress as it has the firmness we were looking for but the padding is very comfortable and soft. We have recommended the store to friends and family because from the beginning they gave us excellent treatment and very good advice.

MARIANA19-05-2026

FIRM AND COMFORTABLE. We were looking for a really high firmness, in other mattresses we have had we have never achieved the firmness we wanted and now finally with this mattress we have got it right! The attention of the advisors was a 10 from start to finish, they didn't help much. Good purchase, I would repeat.

ANA ORTEGA19-05-2026

HAPPY. Wonderful mattress with differentiated rest areas and maximum adaptability, highly recommended

CAROL19-05-2026

MAGNUM MEDIUM. We bought the mattress in medium firmness a month ago and we are very happy, my partner and I do not feel the movement of the other, which was the problem with our old mattress. It is very pleasant to lie down. The purchase of the mattress from the chat advice to the delivery has been excellent. Highly recommended

DARIO19-05-2026

FIRM BUT PLEASANT. Finally a mattress that is truly high in firmness without losing comfort. After having spent some time looking and thanks to the advice in the store, we opted for the firm magnum and so far everything is very good, we have been with this mattress for a couple of weeks and we have already noticed an improvement in the rest. I would recommend talking to the advisors, they always know how to advise you the best.

Relax Magnum. At first it was a good mattress, with the passage of time it was the worst I have ever had, it was too hard and pressure points appeared and it was very uncomfortable.

Francisca19-05-2026
