Product Presentation
The Naturalex Brand
Naturalex is a European brand specializing in foam and hybrid mattresses. Present on Amazon for several years, it has built a solid reputation thanks to a wide range covering all budgets, from the entry-level PerfectSleep to the high-end Bio Premium models. The brand claims European manufacturing, a notable point in a sector often marked by untraceable offshore productions.
With over 13,662 reviews on Amazon France and a rating of 4.1/5, the PerfectSleep is one of the most acclaimed mattresses in its category. For this price, buyers are generally satisfied.
Technical Composition
Blue Latex Comfort Layer The Naturalex signature: a comfort foam with elastic properties similar to natural latex, without the price. The result is a livelier bounce than simple polyurethane foam, better adaptation to body shapes, and improved durability. This is the main difference compared to competitors at the same price.
Memory Foam A viscoelastic layer that conforms to pressure points (shoulders, lumbar, hips) and reduces tension points. The thickness is not that of a premium mattress, but it is sufficient for noticeable relief.
Support Base The firm foam base ensures overall body support and the longevity of the mattress over time.
The 7 Support Zones The PerfectSleep divides the surface into seven zones with distinct firmness levels. The head, shoulders, arms, lumbar, pelvis, legs, and feet each benefit from tailored support. This technology, usually reserved for premium mattresses, is a real added value at this price.

Our Testing Experience
Reception and Installation
The PerfectSleep arrives compressed in a vacuum-sealed box, convenient for stairs and tight spaces. Decompression takes about 30 to 60 minutes to regain full thickness, with a slight smell of new foam that dissipates within a few hours with good ventilation.
Installation is simple, and the weight of 6 kg (for the 90x190) makes handling easy. A real difference compared to premium mattresses that often exceed 30 kg.
Comfort by Position
Back Sleeper: Good surprise. The 7 support zones really make a noticeable difference. Lumbar support is adequate, and the spine is well supported. For this position, the PerfectSleep performs very well against competitors that are twice as expensive.
Side Sleeper: Satisfactory but not exceptional. The Blue Latex layer cushions the shoulders and hips, but the thickness of 16 cm limits pressure point absorption for heavier body types. Individuals under 80 kg will be very comfortable.
Stomach Sleeper: Acceptable. The firmness of the base prevents sagging in the lumbar area. Like all foam mattresses, this is not the ideal configuration.
Thermal Management
The summer/winter side is a commendable feature. The summer side is slightly more breathable and cool due to a breathable fabric; the winter side offers a softer surface. This is a practical solution that addresses one of the classic drawbacks of foam mattresses in hot weather.
Motion Isolation
Good isolation for this price level. The memory foam absorbs vibrations well. Nighttime movements do not significantly disturb a partner.
After 3 Weeks
The mattress retains its initial firmness without signs of sagging. The 5-year warranty is reassuring, and Amazon reviews mention mattresses still performing well after 2 to 3 years of regular use.

Strengths / Weaknesses
What We Liked
A price hard to beat At under 70 euros for a 90x190, the PerfectSleep has virtually no direct competition with this level of technology. This is its strong argument.
Blue Latex Technology The Blue Latex comfort layer is noticeable from the first nights. The bounce is livelier than on cheap polyurethane.
The 7 Support Zones Rare at this price. The differentiation of zones is tangible, especially for lumbar support.
Summer/Winter Reversibility A practical feature that extends use throughout the year.
European Manufacturing A guarantee of quality and traceability appreciated in the sector.
Lightweight and Easy to Handle 6 kg for a 90x190: a mattress that one person can move effortlessly. Ideal for studios, student residences, rental properties.
What We Liked Less
The 16 cm Thickness This is the main limitation. For individuals over 90 to 100 kg, 16 cm may not be sufficient.
Long-Term Durability At this price, the materials cannot compete with those of a 400-euro mattress. Consider a replacement after 5 to 7 years of intensive use.
No Extended Trial The Amazon return policy is standard. No 100-night trial like with Tediber or Emma.
Who Is It For?
This mattress is for you if...
You have a tight budget Under 100 euros, there is nothing better on the market. Whether you are equipping a student studio, a guest room, or a first apartment, the PerfectSleep does the job without breaking the bank.
You are a student or a mobile tenant Its very low weight (6 kg in 90x190) makes it the ideal mattress for those who move often.
You are looking for a mattress for a secondary room For a guest room, a secondary residence, or an Airbnb rental, it is a significantly better option than its price suggests.
You sleep alone and weigh less than 90 kg In this configuration, it competes comfortably with mattresses twice as expensive.
It is less suitable if...
- You weigh more than 90 to 100 kg
- You have serious and chronic back problems
- You want a primary mattress for 10 years or more without compromise

Final Verdict
The Naturalex PerfectSleep is the best mattress you can buy under 100 euros on Amazon France. It is not a perfect mattress: its 16 cm thickness and entry-level materials have their limits. But in its category and price segment, it is hard to do better.
If you are looking for a primary mattress for the next 10 years, save up and upgrade. But if you have a tight budget or a secondary need, the PerfectSleep checks all the boxes: Blue Latex, 7 zones, reversible, made in Europe, over 13,000 positive reviews.
At this price, there is no reason to pass it up.
Final Rating: 7/10
