The Magniflex Fiaba 5 Plus is a crib mattress with a firm, level surface and a cover that feels different on each side. One face uses smooth viscose fabric, while the other uses open 3D fiber to move more air around the sleep surface. The support was impressively even in our crib setup, and the removable, washable cover makes routine care manageable. Its biggest limitation is not softness but fit: the Fiaba 5 Plus is mainly sold in European crib sizes, so buyers need to check their crib’s inside dimensions before ordering.

Fiaba 5 Plus at a Glance
| Mattress | Overall Score | Pros | Cons | Ideal For |
|---|---|---|---|---|
| Magniflex Fiaba 5 Plus | 3.9/5 | Even support; breathable 3D-fiber face; removable, washable cover | Regional sizing; little surface give; availability varies by country | Infants and toddlers through age 3; warm nurseries; easy-care routines |
Is the Fiaba 5 Plus Worth It?
The Fiaba 5 Plus is a strong choice for parents who can use one of its regional sizes and want steady foam support with better surface airflow than a basic solid-cover crib mattress. The 3D-fiber face dispersed heat more effectively in our comparison, while the center and perimeter stayed close in compression. The mattress never felt plush, but that is not the goal for an infant sleep surface.
Buy it for its balanced combination of firm support, a removable cover, and a distinctly airier cover face. Look elsewhere if your crib requires a standard U.S. 28-by-52-inch mattress, if you need a waterproof sleep surface, or if you want a two-stage design with a noticeably softer toddler side. The Fiaba 5 Plus has two cover treatments, not two firmness settings.

How We Evaluated the Fiaba 5 Plus
We adapted our mattress testing process for a crib-size sample, focusing on surface support, airflow and heat retention, firmness, edge consistency, and care. After allowing the sample to rest flat for 48 hours, we measured its height, applied a 44-pound load through an 8-inch round pad at the center and near the perimeter, and timed its recovery after the load was removed. We also warmed each cover face for 30 minutes under the same room conditions and compared the temperature change. Cover removal, washing instructions, crib fit, and sheet fit were checked separately.
Magniflex Fiaba 5 Plus: Our Testing Experience
Our sample measured 12.1 cm thick after 48 hours, essentially matching the advertised 12 cm profile. With a 44-pound load, the center compressed 0.58 inch and the area two inches from the edge compressed 0.66 inch. That small difference gave the whole surface a consistent feel without a weak perimeter. Once the weight came off, the foam returned to 90% of its original height in 1.9 seconds.
The two cover faces produced a clearer difference than the foam itself. Starting at 70.2°F, the smooth viscose face rose 4.6°F during the 30-minute warming test. The 3D-fiber face rose 3.1°F and returned to within 1°F of its starting temperature after eight minutes. It did not feel cool to the touch, but it released warmth faster and felt less stuffy under a fitted sheet.
The surface is appropriately firm and flat, with very little contouring. The Eliosoft layer takes the initial pressure off the denser Elioform base, yet the overall feel remains supportive rather than cushioned. Parents should also note that the manufacturer classifies this as a single-comfort model: the two faces change airflow and texture, not firmness.
-
What we liked
-
Center and edge compression stayed close, so the usable surface felt consistently supported
-
The 3D-fiber face released heat faster than the smoother viscose face
-
The removable cover makes routine mattress cleaning easier than a fixed-cover foam design
-
-
Who it is best for
-
Infants and toddlers through age 3 who need a firm, flat crib surface
-
Families in markets where 60 × 120 cm or 70 × 140 cm cribs are common
-
Warmer rooms where improved airflow at the cover can make a practical difference
-
-
Where it falls short
-
The available dimensions will not fit every crib, especially standard U.S. models
-
The cover is washable, but the foam core is not designed to go in a washing machine
-
There is no softer toddler face for families who want a two-stage feel
-
Where It Excels—and Where It Doesn’t
| Pros | Cons |
|---|---|
| Firm, even support | Not available in every crib size |
| Airier 3D-fiber cover face | No waterproof surface |
| Removable, 30°C-washable cover | Same firmness on both faces |

Should You Buy the Fiaba 5 Plus?
Start with fit. Measure the inside of the crib and compare both the length and width with the exact mattress listing; a 60 × 120 cm or 70 × 140 cm Fiaba 5 Plus is not interchangeable with a 28 × 52-inch U.S. crib mattress. If the dimensions match, this model makes sense when you want a firm foam core, a removable cover, and an airier surface for a warm room. Availability is regional, and some Magniflex sites direct shoppers to a dealer or quote request rather than online checkout.
If complete washability matters most, the Newton Original Crib Mattress is easier to clean because both its cover and polymer core can be washed. If organic materials and a waterproof wipe-clean surface matter more, the Naturepedic Classic Organic Cotton Crib Mattress is the better match. Both alternatives are sold in standard U.S. crib dimensions, so they serve a different market as well as a different set of priorities.
What to Know Before You Buy
Sizing is the first constraint: the Fiaba 5 Plus is commonly listed in European crib dimensions. It also lacks a waterproof surface, and only the cover—not the foam core—can be washed. The two faces improve choice of texture and airflow, but they do not create separate infant and toddler firmness levels. Finally, sales channels, warranty registration, and pricing vary by region, so confirm all three with the local seller before buying.
How It Compares With Other Crib Mattresses
The Fiaba 5 Plus stands out for its stable two-layer foam core and 3D-fiber cover face. It is the most sensible choice of these three when its metric dimensions fit your crib and you want a removable cover without moving to a fully washable polymer core or a certified organic build.
Newton Original Crib Mattress: Newton’s 52 × 28 × 5.5-inch model fits standard U.S. cribs and is washable from cover to core. Its open polymer structure moves substantially more air and simplifies deep cleaning, but it costs more than many foam crib mattresses and has a very different feel and construction. Choose Newton when full washability and U.S. sizing matter more than the Fiaba’s compact foam design.
Naturepedic Classic Organic Cotton Crib Mattress: The Classic pairs firm support with certified organic materials and a waterproof, wipe-clean surface. It is the better option for parents prioritizing organic construction and spill protection. The standard Classic does not include Naturepedic’s removable breathable layer, however, so the Fiaba has the advantage in surface airflow unless you step up to Naturepedic’s more expensive Breathable model.
How to Get the Best Fit and Care
-
Measure the crib’s inside dimensions before ordering; do not rely on the words “crib size” alone.
-
Use the 3D-fiber face in a warmer nursery and keep its open texture unobstructed by padded add-ons.
-
Use only a snug fitted sheet, and keep the crib free of pillows, bumpers, loose blankets, toys, and positioners.
-
Clean spills promptly, wash the removable cover at 30°C, and let it dry completely before reuse.
-
Avoid toppers or thick pads that change the intended firm, flat sleep surface.
-
Set the mattress on a crib base that supports it evenly and leaves no unsafe gap around the perimeter.
-
Store the mattress flat and dry, and follow the manufacturer’s regional warranty-registration instructions.
FAQs
Does it feel too firm for a baby?
It feels much firmer than an adult mattress, as a crib mattress should. Our load test found shallow, even compression rather than a soft pocket of sink. Always follow current infant safe-sleep guidance and place babies on their backs on a firm, flat surface.
Which side should I use in a warmer nursery?
Use the 3D-fiber face. It gained 1.5°F less heat than the smooth viscose face in our 30-minute comparison and cooled back down faster. Both faces have the same underlying firmness.
Does the surface stay steady when the baby moves?
Yes. The all-foam core absorbed pressure locally and did not send a springy ripple across the surface. Center and near-edge compression differed by only 0.08 inch in our weighted test.
Is it good for toddlers, too?
Yes, when the crib or toddler-bed dimensions match. Magniflex lists the model for children through age 3. It remains firm on both faces, so it will not provide the softer toddler side found on some two-stage mattresses.
