Knothön™ began with a grandmother's wish.
When my first grandchild arrived, I knew exactly what I wanted for him.
I wanted him to be safe. I wanted him to be truly comfortable. And I wanted his nest to be so beautifully made that it would feel at home in a carefully designed space - not an intrusion, but a work of art that belonged there, that elevated the room rather than disrupting it.
I had spent over twenty years as an interior designer in Barcelona, creating spaces where families write their most important stories. I understood better than most what it means for every object in a home to earn its place — to be both beautiful and purposeful, both elegant and genuinely useful.
No nest I found came close to what I was looking for. None combined real safety with real comfort and real beauty. So I made one.
Leah Farchi Sultan, Founder & Creative Director, Knothon
Every Knothon nest is individually handcrafted in Barcelona by skilled artisans, with meticulous attention to safety, comfort, and beauty.
The only nest in its category built around a real mattress. Formally evaluated and approved by Dr. Sabrina Andara, Pediatrician and Infant Sleep Specialist. Individually numbered - each piece the only one of its kind.
Because those three things - safety, comfort, beauty - are not a tradeoff.
They are a standard.
A work of art that happens to be a baby nest.
Evaluated by a Pediatric Specialist
The Knothön nest — handcrafted in Barcelona, Spain — has been evaluated from a pediatric perspective, with particular attention to safety, breathability, and structural stability. Its artisanal design encourages back sleeping, the internationally recommended position for safe infant rest, while its breathable materials support healthy temperature regulation. Altogether, it offers a safe, stable, and well-ventilated environment aligned with current safe-sleep recommendations for infants.

I am Sabrina Andara, a Licensed Physician and Specialist in Pediatrics, with specific training in Infant Sleep. I accompany families with an integrative, human, evidence-based approach — combining my clinical experience as a pediatrician with my advanced training in infant sleep.
My interest in pediatric sleep began with the arrival of my son, which led me to specialize in this field so I could offer other families practical, safe, age-appropriate tools that support healthy rest from the very first months of life.
My mission is to care for the health of the littlest ones and improve families' quality of rest — always through respect, observation, and an individualized approach.
Clinical Evaluation
Having evaluated in person the nest designed by Knothön, I confirm that its structure, materials, and craftsmanship meet the essential criteria for a safe resting environment during the first months of life. The evaluation focused on fundamental aspects such as firmness, ventilation, breathability, structural stability, and the quality of the fabrics.
1. Integrated Mattress: Firmness, Comfort, and Ventilation
The Knothön nest integrates the Capazo Fresh mattress (My Baby Mattress), which combines an HR Cloud core (23 kg/m3) with a surface layer of Visco Innogel. This structure provides:
— Adequate internal firmness, preventing sinking and keeping the baby's airway safe.
— Moderate surface comfort, without compromising stability.
— Good ventilation, thanks to its Airtex mesh and internal structure.
Correct firmness is a key element in promoting safe sleep, reducing risks related to unstable positions or excessively soft surfaces.
2. Nest Fabrics: Breathability, Safety, and Artisanal Craftsmanship
The nest's fabrics are handcrafted in Barcelona with OEKO-TEX Standard 100 Class 1 certified materials, guaranteeing the absence of harmful substances and suitability for contact with newborns. The textile components are breathable, hypoallergenic, and safe, promoting proper temperature regulation and reducing risks associated with overheating.
3. Hand-Braided Protective Barrier and Lateral Ventilation
The protective barrier, handcrafted from 100% cotton tubular fabric with breathable, hypoallergenic fiber filling, provides stability and comfort without compromising ventilation. Its double-braided design and the natural air chambers between the braid and the mattress facilitate air circulation and reduce the risk of lateral entrapment.
4. Safety of the Complete Set
The mattress holds OEKO-TEX Class 1 certification and complies with the UNE-EN 16890 standard. The nest's design provides:
— Overall stability.
— Hypoallergenic and breathable materials.
— Safe finishes, with no loose or excessively soft elements.
5. Plagiocephaly Prevention
The uniform surface of the Capazo Fresh and its adequate firmness contribute to an even distribution of pressure across the occipital area, helping to prevent positional plagiocephaly.
6. Safe-Sleep Principles the Knothön Nest Fulfills
— A firm, stable surface — essential for maintaining airway alignment and encouraging correct posture during rest. This firmness is especially important because babies should always sleep on their back, the safest and internationally recommended position for reducing risks during sleep.
— Breathable, well-ventilated materials.
— Proper temperature regulation.
— Absence of soft or loose elements.
— Certified textiles.
— Structural stability that prevents lateral sinking.
Conclusion
The Knothön nest — handcrafted in Barcelona, Spain — offers a safe, stable, and well-ventilated environment for infant rest. Its artisanal craftsmanship, the use of certified and breathable fabrics, the hand-braided protective barrier, and the Capazo Fresh mattress form a technically sound set — respectful of the baby's safety and aligned with current recommendations on safe sleep, temperature regulation, and the prevention of positional plagiocephaly.

Every Knothön™ Nest is engineered with precision and handcrafted in Barcelona using certified, high-quality European materials selected for safety, breathability, durability, and structural integrity.
All components comply with European Union regulations and are OEKO-TEX® Standard 100 certified. Textiles are breathable, hypoallergenic, and free from harmful substances.
1. Mattress Core & Base Structure
At the heart of the Knothön™ Nest lies a structured mattress base designed to provide firm support without memory effect, promoting stable positioning and even weight distribution during supervised rest.
The design has been reviewed and approved by a pediatrician specializing in infant sleep.
Core Composition:
HR Cloud core (23 kg/m³) with Visco Innogel® top layer

Total Height: 8 cm
The firm mattress, with its HR Cloud core (23 kg/m³) and Visco Innogel® top layer, offers adequate internal firmness, moderate surface comfort, and good ventilation through the Airtex mesh. Proper firmness is essential for safe sleep and maintaining airway alignment.
Integrated Airtex mesh enhances ventilation and promotes continuous airflow.
This construction provides:
• Stable, structured support
• Even weight distribution
• No sinking or memory compression
• Long-term shape retention
The mattress base includes a discreet zipper, allowing the six-layer textile system to be removed for washing.
2. Six-Layer Textile System
The removable mattress cover is constructed using six engineered fabric layers:
• 3 layers of smooth upholstery fabric for structure and durability
• 2 layers of Boatherm Soft padding for cushioning
• 1 final layer of thermoregulating fabric (Bamboo Blend or 100% Cotton)
This layered construction supports:
• Breathability
• Temperature balance

3. Hand-Woven Protective Barrier
Surrounding the mattress is a 100% cotton tubular protective barrier, developed exclusively for Knothön™ and handcrafted in Barcelona.
The barrier is filled with breathable, hypoallergenic fiber certified under European Union standards.
Between the mattress base and the braided barrier, multiple integrated openings function as air chambers, supporting continuous airflow and circulation.
The double-braided structure is secured with a natural wooden clasp engraved with the Knothön™ isotype.
4. Signature Braided Bumper
The braided bumper is constructed from a single seamless cotton-filled tube, woven into a four-strand braid and finished with one continuous seam.
This refined construction:
• Enhances structural durability
• Minimizes exposed stitching
• Supports washability
• Protects delicate skin and nails
The bumper is detachable and may be repurposed for crib use.
5. Precision Fastening System
The mattress base and protective barrier are connected using specially designed fastening straps that ensure a secure and stable fit.
The exclusive design allows for quick, precise assembly while maintaining structural integrity.
Each Nest is delivered fully assembled, accompanied by a protective canvas fabric bag for storage and transport.
The Knothön™ isotype is embroidered on the mattress base, featured on the fabric bag and protective barrier, and engraved on the wooden clasp.
