BESPOKE CAR
INTERIORS
Zonam is an Italian atelier based in Monza, specialising in the design, engineering and manufacture of bespoke automotive interiors. We act as a technical partner for private collectors, tuning firms and members of the Restomod movement, creating bespoke interiors for sports cars, luxury cars and classic cars, as well as one-off projects and small limited runs on an international scale.
By combining the fine craftsmanship of Italian leather with original equipment manufacturer (OEM) industrial processes, we manage the entire production cycle within our own facilities: from digital prototyping to laser cutting, from technical lamination to electronic coding.
PRECISE CHOICES
WE USE PREMIUM MATERIALS
The beauty of materials lies in their authenticity and the stories they tell.
At Zonam, we select only the finest materials, such as genuine Alcantara and premium natural fabrics, including 100% pure wool, chosen for their durability and the sense of harmony they bring to every interior.
GENUINE LEATHER
Premium and durable, genuine leather delivers comfort and luxurious finishes. Perfect for an exceptional driving experience.
ALCANTARA
An innovative, soft and durable material that combines elegance and performance.
PREMIUM FABRICS
Wool and natural fabrics selected for their quality, comfort and visual appeal. Materials that elevate interiors with a refined, textural and timeless character.
LAMINAZIONE 3MESH
MANUFACTURING
PHILOSOPHY
In 90% of our projects, automotive leather and Alcantara® are not bonded to conventional polyurethane foam, but are instead continuously heat-laminated with 3Mesh (three-dimensional spacer fabric) using industrial laminating equipment.
STRUCTURAL COMPARISON: 3MESH LAMINATION vs FOAM RUBBER
TRADITIONAL METHOD
Leather → Spray Adhesive → Polyurethane Foam
Result: Hydrolysis, crumbling and surface deformation.
ZONAM METHOD
Leather → Heat Lamination → 3Mesh Spacer Fabric
Result: 3D elasticity, shape recovery, breathability and long-term durability lasting decades.
The three-dimensional polyester structure of 3Mesh ensures that seat surfaces, dashboards and interior panels maintain a smooth, taut appearance even after years of compression and extreme temperature fluctuations, overcoming the durability limitations of conventional OEM upholstery.
Crazy Horse Leather
Brown Pull-Up leather with a rich texture and distinctive aged character.
IN-HOUSE MACHINERY & EQUIPMENT
PRODUCTION DEPARTMENT
Unlike traditional upholstery workshops, Zonam has brought the entire production process in-house, ensuring complete quality control and consistent repeatability across B2B projects.
Fortuna Leather Skiving & Splitting Machines
Precision thinning of leather edges down to 0.3 mm.
Continuous Thermal Laminating Machines
For uniform and controlled material processing.
Ultrasonic Welding Machines
For reassembling OEM ABS/PP components.
Richpeace CNC 3-in-1
Quilting, perforation and embroidery in a single system.
Dürkopp Adler
Industrial sewing machines with triple-feed technology.
CNC Laser Systems
High-precision vector cutting and engraving.
Scope of Work
Our design expertise and in-house equipment enable us to upholster and reshape virtually any component, even those with the most complex geometries:
Sports and Ergonomic Seats: Custom upholstery, ergonomic foam reshaping, contrasting piping, geometric quilting and CNC embroidery.
Door Panels and Center Consoles: Redesign of interior side panels, integration of storage pockets, armrests, and perforated or laser-engraved inserts.
Dashboards and Instrument Panels: Full anti-glare upholstery in Alcantara® or Nappa leather, with precision leather skiving to ensure seamless stitching around air vents.
Headliners, Pillars and Steering Wheels: Breathable upholstery for upper cabin surfaces and custom-contoured steering wheel rims with a 12 o’clock center marker.
Acoustic Soundproofing
For Restomod projects and high-performance vehicles, driving comfort requires effective insulation from road noise and body resonance. We use Comfort Mat multilayer acoustic materials, treating the vehicle cabin with a targeted layered insulation system.
COMFORT MAT MULTILAYER ACOUSTIC INSULATION SYSTEM
LAYER 1: Vibration-Damping Mastic (Reduces body panel vibrations and resonance)
LAYER 2: Sound-Absorbing Insulation (Absorbs sound waves)
LAYER 3: High-Density Acoustic Barrier (Blocks noise transmission)
Areas of Application: Complete floorpan, engine firewall, inner wheel arches, doors, roof and luggage compartment.
Benefits: Reduced cabin noise levels (dB), minimized metallic resonance and a significant improvement in audio system sound quality.
ONE-OFF PROJECTS & B2B COLLABORATIONS
RESTOMOD
PROJECTS
We work alongside boutique car builders, specialist coachbuilders, and low-volume manufacturers to create limited production runs. Through the digital vectorization of patterns, cutting, perforation, and stitching parameters are stored to ensure complete production repeatability.
Through our established network of trusted partners, we also coordinate:
- Bespoke inserts in autoclave-cured carbon fiber and premium wood veneers.
- Application of Paint Protection Film (PPF) and Vehicle Wrapping.
- Bodywork, mechatronics, and automotive electrical services, without requiring customers to transport their vehicles between facilities.
