Core Responsibilities

Primary Functions

Accurately measure and lay out patterns on fabrics, leather, and vinyl, ensuring efficient use of materials and minimizing waste while meeting design specifications and tolerances.
Cut foam, batting, fabric, leather and vinyl using both manual and CNC/automatic cutting equipment, following templates and graded patterns for consistent component shapes and sizes.
Operate industrial sewing machines (e.g., post-bed, cylinder-bed, heavy-duty zigzag, and overlock) to sew seams, welts, piping, zippers, and reinforcement panels to precise seam allowances and stitch types required by the product.
Assemble and fit upholstery components to frames or substrates, stretch and tack materials to achieve correct alignment, tension, and aesthetic finish on furniture, vehicle interiors, or marine seating.
Install foam and padding using adhesives, contact cement, and mechanical fasteners to achieve specified comfort, resilience, and ergonomics while following safety protocols for adhesives and curing times.
Perform tufting, channel sewing, pleating, welt application, buttoning, and decorative stitch work according to pattern instructions and sample approvals to meet design and quality standards.
Use pneumatic staple guns, tackers, and hand staplers to secure upholstery to wood, metal, or composite frames, ensuring staples are placed at appropriate spacing and depth to prevent pull-through or loose areas.
Trim, skive, and finish seams, edges, and openings using knives, skiving machines, and hand tools to create neat, seamless transitions and conceal raw edges as required by the product type.
Read and interpret technical drawings, bill of materials, work orders, and sample pieces to plan workflow and sequence operations for efficient production runs or one-off custom projects.
Perform repairs and reupholstery work on returned or refurbished items including patching, seam repair, foam replacement, and hardware replacement while documenting repair actions and parts used.
Fit and install hardware and components (zippers, snaps, buckles, grommets, tracks, seat belts, headrests) into upholstery assemblies to factory standards and safety requirements for automotive and marine applications.
Conduct in-process and final quality inspections, identify fit and finish defects, make corrective adjustments, and escalate recurring issues to supervisors to prevent repeat defects.
Maintain accurate production records, trim logs, and material usage sheets; report scrap, rework, and yield metrics to production management for continuous improvement.
Collaborate with pattern makers and designers to adjust templates for fit, comfort, or material behavior, providing practical feedback on manufacturability and assembly sequencing.
Set up, adjust, and maintain sewing machines and cutting equipment, replacing needles, presser feet, and performing minor mechanical adjustments to ensure consistent stitch quality and machine performance.
Prepare and glue, stitch, or mechanically secure laminated materials and composite assemblies, ensuring bond strength and visual continuity for multi-layer products.
Prioritize and sequence work based on production schedules, custom order deadlines, or service requests to meet customer or assembly line timelines with minimal downtime.
Train and mentor junior trimmers, apprentices, or temporary staff on best practices for cutting, sewing, and finishing while enforcing shop safety and quality expectations.
Follow and enforce safety procedures, personal protective equipment (PPE) requirements, lockout-tagout (LOTO) for machinery, and safe handling of solvents and adhesives used in upholstery work.
Participate in continuous improvement initiatives, suggest tooling or process improvements, and help implement standard work procedures to reduce costs or increase throughput.
Prepare prototypes, samples, and mock-ups for design approval stages, adjusting construction methods to meet aesthetics, durability, and cost targets for new product introductions.
Coordinate with shipping/receiving and inventory teams to ensure timely material replenishment, traceability of specialty leathers or fabrics, and proper storage to prevent damage or contamination.
Provide accurate time estimates for custom jobs and retrofits, communicate status to production planners and customers, and document deviations from quoted time or materials.

Secondary Functions

Assist with light machine maintenance, cleaning, and sharpening of cutting blades or skiving tools to maintain tooling readiness and part quality.
Support packaging and final assembly teams by performing last-mile trimming, tagging, and final fit checks before items are boxed or installed.
Help maintain organized tooling, jigs, templates, and sample libraries used for repeat runs and custom work, labeling parts for quick retrieval.
Participate in cross-functional meetings with design, production, and quality to troubleshoot recurring fit issues and reduce rework rates.
Maintain compliance records for fire-retardant treatments, material certificates, and regulatory labeling for automotive, marine, and contract seating products.
Assist with customer-facing activities when necessary, including measurements for on-site repairs, explaining repair options, and supporting order intake for custom upholstery services.
Document process changes and update standard operating procedures (SOPs) for trimming and sewing sequences to reflect best practices and safety improvements.
