Retention strength, tuft spacing, seam alignment, channel depth, cushion recovery, service access, and finished profile must match the approved master sample.
-
Button-Tufted Back & Arm Construction
Deep hand-set tufting creates the diamond back pattern and controlled channeling across the arms.
Guangdong, China
Button spacing, tuft depth, pull tension, leather strain, symmetry, seam placement, backing reinforcement, and long-term retention are inspected.
-
Optional Nailhead Trim System
The frame is prepared for either a clean no-nailhead configuration or evenly spaced decorative nailhead trim.
Guangdong, China
Nailhead material, finish, diameter, spacing jig, alignment, retention, substrate protection, and configuration accuracy are controlled.
-
Fixed Solid Rubberwood Legs
Load-bearing solid rubberwood legs provide the raised stance and stable floor contact.
Guangdong, China
Species verification, wood grade, moisture content, machining tolerance, joint integrity, mounting strength, and load performance are controlled.
-
Seadrift Wood Finish System
Multi-step Seadrift-tone finish protects the rubberwood legs while preserving visible grain character.
Guangdong, China
Color master, sanding schedule, stain absorption, sealer coverage, topcoat adhesion, chemical resistance, rub resistance, and batch consistency are approved.
-
Non-Marking Floor Glides
Low-profile floor contacts protect finished flooring and maintain stable installation.
Guangdong, China
Material, load capacity, attachment strength, height consistency, floor-contact finish, and finished-leg clearance are inspected.
-
Leather Sewing & Tufting Components
High-strength thread, reinforcement tape, interliners, tufting buttons, cushion retention, and dust covers support the tailored upholstery package.
