What This Product Does

A seat frame kit is an untrimmed foundation rather than a fully finished seat. It combines the supporting structure, suspension and shaped padding needed before upholstery is fitted. A professional vehicle trimmer can then apply leather, vinyl, cloth or corduroy to suit the car's interior, allowing the covering, stitching and piping to be specified as part of the restoration.

The Spa-Francorchamps design is based on the shape of period sports seats used during the late 1960s and early 1970s. Its square-tube frame, formed cushioning and separate headrest create a classic bucket-seat profile suitable for period-inspired road, restoration and competition-style interiors. Openings are incorporated for a suitable 5-point belt installation, with the supplied rosettes providing a tidy edge around the cut-outs.

Functions

• Forms the structural and padded base for a complete upholstered seat
• Allows trim material, stitching and finishing details to be selected separately
• Uses flexible Duralastic suspension belts beneath the padded areas
• Provides shaped foam for the backrest and side sections
• Accommodates an appropriate 5-point belt arrangement
• Includes cut-out rosettes for finishing the belt openings

Technical Details

• Square steel-tube frame construction
• Kit includes the frame, Duralastic suspension belts, side and back foam, seat cushion and headrest
• Fire-resistant foam is used within this type of seat kit
• Prepared with openings for a 5-point belt configuration
• Seatbelt cut-out rosettes are supplied

Symptoms of Fault

• Original seat foam has compressed, hardened or lost its shape
• The cushion sags or provides uneven support
• Corrosion, fatigue or earlier repairs have affected the existing frame
• Suspension components beneath the seat have stretched or failed
• Worn upholstery has exposed deteriorated padding
• A complete untrimmed foundation is required for an interior rebuild

Why Replacement Matters

Starting with a complete frame and foam kit gives the trimmer a consistent structure on which to form and tension the upholstery. It avoids fitting new covers over tired padding or damaged supporting parts and allows the finished seat to be tailored to the vehicle's colour scheme and intended use. Final seat height, angle and fore-and-aft adjustment depend on the selected mounting brackets and runners. Seat mounts, belt anchorages and belt routing are safety-critical, so installation should use appropriate vehicle-specific hardware and be checked by a suitably experienced specialist.
