The Solitude Seat Frame and Foam Kit provides an untrimmed foundation for creating a period-style fixed bucket seat for Porsche 356 models from 1950 to 1965. This version has provisions for a 5-point belt arrangement and comes with rosettes to finish the belt openings. 

What This Product Does

A seat frame kit contains the main structural and cushioning elements needed before the upholstery stage. Rather than supplying a completely trimmed seat, it allows a vehicle trimmer to finish the seat in leather, vinyl or fabric selected to complement the existing cabin. This approach is suitable for restoration projects and individually specified interiors where the covering, stitching and piping are chosen separately.

The Solitude design takes inspiration from sports seats associated with Porsche 356 Roadster, Speedster, GT and Outlaw-style builds. Its fixed bucket profile combines a tubular frame with flexible suspension belts and shaped padding. The defined sides help establish a supported seating position while retaining an appearance suited to a classic 356 interior.

Functions

• Provides the structural foundation for a complete upholstered seat
• Uses flexible suspension belts beneath the cushion area
• Supplies pre-shaped padding for the seat base, back and sides
• Allows the upholstery material and finishing details to be selected separately
• Provides openings for use with an appropriate 5-point belt arrangement
• Includes rosettes for a neat finish around the belt cut-outs

Technical Details

• Protected tubular-steel frame construction
• Fixed bucket-seat configuration without an integral recline mechanism
• Duralastic suspension system beneath the seating surface
• Kit contains the frame, suspension belts, shaped foam, cushion and headrest
• Fire-resistant foam construction
• Approximate untrimmed kit weight: 7.3 kg

Symptoms of Fault

• Original padding has collapsed, hardened or developed an uneven shape
• The existing cushion sags and no longer offers consistent support
• Corrosion, fatigue or previous repairs have affected the original frame
• Backrest or side support has deteriorated
• Damaged upholstery has revealed worn foam or suspension components
• A complete seat foundation is needed for an interior restoration

Why Replacement Matters

Renewing the frame, suspension and foam as a complete foundation helps the finished upholstery retain its intended shape. It also avoids installing new covers over deteriorated padding or weakened structural parts. As the seat itself is fixed, its final height and angle depend on the runners, brackets and mounting arrangement used in the vehicle. Seat mounting points, belt anchorages and harness routing are safety-critical; installation should therefore use suitable vehicle-specific hardware and be checked by an experienced specialist.
