Sold each

The Solitude Seat Frame and Foam Kit provides an untrimmed fixed-seat foundation for Porsche 356 models built from 1950 to 1965. Configured for a 3-point seat-belt installation, it allows the upholstery material, stitching, piping and final finish to be selected separately for a restoration or individually specified interior. 

Fits

• Porsche 356 1950–55
• Porsche 356A 1955–59
• Porsche 356B 1959–63
• Porsche 356C 1963–65

What This Product Does

A seat frame kit supplies the principal structural and cushioning components required before trimming. Instead of replacing the seat with a pre-upholstered unit, the frame, suspension and shaped padding can be handed to a vehicle trimmer for covering in suitable leather, vinyl or fabric. This enables the finished seat to complement the materials and detailing already used within the cabin.

The Solitude has a period-influenced profile developed for classic Porsche 356 Roadster, Speedster, GT and Outlaw-style projects. Its fixed bucket form provides more defined side support than a conventional comfort-seat shape while retaining proportions appropriate for a classic interior.

Functions

• Forms the structural and padded base for a complete upholstered seat
• Uses flexible suspension belts beneath the seating area
• Provides shaped cushioning for the base, backrest and side sections
• Allows upholstery, stitching and piping to be specified independently
• Supports a more defined seating position within a classic 356 cabin
• Accommodates an installation intended for 3-point seat belts

Technical Details

• Protected tubular-steel frame
• Fixed bucket-seat construction without an integrated reclining mechanism
• Duralastic suspension belts beneath the cushion
• Fire-resistant foam material
• Includes frame, suspension belts, side and back foam, seat cushion and headrest
• Approximate untrimmed weight: 7.3 kg

Symptoms of Fault

• Seat foam has become hard, compressed or uneven
• The cushion sags or offers inconsistent support
• Corrosion, fatigue or earlier repairs have weakened the existing frame
• The backrest or side padding no longer retains its shape
• Worn upholstery has exposed damaged foam or suspension parts
• A complete foundation is required for a seat restoration

Why Replacement Matters

Renewing the frame, flexible suspension and padding together gives the trimmer a stable, correctly shaped base for the new upholstery. It also prevents fresh covers from being fitted over deteriorated foam or compromised structural components. As this is a fixed seat, the installed height and backrest angle are established through the selected runners, brackets and mounting arrangement. Seat mounts and belt anchorages are safety-critical, so suitable vehicle-specific hardware should be used and the completed installation checked by an experienced specialist.

FAQs

• Is upholstery supplied? No. The kit is untrimmed, allowing a vehicle trimmer to apply the chosen covering and finishing details.
• Which components are included? The kit comprises the tubular frame, suspension belts, shaped side and back foam, seat cushion and headrest.
• Does the backrest recline? No. It uses a fixed bucket structure; the final tilt and seating height depend on the installation hardware.
• Are runners and mounting brackets included? Suitable runners, brackets and fixings should be selected separately for the vehicle and required seating position.
• Can access behind the seat be retained? A compatible tilting mounting arrangement may be used where appropriate, subject to the vehicle and installation requirements.
