Product Information
Springbox reinforcement kit for the 2 front seats of Porsche 356 models from 1959 – 1965 with standard Recaro comfort seats. Contains 8 high resistance coils, 2 hoursehair panels and correction filling.

When replacing your front seat covers it is recommended to install our front seat reinforcement kit. It will provide you better ride comfort and increase the life of you new seat covers.

Solitude Seat Frame and Foam Kit - 3 Point Seat Belt
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.

Solitude Seat Frame and Foam Kit - 5 Point Seat Belt
Sold each

Fits

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


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.


FAQs

  • Does the kit include upholstery? No. It is supplied untrimmed so that a suitable trimmer can apply the required material and finish.
  • What comes with the kit? The principal components comprise the tubular frame, flexible suspension belts, formed padding, seat cushion and headrest.
  • Are the 5-point belt rosettes supplied? Yes. The surrounds used to finish the seat-belt cut-outs are included with this version.
  • Is the backrest adjustable? No. The Solitude uses a fixed bucket structure. Installed tilt and seating height are determined by the chosen brackets and runners.
  • Are vehicle mounting parts included? Suitable runners, brackets and fixings should be selected separately according to the vehicle and required seating position.
