Aircraft Upholstery Materials: Leather, Vinyl, Documentation & Buying Help
Short answer: Start with an upholstery material whose applicable flammability information can be documented for the material you are buying. Carolyn Fabrics supplies Slipstream aviation leather by the full hide, and Spirit Millennium aviation vinyl by the yard. The responsible installer and applicable approval authority must confirm the material, construction, records, and finished installation for the specific aircraft.
Best vinyl for aircraft seats: what to verify
Carolyn Fabrics’ primary aviation-vinyl starting point is Spirit Millennium. The manufacturer lists the material as meeting FAR 25.853(a), and required manufacturer documentation can be requested with the order. That makes Spirit a practical material to review; it is not blanket approval for every aircraft, seat, construction, or installation.
Before ordering, confirm all six parts of the decision:
- Material record: what manufacturer or test information is available and when it must be requested.
- Project applicability: what the responsible installer or approval authority requires.
- Workability: the contours, inserts, boxing, seams, and construction the shop plans to sew.
- Care: whether the current product-care instructions fit the expected use.
- Color and hand: how the real material looks and feels in the cabin’s actual light.
- Quantity: the complete pattern layout, cutting allowance, matching, and any planned repair stock.
Spirit is sold by the yard at a consistent 54-inch width. Choose the color on the Spirit Millennium product page and use its Sample option to order a physical swatch before committing to cut yardage. Required manufacturer documentation must be requested through the current product-page selection with the order.
Choose aviation leather when you want a natural premium material
Slipstream Aviation Leather is sold by the full hide only. It is a natural material, so the hide shape, grain, markings, and panel layout affect usable yield. Matching material burn-test documentation is automatically included with every full hide and is matched to the shipped material and production order.
To check one color, choose the color on the Slipstream product page and order the real-leather swatch. To compare the complete current line, use the complete Slipstream sample deck.
Aviation vinyl vs. aviation leather
| Decision | Aviation vinyl | Aviation leather |
|---|---|---|
| Buying unit | Linear yard | Full hide |
| Planning shape | Consistent roll width | Natural, irregular hide shape |
| Appearance | Repeatable manufactured surface | Natural grain and variation |
| Workability | Predictable width; contours and construction still matter | Requires hide layout, edge, mark, and yield planning |
| Care | Follow the exact vinyl care guidance | Use leather-appropriate care |
| Documentation | Request manufacturer burn documentation with the Spirit order; it is not included automatically | Matching material burn-test documentation is automatically included with every full hide |
Neither material is universally better. Vinyl often leads when predictable yardage and routine maintenance matter most. Leather leads when natural appearance and feel justify full-hide planning and a larger material commitment. Use the aviation leather versus vinyl comparison for the full decision process.
Marine durability is not aircraft documentation
A marine vinyl may perform well against sun, water, mildew, or outdoor cleaning and still lack the material record needed for an aircraft project. Do not substitute an ordinary marine or automotive vinyl solely because it looks similar or carries a high durability result. Read Can Marine Vinyl Be Used in an Aircraft? before making a substitution.
What FAR 25.853 material documentation does—and does not—mean
FAR 25.853 addresses flammability requirements for aircraft-interior materials in its applicable context. A material listing, test record, or supplier document can support material review. It does not approve an aircraft, seat assembly, cushion system, adhesive, seam, installation method, or completed interior.
For Spirit Millennium, request the manufacturer burn documentation when ordering; it is not included automatically and may not be available after shipment. For Slipstream, matching material burn-test documentation is automatically included with every full hide. Keep the shipped-material identification, invoice, and matched production-order documentation together. Before cutting, compare the product, color, quantity, production information, and document to the actual order.
Read the FAR 25.853 material explainer and understand burn-test and supplier-document terminology.
Foam and thread are separate decisions
Carolyn Fabrics does not supply aircraft seat-cushion foam, aviation-rated thread, or aviation-rated adhesive. We supply the face material and its available documentation. Source foam, thread, and adhesive from an aviation supplier to the aircraft and construction specification, and confirm the complete seat build with the responsible professional.
Thread must be chosen for the face material, seam design, needle and machine setup, color, and project requirements. Do not assume that the face-material document covers thread, foam, adhesive, backing, or a finished assembly. Read how to choose thread for aircraft upholstery.
Order in the right sequence
- Confirm the project and approval basis. Ask what material record is required before choosing or cutting.
- Sample the exact material. Check color, grain, gloss, hand, and coordination in the cabin’s actual light.
- Plan the complete quantity. Vinyl uses 54-inch yardage; leather requires full-hide layout and cutting allowance. Use the aircraft-seat material planning guide rather than a universal seat-pair estimate.
- Order the complete quantity together. Reduce later color, production-order, availability, and missing-document risk.
- Handle documentation by product. Request Spirit documentation with the order; Slipstream documentation is automatically included with every full hide.
- Receive and verify before cutting. Use the aircraft upholstery material receiving checklist.
Aviation leather buying answers
How much is one Slipstream hide delivered?
Slipstream is sold by the full hide only. Check the current Slipstream product page for the current hide price and shipping terms before ordering.
Is material-test documentation available?
Matching material burn-test documentation is automatically included with every full hide. It is matched to the shipped material and production order.
What does that documentation mean?
The documentation applies to the supplied leather and supports material review for the project. It is not approval of an aircraft, seat, cabin, or finished installation. The installer and applicable approval authority determine acceptability for the specific project.
How much material is one full hide?
A current Slipstream hide averages approximately 50–55 square feet. Under the upholstery trade planning allowance of 18 square feet per yard, that is roughly 2.5–3 yards of 54-inch upholstery material. This is a planning estimate, not a cutting guarantee.
How many hides does my project need?
Start with the complete yardage estimate, divide by roughly 2.5–3 yards per hide, then round up to full hides. Natural shape, markings, panel size, matching, and the cutting layout can reduce usable yield.
Can I check all 32 colors before choosing a hide?
The current complete Slipstream sample deck contains real leather swatches of all 32 colors so the customer, shop, or installer can compare color, grain, and hand before a full-hide order.
What thread should I use?
Choose upholstery thread for the exact face material, seam design, needle and machine setup, color, and project requirements. Carolyn Fabrics can help coordinate color, but the responsible shop must test the complete construction.
Is the leather the same thing as an approved finished aircraft interior?
No. Carolyn Fabrics supplies upholstery materials and available material-test documentation. The installer and applicable approval authority determine acceptability of the construction and finished installation for the specific aircraft.
