Information Regarding Material Options:
We offer a wide range of material options for your aircraft interior. Some of the Pros and Cons of each specific material are listed below. Materials are interchangable and mixable on all of our interior kits. In addition to the materials listed, we can also accomodate other requests. Just contact us!
Artificial Leather -
Often refered to as Ultra-Leather, this is a modern Polyurethane material that is available in hundreds of colors, textures, and different finishes. We use at a minimum Automotive Grade Artificial Leathers that have excellent wear resistance, color fastness, and are burn resistant. We also offer Artificial Leathers applicable to the aviaition industry, in that they are certified to conform to FAR 25.853 Burn Specifications. The material is easy to care for and clean, and is relatively inexpensive compared to Microfabrics and Real Leather. Artificial Leather is often heavier than microfabrics and some Leathers.
Real Leather -
When it comes to durability, long life, wear resistance, and comfort, nothing does it better than Real Leather. All of our Leather (unless specifically requested) , is chemically tanned and dyed, and offer superb abrasion resistance and color fastness. Our standard leathers are Automotive quality leathers that are designed and tested for the modern day Automotive environment; extreme temperature variations and the robust requirements of the user will have little effect on Real Leather. Real Leather is expensive compared to its Artificial counterpart, and requires more care in the form of UV protectant and Leather care products. Cleaning of real leather is simple, and can be accomplished with warm water and mild detergent.
Microfabric-
Microfabric, also known as Alcantara, Comfort, or Ultrasuede, is a high qualtity polyurethane fabric. Modern Microfabrics have a velour or suede type pile on the surface. The material is often used as a substitute for leather or artificial leather, and provides comfort, excellent durability, light fastness, and stain resistance. Our standard Microfabrics are burn resistant, and are available with FAR 25.853 certification. Cleaning can be accomplished with a damp cloth, or with a chemical cleaner for tough stains.
Burn Resistance-
All of our materials are burn resitant, and at a minimum, are certified to FMVSS302, which is applicable to Automotive interiors. We also have a large selection of materials that we can offer that are certified to FAR 25.853/JAR 25.853.

Foam Options-
Our Standard Seats are all constructed using multipe layers of different density Polyurethane Foams, which are built to vary support according to weight distribution of a seated passenger.

In addtion to our Standard Foam builds, we also offer the option of upgrading the seats using Viscoelastic (Memory / Space Foam) for customers who wish to do so.
