Step-by-step explanation:
The two types of upholstery commonly used for fabric coverings and cushions on aircraft are leather and vinyl. Leather is a natural material known for its durability and luxury appeal. It is often used in premium or executive cabins due to its comfort and high-end appearance. On the other hand, vinyl is a synthetic material that is more cost-effective and easier to maintain than leather, making it a popular choice for more functional and high-usage areas within an aircraft.
