High-speed rail first-class seats are not business seats. The main differences between first-class and business class seats on the high-speed rail are as follows. 1. Business seats can be adjusted arbitrarily between 90 degrees and 180 degrees in different spaces. They are driven by servo motors and can lie flat. First-class seats are more spacious than second-class seats, with 4 seats in a row. There are five seats in a row in second class. The price of a business seat ticket is approximately 1.8 times that of a first class seat. 2. Different service facilities Business seats are equipped with service spare parts such as cooling blankets, seat cushions, goggles, small towels, slippers, shoe covers, and headphones. Free drinks, breakfast, dinner, snacks and newspapers. There is a TV and table in the left and right armrests of the seat, and a reading light in the backrest. At the same time, flight attendants will provide more thoughtful services to VIPs. There is a small table on the armrest on the right side of the first-class seat. When the small table is not needed, it can be folded to create more space. The biggest benefit is actually that there is a button on the armrest button to adjust the volume of the headphones. Passengers can plug their headphones into the armrest jack and enjoy classical, pop or traditional music played randomly in the car to relieve travel fatigue. 3. The environment is different. There is basically no noisy external interference in the commercial vehicle, and the noise will not affect the work or rest of the passengers. This car has a larger viewing window. There is a dedicated microwave oven at one end of the commercial vehicle and a dedicated bathroom next to it. There are no first class seats left. The high-speed rail seats are introduced as follows: There are three types of high-speed rail seats: second-class seats, first-class seats and business seats. Second-class seats have 5 seats in each row, with a "2+3" layout, an aisle in the middle, and blue velvet sofa seats. They are the cheapest and most economical. There are 4 seats in each row of first-class seats, in a "2+2" layout, with an aisle in the middle and red velvet sofa seats. Compared with second-class seats, first-class seats are wider and the distance between the front and rear seats is greater. High-speed rail business seats can realize one-click conversion from sitting to semi-lying or lying down, stepless adjustment, and manual reset in case of power outage; when the seat is completely tilted down, it can become a sleeper. There are only four seats in each row of the first-class carriage, so the seats are more comfortable and spacious, and the inclination of the seats can be adjusted. There is also a small pillow at the neck, giving you more room to stretch your feet.
