What are the common sizes of RV seats？

The size of common RV seats can vary depending on the vehicle model, design, and usage. However, I can provide some common size ranges as references:

Single seat:

Width: usually not less than 380mm to meet the hip support needs of the general population.

Depth: Determined based on the horizontal length of the thighs in human sitting posture, the average horizontal length of the thighs in Chinese human sitting posture is 445mm for males and 425mm for females. Therefore, it is generally more appropriate to control the sitting depth between 380-420mm.

Seats with armrests:

Seat width: usually not less than 460mm to ensure sufficient support space.

The distance inside the armrest: This dimension is usually determined based on the shoulder width of the human body plus an appropriate margin.

Sofa chairs:

Seat width: The seat width of a single person sofa chair is usually between 450-480mm.

Full package sofa: The seat width may be larger, usually between 500-600mm.

It should be noted that these dimensions are for reference only, and the actual size of RV seats may vary depending on the manufacturer, model, and design concept. When choosing RV seats, in addition to considering size, attention should also be paid to their comfort, durability, functionality, and compliance with safety standards.

If you have a specific RV model or brand, it is recommended to directly consult the official information of that model or contact the manufacturer to obtain the most accurate seat size information.
