Bucket seat and bench seat

Rear bench seat for three adult passengers in a AMC Ambassador

A bucket seat is a separate seat with a contoured platform designed to accommodate one person, distinct from a bench seat that is a flat platform designed to seat up to three people. Individual bucket seats typically have rounded backs and may offer a variety of adjustments to fit different passengers.

Folding seats

Early touring cars featured folding auxiliary seats to offer additional passenger capacity.[1]

Some sedan models offer fold-down rear seats (e.g. Chevrolet Corvair), to gain cargo space when they are not occupied by passengers.

A fold-down front-passenger seat was a feature on the Chrysler PT Cruiser to fit longer longer items such as a 8-foot (2.4 m) ladder inside the vehicle.[2]

Ergonomy: lumbar and thigh support

The lumbar is the region of the spine between the diaphragm and the pelvis; it supports the most weight and is the most flexible. The adjustable lumbar mechanisms in seats allow the user to change the seat back shape in this region, to make it more comfortable and include adjustable lumbar cushion. Some seats are long enough to support full thigh and follow back curves.


The National Traffic and Motor Vehicle Safety Act enacted by the U.S. in 1966 established standards of strength for automobile seats. These included requirements for proper anchorage and construction of automobile vehicle seat assemblies.[3]

Anti-submarine seat

This kind of seat incorporates specially shaped panels in the forward edge of the seat cushion, reducing the tendency for the occupant to slide beneath the seatbelt in a severe frontal collision.[4]

Anti-submarine seating is a safety feature that may be more important for the front seats than the rear seats.[5]

Child seats

A child restraint system, also commonly referred to as a child safety seat or a car seat, is a restraint which is secured to the seat of an automobile equipped with safety harnesses or seat belts, to hold a child in the event of a crash.

  • The legal requirements for a child to sit up front is 5'0 and they must be more than 80 lbs.

Power seats

Some car seat systems are set up with a battery-powered automatic control to adjust how the seat sits in the car.

In suitably equipped cars, seats and mirrors can be adjusted using electric controls. Some vehicles let the driver(s) save the adjustments in memory (memory seat) for later recall, with the push of a button. Most systems allow users to store more than one set of adjustments. This allows multiple drivers to store their comfort settings, or a single driver to store several different occupant positions. Some vehicles associate memorized settings with a specifically numbered, remotely operated key fob, resetting a seat to the position associated with that fob when the vehicle is unlocked (e.g. key fob #1 sets seats to memory position #1, #2 to #2, etc.).


Car seat covers are accessories that protect the original seat upholstery from wear and add a custom look to a vehicle's interior. They can help to maintain the resale value of the vehicle and maximize the comfort of the driver and passengers.
