Are there seats on the Airbus A321 that do not recline?

Some airlines do install non-reclining seats on their Airbus A321 aircraft. Some airlines install these seats on most or all rows of the aircraft, while other airlines only use non-reclining seats in areas such as exit rows or near bulkheads.

An example of an airline using non-reclining seats on the Airbus A321 is Monarch Airways, a carrier that began installing non-reclining seats on its Airbus A321 fleet in 2014, according to travel website BoardingArea. These seats are referred to as pre-reclined by Monarch Airways in promotional materials, and the airline claims that these seats actually offer more legroom and space than traditional reclining seats.
