A recliner is an armchair or sofa that reclines when the occupant lowers the chair's back and raises its front.^[1][2] It has a backrest that can be tilted back, and often a footrest that may be extended by means of a lever on the side of the chair, or may extend automatically when the back is reclined.

A recliner is also known as a reclining chair, lounger and an armchair.^[1]

Modern recliners often feature an adjustable headrest, lumbar support and an independent footstool that adjusts with the weight and angle of the user's legs to maximize comfort.^[3] Additional features include heat, massage and vibration. Some models are wheelchair accessible.

Recliners can also accommodate a near supine position for sleeping (making them multifunctional furniture), and are common in airplanes and trains, as well as in homes.
