The invention relates to the technical field of universal aviation and discloses a liftable aviation seat with high comfortableness. The liftable aviation seat includes a damping plate, a side plate is fixedly connected to the top of the damping plate, a spring base is fixedly connected to the portion, in front of the side plate, of the top of the damping plate, an air leg is fixedly connected tothe top of the spring base, a damping spring is fixedly connected to the portion, behind the air leg, of the top of the spring base, and a top plate is fixedly connected to the top of the damping spring. According to the liftable aviation seat with high comfortableness, through the damping plate, the air leg and the damping spring, a vibration force generated by equipment of a cabin on the aviation seat which is in linkage with the equipment is effectively dispersed, interference caused by vibration to a passenger who needs a quiet environment for a rest is reduced, and convenience is providedfor the passenger to have a rest during a trip; the vibration can be alleviated through elastic energy of a memory cotton cushion, a certain protection effect is achieved on the body of the passenger, and meanwhile, by dispersing pressure to relieve fatigue of the passenger after the passenger sits for a long time, the comfortableness during the trip is improved.
