The present invention relates to a different hardness seat for a vehicle. More specifically, the different hardness seat for a vehicle comprises: a main body seat formed in a seat shape of a vehicle and having an insertion groove at a portion at which the back of a passenger is supported when the passenger is seated a shock absorbing seat formed to be attached or detached from the insertion groove of the support seat that is made of a material with a hardness lower than when a passenger is supported, and having an uneven portion having an egg carton shape to form an air layer on the front surface a friction seat made of a material having the same hardness as that of the shock absorbing seat and formed of a synthetic rein foam body, which has a seat shape, adhering or fused to the uneven part of the shock absorbing seat and to absorb a load applied to the shock absorbing seat and transmit the load to the shock absorbing seat a filter seat adhering to the uneven part of the shock absorbing seat and a rear surface of the friction seat by emerging a binder in a felt made of glass fiber and a perfume container containing liquid perfume between the friction seat and the filter seat and discharging the scent of the perfume liquid to the outside. The different hardness seat for a vehicle can increase comfort of a passenger by having the shock absorbing seat and the friction seat with which the passenger is in contact and which have a hardness lower than that of the main seat, create an efficient shock absorbing effect by absorbing a load generated by a passenger to the friction seat, absorbing and dispersing the remaining shock to the uneven part formed on the shock absorbing seat, and minimizing vibration transmitted to the support seat, and can provide a comfortable indoor environment by allowing the filter seat and the perfume seat to sterilize harmful materials, filter various harmful materials and fine dusts from the outside, and filter the air in a vehicle.COPYRIGHT K
