The MP-81´s structure is composed of two fiberglass shells, welded together to create a single, rigid element. The solid wood feet are attached to the structure by screw nuts that are previously welded to the structure. The back feet can be assembled into two different positions, to create two versions: with or without the headrest, which is separated from the body. The foot assembly in the version with the headrest inclines the chair backwards to create a more laidback posture for the user.
