<p>The one piece matters has a sprung core section, and is designed for orthopaedic use. Stresses in the heaviest parts of the body may be relieved by a spring system in the interior with regions of increased stiffiness, and bands of extra reinforcement. The springs (1) are uniformly distributed throughout the interior of the mattress. In the intermediate spaces between the springs (1) flexible cylindrical stiffener inserts providing extra pressure resistance are positioned. These profile bodies (2-5) can be manufactured from a variety of synthetic materials such as plastic, foam rubber, or synthetic rubber.</p> |
