Only in conjunction with a high quality slatted frame the mattress can provide a comfortable sleep. The slatted frames are available in different price ranges as well as in various designs. Inexpensive slatted frames For example, they consist of simple slats that are slightly curved upwards and give way under pressure. However, these slatted frames can not be adjusted. On the other hand, more comfort is provided by the use of spring wood frames with flexibly mounted strips. Versions with shoulder and center zone reinforcement are available with these spring wood frames. This means that the middle lying zone offers stronger or additional slats. Such slats are especially suitable in humans with a little more weight. But especially comfortable are slatted frames with a spring base with elastic wings or plates. The load-bearing elements of these slatted frames are made of modern plastic and can be moved in all directions. As a result, they offer a particularly large number of support points and ensure optimum adaptation to the shape of the body. Furthermore, many slatted frames offer mechanical adjustability of the head and foot sections. Some models even come with an electric adjustment and can be easily brought by remote control in the optimum position.
