Wire-Tied Coil units are durable and responsive. Because they are many coils linked together to make a single piece. Therefore, in a wire-tied coil system, every spring is supported by the adjacent coils.That helps maximize comfort and durability. These mattresses give proper support for all types of people.
A medium gauge coil (13-gauge) allows for gentle comfort. It still maintains support and durability. A shortcoming of these mattresses is lateral transfer of motion. Motion throughout the mattress results in one moving partner waking the other. However, this can be addressed by running the strands of connecting wire between coils from head to toe rather than side to side. That keeps the movement on one side of the bed. It can also be reduced by running foam in between coils to dampen the jiggle.
