Theres only one Super Pocketed Coil® spring
An innovation developed by Simmons, Pocketed Coil® springs are the secret to undisturbed sleep. Unlike the wire-tied springs in ordinary mattresses, Pocketed Coil® springs are not joined at the top or the bottom.

Instead, high carbon steel springs are pre-compressed and placed in durable, non-allergenic fabric encasements.

This allows the Super Pocketed Coil® springs to adjust individually to the weight and contour of your body. Since adjacent springs aren’t tied together, there’s no chain reaction of movement when you turn or move during the night.
