Sleepyhead’s ActiveSense spring with Active Coil technology offers all of the benefits of a traditional pocket spring with an increased level of comfort and support. An intelligent two-stage coil detects and deflects pressure; the outer, wider coils detect movement and provide added comfort, while the inner tighter coil deflects pressure, offering additional support.
