Excellent Support: The pocket coil spring system provides targeted support by conforming to the curves of your body, while the tight top provides added support to prevent sagging. Minimal Motion Transfer: The individual pocket coils work independently of each other, which helps to minimize motion transfer across the bed. This is especially beneficial for couples who may be easily disturbed by movement during sleep. Cooling Properties: Pocket coil spring mattresses allow for increased air circulation, which can help regulate your body temperature and keep you cool throughout the night.
