What are the benefits of 5-zoned support?
The goal of the 5-zone support, which is found only in 3000 Hybrid Medium and Plush models, is to help align your spine while providing evenness of pressure relief for a supportive night’s sleep. 
With our 5 zoned support, we’ve increased those zones to provide total targeted body support for a more even weight distribution across the mattress. The additional support zones target added support at your lumbar and thighs through a firmer coil gauge.
