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 more even weight distribution across the mattress.
The additional support zones target added support at your lumbar and thighs through a firmer coil gauge.
