How to Choose the Right Serta Mattress

Serta® names its coil systems for how the support layer is organised, which makes the name the most useful thing on the label. Where a name says zoned, the coil unit is divided along its length into sections set to different resistances, so the middle of the bed can hold your hips up while the head and foot sections stay softer under shoulders and calves. The 1000 and 950 Series 3-Zoned Coil System and the 1050 3-Zoned Coil System split the surface three ways, while the 1250 and 2550 Series 5 ZoneActive Pocket Coil System divides it into five, giving shorter, more gradual steps between firm and soft. Serta also builds on the 800, 825 and 850 Edition Custom Support® Coil Systems.

Two other pieces of engineering matter when comparing models. Best Edge® Foam Encasement is a rigid foam frame built around the coil unit, and Serta specifies it model by model rather than as part of any one coil system, so check the model you are looking at. It stops the perimeter collapsing when you sit on it and makes the outer few inches usable for sleeping rather than a slope you roll away from. In the comfort layers, gel memory foam has a gel component mixed through the foam, which raises the thermal mass so the surface takes longer to reach body temperature; airflow, an open cell structure and the cover do the sustained work. Moulded memory foam is poured into a shaped mould so its contours are formed rather than cut. You can also explore the Serta iComfort collection. Comfort choices run across Extra Firm, Firm, Medium and Plush.
