Right on top of the foam encasement is a 1” layer of memory foam.

This hold the coils in place, and it also serves as an insulator, separating the pocket coils from the hourglass coils beneath and the memory foam above, as well as smoothing out the feel of the coils. The entire pocket coil unit is wrapped in the foam encasement edge support – all 4 sides, the top, and the bottom. This is the oldest kind of coil used in innerspring mattresses. The outer rows and the ends of the inner rows are tied to upper and lower perimeter rods, which also serve as edge support. They are tied to each other with spiral wires running the length of each row. Constructionīonnell coils have an hourglass shape.

Many of the online mattresses have only one firmness available, somewhere in the middle. In this respect, the pocketed coils add conformity to the hourglass shaped Bonnells.Īnother reason for Saatva’s success is the choice the customer has for the firmness level: Firm, Luxury Firm, and Plush. The pocket coils being only 4” high makes them borderline micro-coils (or mini-coils). The effect of this configuration appears to work like a pocket coil mattress and a high coil-count box spring, all within one cover. The reason Saatva has been successful with this model is the layer of 4” pocket coils above the 7” Bonnell unit.

By that time, most new innerspring mattresses had offset coils, pocket coils or continuous coils. Introduced in 2011, the Classic Luxury Innerspring has a Bonnell coil primary support unit. In side-by-side comparisons by Sleep Like the Dead, Saatva has much higher customer satisfaction overall than Restonic and Stearns & Foster ( STLD does not cover Campbell Mattress). Along with Saatva, three older manufacturers are named by GoodBed as having top brands of coil-on-coil mattresses: Restonic, Campbell Mattress, and Stearns & Foster. It has a coil-on-coil construction, and this is why it is the mattress that the new WinkBed is compared to by reviewers. Saatva ’s memory foam mattress, Loom & Leaf, is better known, but their Classic Luxury Innerspring is still their signature model.
