The Kirchner series (Kirchner Super Pillow Top, Kirchner Plush and Kirchner Firm) is the second group of FreeFlex innerspring mattresses in Serta's 2015 Perfect Sleeper Collection. The other group consists of the three Lenmore models (Lenmore Super Pillow Top, Lenmore Plush, and Lenmore Firm). The Kirchner mattresses are not as high as the Lenmore ones. The Super Pillow Top is 10", and the Firm and Plush are 9½" high.
Like the Lenmore models, the Kirchner models feature the Custom Support Flex Innerspring, Cool Twist Gel Memory Foam, and Total Edge Foam Encasement. They also share a quilted stretch knit cover with FireBlocker Fiber, Pillo-Fill fibers and Serta's quilting foam.
The Flex 704 Innerspring consists of continuous coils free at the top. The free tops respond independently to conform to body contours. Like pocket coils, they reduce pressure on shoulders and hips, support the lumbar, and minimize partner disturbance.
Cool Twist is memory foam infused with liquid gel (in contrast to Cool Action's MicroSupport gel beads). The gel is to make the memory foam more supportive while still conforming. At the same time, gel is to keep the memory foam cool. The Cool Twist is open-cell foam to let air filter through.
It is in the quilting foams that the Kirchner Firm differs from the Kirchner Plush. In the Firm, it is Serta Support Foam. In the Plush it is Serta PillowSoft Foam.
The Kirchner Super Pillowtop has PillowSoft in the quilting. It also adds a layer of Comfort XD Foam in the pillow top. The Comfort XD is billed as "soft yet supportive." The intent is to make this model even softer than the Plush model.
The Perfect Sleeper Kirchner models are offered for sale with any of three foundations. First is Serta's advanced-design box spring, the StabL Base Foundation. This has V-shaped supports instead of the traditional coils.
All Perfect Sleeper Kirchner mattresses are warrantied by Serta for 10 years, non-prorated.
