Perfect Day iSeries Jubilance

Jubilance is a mid-level model in the Perfect Day iSeries collection by Serta. It features Serta's iSeries® Technology, which combines Cool Action™ gel memory foam and Duet Coil individually wrapped coil-in-coil system. Serta cites the benefits of adding to this their Motion Perfect® Adjustable Foundation, so the user can customize the support and comfort of this mattress. The Jubilance has a mid-range comfort level, 5.5 on a scale of 10.

There are two 1" layers of Cool Action™ gel memory foam in the Jubilance. Cool Action is a memory foam which is infused with Serta's MicroSupport™ gel, beads of micro-encapsulated gel. This gel both contributes to the support characteristics of the memory foam and cools it. Visco-elastic memory foam is very comformable, which is why it cradles a sleeper. Gel makes it more supportive, improving pressure point relief. Gel also is a heat sink, drawing heat away from the sleeping surface.

In addition to the Cool Action™ gel memory foam, Perfect Day iSeries Jubilance also has a 2" layer of Serta's KoolComfort memory foam. Developed before gel memory foam, KoolComfort has an open-cell structure, allowing air to flow through it to cool it off. This was an answer to the tendency of memory foam to build up heat.

The Duet Coil individually wrapped coil-in-coil system in Jubilance mattresses is an array of pocket-wrapped dual coils. The advantage of pocket coils is the independent response of the individual coils to weight placed directly on them. This allows the innerspring assembly to conform faithfully to the shape and weight of the sleeper's body. These are also 2-in-1 coils, a coil within a coil. The taller outer coil has the initial response, to give a feeling of soft, cushioning support. The inner coil, when it is reached, increases resistance to provide deep support. The coil count in a queen-sized Jubilance is 924.

BestEdge foam encasement provides both innerspring perimeter support and sleeping surface edge support in the Serta Perfect Day iSeries Jubilance mattress. It keeps the Duet Coils in place and upright. It also makes the entire sleeping surface stable and usable, even for sitting on the edge.

The quilted cover of the Jubilance mattress is certified for fire safety, meeting federal standards. It is what Serta calls Continuous Comfort, because it allows the sleeper to experience the comfort of the Cool Action™ gel memory foam.

Serta encourages the customer to pair the Perfect Day iSeries Jubilance with its Motion Perfect® Adjustable Foundation, but matching box springs are also available in a choice of Standard (9") or Low Profile (5.25") heights.

Serta offers a 120 sleep trial period for the Jubilance and a 25 year warranty against manufacturer's defects, with the first fifteen years non-prorated and the last ten years prorated.
