Part gel memory foam, part advanced innerspring
Are you interested in the benefits of a memory foam mattress, but prefer the comfort and support of a traditional innerspring? Our iSeries hybrid mattresses combine the same memory foam innovations found in our all-foam iComfort® Sleep System with the support of an advanced innerspring. This unique construction works to provide cooling comfort at the sleep surface with deep individual support for each sleep partner.
Every iSeries hybrid mattress features Cool Action™ Dual Effects Gel Memory Foam – Serta´s latest breakthrough in gel memory foam technology. This is the worldâ€™s first material to combine both our original MicroSupport® gel and our MicroCool+™ gel in a material with up to 25% more total gel than our original formula. Plus, we have upgraded our exclusive individually wrapped coil support system by adding even more Duet™ Coils, which help properly balance comfort and support across the mattress regardless of body type.
Outstanding Pressure Relief
Too much pressure build-up while you sleep can cause disruptive tossing and turning. Serta’s Cool Action™ Dual Effects® material is uniquely designed to help reduce average body pressure while you sleep, which can help reduce tossing and turning for a deeper and more restful sleep.
Support Where You Need it Most
Serta’s Cool Action™ Dual Effects® material works to uniquely support your body where it needs it most. Millions of MicroSupport® gel beads gather under the areas of your body that need extra support. Meanwhile, each Duet® Coil in the advanced innerspring is engineered so that the exterior coil provides an initial soft and luxurious feeling, responding to weight and body movement instantly. Plus, the interior coils, once engaged with body weight, react with increasing firmness to provide the essential support needed for correct postural alignment. With the right support, your muscles can relax and rejuvenate so you can wake up feeling refreshed.
Enhanced Cooling Comfort
Heat build-up during the night can cause uncomfortable and restless sleep. Serta’s Cool Action™ Dual Effects® material combines an open cell structure with our exclusive MicroCool+ gel to significantly increase airflow and the ability to dissipate heat. Together with the natural airflow design of an innerspring support system, these properties help whisk heat away from the body.
Serta Exclusive Technology
Our revolutionary Cool Action™ Gel Memory Foam material inspired an entirely new category of sleep systems. This material was developed after years of careful study and refinement of existing memory foam products, including the original NASA-inspired memory foam technology. We then improved this with our Cool Action™ Dual Effects® material, which combines our original MicroSupport® gel with our breakthrough MicroCool+ gel in a foam with up to 25% more gel than our original Cool Action™ material. Our material represents a new science in memory foam, re-engineered from the bottom up for excellent comfort, support, temperature regulation, and durability. Plus, our Duet® Coil Support System is exclusive to Serta and features a posturized design, with nearly two-thirds of the Duet® Coils concentrated in the center third of the innerspring.
Comfort that Lasts
Serta’s Cool Action™ Dual Effects® material has been engineered and extensively tested to deliver exceptional comfort for years.
