Part gel memory foam, part advanced innerspring. Meet the iSeries® Hybrid Sleep System by Serta.

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 world’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.

Customize your comfort and support.

We offer a variety of iSeries mattresses ranging in feel from luxuriously plush to extra-firm, so you can find an iSeries mattress to meet your specific needs. Plus, every iSeries mattress is compatible with a Serta® adjustable foundation so you can be comfortable and supported whether you are sleeping, watching television, reading or just relaxing in bed.

What Makes iSeries Technology Different?

All foam is not created equal. iSeries features or breakthrough Cool Action Dual Effects® Gel Memory Foam. This is the world's first material to infuse both our MicroSupport® and MicroCool+ gels into premium memory foam for an extremely comfortable and supportive sleep surface, while helping to reduce the heat build-up that can be associated with memory foam mattresses.

  • Outstanding Pressure Relief
  • Support Where You Need it Most
  • Enhanced Cooling Comfort

Experience the Benefits of an Adjustable Foundation

  • Customized Comfort & Support

    Adjust the head and/or foot of your mattress to find the perfect position. Plus, select models have advanced features such as variable massage options and pre-set positions!

  • Ease back, neck & shoulder pain

    Elevating the head and foot of the mattress can help alleviate pressure on your back, neck and shoulders.

  • Improve Circulation

    Elevating your head and feet can help increase blood flow, which can help reduce tossing and turning.

  • Reduce Snoring

    With an adjustable foundation, you can adjust the position of your head to help open up airways and help reduce snoring.

    While many have told us they experience these benefits from an adjustable foundation, these claims have not been validated by medical testing. Your bed’s foundation is not a medical device. Please consult your doctor if you suffer from any of these medical conditions.
