  • EverCool Fuze Gel Foam: This cooling gel-infused foam layer further provides temperature control by increasing airflow and dissipating heat.

Support & Motion Isolation

This mattress's 1025 individually wrapped coils combined with quality layers of body conforming memory foam make the Serta iSeries Hybrid 1000 great at providing motion isolation.

Like this bed's motion isolation performance, the Serta iSeries Hybrid 1000 performs exceptionally at edge support. The border of this mattress is encased in an extra deep high density foam rail which reinforces its edges. This means that more surface area can be used, and potential roll-off and sagging are greatly reduced.
