To begin with, the Serta iSeries NXG 4500 Ultra Plush Mattress welcomes you with a CoolFeel™ cover that feels cool at first touch. Next, layers of NXG Next Generation Memory Foam infused with gel cradle every curve, delivering a cloud-like soft sleep surface that side-sleepers rank among the softest 13.5-inch beds available.
Beneath this deep plush, a transitional comfort layer settles the body onto a Duet coil-in-coil support system, providing targeted spinal alignment support and lively push-back that keeps hips level even in ultra-soft comfort.
Individually wrapped springs flex independently, creating advanced motion isolation for couples so you feel less movement when your partner turns. High-density foam encasement reinforces every edge, expanding usable surface and adding durability.
Finally, you can buy Serta iSeries NXG 4500 online through Cloudy Mattress, enjoy free shipping in the USA, fast delivery, and easy Affirm financing—all while the Memorial sale knocks $1,500 off this luxury profile.
