Product Description

To begin with, the 13.5-inch ultra plush hybrid mattress greets you with a CoolFeel™ stretch-knit cover that feels cool and airy from the first touch. Next, layers of NXG Next Generation Memory Foam intertwined with Cool Action Gel Memory Foam melt around your curves, creating a cloud-like pressure relief many side sleepers call “hotel-suite soft.”

Because these foams float above a precision Duet Coil-in-Coil Support System, you still enjoy targeted spinal support for side sleepers that keeps hips lifted while shoulders nestle deeper. Individually wrapped inner and outer springs dampen energy, delivering advanced motion isolation technology so partners remain undisturbed. 

A high-density foam encasement protects every edge, giving the mattress a sturdy perimeter and a luxurious 13.5-inch profile that fits deep-pocket sheets. Finally, you can Buy Serta iSeries NXG 4500 online today through Cloudy Mattress, secure free USA delivery, flexible Affirm financing, and rest easy under a 120-night trial and 10-year warranty while the sale lasts.
