Serta iSeries NXG Hybrid 3500
The Details
The 3500 is Serta's premium tier — top of the iSeries NXG Hybrid line short of the flagship 4500. Higher pocketed coil count for finer-grained support, premium CoolFeel™ cover, hand-finished top. This is where the Serta mattress starts feeling really nice. Choose your feel — Firm for back/stomach sleepers and bigger frames, or Medium for the versatile sweet spot most sleepers prefer.
Best for: Sleepers ready to invest in a 10-year mattress, anyone who's owned cheaper hybrids and wants the real thing, hot sleepers who need cooling, couples in split-king configurations (Split Head Queen + King available).
Comfort options: Firm or Medium.
Sizes: Twin XL, Full, Queen, Split Head Queen, King, Split Head King, Cal King.
As low as $56/month with our 48-month Synchrony financing.
