Description

Firm comfort. Cooling relief. Reliable support.

The Serta iSeries NXG 1500 All-Foam Luxury Firm mattress is designed for sleepers who prefer a supportive, stable sleep surface with minimal sink. Its luxury firm feel helps keep the body properly aligned by preventing the hips and midsection from sinking too deeply into the mattress—an essential benefit for back and stomach sleepers. This balanced support promotes healthy spinal alignment while still offering gentle contouring to relieve pressure at key contact points.

Advanced cooling features deliver immediate surface cooling and help regulate temperature throughout the night, while high-density foam layers provide consistent support across the mattress. The all-foam construction absorbs motion to reduce sleep disturbances, creating a quiet, uninterrupted sleep environment. The result is a firm yet comfortable mattress that delivers reliable support, cooling comfort, and long-lasting performance.

Best for back and stomach sleepers who need stable, firm support to maintain proper spinal alignment, as well as anyone who prefers a firmer, more supportive sleep feel.
