The Sealy® Posturepedic 800 Jaxon 11.5” Tight Top Mattress delivers targeted support, cooling comfort, and exceptional durability—all at a value that makes it one of the strongest performers in the Posturepedic® lineup. Designed with Posture Touch® Individually Wrapped Pocket Coils, Jaxon provides reinforced support in the center third of the mattress, where 50% of your body weight rests. This reduces motion transfer and ensures proper spinal alignment night after night. A tight top firm surface, cooling MoistureProtect™ quilting, and CleanProtect™ antimicrobial fabric work together to keep the sleep surface fresh, dry, and comfortable. Added to that, SealySupport™ Gel HD Foam provides responsive cushioning and consistent support across the entire mattress. Ideal for back and stomach sleepers—or anyone who prefers a firm, supportive feel with modern pressure-relieving components.
