Key Performance Layers
Quilted ComfortKnit Top: This mattress features a high-quality knitted exterior meticulously quilted over a dense padding layer. It provides a soft, flexible touch that breathes with your body, while the firm quilting ensures you remain supported on the surface rather than sinking deep into the layers.
Infused Gel Cooling Foam: Designed specifically to combat heat retention, this gel-infused layer acts as a thermal regulator. It wicks away excess body heat to provide a refreshingly cool environment for a deeper, more comfortable sleep.
ComfortFirm™ Core Layer: The heart of the Sapphire’s "balanced firm" profile. This resilient foam is engineered to keep your spine in a neutral position while gently alleviating pressure points, giving you the stiffness of a firm mattress with the touch of comfort you need.
390 Essential Spring with 360° Border: A traditional steel innerspring unit provides that familiar, responsive support. It is completely surrounded by a 360-degree foam encasement, which reinforces the mattress perimeter to prevent roll-off and increase the overall life of the bed.
High-Density Support Base: This heavy-duty foam foundation serves as the mattress's anchor. It guarantees that weight is spread out uniformly across the coils, maintaining the bed’s shape and ensuring long-lasting durability.
