Stearns & Foster Lux Estate 13.5-inch Ultra Firm Innerspring Mattress
Features: Built with the IntelliCoil HD support system, a ventilated coil perimeter, and TEMPUR-Indulge memory foam for slight surface contouring.
Core Specifications & Design
Support System: It relies on IntelliCoil HD technology, which features a dual-stage coil design (an outer coil for adaptive comfort and an inner coil for deep, rigid support).
Comfort Layers: Unlike traditional brick-hard mattresses, it incorporates TEMPUR-Indulge Memory Foam. This specialty foam layer provides pinpoint pressure relief for your hips and shoulders while preserving the extra firm foundation.
Temperature Regulation: It features a moisture-wicking Tencel cover alongside lateral air vents and a highly ventilated coil border to actively channel heat away from your body.
Edge Support: Armed with a PrecisionEdge high-density coil border, the mattress ensures you can sit or sleep right on the edge without feeling like you are sliding off.
