Overview
Stearns and Foster Estate Firm Mattress 14.5" Twin XL
Built for back pain relief without giving up the feel of a handcrafted luxury mattress
IntelliCoil® innersprings keep your spine lifted all night
TEMPUR-Indulge™ Memory Foam takes the pressure off hips and lumbar
PrecisionEdge™ border holds the edge firm so every inch is usable
TENCEL® cover wicks moisture and sleeps cooler than standard fabric
The Stearns and Foster Estate Firm Mattress 14.5" is a luxury innerspring mattress built for the back sleeper who wants genuine spinal support without sleeping on a slab. This is a firm mattress for back pain relief that earns that claim through real construction: coil-within-coil IntelliCoil® innersprings respond to your body weight rather than simply pushing back against it, and a comfort layer of TEMPUR-Indulge™ Memory Foam, developed exclusively by the scientists at Tempur-Pedic® for Stearns and Foster, wraps the pressure points your lower back and hips send into the surface. The handcrafted finish is not decorative: every mattress is hand-sewn and hand-signed by certified master craftsmen, a level of detail you feel in how the mattress holds its shape over years, not just weeks. Stop by any Mancini's Sleepworld location and our sleep specialists will put this next to every competing option so you can feel the difference for yourself.
COMFORT AND FEEL: A firm feel with memory foam cushioning that absorbs pressure without letting the lumbar sink.
SIZE: This Twin XL sized mattress is sized for taller single sleepers, college dorm setups, or adults who stretch out and need every inch of that extra length.
BEST SLEEP MATCH: Back sleepers and stomach sleepers who want a firm mattress for back sleepers that holds the spine level while the memory foam layer softens the surface just enough to stop hip pressure from waking them up.
BEST FOR: Ideal for sleepers who want firm lumbar support, deal with lower back tension in the morning, or run warm and need a cooler sleeping surface.
CONSTRUCTION SPECIFICATIONS: The IntelliCoil® system uses a coil-within-coil design that activates progressively under pressure, firmer where you push harder, softer where you don't. TEMPUR-Indulge™ Memory Foam sits above the coils and shapes to your body contour for pressure relief. The AirVent System pulls warm air through and out of the mattress. PrecisionEdge™ reinforces the perimeter so the surface stays stable to the very edge. The TENCEL® cover wicks moisture and keeps the sleep surface feeling fresh.
SETUP AND COMPATIBILITY: Delivered flat with professional in-home setup available. Compatible with adjustable bases, platform frames, and box springs. No tools needed for setup.
NOT A FIT FOR: Side sleepers who need deep hip and shoulder contouring may find the firm feel too resistant. Not the right call for anyone who prefers a plush or pillow-top surface.
