Stearns & Foster Lux Hybrid Firm: memory foam on top, real coils underneath
If you have wanted the deep, body-hugging feel of a memory-foam bed but worried it would swallow you, the Lux Hybrid Firm is that feel built firm. It leads with TEMPUR-Indulge™ memory foam, the pressure-relieving foam engineered by the sleep experts at Tempur-Pedic, then lets the IntelliFlex™ hybrid coils carry the support. The result reads firm, an 8 out of 10 at 14 inches, but it never feels like a hard board. This is a back and stomach sleeper's bed first.
Why a hybrid at the Lux level
People who love a contouring memory-foam surface usually miss two things: the responsiveness and the airflow of coils. The Lux Hybrid is built for that sleeper. The foam gives the cradle on top, and the hybrid coils underneath add the lift, the cooler airflow, and a stronger edge than all-foam can manage. You keep the memory-foam feel and lose the sink.
What you notice in the first few minutes
Lie down and the foam meets you first, a soft top layer that conforms to your back and hips. Then the coils answer underneath, and that is where the firm reading comes from. At an 8 out of 10 it holds you up and keeps your spine in line while the foam eases the spots that usually ache by morning. Roll over and the coils help you move instead of holding you in place.
The IntelliFlex™ difference
IntelliFlex is Stearns & Foster's hybrid support system: a coil unit engineered to respond point by point beneath the comfort foam, so the bed supports your spine precisely while the foam relieves your pressure points. Where the brand's coil-led Estate and Lux Estate beds are built on the patented IntelliCoil coil-within-coil system and let you feel the coil first, the Lux Hybrid puts the foam feel first and lets the coils do the supporting.
Craftsmanship you feel
A cooling cover keeps the memory-foam surface from sleeping warm, the reinforced edge keeps support nearly wall to wall, and Stearns & Foster builds it by hand to a Lux-level standard. The foams are CertiPUR-US certified, and the bed is backed by a 10-year limited warranty against manufacturing defects, honored in full because Mattress Overstock is an authorized dealer.
Who it suits, and who it doesn't
On your back, the firm hybrid support keeps you level while the memory-foam surface still relieves pressure. On your stomach, the firmness keeps your hips from dropping out of line, and the coils add enough life that it never feels dead-flat. Memory-foam fans who want firm get the foam feel without the sink. Couples share it easily: the reinforced edge keeps the whole surface usable, and the wrapped coils keep one person's movement from waking the other. The honest anti-fit is side sleepers. At an 8 out of 10 the shoulder and hip have nowhere to give, so if you sleep on your side, try the Lux Hybrid Soft on the same floor first.
Where it sits in the lineup
The Lux Hybrid comes in three feels (Firm, Medium, and Soft), so you can dial in firmness without leaving the hybrid lane. All three share the same IntelliFlex hybrid build, so you are choosing surface feel, not a different bed underneath. For the brand's coil-led builds, compare the Estate and Lux Estate tiers in the full Stearns & Foster lineup, which lead with the IntelliCoil coil-within-coil system rather than foam.
Ten minutes beats ten reviews
Memory-foam-on-coils is a specific feel, and you will know in about a minute whether it is yours. Lie on the Lux Hybrid Firm this week at any of the five Mattress Overstock showrooms in Kentucky (Lexington, Richmond, Georgetown, London, and Somerset), with its Medium and Soft siblings right beside it, no appointment needed. The team is rated about 4.7 stars across 535 Google reviews and is paid the same no matter which brand you choose, so the guidance is about your back, not a quota. The 90-night trial holds when you buy from a local dealer, and delivery, setup, and old-mattress removal are free across Kentucky. Select your size to see the live price, or come feel it in person first.
What makes this mattress different
TEMPUR-Indulge™ Memory Foam on top
The deep, pressure-relieving cradle that defines the feel, the same memory foam engineered by the sleep experts at Tempur-Pedic.
IntelliFlex™ Hybrid Support
Stearns & Foster's hybrid coil system: point-by-point support and airflow under the comfort foam, so the firm reading comes from real coils, not a foam slab.
Firm Feel, 8 out of 10
Tuned to an 8 out of 10 on the IntelliFlex hybrid core: firm, spine-level support with a hybrid's give, never a dead-flat board.
Cooler Than All-Foam
The hybrid coil core moves air the way a solid foam base can't, and a cooling cover keeps the memory-foam surface from sleeping warm.
Reinforced Edge
Support that runs nearly wall to wall, so you can sit or sleep to the edge without the roll-off all-foam beds are known for.
Handcrafted by Stearns & Foster
Built by hand to a Lux-level standard: a hybrid made with the brand's flagship care, CertiPUR-US certified foams inside.
Try It in Kentucky, Not in a Box
On the floor at all five Mattress Overstock showrooms next to its Medium and Soft siblings, so ten real minutes settles the feel.
90-Night Trial · 10-Year Warranty
Sleep on it for 90 nights, backed by Stearns & Foster's 10-year limited warranty, honored when you buy from an authorized dealer.
Lux Hybrid Firm, layer by layer
The Lux Hybrid leads with foam over a responsive coil, which is what makes it feel like memory foam but support like a hybrid:
- Cooling cover. Keeps the memory-foam surface from sleeping warm and gives the top its first soft touch.
- TEMPUR-Indulge™ memory foam. The deep, pressure-relieving cradle that defines the feel, engineered by the sleep experts at Tempur-Pedic to ease the shoulders, hips, and lower back.
- IntelliFlex™ hybrid support system. A coil unit that responds point by point under the foam: this is where the firm 8-out-of-10 reading, the lift, and the airflow come from.
- Reinforced edge and base. Nearly wall-to-wall support and a stable foundation, so the whole surface stays usable.
14 inches tall, firm (8 out of 10), backed by the 90-night trial and Stearns & Foster's 10-year limited warranty. Where the coil-led Estate and Lux Estate are built on the patented IntelliCoil coil-within-coil system, the Lux Hybrid puts the foam feel first and lets the IntelliFlex coils carry the support.
What's inside a Stearns & Foster
Hand-built around IntelliCoil® (a precision coil inside a coil) under layers of cushioning foam and a tailored quilted cover.
Built for back and stomach sleepers who want firm, not a hard board
Back sleepers: the best match. Firm hybrid support keeps your spine level while the TEMPUR-Indulge surface still relieves pressure at the shoulders and hips.
Stomach sleepers: the firmness keeps your hips from sinking out of line, and the coils add enough life that it never feels flat or dead.
Memory-foam fans who want firm: you get the foam feel you love without the all-foam sink, because real coils carry the weight underneath.
Hot sleepers: a fair fit. The hybrid core sleeps cooler than an all-foam bed of the same feel, and the cooling cover helps the surface, though airflow does more of the work than the cover.
Couples: the reinforced edge keeps the whole surface usable and the individually wrapped coils keep one person's movement from waking the other.
Side sleepers: the honest anti-fit. At 8 out of 10, the shoulder and hip have nowhere to sink, so most side sleepers wake up sore. Try the Lux Hybrid Soft or the Medium on the same floor instead.

Frequently asked questions
How firm is the Lux Hybrid Firm?
About 8 out of 10, where 10 is the firmest. It is firm, spine-level support with a hybrid's responsiveness, read off the IntelliFlex hybrid core rather than a stiff foam slab. You feel the soft memory foam first, then the coils hold you up.
What is the IntelliFlex™ hybrid support system?
Stearns & Foster's hybrid coil system: a responsive coil unit under the comfort foam that supports your spine point by point while adding airflow and a firmer edge than all-foam can manage. It is what makes a foam-feel bed support like a hybrid.
How is the Lux Hybrid different from the Estate or Lux Estate?
The Estate and Lux Estate lead with the patented IntelliCoil coil-within-coil system, so you feel the coil first. The Lux Hybrid leads with TEMPUR-Indulge memory-foam feel over an IntelliFlex hybrid core. Choose the Lux Hybrid if you love memory foam but still want a hybrid's lift and cooling.
Which feel should I choose, Firm, Medium, or Soft?
Firm (8/10) suits back and stomach sleepers. Medium is the universal middle. Soft leans toward side sleepers. All three share the same IntelliFlex hybrid build underneath, so you are choosing surface feel, not a different bed. Feel them side by side on the showroom floor.
Does it sleep hot?
Cooler than an all-foam bed of the same feel. The hybrid coil core moves air, and a cooling cover keeps the memory-foam surface comfortable. If sleeping hot is your single biggest issue, a firmer all-coil hybrid will breathe a little more.
How tall is it, and will my sheets fit?
14 inches. Deep-pocket sheets rated for 14 inches or more sit best. It is worth measuring the height against your frame and any headboard before delivery.
Do I need a special foundation?
No. A sturdy platform, a close-slatted base, a solid foundation, or a compatible adjustable base all work with the hybrid. A traditional box spring is not the right base for it and can affect the feel and the warranty.
What is the warranty, and is it honored at Mattress Overstock?
Stearns & Foster's 10-year limited warranty against manufacturing defects, honored in full because Mattress Overstock is an authorized Stearns & Foster dealer, not a reseller.
What if it is not the right feel after I get it home?
You get a 90-night trial. If the feel is not right, exchange it for store credit toward any bed of equal or greater value (no cash refund, and no restocking-fee games). The honest move is to lie on it in the showroom first so it rarely comes to that.
Can I see it near me?
Yes. It is on the floor across the five Kentucky showrooms (Lexington on Nicholasville Road, Georgetown, Somerset, London, and Richmond), with its Medium and Soft siblings beside it for a side-by-side. Free local delivery, and the old mattress is hauled away.
