Beautyrest® Harmony Lux™ Hybrid Ocean View Island Medium
Couldn't load pickup availability
The honest verdict: the Harmony Lux Hybrid is Beautyrest's premium line one step below Black, and for a lot of sleepers it is the value sweet spot. The Ocean View Island Medium is a true medium, about 5 out of 10, built on the Precision Support System with T2 Pocketed Coils, RightTemp Wave Foam made with cooling carbon fibers, and an InfiniCool Lux cool-to-the-touch surface. If you want genuine Beautyrest engineering and strong cooling without paying for the Black tier, this is the one to come feel.
What it is made of, and what that does for you
- Precision Support System with zoned T2 Pocketed Coils. Each coil is wrapped on its own. T2 means two wires twisted together before they are coiled, so they are stiffer than a single-wire coil (Beautyrest Black steps up to three-wire T3). Those firmer coils run down the center third of the bed, right under your hips, where most people sink first.
- RightTemp Wave Foam with carbon fibers. Carbon is a real heat conductor, and it is built into the foam to pull warmth off the surface. This is the line's cooling signature, not a marketing word.
- InfiniCool Lux phase-change cover plus ActiveResponse Memory Foam. The cover carries a phase-change finish that reads cool the instant you touch it, over responsive foam that relieves pressure without the slow-sinking memory-foam hug.
- BeautyEdge foam-encased edge. A firm foam perimeter wraps the coils, so the mattress holds its shape when you sit or sleep near the side instead of caving.
- A true medium on a 13.5-inch profile. The universal feel that works for back, side, and combination sleepers, on a tidy height worth measuring against your frame and deep-pocket sheets.
- CertiPUR-US foams, recycled cover, 10-year warranty. The comfort foams are CertiPUR-US certified, the cover knit uses recycled fibers with handles for rotating the bed, and Beautyrest backs it for ten years.
What you notice in the first few minutes
Lie down and the surface reads cool right away. That is the phase-change InfiniCool Lux cover doing its job before you have even settled in, and it is the easiest part of this bed to feel on the showroom floor. Press a hand in and the ActiveResponse foam gives a little, then pushes back, so you settle into the comfort layers without disappearing into them. Underneath, the zoned T2 coils carry your hips and shoulders and keep your spine in line whether you are on your back or rolling to your side. The whole feel is balanced: supportive, not stiff, with cushioning that relieves pressure instead of swallowing you.
Living with it over time
Two things matter most night after night. Cooling is the headline: the carbon fibers in the RightTemp Wave Foam are real, conductive material that moves heat away from the surface, which is why this is one of the cooler mediums on the floor below the Black tier. No mattress is air conditioning, but if you sleep warm, you will feel the difference here. Motion is the other: the T2 coils move independently, so a partner shifting or getting up barely crosses to your side. The bed also flexes on an adjustable base, so the medium feel holds up for reading and zero-gravity positions.
Who it is not for, said straight
- If you want the Black tier specifically: Beautyrest Black adds the three-wire T3 coil system and 2K/4K Micro Coils; the Black Series One Medium is the entry into that line.
- If you want plush or firm: this is a true medium and it will not become softer or firmer with time. Ask the floor about Beautyrest options in other feels.
- If you want the memory-foam hug: this is a responsive coil hybrid, not an enveloping all-foam bed.

What makes this mattress different
Zoned T2 pocketed-coil support
Two-wire T2 coils, each wrapped on its own, with firmer coils down the center third to carry your hips. Targeted support plus strong motion separation.
Carbon-fiber RightTemp cooling
Conductive carbon fibers built into the RightTemp Wave Foam move heat off the surface. This is the line's cooling signature, not a marketing word.
InfiniCool Lux phase-change cover
A phase-change finish that reads cool the instant you touch it, the easiest part of this bed to feel on the showroom floor.
ActiveResponse comfort foam
Responsive contouring that relieves pressure and pushes back, so you settle in without the slow-sinking memory-foam hug.
BeautyEdge foam-encased edge
A firm foam perimeter wraps the coils, so the mattress holds its shape when you sit or sleep near the side.
True medium, 13.5-inch profile
A genuine 5-of-10 feel suited to back, side, and combination sleepers, on a tidy height worth measuring against deep-pocket sheets.
Adjustable-base compatible
Built to flex on an adjustable base, so the medium feel holds up for reading and zero-gravity positions. Pair it with a base on the floor.
CertiPUR-US foams, 10-year warranty
CertiPUR-US certified comfort foams and a recycled cover knit with side handles, backed by a 10-year limited warranty from Beautyrest.
Carbon-cooled comfort on a zoned, targeted-support coil system
Start at the core. The Harmony Lux Hybrid runs Beautyrest's Precision Support System with T2 Pocketed Coils. T2 means two wires twisted together before the coil is formed, which makes the coil stiffer than a standard single-wire coil; Beautyrest Black steps that up to three-wire T3. The support unit is zoned, with the firmer coils concentrated in the center third under your hips, and a BeautyEdge foam perimeter wrapping the whole thing so the edges hold their shape.
Now the comfort layers. On top of the coils sit ActiveResponse Memory Foam for responsive pressure relief and RightTemp Wave Foam, which carries conductive carbon fibers that pull heat away from the surface. The cover finishes it with an InfiniCool Lux phase-change treatment that reads cool to the touch the moment you lie down. The result is a genuinely cool, balanced medium, about 5 out of 10, a step below the Black tier.
Want to feel what Black adds? The Black Series One Medium is the entry into that line. Compare both in the Beautyrest lineup, or come lie on them side by side at any of the five Kentucky showrooms.

Five layers, engineered together: a cool quilted surface, pressure-relieving gel foam, and the Triple-Stranded Pocketed Coil® core that defines the Black line.
The value sweet spot for a cool medium
Back sleepers: a true medium over zoned T2 coils keeps your spine in line while the comfort layers ease the small of your back. One of the safest picks in the Beautyrest lineup for you.
Combination sleepers: the medium feel and responsive ActiveResponse foam let you change positions through the night without fighting the bed or getting stuck.
Hot sleepers: carbon-fiber RightTemp foam and the InfiniCool Lux phase-change cover target heat directly. This is one of the cooler mediums on the floor below the Black tier.
Couples: the T2 coils move independently, so a partner shifting or getting up barely crosses to your side, and the BeautyEdge perimeter lets you both use the full width of the bed.
Value-minded shoppers: genuine Beautyrest engineering and real cooling without the Black premium. This is the bed to feel before you decide whether Black is worth the step up.
Probably not for you if you want a plush or firm feel, the deep memory-foam hug, or the Black tier specifically. For Black, start with the Black Series One Medium.

Frequently asked questions
How is Harmony Lux different from Beautyrest Black?
Harmony Lux is Beautyrest's premium line one step below Black. It uses two-wire T2 Pocketed Coils and RightTemp carbon-fiber cooling; Black steps up to the three-wire T3 coil system and adds 2K/4K Micro Coils on its higher tiers. Harmony Lux is the value sweet spot; Black is the step up. Feel both: the Black Series One Medium is the entry into Black.
How firm is it?
A true medium, about 5 out of 10 where 10 is firmest. It is comfortable for back, side, and combination sleepers, with responsive ActiveResponse foam over zoned T2 coil support. It will not change feel over time, so if you want plush or firm, this is not the model to soften or firm up into.
Does it actually sleep cool?
It is built to. RightTemp Wave Foam uses conductive carbon fibers to move heat away from the surface, and the InfiniCool Lux cover carries a phase-change finish that reads cool to the touch. It is one of the cooler mediums on our floor below the Black tier. No mattress is air conditioning, but the carbon fibers are real, testable engineering rather than a marketing word.
What are the T2 coils, exactly?
T2 stands for a coil made from two wires twisted together before it is formed, which makes it stiffer and more durable than a standard single-wire coil. Beautyrest Black uses the three-wire T3 version. The support unit is zoned, so the firmer coils sit in the center third under your hips, where most people sink first, and each coil is wrapped on its own for motion separation.
Is it good for couples and motion?
Yes. Because each T2 coil is individually wrapped and moves on its own, a partner turning over or getting up barely carries across the bed. The BeautyEdge foam-encased perimeter also keeps the edges firm, so two people can use the full width without feeling like they are rolling toward the middle.
Will it work on an adjustable base?
Yes. The Harmony Lux Hybrid is built to flex on an adjustable base, which holds the medium feel for reading and zero-gravity positions. Ask the floor about the adjustable bases we carry and how they pair with this mattress. You do not need a box spring; a flat platform or slatted frame with proper support works too.
How thick is it, and what about sheets?
The Ocean View Island Medium has a 13.5-inch profile. Most standard deep-pocket fitted sheets handle that height comfortably, but it is worth measuring against your current sheets and bed frame before delivery so the fit is right from night one.
What about certifications and fiberglass?
The comfort foams are CertiPUR-US certified, which means they are tested for content, emissions, and durability, and the cover knit uses recycled fibers. Beautyrest does not publicly publish the fire-barrier material for every model, so if a fiberglass-free fire barrier is a must-have for you, ask the floor to check the law tag on the exact unit before you buy. We would rather you confirm it than guess.
How do delivery and the comfort guarantee work?
Delivery across Kentucky is handled by the Mattress Overstock team, usually next business day when your size is in stock, with free setup and old-mattress haul-away. You also get a 100-day comfort guarantee: if the feel is not right, exchange it for store credit toward any bed of equal or greater value. There is no cash refund, but there are no restocking-fee games either.
