The Level 3 Plush is the soft end of Beautyrest's World Class line, and that single word, plush, tells you almost everything about who it's for. Beautyrest positions World Class as a step up from the standard Beautyrest Collection, but explicitly below the Black Collection's luxury upgrades. So you're buying the middle tier, tuned soft.
I've spent years pulling these Simmons-built innerspring beds apart on paper, and the World Class platform is a genuinely conventional design executed with more coils than most beds at the price. That's the whole pitch. Let's look at whether the plush build holds up.
What's actually inside the Level 3 Plush
The headline spec is 1000 Density Pocketed Coil Technology. Per Beautyrest's own description of the World Class collection, that higher coil count plus higher-density foams is what separates World Class from the entry Beautyrest Collection, and the stated benefits are individualized support and motion separation. Sit 'n Sleep repeats that framing on its World Class Level Three Plush listing, calling out the 1000-density coil unit and the higher-density foams as the reason to step up.
Above the coils, Beautyrest's product page for the Level Three Plush lists SurfaceTouch Gel Memory Foam and InfiniCool MAX. Bedplanet's listing for the same mattress describes the result as a soft, contouring plush feel aimed at side sleepers.
Two construction notes matter more than the marketing names. First, pocketed coils are individually wrapped, which is why the motion-separation claim is credible rather than aspirational: each coil compresses on its own instead of dragging its neighbors. Second, a plush comfort layer on an innerspring unit is doing two jobs at once, cushioning the coil tops and providing pressure relief. When plush innersprings fail early, it's almost always the comfort layer softening, not the coils dying.
The Nut's read on "density": a 1000-density coil unit means finer, more numerous coils. More coils generally means better point-by-point contouring and less roll-together. It does not automatically mean more durable, because coil gauge and steel quality matter too, and Beautyrest doesn't publish gauge figures for this model.
Plush vs Plush Pillow Top: they're two different beds
This trips up shoppers constantly, and GoodBed maintains separate model pages for the Level 3 Plush and the Level 3 Plush Pillow Top for good reason. They aren't the same mattress with a marketing variant.
The straight Plush is Beautyrest's quilted innerspring build with a soft top. The Plush Pillow Top adds a sewn-on pillow top layer, which is described as delivering deep, cradling surface softness with extra pressure relief at the shoulders and hips. In practice, the pillow top version sleeps softer at the surface and sits taller in the frame.
| Consideration | Level 3 Plush | Level 3 Plush Pillow Top |
|---|---|---|
| Surface feel | Soft, contouring quilted top | Deep, cradling; softest of the two |
| Coil unit | 1000 Density Pocketed Coil, per Beautyrest | Same World Class coil platform |
| Best for | Side sleepers who still want coil pushback | Side sleepers needing max shoulder and hip relief |
| Profile | Lower | Taller, needs deeper sheets |
| Pricing seen | $1,599 at GoodBed; $1,399.99 at Sit 'n Sleep | $1,399 to $1,899 range at GoodBed |
My advice: if you're a side sleeper under roughly average weight and you wake with a sore shoulder, the pillow top is the more logical buy. If you like softness but hate the sinking-into-quicksand sensation, take the straight Plush.
Who this mattress suits, and who should walk away
Beautyrest's own guidance on the World Class Level Three is blunt: buy it if you want an upgraded mattress with premium benefits, understanding that it's an upgrade over the Beautyrest Collection but does not include the Black Collection's luxury upgrades. That's an honest positioning statement, and I'll extend it with construction logic.
Good fit
- Dedicated side sleepers. Bedplanet's listing frames the plush feel squarely at side sleepers, and the physics agree: soft top layers let the shoulder drop so the spine stays neutral.
- Couples sensitive to movement. Pocketed coils are the reason Beautyrest markets motion separation on this platform.
- Anyone who wants a traditional coil bed rather than an all-foam box. This feels like a mattress, not a mattress-shaped sponge.
Poor fit
- Back and stomach sleepers. A plush surface lets the hips settle below the shoulders, which is how you wake up with a low-back ache.
- Heavier sleepers. The more you weigh, the faster you compress a plush comfort layer, and the more you'll notice the coils underneath.
- Shoppers who want a documented in-home trial and long-warranty story before buying. Those terms vary by retailer here, so confirm them in writing at checkout.
Cooling: what InfiniCool MAX does and doesn't promise
Beautyrest lists InfiniCool MAX on the Level Three Plush alongside SurfaceTouch Gel Memory Foam. Read that as surface-level heat management: gel-infused foam and a cooler-to-the-touch top, not active cooling.
Here's the construction reality I'd want a shopper to understand. Innersprings breathe better than solid foam slabs because air moves through the coil layer, so a coil-on-bottom, foam-on-top build like this one has a structural advantage over a thick all-foam mattress. But plush means you sink further into the foam, and sinking reduces airflow around your body. The two effects partly cancel out. If you run genuinely hot, a plush build is working against you no matter what the cooling layer is called.
Durability: where a plush innerspring wears first
Nobody publishes coil gauge for this model, so I won't pretend to know it. What I can tell you from a decade of watching this category is where plush innersprings degrade.
The comfort layer goes first. Softer foams and fiber quilting compress under repeated load, and because you always sleep in the same spot, you get a body impression before you get a coil failure. Higher-density foams, which Sit 'n Sleep specifically credits to the World Class collection, slow that process. They don't stop it.
Two practical moves extend the life of any plush innerspring. Use a rigid, properly slatted or solid foundation, because coil units flex where they're unsupported and that flex becomes sag. And rotate the mattress head-to-foot on a regular schedule to spread the wear, which works on a no-flip pillow top too.
Buying tip: plush pillow tops are the single hardest mattress type to judge in a showroom. Five minutes on your back tells you nothing about how the comfort layer behaves after six months. Get the retailer's comfort-exchange and warranty terms in writing before you pay, since those policies differ between Beautyrest's own site and third-party dealers.
Price: a wide range, and it matters
The pricing picture here is genuinely scattered. Sit 'n Sleep lists the World Class Level Three Plush at $1,399.99, with $1,000 also appearing in its pricing for the model. GoodBed shows $1,599 on its Level 3 Plush page, and its Level 3 Plush Pillow Top page spans $1,399, $1,599, $1,699 and $1,899.
That spread tells you two things. First, size and configuration drive a big chunk of the difference, so a queen quote is not a king quote. Second, this line is discounted regularly by dealers, so the sticker you see first is rarely the sticker you pay. Get quotes from at least two retailers on the exact size and exact model name, Plush versus Plush Pillow Top, before you commit. Check the current price on the official site as your baseline.
How it sits against the rest of the World Class line
Level 3 is not the top of this collection, and the differences are worth understanding before you settle. If you want the same plush direction with more of the collection's build, the Level Four Plush Pillow Top is the step up in the same feel category. If you'd rather trade some softness for support, the Level Three Medium Hybrid keeps the same tier while moving to a firmer, hybrid construction, and the Level Three Hybrid is the other configuration to compare at this level. Shoppers stretching their budget should also look at the Level Four Hybrid.
For broader context, luxury innerspring hybrids built with a firmer coil-and-foam split, such as the Saatva Classic, take a different approach to the same side-sleeper problem by pairing coil support with a targeted lumbar zone rather than a deep plush top. Which philosophy suits you depends on whether your shoulder or your lower back is the thing waking you up.
The verdict
The Level 3 Plush is a competent, conventional plush innerspring with a coil count that justifies the World Class name. The 1000-density pocketed coil unit is the real feature, and Beautyrest's motion-separation claim is well founded on that construction. If you're a side sleeper who wants a soft surface over responsive coils, this earns a look.
Where I'd hesitate: it's the middle tier of Beautyrest's ladder by the brand's own description, the cooling story is surface-level rather than structural, and plush comfort layers are the fastest-wearing part of any innerspring. Heavier sleepers and back or stomach sleepers should look at the medium and hybrid configurations in the same line instead. And because pricing runs from four figures at the low end up to $1,899 for pillow-top configurations at GoodBed, the same bed can be a solid value or a mediocre one depending entirely on which retailer you walk into.

FAQ
Is the Beautyrest World Class Level 3 Plush good for side sleepers?
Yes, that's its target sleeper. Bedplanet's listing describes the soft, contouring plush feel as built for side sleepers, and the Plush Pillow Top variant is specifically framed around extra pressure relief at the shoulders and hips.
What's the difference between World Class and Beautyrest Black?
Beautyrest states plainly that World Class is an upgrade from the Beautyrest Collection but does not include the luxury upgrades found in the Beautyrest Black Collection. World Class is the middle rung, not the top.
How much does the Level 3 Plush cost?
It varies a lot by retailer and size. Sit 'n Sleep lists it at $1,399.99, GoodBed shows $1,599 for the Plush, and GoodBed's Plush Pillow Top page ranges from $1,399 up to $1,899. Compare at least two dealers on the identical size and model.
What is 1000 Density Pocketed Coil Technology?
It's Beautyrest's individually wrapped coil unit at a high coil density. Per Beautyrest and Sit 'n Sleep, the 1000-density unit plus higher-density foams is what delivers the collection's individualized support and motion separation.
Do I need a special foundation for this mattress?
You need a rigid, well-supported base, whether that's a matching foundation or a solid platform with closely spaced slats. Unsupported spans let the coil unit flex, and that flex turns into sag, which is also the fastest way to run into a warranty exclusion. Confirm the base requirements with your retailer.
