Bloom Sol vs Sealy Cocoon Mattress Collection: A Technical Canada Comparison

If you have been stuck comparing mattress-in-a-box brands to each other, you are not alone. The online mattress space is noisy, and a lot of what ranks is written by affiliate sites that rarely go deep on the specs that actually predict long-term comfort and durability.

This article breaks that loop by comparing one popular mattress-in-a-box model (the Bloom Sol Mattress) against a national-brand mattress-in-a-box series you can buy through a Canadian retailer: the Sealy® Cocoon™ Mattress Collection available at National Mattress. The goal is not to shame anyone for shopping online. It is to help you make a more informed decision, and to remind you that big national brands like Sealy, Serta, and Beautyrest have genuinely robust options that deserve a spot on your shortlist.

Who this comparison is for

• You want a mattress-in-a-box for delivery convenience, but you still care about build quality and real-world performance.
• You like a plush feel (especially for side sleeping), and you are trying to avoid buying blind.
• You want to compare a direct-to-consumer style product against a national brand you can shop in a Canadian retail environment.
• You want practical in-store testing notes, not just marketing language.

Quick Verdict

When Bloom Sol can still be the better choice: If you specifically want Bloom Sol's feature set (including its layer blend and specialty foams) and you are already committed to the Sleep Country purchase flow, it can make sense. Just be aware that many important durability comparison specs (like foam density) are not typically published for apples-to-apples benchmarking.

Mattress Breakdown

How to read this comparison (technical but simple): In manufacturing terms, the "quality" of a mattress is not the brand name or the number of layers. Quality is primarily about component selection (foam type, foam density, and support core integrity), how those components are assembled, and whether the design matches your body and sleep position.

Here is the key difference between these options:

• Bloom Sol is positioned as a plush, multi-layer foam build with specialty materials (like gel memory foam and a latex-like support element) intended to blend contouring and support.
• Sealy Cocoon (Soft and Medium-Firm) is a simpler, more classic foam architecture: a breathable cover, a contouring memory foam layer, a comfort transition layer, and a durable base foam. Simpler is not worse. In many cases, it is easier to predict and more consistent long-term.

Why National Mattress (and retail testing) changes the quality conversation

When you only compare mattress-in-a-box brands online, you are usually comparing marketing claims, not measurable performance. The advantage of a retailer like National Mattress is that you can:

• Feel the differences between plush, medium, and firm in minutes.
• Compare national brands like Sealy, Serta, and Beautyrest that often offer more robust hybrid and innerspring designs than many online-only brands.
• Ask better questions about construction, support systems, and comfort layers, then compare alternatives in the same visit.

Specs transparency check (the part affiliate rankings rarely cover)

Two specs that matter a lot for long-term durability are foam density (for foam beds) and coil count plus coil gauge (for spring and hybrid beds). In this comparison, both Bloom Sol and Sealy Cocoon are all-foam, and foam density is not prominently disclosed in the public product info, which makes true durability comparisons harder than they should be.

The important takeaway is this: retail and national brands are not inherently lower quality. In fact, many National Mattress product listings for hybrid beds include concrete details like coil counts. For example, some Beautyrest hybrids are advertised with 1000 individually wrapped coils, which is the kind of spec you can actually compare across mattresses when you are shopping seriously.

Mattress Sizes & Prices

Prices below are in CAD. Promotions change frequently, so treat this as a snapshot for comparison, not a guaranteed checkout total.

Value note: If you are purely trying to maximize comfort-per-dollar in a foam mattress, the Cocoon Medium-Firm 8" has the lowest Queen price in this comparison. If you want a plush feel that is closer to Bloom Sol, compare Bloom Sol against Cocoon Soft first, then decide if plush is actually what your back wants long-term.

Mattress Performance Results

The scores below are based on material science expectations for foam builds, plus what you should pay attention to when you test these feels in-store. Foam performance is predictable: thickness, foam type, and how quickly the comfort layer lets you sink largely determine pressure relief, temperature feel, and edge behavior.

Firmness

Bloom Sol and Cocoon Soft live in the plush zone. That is excellent for many side sleepers because the shoulder and hip can sink enough to reduce pressure. The risk is that some back sleepers (and many stomach sleepers) will feel their hips drop too far, which can stress the lower back over time.

Cocoon Medium-Firm shifts you closer to a neutral alignment feel for a wider range of sleepers. It will not feel as "cloud-like," but it can be the safer pick if you are unsure between plush and medium.

Edge Support

These are all-foam mattresses. That means edge support is mostly about the density and thickness of the base foam and whether the comfort layer collapses too easily near the perimeter. Foam edges can feel stable for sleeping, but sitting on the edge to put on socks will typically compress more than a coil or hybrid mattress with reinforced perimeter support.

In-store feel note: Sit on the edge for 20 seconds, then slide toward the corner. If you feel like you are "rolling off," consider a hybrid (Sealy, Serta, and Beautyrest hybrids are often excellent for edge stability).

Motion Isolation

Foam is naturally good at damping vibration. The Cocoon line is designed around memory foam comfort, which typically produces excellent partner motion isolation. Bloom Sol should also perform well here due to its multi-layer foam stack.

Bounce

Bounce is where most foam beds lose to hybrids. If you change positions a lot, or you dislike the "stuck" sensation of slower memory foam, pay attention to response speed. Bloom Sol includes a latex-like foam element, which often increases responsiveness compared to a purely slow memory foam surface.

Cooling

Cooling claims are common, but here is the engineering reality: all-foam mattresses insulate more than coil systems because they move less air. Materials like gel infusions, ventilation holes, and breathable covers can help reduce the initial heat build-up, but deep sink will still feel warmer than a hybrid with airflow through coils.

Bloom Sol uses elements marketed for airflow and cooling comfort (like bamboo charcoal foam and gel memory foam). Cocoon uses a breathable premium fabric cover and a memory foam layer designed to contour and adapt.

Mattress Construction

Below is the construction breakdown using the most important specs available publicly. If a spec (like foam density) is not disclosed, I call that out because it matters when you are comparing durability across foam mattresses.

Bloom Sol Mattress (Plush, mattress-in-a-box)

• Type: All-foam mattress-in-a-box
• Height: 12" (as listed)
• Comfort level: Plush
• Disclosed foam density: Not disclosed in public product info
• Disclosed coil count: Not applicable (no coil unit listed)

Layer list (as described)

1. FIR cover (described as breathable with thermal protection)
2. Bamboo charcoal foam (described as enhancing airflow)
3. Advanced gel memory foam with quartz powder and ventilation holes
4. Gel memory foam combined with latex foam lumbar support
5. Bamboo charcoal convoluted foam layer

In-store feel notes (what to pay attention to)

• Expect a plush top with noticeable contour at shoulders and hips.
• The latex-like support element can add a slightly more buoyant transition than a pure memory foam bed.
• Check midsection support: on your back, your lower back should feel supported, not sagging.

Who should avoid Bloom Sol

• Strict stomach sleepers (plush foam often lets hips sink too far).
• People who want strong edge sitting support.
• Very heavy sleepers who want plush comfort but need a more robust support core (often better served by a hybrid with coils).

Sealy® Cocoon™ Soft 10" Plush Memory Foam (National Mattress)

• Type: All-foam mattress-in-a-box
• Height: 10" (as listed)
• Comfort level: Plush
• Disclosed foam density: Not disclosed in public retailer listing
• Disclosed coil count: Not applicable

Layer list (collection-level description)

1. Premium fabric cover (breathable stretch-knit style cover)
2. Perfect Fit memory foam (described as a higher-density comfort layer on some listings)
3. Personalized comfort layer (soft option for deeper pressure relief)
4. Essential support foam base (engineered for durability and resilience)

In-store feel notes (what to pay attention to)

• Expect a more classic memory foam "hug" with strong motion dampening.
• Focus on pressure relief on your side: shoulders should sink without numbing.
• Check ease of movement: roll from back to side and note whether you feel "stuck."

Who should avoid Cocoon Soft

• People who dislike slow-response memory foam or want a springy surface.
• Stomach sleepers who need firmer hip support.
• Anyone who wants a cooler, more ventilated feel (a hybrid is usually better).

Sealy® Cocoon™ Medium-Firm 8" Memory Foam (National Mattress)

• Type: All-foam mattress-in-a-box
• Height: 8" (as listed)
• Comfort level: Medium
• Disclosed foam density: Not disclosed in public retailer listing
• Disclosed coil count: Not applicable

In-store feel notes (what to pay attention to)

• Expect a more "support-forward" feel with less deep sink than plush models.
• Back sleepers: your hips should feel level and your lower back should not gap.
• Side sleepers: watch for shoulder pressure, especially if you are bony or broad-shouldered.

Who should avoid Cocoon Medium-Firm

• Lightweight side sleepers who need very plush pressure relief.
• Anyone who prefers a tall, deeply contouring foam feel.

Delivery, Sleep Trial & Returns

A sleep trial is only useful if you understand the fine print. Foam mattresses change feel over the first few weeks (break-in plus your body adjusting), so minimum-night requirements are common across the industry.

Practical return-proofing tips (do this no matter what you buy)

• Use a mattress protector from night one. Stains often void return eligibility.
• Take photos at unboxing and after expansion in case you need a warranty claim.
• Give foam at least a few weeks to stabilize in feel before deciding it is "too firm" or "too soft."

FAQs

Is a mattress-in-a-box automatically lower quality than a traditional mattress?

No. "Mattress-in-a-box" describes packaging, not quality. You can compress high-quality foams, and many reputable brands do it. The real quality questions are about the materials used (especially foam density for foam beds), how well the mattress supports your spine, and whether the design holds up over years of use.

Why do foam density and coil count matter so much?

Foam density is one of the most useful indicators of how well a foam layer will resist premature softening. Coil count and coil gauge help you compare the support system of spring and hybrid beds. If a brand does not disclose these, it does not mean the mattress is "bad," but it does make long-term durability harder to evaluate objectively.

Do these mattresses need a box spring?

Most foam mattresses do not require a traditional box spring. A supportive foundation or platform base is typically recommended. If you want a deeper guide on bases and compatibility, National Mattress has a practical article on what types of mattresses do not need a box spring. Read the box spring guide.

How should I test plush vs medium in-store so I do not regret my choice?

Lie down in your normal sleep position for 8 to 10 minutes, not 30 seconds. For side sleeping, focus on shoulder comfort and hip sink. For back sleeping, focus on whether your hips drop too far. Then sit on the edge for 20 seconds to test perimeter stability. This simple routine reveals more than most online comparisons.

What does CertiPUR-US certified foam actually mean?

CertiPUR-US is a foam certification program that tests flexible polyurethane foams for content and emissions. Certified foams must meet requirements such as being made without certain harmful chemicals and meeting low VOC emission limits for indoor air quality. It is a helpful baseline for many shoppers, but it is not the same as a full durability spec sheet.

If I want something more "robust" than an all-foam bed, what should I look at instead?

If you want stronger edge support, more airflow, and a more resilient support core, start looking at hybrids and innerspring hybrids from national brands. National Mattress carries broad lineups from Sealy, Serta, and Beautyrest, many of which publish concrete support-system details (like coil counts) directly on product pages.
