Douglas Summit vs Evergreen ecoRest: Mattress-in-a-Box vs In-Store Organic Latex Options in Canada

If you are stuck comparing mattress-in-a-box brands to each other, you are not alone. The online mattress world is loud, affiliate-heavy, and often short on the exact specs that actually predict comfort and durability. This guide breaks that loop by comparing the Douglas Summit (a premium mattress-in-a-box option) to the Evergreen ecoRest collection available through National Mattress. The goal is not to “win an argument” about online vs retail. It is to help you make an informed decision with real specs, realistic tradeoffs, and a practical “what to feel for” plan you can use in-store.

Who this comparison is for:

• Canadian shoppers comparing Douglas Summit vs other bed-in-a-box models and wanting a legitimate retail-store alternative.
• Sleepers who prefer medium to medium-firm comfort and want clear, technical specs (foam density, coil count, coil gauge) when available.
• Anyone who wants to try mattresses in-store and compare brands like Sealy, Serta, and Beautyrest side by side, not just read rankings.

Disclosure + pricing note: This article is written for National Mattress shoppers and published on nationalmattress.ca. Prices shown are in Canadian dollars and can change with promotions, availability, and seasonality. Evergreen ecoRest specs and pricing are based on National Mattress product data. Douglas specs and pricing are based on publicly available manufacturer information.

Quick Verdict

Best Overall Value (for most shoppers):

Evergreen 12" Tight-top Medium-Firm Organic Latex Mattress (ecoRest collection)

• Price-to-spec is excellent: a Queen is typically far less than premium mattress-in-a-box pricing, while still using a pocket-coil support unit and organic latex comfort materials.
• Support system is clearly defined: pocket coils with listed coil gauge and coil count (a big deal when you want apples-to-apples comparisons).
• In-store advantage: you can test it against other proven retail options in the same trip, including Sealy, Serta, and Beautyrest.
• More “mattress store feel”: buoyant latex plus coils, easier to move on than many all-foam beds.

Note: If you prioritize the longest at-home trial and the “quietest” feel for couples, Douglas Summit still has a strong case. Keep reading for the technical breakdown.

Mattress Breakdown

The big point most online comparisons miss

“Mattress-in-a-box” is a delivery format, not a quality guarantee. Some boxed beds are well made. Some are not. The same is true for retail mattresses. The real differentiator is whether you can verify the build and match it to your body.

From a design and manufacturing perspective, the highest-leverage specs you can compare are:

• Foam density (lb/ft³): higher density support foams generally resist premature softening better.
• Coil gauge: thicker wire (lower gauge number) is typically more supportive and tends to hold up better under higher loads.
• Coil count (and coil design): not everything, but a real clue to contour and stability when comparing similar coil systems.
• Edge support method: foam encasement and coil design impact how stable the perimeter feels sitting or sleeping near the edge.
• Layer thickness and materials: latex, memory foam, high-resiliency foam, quilt fibers, and cover fabrics all change the feel.

That is why retail-store shopping still matters. At National Mattress, you can test ecoRest next to proven national brands like Sealy, Serta, and Beautyrest in one visit and make a decision based on your body, not an algorithm.

Tip: If you want a boxed mattress specifically, National Mattress also carries options in the Mattress in a Box category so you can compare delivery formats without limiting yourself to online-only brands.

Mattress Sizes & Prices

All prices below are in Canadian dollars. Evergreen ecoRest pricing comes from National Mattress product data. Douglas pricing comes from the manufacturer’s listed pricing for the Summit model.

Quick reality check: On a Queen size, the ecoRest hybrid is typically about C$654 less than Douglas Summit, while the ecoRest latex foam model is typically about C$132 less. That is why retailers with broad selection can be such a strong value if you compare specs instead of marketing.

Mattress Performance Results

Performance is where most mattress marketing gets fuzzy because there is no universal industry lab scorecard published for every model. The ratings below are engineering-based expectations derived from construction (materials, layer thickness, coil system, latex vs memory foam behavior) plus the firmness ranges stated in product specs where available. Use them as a guide, then verify by testing in-store or during the trial period.

Firmness

Firmness is weight-dependent. A “medium” mattress can feel firmer to a 120 lb sleeper and softer to a 230 lb sleeper. When comparing, do not just rely on the label. Look at the build: coil gauge, foam type, and comfort layer thickness tell you more than a tag.

• Douglas Summit: medium-firm all-foam. Expect more contour, especially at shoulders and hips.
• ecoRest Hybrid: listed as medium with a slightly firmer “medium” feel. Coils and latex tend to keep the surface more lifted.
• ecoRest Foam: listed as medium, a touch more forgiving at first contact than the hybrid, with latex response.

Edge Support

Edge support is mainly a function of perimeter construction. Foam-encased coils and reinforced coil rows tend to hold shape better than most all-foam edges. If you sit on the edge to put on shoes or you sleep near the perimeter, this matters.

Motion Isolation

Motion isolation is the “partner disturbance” category. All-foam mattresses usually win because foam absorbs vibration. Pocket coils can still isolate well, but you will typically feel more movement than on a thick all-foam build.

Bounce

Bounce is not good or bad. It is a preference. Latex and coils create spring and “push-back.” Memory foam creates damped, slower response. Combo sleepers and people who change positions frequently often prefer more response.

Cooling

Cooling is a system, not a single feature. Cover fabrics, phase-change layers, quilt fibers (wool is naturally temperature regulating), latex breathability, and coil airflow all contribute. If you sleep hot, test in-store for 10 minutes, not 30 seconds. Heat build-up is time-dependent.

Mattress Construction

This is the section I wish more mattress comparisons led with. Construction details tell you how a bed will behave over years, not just nights. If a brand does not disclose a key spec (like foam density), that does not automatically mean it is low quality. It simply means you cannot fully validate the durability inputs.

Evergreen ecoRest 12" Tight-top Medium-Firm Organic Latex Mattress (hybrid)

Height: 12 inches

Comfort and quilt:

• Organic cotton quilted cover
• Organic wool in the quilt package
• Organic latex comfort (listed as 1 inch latex in the comfort stack)

Support system:

• Pocket coils: “1000 Series High Loft Pocket Coils” with bio-foam encasement
• Coil gauge: 13
• Queen coil count: 1,000 (King: 1,320; Double: 842; Twin: 572; Twin XL: 592)

Spec transparency callout:

• Coil gauge and coil count are disclosed, which helps real comparisons.
• Foam density for the foam layers is not specified, so long-term durability comparisons for the foam components are harder to validate.

Shop ecoRest Hybrid

Evergreen ecoRest 12" Medium-Firm Organic Latex Foam Mattress (foam core)

Height: 12 inches

Layer breakdown (listed):

1. Organic cotton quilted cover
2. 4 inch organic latex comfort layer (listed as “pocketed” latex)
3. 1 inch organic latex support panel
4. 7 inch open-cell bio-foam core

Foam density disclosure (important):

• Core foam density: 1.8 lb/ft³ (a solid durability baseline for a support core in many adult mattresses).
• Latex ILD and latex density are not listed, so you still rely on in-store testing for the final comfort feel.

Delivery, Sleep Trial & Returns

This is where retail and mattress-in-a-box brands often differ more than people realize. You should compare the real-world outcome: can you return for a refund, or is it exchange-only, and how does pickup work?

Why this matters: A 365-night trial is great if you want maximum time and a refund-based decision. A 100-night trial with exchange can be great if you want to buy from a retailer, test in-store first, and still have a structured safety net if you need a different feel. If you want the full details, see National Mattress 365 Night Sleep Trial.

Should You Buy Douglas, ecoRest Hybrid, or ecoRest Foam?

Below are practical “buy it if you want” checklists. Each one is designed to make your decision faster and more objective. If two lists sound right, that is your cue to visit a showroom and do a direct comfort test.

Buy or consider Douglas Summit if you want:

• A premium all-foam feel with strong pressure relief and a more “quiet” surface.
• Excellent motion isolation for couples or light sleepers.
• A long, at-home decision window (365 nights).
• A washable cover and a modern cooling-focused feature set.
• A mattress delivered in a box that is simple to get into condos, stairs, and tight hallways.
• A medium-firm feel that works for many back and side sleepers.
• Compatibility with adjustable bases.
• You are okay with foam density not being disclosed (you are trusting the brand’s engineering rather than verifying density numbers).
• Avoid if: you want a strong, sit-on-the-edge perimeter or you strongly prefer a springy latex-and-coil feel.

Buy or consider Evergreen ecoRest 12" Tight-top Medium-Firm Organic Latex (Hybrid) if you want:

• A responsive surface that is easier to move on than many all-foam mattresses.
• Pocket-coil support with listed coil gauge (13) and high coil count in Queen (1,000).
• More stable edge support (foam encasement plus coils) for sleeping or sitting near the perimeter.
• Natural-feeling comfort materials, including organic latex and organic wool in the quilt package.
• A strong value option that is typically much less expensive than premium mattress-in-a-box models in Queen.
• The ability to test in-store and compare quickly against Sealy, Serta, and Beautyrest models.
• A mattress that tends to sleep cooler than many classic memory foam comfort builds (latex and coils breathe).
• Canada-made build and retailer support from National Mattress.
• Avoid if: you want the deepest memory foam hug or you require a refund-based return after opening.

Buy or consider Evergreen ecoRest 12" Medium-Firm Organic Latex Foam if you want:

• A foam-core mattress that still feels responsive (latex comfort) instead of slow and sinking.
• A disclosed foam density on the support core (1.8 lb/ft³), which helps validate durability inputs.
• Medium comfort that is comparable to other medium-firm builds, with a slightly more forgiving top feel than the hybrid.
• A mattress that generally sleeps cooler than traditional memory foam comfort stacks.
• Less motion transfer than many coil hybrids, while still avoiding the “stuck” feel of slow memory foam.
• An all-foam build without coils, useful for some adjustable base setups and simpler support behavior.
• Canada-made construction with retailer support.
• You want a premium latex-forward feel but still want to spend less than Douglas Summit in many sizes.
• Avoid if: you dislike latex “push-back,” or you want coil springiness and very strong edge structure.

FAQs

Are mattress-in-a-box mattresses lower quality than retail mattresses?

Not automatically. “Mattress-in-a-box” describes how a mattress ships. Quality depends on materials, layer design, and durability inputs (like foam density or coil build). The advantage of retail is that you can usually compare more models side by side and validate feel faster.

Why do you keep mentioning foam density?

Foam density (lb/ft³) is one of the most useful durability signals for polyurethane and memory foams. It does not tell you everything, but it is a measurable input. If a brand does not disclose density, you can still buy it, but it becomes harder to compare long-term performance objectively.

Does higher coil count always mean a better mattress?

Not always. Coil count needs context: coil gauge, coil diameter, number of turns, zoning, and edge construction matter. That said, when comparing similar pocket-coil builds, coil count can help predict contour and stability.

What is the biggest in-store test I should do?

Spend 2 minutes in your main sleep position and check two things: pressure relief (shoulders and hips) and alignment (your lower back should not feel jammed or sagging). Then roll closer to the edge and see if you feel stable. Finally, have your partner move around to assess motion transfer.

If I want a brand name mattress like Sealy, Serta, or Beautyrest, how do I compare it to Douglas?

Compare the fundamentals: comfort layer thickness and material type, coil or core design, and any disclosed durability specs. Then do an in-store feel test. Start here: Sealy, Serta, Beautyrest.

Where can I learn how to shop more objectively?

Two helpful internal resources are the Ultimate Mattress Buying Guide and the Mattress Size Guide. If you want a faster shortcut, use the Find My Mattress tool to narrow your shortlist before visiting a showroom.
