by The Douglas Summit is a 12-inch all-foam mattress made in Canada by GoodMorning.com. Its gel-foam and Elastex transition layers make it a solid medium-firm pick for side and back sleepers who want good motion isolation in a bed-in-a-box. It sells only in Canada (CAD pricing). If you are in the US, the Saatva Classic is the closest equivalent at a similar price point with a longer trial and lifetime warranty.

Douglas Summit Mattress Review
The Douglas Summit is the premium tier in the Canadian Douglas lineup, sitting above the Douglas Original and the Douglas Alpine Hybrid. It is made entirely by GoodMorning.com, a Canadian direct-to-consumer brand, and ships only within Canada. At 12 inches tall, the Summit is two inches taller than the original Douglas and uses three foam layers plus a high-tech cooling cover to justify its higher price. Here is what the mattress actually delivers across the categories that matter.
Construction and materials
The Summit uses a straightforward three-layer foam stack under a removable CoolSense cover:
- Cover: CoolSense fabric with Infinitex plant-based fibers and CryoFusion nanofibres. It is machine-washable and notably breathable for an all-foam mattress.
- Comfort layer (2.5 inches): ecoLight gel foam with Polar phase-change material (PCM). The gel and PCM work together to absorb heat rather than letting it accumulate near the surface. The foam is open-cell and lighter than traditional memory foam, which helps with responsiveness.
- Transition layer (2.5 inches): Elastex foam, a latex-like material that adds a slight bounce. This is the layer that prevents the deep sink typical of a pure memory foam bed and makes repositioning easier.
- Support core (7 inches): High-density motion-isolation support foam. The extra thickness compared to the original Douglas is the main reason the Summit handles heavier body weights better.
Firmness and feel
The Douglas Summit lands at roughly 6 out of 10 on the standard firmness scale, putting it squarely in medium-firm territory. The Elastex transition layer keeps the bed from feeling purely foam-like; there is a modest pushback that makes it easier to roll over or change positions mid-night. You get contouring at the shoulders and hips without the bottoming-out sensation that plagued earlier all-foam beds.
The feel is noticeably different from a coil hybrid. If you have slept on a traditional innerspring and want that responsive, bouncy sensation, the Summit will feel denser and quieter, which is a feature for couples and a limitation for sleepers who dislike foam.
Performance: cooling, motion isolation, and edge support
Cooling
The Summit is the most cooling-focused mattress in the Douglas lineup. The combination of gel-infused ecoLight foam, PCM in the cover, and open-cell Elastex produces noticeably less heat retention than a standard memory foam bed. Independent lab tests score it around 7.6 out of 10 for cooling features. That said, a perception test from Sleep Foundation places it at 5 out of 10 for temperature control, which is honest: the Summit sleeps cooler than a basic foam mattress but will not match the airflow of a coil hybrid or a latex mattress if you run warm at night.
Motion isolation
This is where the Summit genuinely stands out. The dense foam stack absorbs motion very effectively, scoring around 8.8 out of 10 in lab tests. Couples who are light sleepers or who share a bed with a restless partner will find the Summit significantly better than any hybrid at this price point. Movement on one side of the bed does not register on the other.
Edge support
For an all-foam mattress the Summit holds its edge well, scoring around 7.5 out of 10. You can sit on the edge without the mattress folding under you, and the sleeping surface extends reasonably close to the border. It is not as firm at the edge as a coil system, but it does not collapse the moment you move toward the perimeter.
Sleep positions and body weight
The Summit's medium-firm feel works best for these sleeper profiles:
- Side sleepers under 230 lb: The ecoLight gel layer provides enough give at the shoulder and hip to relieve pressure without losing spinal alignment. Side sleepers over that weight may find the Summit too soft for adequate support.
- Back sleepers up to about 220 lb: The 7-inch high-density core gives enough lumbar support for most back sleepers. The Elastex layer keeps the hips from sinking disproportionately.
- Stomach sleepers: Not a great match for most stomach sleepers, especially those over 130 lb. The medium-firm rating allows the hips to sink into the foam, which pushes the lumbar into extension. A firmer mattress or a hybrid with coils serves stomach sleepers better.
- Combination sleepers: The Elastex transition layer reduces the drag of a pure memory foam mattress, making position changes manageable. The Summit is one of the more combination-friendly all-foam options.

Summit vs Douglas Original vs Douglas Alpine
The Summit costs about CAD $300 more than the Douglas Original (queen) and sits below the Douglas Alpine Hybrid in terms of edge support and coil bounce. What you are buying with the Summit upgrade is two extra inches of foam (12" vs 10"), the Polar PCM cover, and a more cooling-focused construction overall. The extra height is also useful if you have mobility issues or simply prefer a taller bed profile. The Alpine Hybrid, which adds pocketed coils, is worth considering if edge support and responsiveness are priorities over motion isolation.

- Machine-washable cover
- CertiPUR-US certified foams
- Adjustable-base compatible
- Ships only within Canada, no US availability
- Not ideal for stomach sleepers or heavier side sleepers over 230 lb
- No lumbar zoning (uniform support core)
- Prorated warranty from year 11
- Temperature control is better than average foam but not exceptional for hot sleepers
Who should buy the Douglas Summit
The Summit earns its place as the top all-foam option in the Douglas line for Canadian shoppers who want excellent motion isolation, a cooling-focused cover, and a 365-night trial. It is a strong pick for side and back sleepers under 230 lb, couples who want minimal disturbance from each other's movements, and anyone who prefers the feel of foam over coil bounce.
It is less suited to stomach sleepers, heavier sleepers who need firm lumbar support, or anyone who wants an ultra-cooling or ultra-responsive surface. The Summit also does not ship to the US, which is the most important practical limitation for American shoppers.
The Douglas Summit is a well-made, 12-inch all-foam mattress from Canada's GoodMorning.com. It delivers exceptional motion isolation, decent cooling, and a generous 365-night trial. The medium-firm feel suits most side and back sleepers under 230 lb. US shoppers: look at the Saatva Classic for a comparable premium sleep experience with a coil hybrid construction, 365-night trial, and lifetime warranty.
Frequently asked questions
Is the Douglas Summit available in the United States?
No. The Douglas Summit is sold exclusively in Canada through GoodMorning.com and ships only to Canadian addresses.
Is the Douglas Summit flippable?
No. The Summit is a one-sided mattress with a comfort layer on top and a firm base below. Flipping it would put the dense support foam on top, which is not designed for sleeping.
Does the Douglas Summit come in a box?
Yes. It ships compressed and rolled in a box via FedEx. Expect the foam to fully expand within 24 to 48 hours of unboxing. The CoolSense cover is removable and machine-washable.
Is the Douglas Summit good for back pain?
For non-specific lower back pain, the medium-firm feel is in the range most physio and sleep research recommends. The Elastex transition layer provides some pushback under the lumbar region. That said, the Summit has no dedicated lumbar zoning, so sleepers who need targeted lower-back support may prefer a mattress with a reinforced lumbar zone, such as the Saatva Classic or the Douglas Alpine Hybrid.
How does the Douglas Summit compare to the Douglas Original?
The Summit is 2 inches taller (12" vs 10"), uses a Polar PCM cooling cover, and has an enhanced ecoLight gel layer for better temperature regulation. It costs about CAD $300 more at queen size. If cooling and height are priorities, the Summit is worth the premium. If you sleep cool or are on a tighter budget, the Original delivers a similar medium-firm feel.
