Bottom line
Consider Summit if you are in Canada and want the deepest cushioning and strongest pressure relief in the Douglas foam lineup. Choose Alpine to spend less, or look elsewhere if you want coil bounce, firmer stomach-sleeper support, or delivery outside Canada.

What supports this
Watch-outs
How we reached it
- Testing showed top-tier pressure relief.
- The 12-inch profile has deeper comfort layers than Alpine.
- The current build uses 2.5 inches of cooling gel foam over 2.5 inches of Elastex foam.
Pressure-relief testing produced a raw score of 10/10. Sinkage measured 1.85–1.93 inches (minimal), with a 5.0-inch comfort and transition stack on a 12-inch profile. The score reflects that result alongside the official comfort-layer construction, while still treating individual shoulder, hip, and back fit as personal.
- Testing showed minimal sinkage.
- The support layer is 7 inches thick in the current construction.
- The medium-firm feel supports back sleeping without a rigid surface.
- Strict stomach sleepers over 230 lb may prefer a firmer or hybrid model.
- Shoppers who want coil lift should compare Douglas hybrids.
The tested medium-firm surface allowed 1.85–1.93 inches of sinkage over a 7-inch support-foam core. That balance keeps back sleepers lifted while the deeper comfort system cushions side sleepers. Heavier stomach sleepers may need firmer or more buoyant support.
- Testing showed low motion-transfer acceleration.
- The all-foam build absorbs movement.
- Low bounce keeps partner disturbance calmer.
Peak-to-peak acceleration of 5.14–5.36 m/s^2 maps to 9.9/10 under our published motion scale. The surface mostly recovered in 0.196–0.204 seconds and fully recovered in 0.39–0.41 seconds, while bounce measured 6.11–6.35 inches. Those response and bounce measurements explain the calm but responsive feel and are scored separately under ease of movement.

- CryoFusion cooling nanofibres are built into the cover.
- The comfort layer uses cooling gel foam with Polar temperature balancing.
- Testing showed cooling in the strong range.
Cooling testing produced a raw score of 9.0/10, while sinkage measured 1.85–1.93 inches. The cover, gel foam, Polar temperature balancing, and foam contact depth make Summit stronger than a basic all-foam mattress for heat buildup, even though it still does not breathe like a coil hybrid.
- Testing showed 2.69–2.81 inches of sitting-edge compression.
- Lying edge support was reported as excellent.
- Minimal sinkage supports the perimeter.
Edge-support testing scored 9.3/10; sitting compression measured 2.69–2.81 inches, and lying edge support was rated excellent. Both sitting and lying results support using the full mattress width.

- Most recovery occurred in 0.196–0.204 seconds and full recovery in 0.39–0.41 seconds.
- Minimal sinkage limits the depth of the body impression.
The surface mostly recovered in 0.196–0.204 seconds and fully recovered in 0.39–0.41 seconds. Its 1.85–1.93-inch sinkage and 6.11–6.35-inch bounce results support an easy-moving feel despite the substantial comfort system.
- The 12-inch build has more material depth than Alpine or Original.
- The 7-inch support-foam core gives the deeper comfort stack a substantial foundation.
- Comfort foam can still soften with long-term use.
- Complete foam-density specifications are not disclosed.
The 12-inch all-foam construction combines 5 inches of comfort and transition foam with a 7-inch support core. Douglas does not publish complete foam densities, however, so long-term confidence remains below the top tier.
- Trial: 365 nights
- Eligible return cost: Free eligible mattress returns
- Warranty: 15-year warranty
- Minimum trial period: 21 nights after delivery
- Douglas covers return shipping for eligible mattress returns; remote delivery fees can still apply at purchase.
- Douglas limits sleep trials to one per household across GoodMorning.com mattress brands and requires returned mattresses to be undamaged and unsoiled.

Marketing vs. reality
What the claims mean in practice
ClaimBrand saysReality checkBuyer impact
Advanced cooling
SupportedDouglas positions Summit as advanced cooling for the coolest sleep in the foam lineup.
The cooling cover, gel foam, Polar technology, and testing support the claim for foam.
A good fit for hot sleepers who still want foam contour, but not the same airflow as a coil hybrid.
Deep pressure relief
SupportedDouglas says Summit uses deep foam layers for soothing pressure relief.
Supported by the 12-inch profile, 5 inches of comfort and transition foam, and excellent pressure-relief measurements.
This is the main reason to pay more than Alpine.
Broader 20-year warranty references
Policy riskThe broader Douglas warranty page still describes mattresses as having a 20-year warranty.
Summit product-specific copy uses a 15-year warranty.

What to know before buying
Fine Print Check
Fine print
Policy source
Policy details that can change the decision
AreaWhat Douglas saysWhy it matters
Trial and return window
Douglas gives mattresses a 365-night trial and allows returns from night 21 through night 365 after delivery.
The trial is strong buyer protection, but it is not a day-one return policy.
Warranty update
Douglas Summit product-specific copy uses a 15-year warranty, while the broader Douglas warranty page still describes mattress coverage as 20 years.
Buyers should rely on the current product-specific 15-year warranty rather than treating the broader 20-year wording as Summit's coverage.
Shipping geography
Douglas says shipping is free on all products but fees can apply to Canadian territories and certain remote areas.
US shoppers should not assume the Canadian shipping and return terms apply to them.

Inside the mattress
Construction & materials
CoverCryoFusion cooling nanofibre cover · Top
Machine-washable cover with Douglas cooling positioning. As the surface textile, it chiefly affects the initial hand feel, moisture movement, and how readily heat leaves the sleeper; it supplies little of the mattress's deep support.
Why it matters: Across the Douglas Summit Mattress, testing showed cooling in the strong range. Treat the cover as one part of thermal comfort rather than proof that the mattress will stay cool for every sleeper.
Comfort layerecoLight cooling gel foam with Polar temperature balancing · Top
2.5"
Adds deeper contour and cooling intent than Alpine. This foam distributes load through the comfort stack. Its position, thickness, and firmness matter more than a gel infusion or branded name alone when judging contour and support.
Why it matters: For the Douglas Summit Mattress as a whole, testing showed top-tier pressure relief. Near the surface it contributes more cushioning; deeper in the mattress it primarily moderates the transition into the support core.
Transition layerElastex foam · Middle
2.5"
Latex-like foam adds responsiveness and transition support without latex. This layer buffers the sleeper from the firmer support core and controls how gradually resistance increases as the body sinks deeper.
Why it matters: In the finished Douglas Summit Mattress, testing showed minimal sinkage. It becomes especially important for higher-weight sleepers and back or stomach sleepers, who engage more of the mattress depth than lighter sleepers.
Support coreMotion-isolation support foam · Support
7"
The support foam stabilizes the mattress and helps isolate movement. This foundation resists deep compression and keeps the comfort layers working on a stable plane; it is not intended to provide the mattress’s initial plushness.
Why it matters: Across the Douglas Summit Mattress, the 7-inch support-foam core gives the deeper comfort stack a substantial foundation. Its thickness and material quality are more relevant to long-term shape retention and bottoming-out resistance than to surface softness.
