Delivery, Sleep Trial & Returns

Douglas relies on FedEx for most Canadian deliveries and will ship for free directly to your doorstep. However, there may be added fees if you live in a remote area. Your mattress should arrive within 3–10 business days, depending on where you live and whether it’s shipped from Ontario or Alberta.

Your Douglas Summit is ready for a comfortable night’s rest two minutes after unpacking. You’ll then enjoy one of Canada’s lengthiest sleep trial policies at 365 nights. If the mattress doesn’t suit your needs, the company will organize a free pickup and issue a full refund.

Douglas Summit Mattress Construction

HeightLayersCertiPUR-US® CertifiedMachine Washable Cover





Douglas Summit stands 12″ tall and has the same 3 specialty foam layers as Douglas Original and Douglas Alpine. However, each layer has been rebalanced for improved comfort and support:

  • Layer 1: The comfort layer features 2.5″ ecoLight® cooling gel foam, which is lighter, more durable, and more eco-friendly than traditional memory foam. It effectively dissipates heat and improves air circulation. This layer is enhanced by Polar® Temperature Balancing, a phase-change material that regulates mattress temperature. Foam density: 2.5 lb/ft³.
  • Layer 2: The transition layer is 2.5″ of Elastex® foam. This offers both springiness and support, similar to the way many mattresses use latex. But unlike latex, this foam is free from allergy-triggering chemicals. Foam density: 1.85 lb/ft³.
  • Layer 3: The support layer, which makes up half of the mattress’s overall height, is 7″ of motion-isolation foam. Designed to provide exceptional motion isolation support, it virtually eliminates any transfer of movement from the other side of the bed. Foam density: 1.85 lb/ft³.

The Douglas Summit CoolSense® cover is made from high-density polyethylene, polyester, and spandex. This cover also features sustainable Infinitex™ fibers and CryoFusion™ cooling nanofibres, which efficiently wick away moisture from the mattress’s surface. Combined with the cooling gel foam in the top layer, the cover fabric will help keep you cool and dry all night.

Mattress Performance Results

6.7 /10


In third-party engineer testing (commissioned by us), Douglas Summit scored 6.7/10 for firmness. This places Summit in the medium-firm category—a level of firmness that’s ideal for all sleep styles and preferred by many Canadians. A medium-firm feel provides a good balance of comfort and support.

7.5 /10

Edge Support

Foam mattresses aren’t known for their edge support, but Douglas Summit stands out in this department. It received an above-average rating of 7.5/10 in engineer testing. The edges are nicely cushioned without causing you to sink too far into the mattress. As a result, you can sit on the edge without falling off, and it doesn’t take much effort to get out of bed.

8.8 /10

Motion Isolation

Any surface movement on your bed can interrupt your sleep and lead to chronic fatigue—especially if you are a light sleeper and share your mattress with a partner or pets. Douglas Summit has the highest motion isolation score of any mattress we’ve ever reviewed at 8.8/10. That means you won’t notice any light-to-moderate movement from the other side of the bed.

3.0 /10


Given its exceptional motion isolation, Douglas Summit has below-average bounce with a low score of 3.0/10. Any pressure you apply to the mattress is promptly absorbed. At the same time, you won’t have any trouble changing sleep positions, thanks to the responsive layer of Elastex foam.

Cooling Features

The Douglas Summit mattress has the most advanced cooling technologies in the Douglas lineup, even more than Douglas Original or Douglas Alpine. When combined, these cooling features adapt to your body’s needs to avoid retaining excessive heat and to keep temperatures comfortable. Douglas Summit earns points for its:

  1. CoolSense® cover that draws moisture away for a cool, dry feel
  2. CryoFusion™ cooling nanofibres in the top cover that make it even cooler to the touch
  3. Layer of ecoLight® cooling gel foam that allows for enhanced cooling
  4. Phase-change material that adapts to body temperature and prevents heat retention
  5. Layer of Elastex, a breathable latex-like foam that ensures good air circulation

Douglas Summit performs well in every category, but adds even more comfort than other Douglas models with the addition of cooling nanofibres. This comfort comes at an accessible price tag of just $1,299 for a queen size. (Want to take your mattress’s cooling features to the next level? Consider Octave Vista instead.)
