Motion isolation is a strong point of the Douglas Summit Mattress. During our tests, sleepers were able to get in and out of bed with minimal disruption to the other person.
The memory foam in the top layer is quick to conform when pressure is applied. This helps the material absorb movement before it can transfer across the bed. While it does have a slightly bouncier second layer, our testing found that this didn’t translate to bothersome vibrations from a bed partner moving on the other half of the bed.
All in all, the Douglas Summit Mattress transfers significantly less motion than a typical innerspring or latex mattress. Its above-average performance in this category makes the Douglas Summit an attractive option for those who sleep alongside a partner, a child, or a pet.

Higher price-point than the Douglas Original
Canadian company GoodMorning.com was founded in 2009 and currently produces multiple brands of mattresses, including the popular Douglas line, which includes the Douglas Summit Mattress.
Launched in 2017, the Douglas Original is a 10-inch all-foam foam mattress sold at a competitive price-point. Two additional models, the Douglas Alpine and the Douglas Summit, were subsequently added to the lineup.
The Douglas Summit is a 12-inch foam mattress. Like the other Douglas models, the Summit’s comfort system contains ecoLight cooling gel memory foam as well as latex-like Elastex foam. The support core is made with polyfoam. Compared to the Douglas Original, the Summit offers enhanced cooling features as well as a more robust comfort system and support core.
We’ll explore the specifications of the Douglas Summit and offer a brief comparison with the other Douglas models. We’ll also take a look at which types of sleepers are most likely to prefer the Summit Mattress based on our in-depth testing.

Answer a few questions to find the right mattress for your unique needs
Sleeping Style and Body Weight
Douglas Summit Mattress
Sleeper Type
Side Sleepers
Back Sleepers
Stomach Sleepers
Side Sleepers
Our team agreed that the Douglas Summit Mattress is well suited to side sleepers, particularly those who weigh less than 230 pounds.
In general, side sleepers tend to prefer a softer mattress, as this sleeping position naturally puts additional pressure on the hips and shoulders. Memory foam in the top layer of the Douglas Summit is designed to cushion these sensitive areas, while the Elastex foam and polyfoam support core contribute extra support to help maintain spinal alignment.
Side sleepers on our testing team who weigh less than 230 pounds gave the mattress strong marks, noting that it conformed well to the body and helped the spine settle into a comfortable position. People over 230 pounds may find that their hips and shoulders sink too far into the mattress, which can draw the spine out of a neutral posture.
Back Sleepers
The Douglas Summit is medium firm (6), a firmness level that functions well for most back sleepers. This degree of firmness is simultaneously able to provide cushioning while maintaining stable support under the abdomen and lower back. The memory foam in the Douglas Summit also accommodates the natural curve near the lumbar spine, helping many people avoid back pain.
During our tests, back sleepers under 130 pounds received very good support from the Douglas Summit. Some back sleepers over this weight threshold mentioned that they prefer the firmer feel and added responsiveness of a typical hybrid or latex mattress. These attributes can help ensure that heavier areas, such as the midsection, do not sink too far into the mattress.
Stomach Sleepers
The general consensus during our testing process was that the Douglas Summit is a little too soft for most stomach sleepers. In particular, testers over 130 pounds found that the medium firm (6) feel and foam construction allowed the midsection to sink in significantly, pulling the spine out of alignment and causing some neck and back pains.
A firm mattress is usually considered best for stomach sleepers because it can help keep the spine on an even plane. That said, some testers under 130 pounds did receive sufficient support since these sleepers exerted less pressure on the mattress and did not sink in as far.
Mattress Performance
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.

Douglas Summit Mattress Review Breakdown
The Douglas Summit is a 12-inch foam mattress with three layers inside a specially formulated cover.
Produced using a closed-loop process to minimize waste, the cover contains cooling nanofibers that are designed to reduce heat buildup on the surface of the mattress (). The cover is removable and can be machine-washed on the gentle cycle.
The top layer of the mattress is 2.5 inches of ecoLight cooling gel memory foam. Memory foam contours to the body, helping absorb motion and relieve pressure where it’s most needed. This foam also contains phase change material engineered to absorb or draw in heat as necessary in order to maintain a neutral temperature.
Below the memory foam is a layer made up of 2.5 inches of Elastex foam. This latex-like polyfoam is bouncier, which helps prevent the feeling of being stuck in the bed. This not only allows sleepers to change positions more easily but also works in combination with the memory foam to encourage proper spinal alignment during sleep.
The support core is a 7-inch layer of polyfoam. With an additional inch of this dense foam compared to the Douglas Original, the support core adds sturdiness and cuts down on excess sinkage.
GoodMorning.com manufactures this Canadian mattress using foams that carry the CertiPUR-US label, meaning they conform to independent safety standards regarding harmful chemicals. In addition, the bed’s ecoLight foam is made with a process that uses less carbon than standard memory foam.
On a scale of 1 to 10, in which 10 is the firmest, the Douglas Summit is a 6, which ranks as medium firm. Most sleepers should receive a fairly even balance of spinal support, pressure relief, and comfort on a mattress with this firmness level and overall performance.

Mattress Prices and Sizing
The Douglas Summit is competitively priced relative to other foam mattresses on the market. As with the other Douglas mattresses, the Summit comes in just one firmness option: medium firm (6).
This model is more expensive than its siblings, the 10-inch Douglas Original and the 11-inch Douglas Alpine. All three models have a similar build and the same firmness level. Price-conscious shoppers may prefer the Douglas Original or the Douglas Alpine, but for those who are willing to pay a little extra, the Douglas Summit offers a thicker comfort system and extra cooling features.
In addition to being available in the standard mattress sizes, the Douglas Summit is offered in split king and several RV sizes, including RV bunk small, RV three-quarter, and RV short queen.

Trial, Warranty, and Shipping Policies
Douglas only sells the Summit Mattress within Canada. Customers can buy the mattress online through the Douglas website.
Shipping is free to most Canadian addresses, with an additional charge for delivery to some remote locations. Mattresses are made to order. Once the mattress has shipped, it usually arrives within one to six business days, depending on the location.
The Douglas Summit ships compressed and shrink-wrapped in plastic. Larger sizes are heavy and may require two people to carry to the bedroom.
To unbox the mattress, place it on the bed frame and carefully remove the plastic. The mattress should expand almost immediately, though Douglas recommends waiting at least half an hour before lying on it.
GoodMorning.com does not offer White Glove delivery or old mattress removal.
The Douglas Summit Mattress comes with a 365-night sleep trial, though owners are required to keep the mattress for at least 30 nights before requesting a refund. This break-in period encourages sleepers to give the mattress a fair evaluation before deciding whether to keep it.
The Douglas Summit Mattress must be wrapped in plastic for return. For this reason, GoodMorning.com recommends keeping the plastic from the original packaging until the sleep trial is over. Because most returned mattresses are donated to charity, GoodMorning.com only accepts returns if mattresses are in mint condition.
GoodMorning.com offers a 15-year limited warranty for the original purchaser of a Douglas Summit Mattress. The warranty is prorated, meaning that coverage decreases with time. Return or replacement of a defective mattress is free of charge for the first 10 years. From years 11 to 15, the customer is responsible for covering 25% of the cost.
To qualify for warranty coverage, the mattress must have been unboxed within two weeks of delivery and always used with a suitably supportive foundation as outlined in the full warranty terms.
The warranty covers permanent indentations greater than 2 inches, as well as manufacturing defects in the mattress cover. Mattresses that have been damaged or abused are not eligible for warranty coverage. Changes in comfort preferences or natural softening of the foam over time do not qualify as defects.
GoodMorning.com will repair or replace mattresses that are deemed defective under the terms of the warranty. The company will provide instructions for how to send back the mattress. Customers with a defective mattress may elect to upgrade to a more expensive one by paying the difference in price. Other terms and conditions apply.
