Douglas Original Mattress Review

This mattress scores 6/10 on our firmness scale — positioned as medium firm, though in practice it sleeps considerably softer. As a 127lb woman, I observed deeper sinking on the Douglas than on similar mattresses, like the Endy Original. The foam composition leans toward the soft end of medium firm, which may disappoint sleepers expecting a genuinely firm sleeping surface.

If you're like me and prefer a firm mattress, consider Endy or Silk & Snow, as both offer firm versions of their all foam mattress with more reliable proper spinal alignment and balanced support. The Douglas Summit Mattress offers a somewhat firmer profile within the Douglas lineup, but even that comes with caveats compared to the consistently firm options from Canadian competitors.

Some of the Douglas Original customers have pointed out that the mattress is not as cooling as they hoped. We retested the Douglas Original for heat dissipation in Spring 2026, and found that it retained more heat after 30 minutes of use compared to similar mattresses. The cooling gel foam layer and CoolSense® mattress cover provide some heat retention management, but fall short of delivering the consistent cooling technology performance advertised.

The heat retention issue is compounded by the traditional memory foam Elastex® middle layer, which — like most traditional memory foam — limits airflow through the foam structure. For hot sleepers, the Douglas Original is unlikely to deliver the better sleep experience they're seeking. If you sleep hot, this may not be the right choice for you. We'd recommend hot sleepers consider the Endy Original, Silk & Snow S&S, or The Casper instead — all of which feature more advanced cooling technology and scored meaningfully higher in our heat dissipation testing.

The entire Douglas mattress range offers a broadly similar construction, with the Douglas Original featuring slightly less foam depth than its pricier alternatives like the Douglas Summit. Personally, I do not like the feeling of being enveloped or cradled on a mattress, and when I slept on the Douglas, I could certainly relate to common customer complaints about how soft this mattress was. The foam layers create a comfortable bed experience for lighter sleepers, but the lack of perfect bounce and balanced support makes this a difficult recommendation for anyone seeking a genuinely responsive sleep surface.

Memory foam mattresses are usually praised for motion isolation — however, the Douglas Original did not particularly excel in this area. During tests in our sleep lab, there was significant movement in the water vessel when the sleep tester got in and out of bed. If you share your bed with someone, you may want to look at the Endy Original, which delivers superior motion isolation in our testing by comparison — meaning you can barely feel a partner's movements during the night.

The Douglas's foam layers absorb some motion transfer, but not to the level that most sleepers sharing a bed would find satisfactory. This was a consistent finding in our testing and aligns with a meaningful volume of negative customer reviews about motion transfer on this mattress.

As mentioned, the enveloping feel of memory foam is not to everyone's liking — and the Douglas Original exemplifies this. When testing, I found I sank into the foam and wasn't able to move as easily across the mattress surface as I could with The Endy or The Casper. The Douglas Original also lacks perfect bounce, limiting its responsiveness significantly.

When we dropped a 5lb ball onto the mattress, it only bounced once — a few centimetres above the surface — before settling. This is a useful indicator of how the mattress will respond to nighttime movement: most sleepers, especially combination sleepers, will find repositioning on the Douglas more effortful than on competing foam mattress options. The Douglas Summit does improve somewhat on this front, but the Douglas Original in its current form is a meaningful step behind the standard set by Endy, Casper, and Silk & Snow.

The Douglas Original's edge support wasn't as strong as I hoped. There was approximately 6–7″ of sinkage at the perimeter, taking me all the way down to the foundational support foam, and causing an unbalanced feel. For a foam mattress at this price point, this level of edge support performance is disappointing — especially when other brands like Endy and Silk & Snow deliver meaningfully stronger edge support at comparable prices.

The weak edge support also limits the usable sleep surface of the mattress, as sleeping or sitting near the perimeter of the bed risks an uncomfortable, unstable experience. This is a recurring theme in customer reviews of the Douglas Original, and our testing confirmed it is a genuine and consistent limitation — not an isolated incident.

In our Spring 2026 tests, the Douglas Original had an off gassing-like smell that persisted for 19 days. We did not measure VOC emissions directly, so the mattress may have stopped off gassing earlier — but if you're sensitive to smell, this is a meaningful consideration when planning your first sleep on a new mattress. Placing the mattress in a well-ventilated room and using a mattress protector immediately can help manage this. By comparison, off gassing on Canadian-made alternatives like Endy dissipates far more quickly in our testing.

The Douglas Original scores a middling 5 out of 10 for bounce, which is unsurprising given it's a basic all-foam construction: a gel-infused memory foam comfort layer over a polyfoam transition layer and polyfoam base. Foam of this type absorbs energy rather than returning it, so there's little spring to speak of here. That means less effort required to isolate motion, but it also means the mattress can feel slow and heavy to move on — an issue for anyone who shifts positions often through the night. This is a fairly typical result for an entry-level all-foam mattress, and not a category where the Original differentiates itself.
