Overall Ratings

Edge support and motion isolation are factored into our overall mattress ratings. These scores are shown in green (scores of 5.0+), yellow (3.0–4.9), or red (2.9 and below). Firmness, bounce, and cooling features are a matter of personal preference and aren’t part of our rating system, so these scores are shown in grey.

Mattress Performance Results

Firmness

Simba 2500 is considered a medium-firm mattress with a score of 6.1/10. Douglas was also categorized as medium-firm with its firmness score of 6.7/10. Both of these mattresses will suit most sleepers, whether they sleep on their side, stomach, or back.

Edge Support

Foam mattresses aren’t typically known for strong edge support compared to their hybrid counterparts. Douglas, however, earned a very good edge support score of 7.8/10.

Simba 2500 also has an above-average edge support score of 6.0/10. While you shouldn’t have any trouble staying on the bed when you lie or sit on the side of either mattress, you may prefer Douglas for a bit more support if you often sit or sleep near the edge of the bed. 

Motion Isolation

If you’re a light sleeper or share your bed with a partner, kids, or pets, you’ll need a mattress with good motion isolation. A mattress that absorbs movement will allow you to get a comfortable and restful night’s sleep.

Douglas earned an excellent motion isolation score of 8.3/10. Simba scored lower but still had a very good score at 7.7/10.

Bounce

Bounce in mattresses is a preference. Some sleepers prefer a bouncier, more responsive sleep surface, while others prefer a lower level of bounce. Simba scored a 3.9/10 for bounce, which is below average for a hybrid. Douglas also has a below-average bounce score of 3.1/10 that is a bit more typical of an all-foam mattress. Both mattresses will suit sleepers looking for a slower response time from their bed. 

Cooling Features

Douglas Original and Simba 2500 both offer cooling features to help sleepers stay cool and comfortable throughout the night. Simba promotes the 2500 mattress’s several cooling features, which earned a cooling features score of 4.0/10. These features include its breathable cover, layers of open-cell and perforated foam, pocketed micro-coils, and graphite-infused foam. Simba 2500 offers these features for $2,199 for a queen size.

In comparison, Douglas Original earned a similar cooling features score of 4.2/10. Its moisture-wicking cover, layer of ecoLight® cooling gel foam, and layer of breathable Elastex® foam provide a similar level of cooling for a lower price of $799 for a queen size.

Mattress Construction

Douglas is a foam mattress containing 3 layers, while Simba 2500 is a hybrid mattress featuring 4 layers. 

Douglas Original Mattress Layers

• Layer 1: The 2″ top layer of the Douglas mattress is made of ecoLight® cooling gel foam. It’s just as durable, comfortable, and body-contouring as memory foam. This layer also has open-cell construction for extra breathability.
• Layer 2: The 2″ middle layer is made of Elastex® foam for extra spring and support. This is a latex-free foam with a similar level of responsiveness and support.
• Layer 3: The 6″ bottom layer is made of motion isolation support foam. This means you’ll hardly feel a thing from the other side of the bed, even if your partner is tossing and turning all night long.

Douglas Original features a machine-washable mattress cover made of polyester, spandex, and plant-based Infinitex™ fibres that draw moisture away from the surface to offset any heat-trapping. The cover materials give it moisture-wicking properties, helping you stay dry and comfortable throughout the night.

Simba 2500 Mattress Layers

• Layer 1: The top layer is 1″ of graphite-infused foam. This layer contours around your body and helps to relieve pressure. The graphite infusion helps to dissipate heat, keeping your sleep cool.
• Layer 2: The second layer is 1″ of micro-coils. These cone-shaped springs are individually pocketed and encased in a layer of edge support foam along the mattress’s sidewalls.
• Layer 3: The third layer is 3.5″ of polyurethane foam that incorporates Simba’s “Edge Lift” technology. This layer is explained as creating more edge support, but Simba doesn’t provide details to explain how it does this.
• Layer 4: The bottom layer is 6.5″ of support foam. This dense foam layer gives the mattress most of its bulk and keeps you from sinking in too deep, and has perforations to increase airflow.

Advertised as being breathable and hypoallergenic, Simba’s mattress cover is made from polyester, polypropylene, and elastane. Despite having a zipper, the cover also isn’t machine washable—you should spot-clean any spills or stains.

Pick the mattress with a cooling, machine-washable cover.

Delivery, Sleep Trial & Returns

Simba 2500 may be ordered directly from Simba Sleep’s Canadian website or via Sleep Country Canada; however, shipping on both sites is handled by Sleep Country. The mattress should reach your doorstep in 3–10 business days, including dispatch and delivery time.

Douglas uses FedEx to ship their mattresses, and ships by ground from Ontario or Alberta. You should receive your Douglas mattress in 2–10 business days, including dispatch and delivery time. Both mattresses ship in a box, with free shipping to most locations in Canada and applicable fees for some orders made to remote locations.

You have a 100-night sleep trial to decide whether to keep Simba 2500. If you decide to return it, you’ll need to bring the mattress back to the store yourself, as Sleep Country doesn’t provide return pickup. Sleep Country also doesn’t offer refunds on returned mattresses, and you can only exchange your mattress for in-store credit minus a $65 exchange fee. If you exchange Simba 2500 for a more expensive mattress, you must pay the price difference. 

Douglas, on the other hand, offers a 365-night sleep trial. This is one of the longest trials available in Canada. Douglas offers free return pickup and will issue a full refund within the sleep trial period if you wish to return the mattress.

Douglas also provides a 20-year warranty, which is longer than the standard industry warranty length. Simba 2500 comes with an average length 10-year warranty, which covers manufacturing defects only. It doesn’t cover normal wear and tear or incidental damage. This warranty is fulfilled by Sleep Country.
