Product Details
Kingsdown Studio Acton is a 5-layer innerspring mattress that stands 10″ tall. It features a zoned pocket coil system and a thick foam encasement, which provides excellent edge support. In third-party engineer testing (commissioned by us), it scored one of the highest bounce ratings we’ve recorded, giving it a very responsive feel.
Acton is marketed as a firm mattress. However, according to third-party testing (commissioned by us), it falls under the medium-firm category. The relatively thin layers of foam, polyester, and wool-blended batting allow you to interact more directly with the coils. You may not enjoy this feeling if you prefer a more cushioned and pressure-point relieving sleep surface.
In comparison, competing luxury hybrid mattress Logan & Cove Choice comes with more advanced cooling and comfort features for a lower price of just $999 for a queen size, compared to $1,399 for Kingsdown Studio Acton. Logan & Cove has 5,800+ reviews and offers a 365-night sleep trial, a 15-year warranty, and a free bedding bundle with your purchase.

Delivery, Sleep Trial & Returns
The Kingsdown Studio Acton mattress is exclusively available at Sleep Country Canada. Sleep Country provides free shipping for orders over $75 to most Canadian locations, with typical delivery times of 3–5 business days. For customers in Newfoundland and Labrador or the Canadian Territories, shipping takes 7–10 business days and costs $120.
Your mattress will arrive fully expanded. After your mattress arrives, you’ll have 100 nights to decide if it’s the right fit for you. This sleep trial length is standard for the mattress industry.
However, if you decide to return the mattress during the trial period, you won’t receive a refund. Instead, you’ll have to exchange the mattress for in-store credit after paying a $65 exchange fee. If you exchange for a less expensive model, any remaining balance must be spent on other Sleep Country products. And if you choose a more expensive mattress, you’ll need to pay the difference.
Sleep Country also doesn’t provide home pickups for exchanges. This means you’ll need to transport the mattress back to the store yourself—even if you bought it online and there isn’t a Sleep Country location near you.
The Kingsdown Studio Acton mattress includes a 10-year warranty through Sleep Country. The warranty only covers manufacturing defects and normal wear and tear, not including transportation or delivery damage. Additionally, the warranty allows for size variations of up to 3/4″, which could affect how your sheets fit.
Kingsdown’s manufacturer warranty can vary based on the specific code on your mattress tag. This requires cross-referencing with their warranty documentation. Acton’s law label said it falls under warranty code A, which is a 10-year warranty with no-charge coverage during the total limited warranty period. Both the Sleep Country and Kingsdown warranty lengths are standard for the mattress industry.
Get Logan & Cove Choice and enjoy a 365-night trial with free returns.

Kingsdown Mattress Construction
Kingsdown Studio Acton is a 10″ innerspring mattress. It contains 5 layers of polyester and wool-blend batting, foam, and metal coils, surrounded by a 3″ sidewall of high-density foam. It’s important to note that the top layers of batting and foam are quite thin, which allows for noticeable sinkage so you can feel the coil system beneath. The foam used in the mattress isn’t CertiPUR-US® certified.
- Layer 1: The first layer is 0.5″ of polyester and wool-blend batting. According to Kingsdown, this layer is designed to help remove excess heat from the body.
- Layer 2: The second layer is 0.5″ of polyurethane foam, which may be infused with gel and helps relieve pressure points and provide some contouring.
- Layer 3: The third layer is 0.5″ of polyurethane foam. Like the foam layer above, which seems to have the same composition, its intended use is to help provide temperature-regulation, contouring, and pressure-point relief.
- Layer 4: The fourth layer is 0.5″ of polyester and wool-blend batting. Like the first layer, this thin layer of material is intended to regulate temperature.
- Layer 5: The bottom layer is a 7″ zoned coil system designed to support the mattress’s overall structure.
Studio Acton’s mattress cover is made from a viscose and polypropylene foam blend, which offers a hypoallergenic and breathable sleep surface. Kingsdown advertises that the mattress contains wool-blend batting to help absorb body heat and offer antimicrobial benefits.

MattressReviews.ca commissions licensed third-party engineers and uses public data to rate mattresses on over 40 criteria.
This allows us to accurately rate and compare the performance of the mattresses reviewed on this website. Engineer independence and operating standards help ensure their results remain unbiased, valid, and reliable. Each mattress was evaluated using the same strict mattress testing methodology to protect the overall integrity of the results. The full report has been given the official stamp of approval from an APEGA-certified engineer operating under a strict ethical code of conduct.
Mattress testing conducted outside of this professional standard poses a greater risk of validity errors or reviewer bias.

6.7 /10
Firmness
Despite being advertised as a firm mattress, Kingsdown Studio Acton scored 6.7/10 for firmness in third-party engineer testing (commissioned by us). This places the mattress in the medium-firm category. However, because the comfort layers are quite thin, you will most likely sink into the metal coil system and feel the coils beneath your body.
(Want a mattress that’s even more supportive while adding extra comfort? Consider Logan & Cove Choice with its thicker comfort layer and firmness score of 6.9/10.)

9.7 /10
Edge Support
Kingsdown Studio Acton scored 9.7/10 for edge support. This is an excellent score, likely due to the mattress’s thick high-density foam sidewalls and layer of pocket coils. You should feel very well supported while sitting on the edge of the bed or lying farther away from the middle of the mattress.
7.1 /10
Motion Isolation
Studio Acton scored 7.1/10 for motion isolation, which is above average for a hybrid mattress. You won’t be able to feel everything your partner does when they move around, but bigger movements may still be noticeable.
(Searching for a mattress with greater motion isolation? You may prefer Logan & Cove Choice with its motion isolation score of 7.5/10.)
8.7 /10
Bounce
Studio Acton scored 8.7/10 for bounce. This is very high for any mattress and is one of the highest scores we’ve ever recorded in third-party engineer testing (commissioned by us). While it may be easy to shift positions on this mattress, light or sensitive sleepers may find it too responsive for their needs.
(Need a mattress with less bounce? With a lower bounce score of 5.8/10, Logan & Cove Choice makes it easy to change positions without waking anyone up.)

3.3 /10
Cooling Features
Kingsdown Studio Acton isn’t marketed as a cooling mattress, but it offers a few cooling features to help you stay cool at night. This mattress earns points for its:
- Breathable viscose and polypropylene foam cover
- Layers of polyester and wool-blend batting to draw excess heat away from your body
- Layers of cooling gel foam for heat dissipation
- Layer of pocket coils for breathability and airflow
If you want a hybrid mattress with more cooling features for a refreshing night’s sleep, consider Logan & Cove Choice instead. Its top cover is designed with cooling nanofibres, breathable hollow fibre, and gel-infused foam, while its internal layers include more gel foam and individually wrapped steel pocketed coils.
These cooling features come at a much lower price of $999 for a queen size, compared to $1,399 for Kingsdown Studio Acton.

They’re typically sold at a higher price point than many other mattresses.
Is Kingsdown a good mattress?
Kingsdown Studio Acton performed well in third-party engineer testing (commissioned by us) for motion isolation and edge support.

It also earned a lower cooling features score and has shorter sleep trial and warranty periods while being more expensive than comparable mattresses like Logan & Cove.

How long does a Kingsdown mattress last?
According to experts, a good mattress should last 7–10 years. However, this can vary depending on the materials used in the mattress’s construction and how frequently it is used. There’s no strict rule, but if you notice visible sagging, lumps, or a decline in comfort and support, it may be time to replace it. Regular maintenance and proper care can help extend a mattress’s lifespan.
