Who the Foxglove Is (and Isn't) For
Most people who walk into our Brantford showroom think they know what firmness they want. They usually say "medium," which is fair, medium is the most common preference, and for good reason. The Foxglove Premium is built for exactly that customer.
It suits side sleepers who need enough give for their shoulder and hip, back sleepers who want support without rigidity, and couples with similar comfort preferences. The 12-inch profile keeps it compatible with most bed frames, platform bases, and adjustable foundations without the sheet-fitting challenges you get from taller models.
The weight sweet spot is roughly 120 to 230 lbs. Below that, medium firmness can feel harder than expected because lighter sleepers don't compress the upper foam layers enough to access the responsive feel underneath. Above 230 lbs, heavier sleepers tend to need a firmer foundation to prevent the hips from sinking out of spinal alignment over time.

If you're a stomach sleeper, the Foxglove is probably not for you. Stomach sleepers generally need firmer support to prevent the lumbar spine from arching downward overnight, and a medium mattress tends to let the midsection sink more than is comfortable for that position over hours at a stretch.
Why Pocket Coils Matter
There are two main coil technologies in mattresses: open coil (sometimes called Bonnell coil) and pocket coil. The Foxglove uses pocket coils, and that's worth understanding before you buy anything.
In an open coil system, the springs are interconnected with metal wire. When you move on one side, that movement travels through the wire connections across the whole mattress. If you sleep with a partner and they roll over at 3 a.m., you feel it. This isn't a dealbreaker for some people, but it's something to know.
How Pocket Coils Work Differently
Pocket coils are individually wrapped in fabric pockets, completely separated from each other. When pressure is applied to one coil, only that coil compresses. The coils next to it stay at their natural height. This does two things: it isolates motion so a partner's movement stays on their side of the bed, and it allows each zone of the mattress to respond independently to your body's contours rather than applying uniform resistance across the surface. For side and back sleepers especially, this means the shoulder area can sink slightly while the lower back receives firmer support, all within the same mattress.
Pocket coil construction is also why hybrids tend to last longer than all-foam mattresses. The coil layer provides a stable, breathable core that doesn't compress permanently over time the way foam can. The foam layers above soften things up, but the structure underneath holds its shape.
In our experience at Mattress Miracle, customers who've owned open coil mattresses and switch to pocket coil often notice the difference immediately, not in some abstract technical way, but in sleep quality and morning back comfort.
The Research Behind Medium Firmness
Medium isn't just a popular choice, it's the firmness level that research consistently validates for the broadest range of sleepers.
What the Science Says About Medium Firmness
A 2021 study published in the Journal of Orthopaedic Surgery and Research found that medium-firm mattresses improved sleep quality and reduced back pain compared to both firm and soft alternatives. Separately, a landmark study in The Lancet involving 313 patients with chronic non-specific low-back pain found that those who slept on medium-firm mattresses reported significantly more improvement in pain-related disability than those on firm mattresses. More recently, polysomnography research published in Nature and Science of Sleep (2025)1 found that medium-firmness mattresses produced fewer sleep-stage transitions and better sleep initiation than softer alternatives, supporting more stable sleep architecture.
The physics make sense: your body isn't a flat plane. You have a shoulder, a waist, and hips, each with different widths and weights. A medium mattress allows the wider parts (shoulder, hip) to sink proportionally while supporting the narrower parts (waist). A mattress that's too firm doesn't allow any of this, creating pressure points at the shoulder and hip. A mattress that's too soft allows the heavier sections to sink too deeply, pulling the spine out of its natural curve.
The 120-230 lb range where medium performs best reflects this: heavier sleepers exert more pressure and need firmer support to prevent the lumbar area from sagging, while lighter sleepers may not engage the support layers fully on a firmer model.
If you're unsure whether medium is right for you, we'd say come in and lie on it. Fifteen minutes on the mattress tells you more than any spec sheet.
Made in Canada: What It Actually Means
The Foxglove is manufactured in Canada by Anderson, Restonic's Canadian production partner. "Made in Canada" isn't just a marketing label here, it has regulatory teeth.
Canadian Manufacturing and What It Means for Your Mattress
Under Canada's Consumer Product Safety Act (CCPSA) and the Mattresses Regulations (SOR/2016-183), Canadian mattress manufacturers must test products to flammability standards during production, not after shipping overseas. Health Canada's 2024 compliance verification confirmed all 14 tested Canadian-made mattresses passed flammability requirements. The foam layers in Restonic's Canadian-built mattresses carry CertiPUR-US certification, excluding ozone depleters, PBDEs, heavy metals, formaldehyde, and VOC emissions over 0.5 ppm. For families in Brantford and across Ontario who want to know what's inside their mattress, that's a meaningful standard to point to.
Restonic runs manufacturing operations across Canada, in Ontario, British Columbia, Quebec, and Alberta. The Canadian production pipeline means shorter supply chains, which generally translates to tighter quality control and faster warranty resolution compared to overseas alternatives. When something goes wrong with an imported mattress, warranty claims often involve complicated logistics. With Canadian-made, the process is more direct.
We're grateful to carry Canadian-made options at Mattress Miracle. It matters to us, and it tends to matter to our customers once they understand the difference.
Our Honest Assessment
The Foxglove does what a well-built medium hybrid should do. The pocket coils provide responsive support that adjusts to different positions, the foam layers add surface comfort without trapping heat the way dense memory foam can, and the 12-inch profile is versatile enough for most bedroom setups.
At the current price point, this is a legitimate mattress, not an entry-level throw-away. Anderson's manufacturing quality shows in the edge support and the consistency of the comfort layers. It won't feel like you're sleeping on a budget buy.
That said, it's not the most feature-rich mattress in our lineup. There's no specialty cooling layer, no luxury textile cover, and the foam layers are straightforward high-density rather than the latex or gel-infused options you'll find in upper-tier models. If temperature regulation is your primary concern, we'd point you toward something with more cooling engineering. If pressure relief for heavier sleepers is the priority, the firmer options in our mattress collection might serve you better.
The Foxglove is a confident "yes" for someone who wants quality construction, medium comfort, and Canadian manufacturing without paying for features they don't need.
Foxglove vs. the Restonic Revive Series
We carry several Restonic models, and customers sometimes ask how the Foxglove compares to the Restonic Revive series.
Key Differences at a Glance
- Cover: The Revive uses hand-tufted covers with wool, Talalay latex, and copper infusion. The Foxglove uses quality fabric over standard foam, solid, but simpler.
- Comfort layers: Revive incorporates copper-infused Talalay latex and specialty foam blends. The Foxglove uses high-density foam, less complex, less expensive.
- Profile: The Revive Tiffany Rose and Jasmine are 14-15", the Foxglove is 12".
- Price gap: Significant. The Foxglove is the more accessible choice.
- Who wins: If budget is the primary constraint, the Foxglove. If you want longevity advantages of latex, wool moisture management, and copper antimicrobial properties, the Revive series.
Neither choice is wrong. They're different products for different priorities. The Foxglove is a mattress that does its job well and costs less. The Revive is a mattress with more sophisticated materials and a longer comfort lifespan, at a premium price. We'll help you find the right fit in person, there's no pressure either way.
Frequently Asked Questions
Is the Foxglove Premium a good mattress for back pain?
For many people with back pain, yes, medium firmness is the most commonly recommended starting point by chiropractors and physiotherapists. Research published in The Lancet found that medium-firm mattresses outperformed firm mattresses for chronic low-back pain. That said, back pain is individual. If your pain has a specific cause, a herniated disc, spinal stenosis, or joint issues, we'd recommend consulting your doctor or chiropractor before choosing firmness. The Canadian Chiropractic Association3 notes that roughly 1 in 8 Canadians experiences chronic back problems, and mattress support is one factor among many in managing it.
What's the difference between pocket coil and open coil mattresses?
Open coil springs are connected by a wire frame, meaning movement on one side of the bed travels through the whole mattress. Pocket coils are individually wrapped in fabric and respond independently to pressure. This makes pocket coil mattresses much better at isolating motion (a partner's movement stays on their side) and allows each part of the mattress to conform to your body contours separately. For most sleepers, pocket coil is the better choice.
How does the Foxglove's 12-inch height affect sheet selection?
You'll want fitted sheets with a pocket depth of at least 12 inches, ideally 13-14 inches if you use a mattress protector. Standard sheets are often labeled as fitting mattresses up to 12 inches, so double-check the depth before purchasing. Sheets with deep pockets or stretch fabric are the safest bet and are widely available at most linen retailers.
Can the Foxglove Premium be used on an adjustable base?
Yes. Pocket coil hybrids are generally compatible with adjustable bases because the individually wrapped coils flex smoothly with the base's articulation. A 12-inch profile is also within the typical height range that adjustable bases are designed to support. If you're pairing it with an adjustable foundation, mention this when you call or visit, we can confirm compatibility with the specific base you have in mind.
