Quick Answer: Polysleep and Restonic are both genuine manufacturers, not just brands that outsource production. Polysleep makes its own foam in Montreal. Restonic's 13 cooperative factories build their own mattresses across North America. The key difference is engineering philosophy: Polysleep builds all-foam mattresses starting around $899 CAD. Restonic builds hybrids with 1,222 coils in the ComfortCare queen at $1,619 CAD. Both are honest companies that stand behind what they build.

Two Companies That Build Things
Most mattress brands in the 2020s are marketing companies. They design a spec sheet, contract a factory to build it, slap their logo on the cover, and spend most of their budget on Instagram ads and affiliate review deals. The mattress arrives in a box that says one brand, but it rolled off a production line shared with a dozen others.
Polysleep and Restonic are different. Both actually manufacture.
Polysleep operates its own factory in Montreal where it produces its own foam. That is remarkably rare. Most bed-in-a-box brands buy pre-made foam from suppliers like Carpenter Co. or FXI and layer it into a cover. Polysleep formulates and pours its own foam, including its ISO-certified antimicrobial medical foam, in-house. They control the chemistry from liquid to finished mattress.
Restonic's 13 independently owned factories across North America each build Restonic mattresses from raw materials through finished product. The cooperative owns the intellectual property, the Marvelous Middle zoned support technology, the engineering specifications. The factories own the production. Each facility invests its own capital and employs its own team.
When you compare these two brands, you are comparing two companies that can actually tell you what is in their mattress because they put it there themselves. That is a starting point of trust that most mattress comparisons lack.
Foam vs Coils: The Fundamental Choice
Before comparing specific models, understand the fundamental engineering difference: Polysleep builds all-foam mattresses. Restonic builds hybrids with individually wrapped coils.
This is not a quality distinction. It is a physics distinction. Each approach creates a different sleep experience, and your body will prefer one over the other.
How Each System Supports You
All-foam (Polysleep): Foam compression creates a cradling effect. Your body sinks into the mattress and the foam wraps around your contours. Support comes from the density gradient between softer comfort layers and firmer base foam. Motion transfer is minimal because foam absorbs movement locally. The trade-off: foam retains heat more than coils, and it compresses faster over time under sustained load.
Hybrid coils (Restonic): Each of the 1,222 individually wrapped coils acts as an independent suspension point. Your body weight distributes across hundreds of springs, each compressing to the exact degree demanded by the weight above it. Air flows freely through the coil system. The trade-off: more motion transfer than foam (though individually wrapped coils minimize this), and the mattress feels bouncier, which some sleepers find disruptive.
A 2019 systematic review in Sleep Medicine Reviews found no universal superiority of either type. Foam performed better for lighter sleepers who favoured side sleeping. Hybrids performed better for heavier sleepers and those who changed positions frequently during the night (Caggiari et al., 2019).

Polysleep's Innovation
Credit where it is due: Polysleep invests in material science in ways that most mattress brands do not. Their Zephyr 2.0 is a showcase of foam engineering.
ISO-certified antimicrobial foam: Polysleep's proprietary foam formulation resists bacteria and dust mite infestations at the material level, not through a surface treatment that washes off over time. This is genuinely useful for allergy sufferers and is a meaningful differentiator from brands that add antimicrobial covers over standard foam.
Nanobionic technology: The Zephyr's cover uses mineral-infused fibres that redirect your body's infrared heat back into your muscles, which Polysleep claims aids recovery. The science behind far-infrared textile technology is emerging. Some studies in Journal of Photochemistry and Photobiology show modest benefits for tissue recovery, though the sleep-specific evidence remains limited (Vatansever & Hamblin, 2012).
KulKote phase-change material: This absorbs excess body heat when you are warm and releases it when you cool down, creating a more stable sleep temperature. Phase-change materials are well-established technology used in aerospace and sports equipment.
Polysleep's engineering ambition is genuine. They are not just stacking commodity foam in a cover. They are formulating materials with specific performance goals. For an all-foam mattress, this is as good as the category gets in Canada.
Restonic's Engineering
Restonic's approach is less flashy but equally intentional. Rather than inventing new materials, Restonic has spent decades refining how coils and foam work together.
Marvelous Middle: The centre third of the mattress, where roughly 60% of body weight concentrates, receives additional structural reinforcement through zoned coil architecture. This is not marketing language. It is mechanical engineering. Heavier body segments (hips, lower back) get firmer support while lighter segments (shoulders, legs) get softer response.
1,222 individually wrapped coils: Each coil operates independently, compressing only under the weight directly above it. When you and a partner have different body weights, each side of the mattress responds to its own load without transferring force across the surface.
Natural airflow: The coil system creates thousands of air channels through the mattress interior. This provides passive cooling without the need for phase-change materials or gel infusions. Coil-based mattresses are inherently cooler than all-foam mattresses because air circulates where foam would otherwise trap heat.
Brad, Owner, 40+ years of experience: "I have a lot of respect for what Polysleep does in Montreal. Making your own foam is hard, and they do it well. But the reason I carry Restonic instead of an all-foam brand is physics. Foam compresses. Coils bounce back. Over ten years, 1,222 individually wrapped coils maintain their support characteristics better than foam layers, regardless of how good the foam formula is. That is not opinion. That is material science."
How Your Body Weight Decides
This might be the most useful section for making your actual decision. Your body weight, more than any brand preference, determines which engineering approach will serve you better.
Weight-Based Guidance
Under 150 lbs: Both types work well. Lighter sleepers may prefer Polysleep's foam contouring because their body weight is not enough to fully compress the foam, creating a gentle cradling effect. The Restonic will feel firmer and more supportive at this weight.
150-220 lbs: This is the range where hybrid construction starts to show advantages. The coils provide responsive pushback that prevents the "hammock effect" where foam compresses too deeply in the middle. Restonic's Marvelous Middle addresses this specifically.
Over 220 lbs: Hybrid mattresses are generally recommended by sleep researchers for heavier sleepers. The coil system distributes weight more effectively and maintains support characteristics longer under sustained heavy load. All-foam mattresses in this weight range tend to develop permanent impressions sooner (Verhaert et al., 2011).
Dorothy, Sleep Specialist: "When couples come in and one partner weighs 140 pounds and the other weighs 220, the foam vs coil question answers itself. Each coil in the Restonic responds independently. The lighter partner gets gentle support. The heavier partner gets firmer pushback. Foam cannot do that because it compresses uniformly across its surface. It is not a fault of the foam. It is how foam works."
The Buying Experience
Polysleep: Online with Canadian Retail Partners
Polysleep sells primarily online through polysleep.ca with free shipping across Canadian provinces. The Origin 2.0 comes with a 100-night trial (returns accepted after 45 nights of use). Some Polysleep models are also available through select Canadian retailers and on Amazon.ca.
The 100-night trial is reasonable, though shorter than some competitors' 365-night offers. Polysleep's approach is transparent: try it, and if it does not work, return it. No gimmicks.
Restonic: Showroom with Full Service
Restonic sells through authorized retailers where you can test mattresses in person. At Mattress Miracle in Brantford, that includes hands-on guidance from sleep specialists, side-by-side model comparisons, and delivery with white glove setup and old mattress removal.
The trade-off is that you need to visit a store. There is no online order option with home trial. What you gain is the confidence of having physically tested the mattress and spoken with someone who can assess your sleeping position and body type.
Two Good Choices for Canadian Buyers
This comparison is unusual in our series because both brands deserve genuine respect. Polysleep is building innovative products in Montreal with real manufacturing expertise. Restonic is building proven products through a cooperative that has operated since 1938. If you are in Brantford and want to feel what a hybrid with 1,222 coils offers compared to an all-foam mattress, visit our showroom. If you prefer the online model with a trial period, Polysleep is a brand we would not discourage you from trying.

Does Polysleep make a hybrid mattress with coils?
Polysleep's primary models (Origin 2.0 and Zephyr 2.0) are all-foam mattresses. The Sierra model includes pocketed coils in its support core. Polysleep's expertise is in foam formulation, including their ISO-certified antimicrobial foam manufactured in-house in Montreal. If you specifically want a coil-based hybrid, Restonic's ComfortCare offers 1,222 individually wrapped coils.
Is Polysleep really made in Canada?
Yes. Polysleep manufactures its own foam and assembles its mattresses in Montreal, Quebec. They are one of the few Canadian mattress brands that produce their own foam in-house rather than sourcing from third-party suppliers. This gives them control over foam formulation and quality that most competitors lack.
Which lasts longer, foam or hybrid?
Generally, hybrid mattresses maintain their support characteristics longer than all-foam mattresses, particularly for sleepers over 180 pounds. Individually wrapped coils resist permanent compression better than foam layers over time. However, foam longevity depends heavily on density, and Polysleep's proprietary formulations may perform better than commodity foams. Expect 7-10 years from either type with proper care.
Which sleeps cooler?
Restonic's hybrid design is inherently cooler because air circulates freely through the coil system. Polysleep addresses foam's natural heat retention with technologies like KulKote phase-change material and GelFlex Plus cooling in the Zephyr 2.0. Both approaches work, but the coil system provides passive cooling without relying on material additives.
