Quick Answer: Pocketed coils outperform continuous coils for motion isolation and body contouring. Each pocketed coil is individually wrapped and moves independently. A pocketed coil mattress with 1,000+ coils in a queen is the benchmark for quality. "Orthopedic" is not regulated in Canada and means nothing specific without coil details.

Coil type is one of the most important and least explained parts of mattress shopping in Canada. Most retailers focus on comfort layer materials (foam, latex, pillow top) while the coil system, which determines how long the mattress holds its shape and how well it supports you, gets listed as a number in small print. This guide covers what those numbers mean and how coil types actually differ in use.
The Three Main Coil Types Explained
Three coil systems appear in Canadian mattresses sold today:
Pocketed coils (also called individually wrapped or Marshall coils): Each coil is individually wrapped in a fabric pocket. Because the pockets are separate, each coil compresses independently. This allows the mattress to contour to body shape without the adjacent coils pulling down. Pocketed coils are the standard in premium mattress construction and are what all Restonic models use.
Continuous coils (Leggett and Platt LFK system): A single continuous wire is bent into multiple coils in a row, then connected to other rows. The coils are linked and move together to some degree. Continuous coil mattresses are less expensive to manufacture and are structurally durable, but the interconnected coils transfer motion across the bed surface more than pocketed systems.
Offset coils (Bonnell offset): A modification of the traditional Bonnell coil with an hourglass shape. Adjacent coils are linked by helical wires at the top and bottom. Offset coils provide better contouring than continuous coils due to their hinge-like connection, and are used in some mid-range mattresses as a cost-effective alternative to pocketed coils.
| Property | Pocketed | Continuous | Offset |
|---|---|---|---|
| Motion isolation | Excellent | Poor to moderate | Moderate |
| Body contouring | Excellent | Moderate | Good |
| Durability | Excellent | Good (one-wire resilience) | Good |
| Cost | Higher | Lower | Middle |
| Common in | Mid to premium range | Budget to mid range | Mid range |

Pocket Coil vs Continuous Coil: What Changes Day to Day
The difference between pocketed and continuous coil mattresses is most noticeable in two situations: sleeping with a partner, and sleeping on your side.
Partners and motion transfer: If one person gets up in the night or changes positions frequently, a continuous coil mattress transfers that movement to the other side of the bed. Pocketed coils isolate the movement to the compressed area. For couples, this is the single most impactful coil choice. Customers who come into our Brantford showroom often describe "feeling every move" on their current mattress, and that is almost always a continuous coil bed.
Side sleeping and pressure points: Side sleepers put concentrated pressure on the hip and shoulder contact points. Pocketed coils allow those specific coils to compress more deeply without pulling adjacent coils down, which distributes pressure more evenly. Continuous coil systems compress as a unit, which provides less targeted relief at pressure points.
Edge support: Quality pocketed coil mattresses often have reinforced perimeter coils at the edge. This maintains a usable sleeping surface to the very edge of the mattress and prevents the "rolling off" sensation that comes from soft perimeter coils. Ask specifically about edge support coil reinforcement when shopping.
Talia, Showroom Specialist: "We do a simple demonstration in the showroom. I put a glass of water on one side of a pocketed coil mattress and press down hard on the other side. The water doesn't move. Do the same on a continuous coil mattress and the water splashes. People understand immediately why it matters for sleeping with a partner."
What "Orthopedic Mattress" Actually Means in Canada
"Orthopedic" is not a regulated term in Canada for mattresses. Health Canada does not certify mattresses as orthopedic, and there is no standard definition of what an orthopedic mattress must contain or do. Any mattress manufacturer can label their product as orthopedic regardless of construction.
In practice, the term is typically used to market one of the following:
Firmer mattresses: The most common use. "Orthopedic" often means firmer than average, based on the older (and now somewhat outdated) clinical guidance that firm mattresses are better for back pain. More recent research, including a 2003 study in The Lancet by Kovacs et al., found medium-firm mattresses reduced chronic low back pain more effectively than firm mattresses in a randomised trial.[1]
Higher-density foam: Some manufacturers use orthopedic to indicate a higher foam density than standard, which does provide longer durability and firmer support.
Marketing language: Some products use the word orthopedic with no material difference from comparable non-labelled products.
The practical advice: ask for coil count, foam density, and whether there is any clinical testing or certification behind the orthopedic claim. If the retailer cannot answer those questions, the label is marketing language.
Natural vs Orthopedic Mattress: Different Questions
Buyers who compare a natural mattress to an orthopedic mattress are usually comparing the wrong things. Natural refers to material sourcing (latex, wool, organic cotton). Orthopedic refers to a support or firmness characteristic. These are independent properties.
A natural material mattress can be orthopedic in its support characteristics. A natural Dunlop latex core is firm and provides strong spinal alignment. A natural wool comfort layer over a pocketed coil base can be softer in the comfort layer while the coil base provides the support firmness. Conversely, a synthetic foam mattress labelled orthopedic can be legitimately firm and supportive.
The question is not natural versus orthopedic. The question is what combination of comfort and support does this specific mattress provide, and what materials achieve it. See our eco-friendly mattress guide for a detailed breakdown of natural material certifications.
Mattress Firmness and Back Pain Research
The clinical evidence on mattress firmness for back pain has shifted over the past two decades. A landmark randomised controlled trial by Kovacs et al. published in The Lancet in 2003 found that medium-firm mattresses were more effective than firm mattresses for reducing chronic non-specific low back pain and disability. A later systematic review in Sleep Medicine Reviews by Radwan et al. (2015) found medium-firm mattresses most consistently associated with both comfort and spinal alignment.[1][2] "Orthopedic" mattresses marketed as extra-firm may not align with this research for all back pain presentations.
Coil Counts: What the Numbers Mean
Coil count alone does not determine mattress quality, but it correlates with contouring ability and durability when comparing mattresses of the same construction type. For a queen-size pocketed coil mattress:
| Coil Count (Queen) | Assessment |
|---|---|
| Under 600 | Below standard for quality pocketed coil. Often continuous or offset coils. |
| 600-900 | Adequate for entry-level pocketed coil. Limited contouring. |
| 900-1,100 | Mid-range quality. Reasonable for single sleepers or lighter builds. |
| 1,100-1,400 | Quality range for most buyers. Good contouring and durability. |
| 1,400+ | Premium. Better contouring for heavier builds or very active sleepers. |
Important caveat: a very high coil count achieved by using thinner-gauge wire can produce lower durability than a moderate count of heavier-gauge coils. Ask for the coil gauge (wire thickness) alongside the count when comparing mattresses. Lower gauge numbers mean thicker wire, generally more durable.
Restonic Coil Specs at Mattress Miracle
| Model | Size | Price | Coils | Coil Type |
|---|---|---|---|---|
| ComfortCare | Queen | $1,619 | 1,222 | Pocketed |
| ComfortCare | King | $2,051 | 1,440 | Pocketed |
| Revive Reflections ET | Queen | $1,395 | 1,200 | Pocketed |
| Luxury Silk and Wool | Queen | $1,395 | 884 zoned | Pocketed (zoned) |
| Revive Tiffany Rose/Jasmine | Queen | $1,995 | 1,188 | Pocketed |
| Revive St Charles/Elizabeth | Queen | $2,150 | 1,188 | Pocketed |
All Restonic models use individually wrapped pocketed coils made in their Hamilton, Ontario facility. The ComfortCare king's 1,440 coils is the highest count in the line, which makes it our top recommendation for heavier couples or buyers who are used to sleeping in a hotel bed and want that level of support at home.
The Luxury Silk and Wool's 884-coil zoned system uses different coil tensions across the mattress zones (firmer under the lumbar and hip areas, softer under the shoulders) rather than uniform coil count. This is a different approach from high-count uniform coils and suits buyers who want targeted zone support rather than maximum coil count.
Brad, Owner, 40+ years of experience: "When I started in this business, pocket coils were a premium feature. Now they are the standard for any mattress worth buying. What people don't often think about is coil gauge. A 1,200-count mattress with 14-gauge steel is a different product than 1,200-count with 17-gauge steel. We specify gauge on our Restonic line because it matters to how long the mattress holds its shape."
Pocketed coils vs continuous coils? Mattress Miracle at 441½ West Street in Brantford carries both types so you can feel the difference in person. Our Restonic ComfortCare uses 1,222 individually wrapped pocketed coils, which means each coil responds independently to your body. Brad can explain how coil types affect motion transfer, durability, and edge support. Most customers are surprised by the difference when they lie on both. Call (519) 770-0001.

Are pocket coils worth the extra cost over continuous coils in Canada?
For most buyers, yes. The motion isolation difference is significant enough that couples who share a bed almost always sleep better on pocketed coil mattresses. The contouring advantage also means fewer pressure points, which matters over an 8-hour sleeping period. The price gap between pocketed and continuous coil mattresses at equivalent quality levels has narrowed considerably over the past decade, making pocketed coils accessible in most budget ranges above $800 for a queen in Canada.
How many coils should a good queen mattress have in Canada?
For a pocketed coil queen mattress, 1,000 to 1,400 coils is the quality range for most buyers. Above 1,000 coils, you generally see better contouring and pressure distribution. The exact count matters less than the coil type (pocketed vs continuous), wire gauge, and perimeter edge support construction. Ask for all three specifications when shopping, not just the headline coil count.
Is an orthopedic mattress actually better for back pain in Canada?
"Orthopedic" is not a regulated or clinically defined term for mattresses in Canada. The evidence for very firm mattresses being best for back pain has been revised by more recent research favouring medium-firm mattresses. If you have specific back pain concerns, focus on a mattress that provides consistent spinal alignment in your primary sleeping position rather than one labelled orthopedic. A sleep specialist or physiotherapist can provide advice specific to your condition.
What is a continuous coil mattress best suited for?
Continuous coil mattresses provide durable, even support at a lower price point. They are best suited for single sleepers who do not have significant pressure point concerns, guest rooms, or buyers on a tight budget who are not sharing a bed with a restless partner. The motion transfer limitation is less relevant when sleeping alone. For children's beds or secondary guest mattresses, a quality continuous coil option at a lower price can be practical.
