Quick Answer: A good queen mattress should have at least 800 pocketed coils, with the sweet spot between 1,000 and 1,400. Above that, returns diminish sharply. Coil type (pocketed vs Bonnell), wire gauge, and comfort layers matter as much as count. At Mattress Miracle in Brantford, our range spans 690 to 1,440 coils across models from $549 to $2,489.

The Coil Count Marketing Myth
Walk into most mattress stores and one of the first numbers you will hear is coil count. "This model has 1,200 coils." "Our premium line has 2,000 coils." The implication is always the same: more coils equals a better mattress.
That is not wrong, exactly. But it is not the whole truth either. And the gap between those two things is where a lot of marketing lives.
Coil count is one variable among several that determines how a mattress supports your body. It interacts with coil type, wire gauge, coil height, comfort layer thickness, and the overall construction of the mattress. Isolating coil count as the primary quality indicator is like judging a car by its horsepower alone. It tells you something, but not enough to make a good decision.
Brad, Owner, 40+ years of experience: "When I started selling mattresses, the Bonnell coil was standard and a queen had maybe 300-400 coils. Today, with pocketed coil technology, we routinely see 1,000-1,400 in a queen. The numbers went up because the coils got smaller and individually wrapped, not because someone discovered a magic threshold. I have seen $600 mattresses with 1,200 coils that wear out in three years, and $1,000 mattresses with 900 coils that last a decade. The count alone does not tell you what you need to know."
A study published in the Journal of Manipulative and Physiological Therapeutics examined mattress coil spring fatigue and weight-bearing support, finding that coil quality and construction design influenced long-term support characteristics more than coil quantity (Buettner et al., 2022). The research measured how coils degrade under repeated loading and found that wire gauge and tempering quality were stronger predictors of durability than the number of coils in the system.
Coil Types: What the Shape Tells You
Before we talk about how many coils you need, you need to know what kind of coils you are counting. The type matters at least as much as the number.
Bonnell Coils
The oldest and simplest design. Hourglass-shaped springs connected to each other with helical wire. When you press on one coil, the surrounding coils move with it. This creates a responsive, bouncy feel but transfers motion across the surface. If your partner rolls over, you feel it.
Bonnell coil mattresses are the most affordable to manufacture. You will find them in budget models, often advertised with high coil counts. A mattress with 1,500 Bonnell coils sounds impressive until you understand that the connected design means those 1,500 springs behave more like one large surface than 1,500 independent support points.
Pocketed Coils (Marshall Coils)
Each coil is individually wrapped in its own fabric pocket. This allows every coil to compress independently, responding to the specific pressure applied to it without affecting neighbouring coils. The result is targeted support, better pressure relief, and significantly less motion transfer.
Pocketed coils cost more to manufacture. A pocketed coil mattress with 1,000 coils will typically outperform a Bonnell coil mattress with 1,500 coils for motion isolation, pressure relief, and contouring ability.
The Research on Coil Independence
Research published in Applied Ergonomics found that sleep surfaces with independent, zoned support systems produced significantly better spinal alignment across different body types than surfaces with uniform, connected support (Verhaert et al., 2011). Pocketed coils, by design, provide this independent support because each coil responds to its local load without being constrained by adjacent coils.
For couples, the practical benefit is measurable. A study in Sleep and Biological Rhythms showed that motion transfer from a sleeping partner was a leading cause of nocturnal awakenings, second only to noise (Pankhurst and Horne, 1994). Pocketed coils reduce this transfer substantially compared to connected coil systems.
Continuous Coils (Mira-Coil)
A single wire forms rows of S-shaped coils connected in a continuous pattern. This creates a very stable, durable support surface that distributes weight evenly. Continuous coils are firmer than Bonnell coils and more durable, but still transfer more motion than pocketed coils.
You will not see coil counts advertised as prominently with continuous coil mattresses because the counting method differs. The support characteristics come from the wire pattern and gauge rather than the number of individual springs.
Offset Coils
Similar to Bonnell coils but with a flat top and bottom edge that allows them to hinge under pressure. This gives slightly better contouring than Bonnell while maintaining the connected structure. Less common in modern mattresses as pocketed coils have largely replaced this design in the mid-range market.

Wire Gauge: The Number Nobody Talks About
While retailers emphasize coil count, wire gauge quietly determines how the mattress actually feels and how long it lasts.
Gauge measures wire thickness on an inverted scale. Lower numbers mean thicker, firmer wire. Higher numbers mean thinner, softer wire.
| Gauge | Feel | Best For |
|---|---|---|
| 12-13 | Very firm | Heavy sleepers (250+ lbs), people who prefer firm support |
| 13-14 | Medium-firm | Most adults, combination sleepers |
| 14-15 | Medium to soft | Side sleepers, lighter-weight individuals |
| 15-16 | Soft | Comfort layers, pillow tops |
Many premium mattresses use zoned coil systems with different gauges in different areas. Firmer coils (lower gauge) under the hips and lumbar region provide support where your body is heaviest. Softer coils (higher gauge) under the shoulders and legs allow those areas to sink appropriately for spinal alignment.
The Restonic Silk and Wool at Mattress Miracle uses 884 zoned coils. That is fewer than the ComfortCare's 1,222 coils, but the zoned design means each coil is placed with a specific purpose. The Silk and Wool sells for $1,959 compared to the ComfortCare's $999, and the zoned engineering is one reason why.
Dorothy, Sleep Specialist: "When customers ask me about coil count, I always redirect to gauge and zoning. I can show you two mattresses on our floor where the one with fewer coils provides noticeably better support for side sleepers. The coils in the shoulder zone are thinner gauge so they compress more easily, while the hip zone uses thicker gauge for deeper support. You cannot get that effect just by adding more coils of the same gauge."
Where Diminishing Returns Start
Here is the practical question: at what point do additional coils stop making a noticeable difference?
The honest answer is that it depends on coil type and mattress size, but for pocketed coils in a queen mattress, the diminishing returns threshold sits around 1,000-1,200 coils.
Below 800 pocketed coils in a queen, you may notice gaps in support, especially around the edges and in the transition zones between sleep positions. Between 800 and 1,200, each additional coil contributes meaningfully to support consistency and pressure distribution. Above 1,200, the coils are packed closely enough that individual independence begins to decrease. Above 1,400-1,500, the coils are so tightly packed that the support surface begins to behave more like a solid platform than a system of independent springs.
The Physics of Coil Density
A standard queen mattress measures 60 x 80 inches, giving 4,800 square inches of surface area. At 800 pocketed coils, each coil has roughly 6 square inches of territory. At 1,200 coils, that drops to 4 square inches. At 1,500 coils, each coil occupies just 3.2 square inches.
As territory shrinks, the coils physically interfere with each other. The fabric pockets press against neighbouring pockets, reducing the range of independent movement that makes pocketed coils effective. Research on mattress surface response characteristics has confirmed that beyond a certain coil density, the compliance of the support surface plateaus (Defloor, 2000).
This does not mean that 1,400-coil mattresses are bad. The Restonic ComfortCare King has 1,440 pocketed coils and provides excellent support. But the benefit comes from covering a larger surface (king is 76 x 80 inches) rather than from packing more coils per square inch. On a per-area basis, the ComfortCare King's coil density is similar to the Queen's.
Our Range: 690 to 1,440 Coils, Explained
Rather than talking in abstract terms, here are the actual coil counts across the mattresses on our showroom floor at 441 1/2 West Street in Brantford, with context about why each count works for its purpose.
| Model | Size | Coils | Type | Price | Why This Count |
|---|---|---|---|---|---|
| ComfortCare | Twin | 690 | Pocketed | $549 | Appropriate density for twin surface area (38 x 75 in). Adequate for children and lighter adults. |
| ComfortCare | Double | 980 | Pocketed | $749 | Scales proportionally with surface area. Good for teens, single adults. |
| ComfortCare | Queen | 1,222 | Pocketed | $999 | Sweet spot for queen size. High enough for consistent support, not so dense that coils lose independence. |
| Silk and Wool | Queen | 884 | Zoned Pocketed | $1,959 | Lower count but zoned placement. Each coil serves a specific biomechanical purpose. |
| Revive Marissa | Queen | 1,100 | Pocketed | $1,239 | Mid-range count with premium comfort layers. The comfort system does more of the work. |
| Revive Reflections | Queen | 1,200 | Pocketed | $1,785 | Flippable dual-sided design. Coils must support two different comfort surfaces. |
| Tiffany Rose | Queen | 1,188 | Pocketed | $2,199 | Talalay copper latex comfort layers. The premium is in the materials above the coils, not the count. |
| St Charles | Queen | 1,188 | Pocketed | $2,489 | 15-inch flagship. Same coil count as Tiffany Rose, higher price from superior comfort materials. |
| ComfortCare | King | 1,440 | Pocketed | $2,051 | Largest surface area needs more coils to maintain density. Highest count in our lineup. |
Notice something interesting in this table. The two most expensive mattresses (Tiffany Rose at $2,199 and St Charles at $2,489) have the same coil count as the Revive Reflections at $1,785 and fewer coils than the ComfortCare Queen at $999. The price difference comes from the materials above the coils: Talalay copper latex, natural silk and wool, higher-density foams, and more sophisticated comfort layer engineering.
Talia, Showroom Specialist: "I walk customers through this comparison almost daily. People come in looking for the highest coil count they can afford, and I show them the spec cards side by side. The ComfortCare Queen has 1,222 coils for $999. The Tiffany Rose has 1,188 coils for $2,199. The extra $1,200 is not buying more coils. It is buying Talalay copper latex, a thicker comfort system, and materials that breathe differently. Once people see that, the coil count conversation shifts to the right questions."
What Matters More Than Coil Count
If coil count is only part of the story, what else should you evaluate?
Comfort Layer Quality
The foam, latex, or fibre layers above the coils determine the initial feel of the mattress. You are lying on the comfort layers, not directly on the coils. A mattress with 2 inches of 1.2 lb/ft3 foam over 1,200 coils will feel very different from one with 4 inches of 2.5 lb/ft3 foam over 900 coils. The second mattress will likely feel more luxurious and last longer, despite having fewer coils.
Foam density is a strong predictor of durability. Low-density foams (under 1.5 lb/ft3) break down faster, creating body impressions that undermine the support system below. Higher-density foams maintain their shape for years longer. The Restonic Tiffany Rose uses Talalay latex in its comfort layer, which is naturally denser and more resilient than synthetic foam.
Edge Support
The perimeter of a mattress takes disproportionate stress. Sitting on the edge, getting in and out of bed, and sleeping near the edge all load the outer coils heavily. Some mattresses use reinforced edge coils (thicker gauge or encased foam rails) to prevent the "rolling off" feeling. This has nothing to do with total coil count and everything to do with construction design.
Mattress Height
Total height tells you about the volume of material above and below the coil system. An 8-inch mattress has thin comfort layers. A 15-inch mattress (like the Restonic St Charles) has room for multiple comfort layers, transition foams, and a taller coil unit. More material generally means more options for the manufacturer to tune the feel and durability.
Cover and Surface Material
The fabric covering the mattress affects breathability, moisture wicking, and the initial tactile impression. Natural fibres like silk and wool (used in the Restonic Silk and Wool) regulate temperature differently than synthetic fabrics. For Canadian winters and warm summer nights, this matters more than most spec sheets suggest.
Why This Matters in Ontario
Ontario's temperature swings are significant. Brantford can see -20C in January and +35C in July. Mattress materials respond to temperature. Memory foam stiffens in cold rooms and softens in warm ones. Latex maintains more consistent feel across temperature ranges. Coil systems are largely temperature-neutral, which is one reason coil-based mattresses remain popular in climates with wide seasonal variation. The comfort layers on top are where temperature sensitivity lives, and that is another reason to look beyond coil count when evaluating a mattress for year-round use in Southern Ontario.
Coil Count Recommendations by Body Weight
Body weight affects how much you compress the coil system, which influences how many coils you need for adequate support distribution.
| Body Weight | Minimum Queen Coils | Recommended Range | MM Suggestion |
|---|---|---|---|
| Under 130 lbs | 700 | 800-1,000 | ComfortCare (1,222) with softer comfort layers |
| 130-200 lbs | 800 | 1,000-1,200 | ComfortCare or Revive Marissa (1,100) |
| 200-250 lbs | 900 | 1,000-1,400 | Revive Reflections (1,200) or Tiffany Rose (1,188) |
| 250+ lbs | 1,000 | 1,100-1,400+ | ComfortCare King (1,440) or High Density Firm ($690) |
These are starting points, not rules. Research in Applied Ergonomics has shown that individual body geometry and weight distribution patterns create preferences that cannot be reliably predicted from weight alone (Jacobson et al., 2008). Two people at 180 lbs can have very different weight distribution patterns depending on height, build, and body composition. Testing in person remains the most reliable method.
A Practical Test You Can Do in Store
When you lie on a mattress in your normal sleep position, have someone look at your spine from behind (for side sleepers) or from the side (for back sleepers). Your spine should maintain its natural curve without visible sagging at the hips or bridging at the waist. If your hips sink too far, you need more support (firmer coils, higher gauge, or more coils). If your waist does not contact the surface, you need more contouring (softer comfort layers or a zoned coil system).
This visual check tells you more in 30 seconds than any spec sheet can tell you in 30 minutes. Dorothy does this assessment for customers on our showroom floor regularly.
The Marketing Coil Count vs the Real One
One last thing worth knowing. Some manufacturers count coils differently.
A "double-stacked" or "micro-coil" comfort layer might add 500-800 tiny coils on top of the primary support coils. The manufacturer then advertises the combined total: "2,000 coils." The primary support system might have 1,000 coils, with another 1,000 micro-coils in the comfort layer serving a completely different function.
This is not dishonest, but it is misleading if you are comparing that "2,000 coil" mattress against a conventional "1,200 coil" mattress. You are comparing different things. The primary support coil count is what matters for structural comparison. Comfort layer micro-coils are a nice feature, but they serve a cushioning role more similar to foam than to structural springs.
Ask specifically: "How many coils are in the primary support system?" That is the number you can compare across brands.

How many coils should a good queen mattress have?
A quality queen mattress should have at least 800 pocketed coils for adequate support. Most mid-range to premium models fall between 1,000 and 1,400 coils for a queen size. Above 1,400, the differences become harder to feel because the coils are packed so tightly that individual movement is restricted. The Restonic ComfortCare queen at Mattress Miracle has 1,222 pocketed coils, which sits in the sweet spot for support and responsiveness.
Is a higher coil count always better?
No. Coil count has diminishing returns past approximately 1,000-1,200 coils in a queen size. Beyond that threshold, the coils are packed so closely that they begin to behave more like a solid surface than independent springs. Coil type (pocketed vs Bonnell), wire gauge, and comfort layer quality matter as much as or more than count. A 900-pocketed-coil mattress will typically outperform a 1,500-Bonnell-coil mattress for motion isolation and pressure relief.
What is the difference between pocketed coils and Bonnell coils?
Pocketed coils are individually wrapped in fabric sleeves and compress independently, meaning movement on one side does not transfer to the other. Bonnell coils are connected hourglass-shaped springs that move as a unit, transferring motion across the surface. Pocketed coils offer better pressure relief and motion isolation for couples but cost more to manufacture.
Does coil gauge affect mattress firmness?
Yes. Coil gauge measures wire thickness, and lower gauge numbers mean thicker, firmer wire. A 13-gauge coil is firmer than a 15-gauge coil. Most quality mattresses use coils between 13 and 15 gauge. Some premium mattresses use zoned coils with different gauges in different areas, providing firmer support under the hips and softer compression under the shoulders. See our firmness scale guide for more detail.
How many coils does a Restonic ComfortCare have?
The Restonic ComfortCare line at Mattress Miracle ranges from 690 pocketed coils in a twin ($549) to 1,440 pocketed coils in a king ($2,051). The queen size has 1,222 pocketed coils and is priced at $999. All ComfortCare models use the same pocketed coil design with multiple comfort layers including gel memory foam.
