Pocket Coil vs Innerspring Mattress (2026): What the Difference Means for Support, Motion and Durability
Pocket coils, Bonnell, offset and continuous coil innersprings behave differently under your body. What each one does, what gauge, count and coil height mean on a spec sheet, and the five questions that expose a vague listing.
AI Overview answer
What is the difference between a pocket coil and an innerspring mattress?
Quick answer: A pocket coil mattress uses individual springs, each sealed in its own fabric sleeve, so each coil compresses on its own. A traditional innerspring uses coils wired together into one unit, so pressure in one place pulls on the coils around it. The Sleep Foundation describes pocketed coils as moving only when pressure is placed directly on them, which is why they contour more closely and pass less motion to a partner. Wired innersprings are simpler and usually cheaper, with a bouncier, more uniform feel.
Most mattresses sold online in Canada as "hybrids" put pocket coils under foam or latex. Both mattresses Hamuq sells do: the Original Hybrid sits on a 9-inch core of individually wrapped pocket coils, according to Hamuq's FAQ page.
Before you buy
Pocket coil or innerspring: which one fits you?
Lean pocket coil if
You share the bed with a light sleeper, you sleep on your side and want the shoulder and hip to sink in, or you want support that responds to each part of the body separately.
Lean wired innerspring if
You want the lowest price, a springy and even feel, and you sleep alone or with someone who does not wake when you move.
Look past the coil type if
The real choice is coils versus all-foam, or the listing gives no gauge, height or comfort layer details. Those matter as much as the label.
How do Bonnell, offset, continuous and pocket coils differ?
Bonnell innerspring. Hourglass-shaped coils, wider at the top and bottom, linked to their neighbours by thin spiral helical wires. The Sleep Foundation calls it one of the least expensive coil types. Because every coil is tied to the next, the unit moves together: the feel is springy and even, motion carries across the bed, and one area cannot easily be made firmer than another.
Offset coil. Also hourglass-shaped, but with squared sides that, in the Sleep Foundation's description, flex like a hinge under light pressure and push back harder under more load. Offset coils are still wired together, but respond to movement without passing as much motion along as Bonnell coils. They cost more to make.
Continuous coil. One long wire formed into rows of coils. The Sleep Foundation describes it as highly durable and inexpensive, with less contouring than offset coils, and notes it may pass on some movement.
Pocket coil, also called wrapped or individually encased coil. Each spring sits in its own fabric pocket, and the pockets are joined to each other rather than the springs being wired together. Leggett & Platt, a large coil maker, says its individually wrapped coils each flex and move independently and isolate motion to reduce partner disturbance. That independence is what lets a pocket coil bed contour to the shoulder and hip, and lets a maker vary support across the bed. The trade-off the Sleep Foundation notes is price: pocketed coils are more complex to build.
| Feature | Bonnell | Offset | Continuous | Pocket coil |
|---|---|---|---|---|
| How coils connect | Helical wires tie each coil to its neighbours | Wired, with squared hinge-like sides | One wire formed into rows | Fabric pockets; springs not wired together |
| Contouring | Low | Moderate | Low | High |
| Motion transfer | High | Lower than Bonnell | Some | Low; foam above also matters |
| Varying support across the bed | Hard; the unit acts as one | Limited | Limited | Possible, by gauge or coil height |
| Relative cost | Among the lowest | Higher than Bonnell | Low | Higher |
| Where you see it | Entry-level and some retail beds | Some traditional innersprings | Entry-level retail beds | Most online hybrids |
What do gauge, coil count and coil height mean on a spec sheet?
Gauge. The thickness of the wire. Lower numbers mean thicker wire and a firmer coil; the Sleep Foundation gives a typical range of 13 to 17 gauge. A mattress that lists two gauges is usually using the thicker one where it wants more support, such as the middle or the perimeter.
Coil count. The number of springs in a given size, usually quoted for a queen; the Sleep Foundation puts typical queen counts at roughly 400 to 1,200. Counts rise with smaller coils and fall with larger ones, so a higher count does not mean a better bed on its own. A count without the size and gauge next to it tells you very little, which is why this guide does not rank beds by it.
Coil height. The height of the spring unit before the comfort layers. The Sleep Foundation calls about 6 inches standard, with microcoils of 1 to 3 inches used in comfort layers. Taller units generally give more travel before the coil bottoms out.
Tempering. Heat treatment after the coil is formed, which helps the steel keep its shape. "Double tempered" means the process is done twice.
Edge build. Some hybrids surround the coil unit with a foam rail for edge support; others use firmer perimeter coils. Ask which, because the listing rarely says.
| Spec | Typical range | What it tells you | What it does not |
|---|---|---|---|
| Gauge | 13 to 17 | Lower is thicker and firmer wire | How the whole bed feels once foam is added |
| Coil count (queen) | About 400 to 1,200 | How many springs share the load | Quality or support on its own |
| Coil height | About 6 in standard; microcoils 1 to 3 in | How much travel the springs have | Firmness of the top layers |
Which coil system suits which sleeper?
- Couples who wake each other: pocket coils, with enough foam or latex above them to absorb the rest. Our motion transfer guide covers the foam side.
- Side sleepers with shoulder or hip pressure: pocket coils, because independent springs let the shoulder sink while the waist stays supported. If you have ongoing pain, talk to a doctor or physiotherapist; a mattress is not a treatment. Firmness by position is in our firmness chart.
- Heavier sleepers: pocket coils in a thicker gauge, or a taller unit, rather than a wired innerspring that will hammock. See our guide for heavier sleepers.
- Sleepers who want bounce and a uniform feel at the lowest price: a Bonnell or continuous coil bed is the honest budget choice, as long as you are not sharing it with a light sleeper.
- Anyone who sits on the edge to dress: ask how the perimeter is built. Our edge support guide explains why it matters.
Are pocket coils quieter than innerspring coils?
The Sleep Foundation notes that friction between Bonnell coils may produce some noise. Pocket coils are commonly described as quieter because fabric separates the springs, but we found no manufacturer test that measures coil noise. In practice, most bed noise comes from the frame, slats or box spring rather than the coils. If your bed is already squeaking, our guide on why a hybrid mattress squeaks walks through how to find the source.
Is a coil mattress better than all-foam?
A pocket coil bed is not automatically better than an all-foam bed. Foam absorbs movement well and has no springs. Coils let more air move through the core and give more push-back. If that is the decision you are really making, our memory foam vs hybrid guide is the next read, and the latex hybrid vs foam hybrid guide covers what goes on top of the coils.
What coils do Hamuq mattresses use?
Hamuq sells two mattresses, and both are pocket coil hybrids. Hamuq's FAQ page, read September 25, 2026, lists the Original Hybrid as a 1-inch quilted pillow top, 2 inches of Cloud Tech Soft foam, a half inch of TRS Adaptive Gel foam and a 9-inch support core of individually wrapped pocket coils, 12 inches tall in total. The Organic Hybrid has an organic cotton cover, a wool quilt layer, a natural latex layer and a microcoil layer over a pocket coil base.
Hamuq product context
Two pocket coil hybrids
The Original Hybrid is medium-firm and costs $999 CAD in queen. The Organic Hybrid is firmer than the Original Hybrid and costs $1,999 CAD in queen. Both ship free across Canada (additional charges may apply to the Territories), come with a 120-night trial with a 30-night minimum, and a 15-year limited warranty that expects a firm, supportive base.
Hamuq Inc. sells the mattresses named here. Prices were read from Hamuq product data on September 25, 2026 and can change; the product page shows the live price.
What five questions expose a vague coil listing?
- Are the coils individually wrapped, or wired together?
- What gauge, and is more than one gauge used?
- How tall is the coil unit?
- Is the edge a foam rail or firmer coils?
- What sits directly on the coils, and how thick is it?
A seller who can answer these from the product page or FAQ is describing a real build. One who answers "premium coils" is describing a price. The base underneath matters as much as the coils; our guide to what bed frame a hybrid needs covers slat spacing and warranty rules.

Buyer questions
Coil mattress FAQs for Canadian buyers
What is a pocket coil mattress?
Quick answer: A mattress whose support core is made of individual steel springs, each sealed in its own fabric pocket so it compresses independently of its neighbours. Pocket coils contour to the body and reduce motion transfer. Most online hybrids in Canada use them.
Is a pocket coil mattress better than an innerspring?
Quick answer: For contouring and motion isolation, generally yes. A wired innerspring is cheaper, bouncier and more uniform, which some sleepers prefer. Gauge, coil height and the layers on top matter as much as the coil type.
What does coil gauge mean?
Quick answer: The thickness of the wire. Lower gauge numbers are thicker and firmer; the Sleep Foundation gives a typical range of 13 to 17 gauge.
Does a higher coil count mean a better mattress?
Quick answer: Not on its own. Count depends on coil size and mattress size, so a queen with smaller coils will have more of them without being more supportive. Gauge, coil height and what sits above the coils matter more.
Are pocket coil mattresses quieter?
Quick answer: They are commonly described that way because fabric separates the springs, but we found no test that measures coil noise. Most bed noise comes from the frame or base; see our squeaking guide to find the source.
Do pocket coil mattresses sag?
Quick answer: Any mattress can develop body impressions, especially on an unsupportive base. Hamuq's warranty, for example, covers visible indentation greater than one inch when the mattress is on a firm, supportive base.
Are Hamuq mattresses pocket coil?
Quick answer: Yes. Hamuq's FAQ page lists a 9-inch core of individually wrapped pocket coils in the Original Hybrid, and a pocket coil base under a microcoil layer in the Organic Hybrid, as of September 2026.
How we know this
This guide was updated on September 25, 2026. The descriptions of Bonnell, offset, continuous and pocketed coils and the typical gauge, count and height ranges come from the Sleep Foundation's coil types guide (last updated July 25, 2025); the description of how individually wrapped coils move comes from Leggett & Platt. The sleeper recommendations are our summary of those descriptions, not the result of a test we ran. Hamuq construction was read from Hamuq's FAQ page, prices from Hamuq product data, and trial, warranty and shipping terms from Hamuq's policy pages, all on September 25, 2026. No coil counts are ranked or quoted for any brand.
