Quick Answer: A king premier mattress combines king-size dimensions (76" x 80") with premium construction materials. Look for individually wrapped coils (1,000+), reinforced edge support, and quality comfort layers rather than just a luxury brand name. In Canada, premium kings range from $1,400 to $3,500 depending on construction. The best way to evaluate one is to test it in person.

Why Couples Upgrade to King (and Whether You Should)
The most common reason people walk into our Brantford showroom asking about king mattresses is space. A queen gives each person 30 inches of width. A king gives each person 38 inches. That extra 8 inches per side is roughly the difference between sleeping on a twin and a twin XL, and it changes how couples sleep together.
Research published in Sleep and Biological Rhythms (2012) found that couples sleeping on larger mattresses reported fewer nighttime awakenings and higher subjective sleep quality scores. The effect was most pronounced in couples where one or both partners were restless sleepers.
That said, a king is not for everyone. It costs more, requires a bigger room, and needs a proper frame with centre support. If you are happy on your queen and your room is on the smaller side, upgrading to a premium queen might serve you better than a standard king.
Brad, Owner, 40+ years of experience: "About a third of our customers come in looking at queens and leave with a king. Once they lie on a king in the showroom, particularly couples, they realize how much extra room changes the feel. But I always tell people to measure their bedroom first. A king in a room that is too small just creates traffic problems."

King Sizes Explained: Standard vs California vs Split
| Size | Dimensions | Best For | Availability in Canada |
|---|---|---|---|
| Standard King | 76" x 80" (193 x 203 cm) | Most couples, wider room | Very common, all retailers |
| California King | 72" x 84" (183 x 213 cm) | Tall sleepers (6'2"+), narrower rooms | Limited, mostly online or special order |
| Split King | Two 38" x 80" pieces | Couples with different firmness needs, adjustable bases | Available at specialty stores |
In Canada, the standard king dominates. Roughly 85% of king mattresses sold are standard kings. Sheets, protectors, and bed frames are all more widely available and cheaper in standard king than California king. Unless you are over 6 feet 2 inches and genuinely need the extra 4 inches of length, standard king is the practical choice.
The split king deserves special mention for couples considering adjustable beds. Two twin XL mattresses placed side by side create a split king, allowing each partner to raise their head or feet independently. If you snore and your partner does not, a split king on adjustable bases with separate remotes can be a relationship saver.
What Separates a Premium King from a Basic One
The word "premier" or "premium" gets thrown around loosely in the mattress industry. Here is what actually distinguishes a well-built king from a budget one, based on the construction features we have observed across brands over 37 years in business.
Coil Count and Type
In a king-size mattress, coil count matters more than in smaller sizes because there is more surface area to support. A good king premier mattress should have at least 1,000 individually wrapped coils. Our Restonic ComfortCare King has 1,440 coils, which is among the highest in its price class.
Individually wrapped (pocketed) coils move independently, so when one partner shifts position, the motion stays localized. Older continuous coil and Bonnell coil systems transfer more movement and tend to feel bouncier, which is fine for some sleepers but not ideal for couples.
Zoned Coils: Worth the Upgrade?
Some premium kings feature zoned coil systems with firmer support under the hips and lumbar and softer coils under the shoulders. Research in Applied Ergonomics (Verhaert et al., 2013) found that zoned support systems improved spinal alignment measurements compared to uniform coil tension, particularly for side sleepers. Our Restonic Luxury Silk and Wool model uses 884 zoned coils for this reason.
Edge Support
King mattresses have more edge perimeter than any other size, and poor edge support means wasted sleeping surface. Premium kings use reinforced edge systems, usually denser foam encasements or thicker wire around the perimeter coils, that prevent the sinking feeling when you sit on the side of the bed or sleep near the edge.
This is one of the biggest differentiators between coil-based and all-foam kings. All-foam mattresses (including brands like Nectar and Casper) consistently score lower on edge support because foam compresses under concentrated weight without the structural resistance that coils provide.
Comfort Layers
The materials on top of the coils determine how the mattress feels. Premium comfort layers include:
- Gel memory foam: Contours to body shape, good for side sleepers. Sleeps warmer than other options
- Talalay latex: Responsive, naturally cooling, hypoallergenic. More expensive but more durable than foam
- Natural fibres (silk, wool, cotton): Excellent temperature regulation, breathable. Found in luxury-tier mattresses
- Copper-infused foam: Thermally conductive, newer technology. Found in mid-to-high tier foam mattresses
For a comparison of specific models including all-foam options, see our Nectar Premier mattress review or our premier king comparison guide.
Construction Types for Premium Kings
| Type | Strengths | Weaknesses | Price Range (King, CAD) |
|---|---|---|---|
| Innerspring (pocketed coils) | Airflow, edge support, responsiveness | More motion transfer than foam | $1,200-$3,500 |
| All-foam | Motion isolation, pressure relief, lower cost | Heat retention, poor edge support, less durable | $800-$2,500 |
| Hybrid (coils + foam) | Balanced feel, good airflow, good motion isolation | Heavier, often more expensive | $1,500-$4,000 |
| Flippable (dual-sided) | Two firmness options, doubled lifespan | Heavier, fewer comfort layer options | $1,400-$2,800 |
| Natural latex | Durable, breathable, hypoallergenic | Expensive, less contouring than foam | $2,000-$5,000+ |
King Specs That Actually Matter When Shopping
Mattress marketing focuses on brand names and buzzwords. Here are the specifications that actually predict long-term satisfaction, according to sleep research.
Coil gauge: Lower gauge numbers mean thicker, firmer coils. Most premium mattresses use 13-15 gauge coils. If you weigh over 200 lbs, look for 13-14 gauge for better long-term support.
Foam density: Measured in pounds per cubic foot (PCF). Comfort foam under 3.0 PCF will develop body impressions faster. Premium mattresses use 4.0+ PCF memory foam and 1.8+ PCF polyfoam in support layers.
Total height: A good king premier typically stands 12-15 inches tall. Under 10 inches often means skimping on comfort layers. Over 15 inches can make getting in and out of bed difficult, particularly on top of a box spring.
Certification: CertiPUR-US certification means the foams have been tested for harmful chemicals and VOC emissions. For natural materials, look for GOLS (latex) or GOTS (textiles) certification.

Canadian King Pricing: What to Expect in 2026
King mattresses in Canada cost more than their US equivalents, typically 10-20% more depending on the brand and whether it is manufactured domestically. Here is a realistic pricing guide.
| Tier | Price Range (King, CAD) | What You Get |
|---|---|---|
| Budget | $600-$1,200 | Basic foam or Bonnell coil, shorter lifespan, limited comfort features |
| Mid-range | $1,200-$2,000 | Pocketed coils or quality foam, good comfort layers, decent edge support |
| Premium | $2,000-$3,500 | High coil counts, luxury comfort materials, zoned support, excellent edge |
| Luxury | $3,500+ | Natural latex, organic materials, handcrafted, specialty constructions |
In our experience, the best value in premium kings sits in the $1,400-$2,200 range. Below $1,400, manufacturers start cutting corners on coil count or foam density. Above $2,200, you are often paying for brand name and packaging rather than meaningfully better sleep.
Statistics Canada's Consumer Price Index shows mattress prices increased roughly 8% nationally between 2023 and 2025, driven by material costs and supply chain adjustments. Domestic Canadian manufacturers like Sleep In have absorbed some of these increases, while imported brands have passed more of the cost to consumers.
Room and Setup Requirements for a King
Before buying a king premier mattress, make sure your space can handle it.
Minimum room size: 12 x 12 feet (3.7 x 3.7 m) for the bed plus walking space. Ideally 12 x 14 feet or larger if you want nightstands and a dresser.
Doorway clearance: Standard Canadian interior doorways are 32 inches wide. A king mattress is 76 inches wide but compresses somewhat. It will fit through most doorways when tilted, but tight hallway corners can be challenging. Our white glove delivery team handles this regularly and knows how to navigate older Brantford homes with narrower passageways.
Frame requirements: King beds need centre support to prevent sagging. A platform bed with a solid or closely spaced slat system works well. If using a traditional frame, make sure it includes a centre rail with at least one support leg touching the floor.
Delivery to Brantford and Beyond
Our white glove delivery covers Brantford and extends to Hamilton, Burlington, Mississauga, Toronto, Kitchener, Waterloo, Guelph, Cambridge, St. Catharines, Niagara Falls, London, Barrie, and Oshawa. The team handles positioning, packaging removal, and old mattress takeaway. For king-size deliveries especially, professional setup is worth it. A king mattress weighs 80-150 lbs depending on construction, and manoeuvring it up a staircase without help is an experience best avoided.

What is the difference between a king and a California king mattress?
A standard king measures 76 inches wide by 80 inches long, while a California king is 72 inches wide by 84 inches long. The standard king gives couples more side-to-side room, while the California king suits taller sleepers (over 6 feet 2 inches) who need extra length. In Canada, standard king is far more common and easier to find sheets and accessories for.
How much should a premium king mattress cost in Canada?
Premium king mattresses in Canada typically range from $1,400 to $3,500 depending on construction and materials. A quality king with individually wrapped coils and good comfort layers starts around $1,400-$1,800 at in-store retailers. Online all-foam kings start lower but may lack the support features of coil-based models.
Do I need a special bed frame for a king mattress?
Yes. A king mattress requires a king-size bed frame or platform with centre support. Unlike queen frames, king frames need a centre support bar or legs to prevent sagging in the middle. Most king bed frames and platform bases include this, but it is worth checking before purchase. A box spring or foundation should also be king-size.
Will a king mattress fit in a standard Canadian bedroom?
A king mattress needs a room that is at least 12 feet by 12 feet (3.7 m by 3.7 m) to allow space for walking around the bed and fitting nightstands. Many Canadian master bedrooms built after 1990 accommodate a king, but older homes with smaller rooms may not. Measure your room before purchasing.
