Quick Answer: When comparing premier king mattresses, focus on coil count (1,000+ for kings), edge support reinforcement, and comfort layer density rather than brand marketing. In-store coil-based kings ($1,400-$2,500 CAD) typically outlast and out-support online all-foam kings at the same price. The Restonic ComfortCare King at $2,051 with 1,440 coils is the value benchmark in this category.

The Premier King Landscape in 2026
The Canadian king mattress market has changed significantly in the last five years. Online brands have driven prices down at the entry and mid levels, while traditional manufacturers have responded by packing more features into their premium tiers. For shoppers, this means more options than ever, and more confusion about what actually constitutes a premier king mattress versus one with premier marketing.
We see both sides of this from our Brantford showroom. Customers walk in having compared Nectar, Casper, Endy, and Douglas online, then lie on a Restonic or Sleep In and discover that coil-based support feels fundamentally different from foam. Neither is objectively better. They are different constructions that suit different sleepers.
What matters is understanding the trade-offs so you spend your money on features that actually improve your sleep, not on branding or clever packaging.
Head-to-Head: 5 Premier Kings Compared
Here are five king mattresses spanning the "premier" price range, with real specs and current Canadian pricing.
| Model | Type | King Price (CAD) | Coils | Height | Edge Support | Trial |
|---|---|---|---|---|---|---|
| Restonic ComfortCare | Innerspring | $2,051 | 1,440 | 12" | Reinforced | In-store test + guarantee |
| Nectar Premier | All-foam | $1,599-$1,799 | 0 | 13" | Weak | 365 nights |
| Nectar Premier Copper | All-foam | $2,199-$2,499 | 0 | 14" | Weak | 365 nights |
| Restonic Luxury Silk/Wool | Innerspring | ~$1,800 | 884 (zoned) | 14" | Reinforced | In-store test + guarantee |
| Sleep In Flippable | Dual-sided coil | ~$1,600-$2,200 | Varies | 13" | Good | In-store test |
A few things jump out from this comparison. The Restonic ComfortCare at $2,051 delivers the highest coil count of any model here, including options that cost $500-$1,000 more. Coil count is not everything, but 1,440 individually wrapped coils in a king provides excellent point-by-point support and motion isolation.
The Nectar models compete on trial period and convenience. If you live far from a mattress store or genuinely prefer the online buying experience, the 365-night trial mitigates the risk. But you are paying more for less structural support, and you cannot test the feel beforehand.
Online vs In-Store Kings: What Actually Differs
This is not about brand loyalty. It is about construction constraints. Online mattresses must ship compressed in a box, which limits what manufacturers can put inside.
Construction Limitations of Boxed Mattresses
Coil mattresses can be compressed and rolled, but the process stresses the coils and requires thinner gauge wire to survive compression without permanent deformation. Many online brands avoid this entirely by using all-foam construction, which compresses easily but lacks the airflow and structural support of coils.
Hybrids (foam + coils) bridge the gap, but boxed hybrids often use shorter, thinner coils than their in-store equivalents. A 2022 industry analysis by Furniture Today noted that the average coil count in boxed hybrid kings was 800-1,000, compared to 1,000-1,500 in traditionally delivered kings.
Edge Support: The King-Specific Issue
Edge support matters more in a king than any other size because both sleepers tend to gravitate toward their respective sides. If the edges compress under body weight, you effectively lose several inches of sleeping surface on each side, negating some of the width advantage of upgrading to king.
Coil-based kings with reinforced perimeters maintain their edge integrity for years. All-foam kings compress progressively, and the edges soften fastest because that is where the foam gets the most concentrated stress. Research from the International Journal of Industrial Ergonomics has shown that foam mattress edges lose 15-25% of their support within the first two years of use.
Dorothy, Sleep Specialist: "When couples test a king in our showroom, I always ask both people to lie near their respective edges. On a coil mattress, they stay supported. That is the difference you feel immediately but would take months to notice at home on a foam mattress."
Temperature: Coils Breathe, Foam Traps
King mattresses trap more body heat than smaller sizes because two bodies generate more thermal energy in a larger enclosed space. All-foam construction compounds this because foam is an insulator by nature.
Coil systems create natural air channels through the mattress. Every time you shift position, the coils compress and release, pumping air through the mattress interior like a very slow bellows. This passive ventilation keeps a coil king 2-4°C cooler at the sleeping surface compared to an equivalently priced all-foam king, according to testing published in Sleep Science and Practice (2021).
For hot sleepers sharing a king, this temperature difference can be the difference between sleeping through the night and waking up overheated at 3 a.m.
Where the Value Actually Lives
Here is how we think about value when recommending premier king mattresses to customers.
Under $1,500 CAD: The Restonic ComfortCare King at $2,051 is hard to beat. You get 1,440 individually wrapped coils, reinforced edges, a 12-inch profile, and the ability to test it in person. At this price, no online all-foam king matches it on support specs.
$1,500-$2,000 CAD: This is where you choose between construction philosophies. The Restonic Luxury Silk and Wool offers natural fibre comfort layers and zoned coils. The Sleep In Flippable offers dual-sided longevity. Both outperform similarly priced online foam models on durability and support, though the foam models win on motion isolation.
Over $2,000 CAD: At this tier, you should be getting premium comfort materials (Talalay latex, natural wool, silk), high coil counts, and excellent build quality. Be skeptical of all-foam mattresses at this price. The materials in an all-foam mattress do not justify luxury pricing when coil-based alternatives offer more for less.
The Durability Question
Consumer Reports' mattress durability testing found that innerspring mattresses retained their support characteristics an average of 2.3 years longer than all-foam equivalents. For a king mattress that costs $1,500+, those extra years represent significant value. A mattress that lasts 10 years versus 7 effectively costs 30% less per year of use.
Flippable mattresses extend this further. By alternating sleeping surfaces every 6-12 months, you distribute wear across twice the material. Many of our Sleep In customers report 12+ years of comfortable use from a single flippable mattress.

What to Test When Shopping for a Premier King
If you have the option to test king mattresses in a store, here is what to evaluate. These are the things that matter most for long-term satisfaction, based on research from the Canadian Chiropractic Association and our own 37+ years of customer feedback.
1. Lie in your actual sleeping position for at least 5 minutes. The initial impression of a mattress changes after your body settles. Side sleepers: check that your shoulder sinks enough to keep your spine straight. Back sleepers: ensure your lower back feels supported, not bridged. Stomach sleepers: your hips should not sink deeper than your chest.
2. Roll over. A good king should let you change positions easily. Memory foam creates a "hammock" effect that requires more effort to roll out of. Coil mattresses are more responsive and make position changes easier.
3. Sit on the edge. If the edge compresses more than an inch or two under your seated weight, it will compress more over time. Strong edges mean more usable sleeping surface.
4. Test with your partner. Have one person lie still while the other changes position. You should not feel your partner's movement significantly. Individually wrapped coils and all-foam construction both excel here, but for different reasons.
5. Ask about the return or exchange policy. Even in-store testing cannot perfectly predict 6-month satisfaction. A comfort guarantee or exchange policy gives you a safety net.

Are online king mattresses as good as in-store ones?
Online king mattresses can be good quality, but they tend to be all-foam or foam-heavy hybrids because coil mattresses are harder to compress and ship in a box. This means online kings generally have less edge support, more heat retention, and a shorter lifespan compared to traditional coil-based kings at similar price points. The trade-off is convenience and generous trial periods.
What coil count should I look for in a premier king mattress?
For a king-size mattress, look for at least 1,000 individually wrapped coils. Higher-end models may have 1,200 to 1,500 or more. More coils generally mean better contouring and less motion transfer, though coil gauge (thickness) and coil height also affect performance. Our Restonic ComfortCare King has 1,440 coils, which is among the highest in its price category.
Is it worth spending over $2,000 on a king mattress?
Above $2,000 for a king, you enter the territory of luxury materials like Talalay latex, natural silk and wool, and high-end zoned coil systems. These additions improve temperature regulation, durability, and pressure relief. Whether they are worth it depends on your sleep needs and budget. For most people, a well-built king in the $1,400-$2,000 range provides excellent sleep quality.
How long does a premier king mattress last?
A quality coil-based king typically lasts 8 to 10 years. All-foam kings tend to last 6 to 8 years, as foam breaks down faster than coils under the distributed weight of two sleepers. Flippable mattresses can last 10 to 15 years because you can alternate sleeping surfaces. Regular rotation every 3 to 6 months extends any mattress's life.
