What Are Mattress Coils? Types of Coils and Ideal Coil Count for a Better Sleep

It is common for one to find several technical terms while shopping for a mattress including foam density, hybrid design, motion isolation, lumbar support, and perhaps most importantly, mattress coils.
The core support system used in high-end mattresses are coils (springs). They directly determine how durable and comfortable the mattress is, along with pressure relief, spinal alignment, motion transfer and overall comfort.

Understanding coil technology is critical to choosing the right mattress for your long-term comfort, whether you're upgrading your sleep setup, relocating, or choosing a Queen size mattress or King size mattress.

In today’s blog, we’ll explore:

• What coils are
• Types of coils used in modern mattresses
• Ideal number of coils based on mattress type and size
• Which coil system is best for different sleeping needs
• Where to buy premium coil mattresses in Saskatoon at the best price in town

Let’s dive in.

What Are Mattress Coils?

Springs in a mattress consist of a metal support system that holds body weight, helps keep the spine aligned, and improves longevity. These coils are usually made from tempered high-carbon steel, which is crafted to bend and hold shape with every flex:

• Support for your spine

• Pressure relief for your hips, shoulders, and back

• Responsiveness and bounce

• Durability and shape retention

• Airflow for a cooler sleep

Even though foam materials can sometimes trap heat or feel extra soft, coil mattresses are supportive and breathable which is an excellent option for people who need long-term comfort and good posture alignment.

 Types of Mattress Coils 

Not all coils are the same. Each coil type creates a different sleeping experience. Below are the most common and most demanded coil systems:

Pocket Coils

Pocket coils (also called individually wrapped coils) are today’s most popular technology. Each spring is wrapped in its own fabric pocket, allowing independent movement.

Benefits:

• Excellent motion isolation — ideal for couples
•  Contours to the body for tailored support
• Reduces pressure on joints
•  Durable and long-lasting structure

Pocket-coil mattresses are commonly preferred by shoppers looking for a luxury feel in both queen size mattress and king size mattress.

---

 IntelliCoils

IntelliCoils are commonly found in ultra-premium designer mattresses. This technology uses two coils in one — an outer coil for softness and an inner coil for deep support.

Benefits:

• Plush surface feel with strong underlying support
• Best for people with back or neck pain
• Prevents sagging over time
• Great for all sleep positions (side, back, stomach)

If you’re someone who wants the perfect balance of comfort and orthopedic support, an IntelliCoil mattress is worth considering.

 Continuous Coils

A continuous coil system uses a single long wire to form a network of interconnected springs.

Benefits:

• Very durable and budget-friendly
• Good support for children and teens
• Lightweight and easy to move

They are firm and supportive but not the best option for couples due to motion transfer.

---

 Bonnell Coils

Bonnell coils are hourglass-shaped springs linked together. They are one of the oldest coil designs and commonly used in value-range mattresses.

Benefits:

•  Affordable
• Good support for guests/occasional use
• Strong and reliable

While economical, they don’t match the comfort or motion control of pocket coils or IntelliCoils.

---

 Micro Coils

Micro coils are tiny springs layered on top of full-sized coils or foam.

Benefits:

• High-end body contouring
• Improved airflow and breathability
• Luxurious plush feel

Premium hybrid mattresses often combine micro coils and pocket coils for top-tier comfort.

 How Many Coils Should a Mattress Have?

More coils generally mean better support and longer durability — but it must be balanced with coil quality and gauge thickness. Below is an ideal coil count reference based on mattress size:

 

💡 Note: Coil count alone does not define quality — coil type, thickness, and design also matter. For example, 850 IntelliCoils can outperform 1500 basic Bonnell coils.

---

 Coil Gauge: Another Factor That Matters

Coil gauge = thickness of the wire
Lower gauge = thicker coil = firmer support

For most sleepers — especially couples and people with back pain — a medium-firm pocket-coil mattress offers the healthiest combination of comfort and support.

 Which Mattress Is Right for You?

If you're unsure, test-sleeping a mattress in-store is always the best way to feel the difference.
