Decoding Comfort: What is a Coil Spring Mattress?

We spend a third of our lives asleep - or at least, we're supposed to. Given that, the type of mattress you sleep on isn't just a piece of bedroom furniture; it's an investment in your well-being.

You've probably heard terms like memory foam, latex, hybrid, and yes - coil spring mattresses. But what exactly is a coil spring mattress, and is it the right choice for you? Prepare to be enlightened.

Coil Spring Mattress

A coil spring mattress, also known as an innerspring mattress, is one of the most traditional and commonly used types of mattresses. It consists of a series of spring coils that provide the support structure, sandwiched between layers of padding and fabric. Here’s what you need to know.

Structure of a Coil Spring Mattress

  • Spring Core: This is the heart of the mattress, made of metal coils.
  • Comfort Layer: Situated above the spring core, this layer adds cushioning and is made from materials like foam, cotton, or even more springs.
  • Foundation Layer: Typically made from a sturdy material like wood, this layer supports the coil springs.

Types of Coil Springs

Did you think all coil springs are created equal? Think again.

  • Bonnell Coils: The oldest and most common type, shaped like an hourglass.
  • Pocketed Coils: Each coil is individually wrapped, reducing motion transfer.
  • Offset Coils: Designed to conform to the body's shape, these are similar to Bonnell but with a hinged effect.
  • Continuous Coils: Made from a single piece of wire shaped into rows, these provide a stable, interconnected structure.

How Do Coil Spring Mattresses Compare?

Now, let's dive into the nuanced world of mattress comparisons.

Coil Spring vs. Memory Foam

  • Support: Coil springs offer more active support, while memory foam offers pressure relief.
  • Temperature: Coil springs are generally cooler, thanks to air circulation between the coils.

Coil Spring vs. Latex

  • Bounce: Coil springs offer more bounce and are easier to move on.
  • Durability: Latex tends to last longer than coil springs.

Coil Spring vs. Hybrid

  • Cost: Coil spring mattresses are usually more affordable.
  • Comfort: Hybrids offer a blend of support and cushioning, often combining coil springs and memory foam.

Advantages and Disadvantages of Coil Spring Mattresses

Every coin has two sides, and so does every coil spring mattress.


  • Affordable: Generally less expensive than other types.
  • Cooler Sleep: Allows for better air circulation.


  • Limited Contouring: Less effective in conforming to your body shape.
  • Motion Transfer: You might feel your partner moving in bed.

Who Should Consider a Coil Spring Mattress?

So, is a coil spring mattress the sleeping cloud of your dreams?

  • For Hot Sleepers: If you often find yourself hot and bothered at night, the air circulation in a coil spring mattress might be a godsend.
  • For Budget Buyers: If you're looking for a bang-for-your-buck option, coil springs usually offer that.

How to Maintain a Coil Spring Mattress

Got your coil spring mattress? Great. Now, keep it in tip-top shape.

  • Regular Rotations: Rotate your mattress every three months to distribute wear evenly.
  • Use a Mattress Protector: Protect your investment from spills and stains with a quality mattress protector.
  • Avoid Jumping on the Bed: This isn't just a rule for kids; it helps maintain the structure of the coils.


Coil spring mattresses have been the go-to choice for sleepers for many years, and for good reason. They offer a range of benefits from cost-effectiveness to a cooler sleep.

However, they're not for everyone. If you value contouring support or motion isolation more, then you might want to consider other options. But if you're a hot sleeper looking for an affordable and supportive mattress, coil springs could be your sleep savior. Sweet dreams!
