Spring Mattress vs Foam Mattress: What’s The Difference?

Are you looking for a new mattress and need help choosing which one to buy? We’ve got you covered! This article will discuss the factors and differences between foam and spring mattresses to help you define what you need to get quality sleep. Ready to discover the perfect mattress for you? Let’s explore!

What is a Foam Mattress?

According to Sleepopolis, foam mattresses utilise air trapped within aerated materials to provide support and resilience. Typically, these mattresses can be categorised into three main types: polyurethane, memory, and latex.

Types of Foam for Mattresses

Polyurethane Foam or ‘Polyfoam’

Polyurethane foam, or polyfoam, is often positioned as the uppermost layer in an innerspring mattress. It’s similar to memory foam; however, it lacks an added viscosity booster, meaning it’s much more bouncy and springy than memory foam.

Memory Foam

Memory foam is made from similar polyfoam materials with additives, which makes it denser and more tightly packed. Such mattresses can compress and sink under pressure, potentially creating challenges for individuals to move around on the mattress or get in and out of bed. Additionally, they tend to be more expensive, and some emit chemicals, contributing to a distinct odour.

Latex Foam

Foam latex is produced by introducing air into a sap-like substance, forming air bubbles. This mattress offers firm but bouncy support, evenly distributed across the entire bed. However, it tends to be more expensive and generally heavier. Similar to memory foam, these mattresses can trap heat. With a coil system, achieving breathability for the mattress becomes easier.

Does Sealy Use Foam in Their Mattresses?

Given the properties of foam materials, Sealy Singapore has developed mattresses focused on providing healthy spinal support and cooler sleeping comfort. While our brand only carries spring mattresses, we integrate advanced foam materials, including our specially designed ComfortCore®.  This signifies the presence of an additional supportive layer in the centre-third of the mattress, complemented by a combination of diverse comfort layers and foams. This thoughtful combination ensures various tactile experiences, catering to different preferences and providing optimal support for a well-aligned lower back during sleep. See the available range of mattresses to discover the distinct comfort and support you need.

What is a Spring Mattress?

Also known as ‘innerspring mattresses’, spring mattresses rely on metal springs to keep you comfortable when you sleep, especially since spaces between these coils allow free air to flow. This mattress type also has a supportive base, providing an extra soft layer and leveraging mattress comfort.

Types of Mattress Coil Systems

Like foam mattresses, spring mattresses have different types of materials or a wide variety of coil systems based on spring arrangement and pressure capability. We have outlined these below:

  • Offset Coils — These are a classic type of coils that are connected in a hinged way. This coil system also provides firmer support.
  • Pocket Coils — These are wrapped in fabric pockets and are great at isolating movement. Since the coils are independent, it reduces noise from movement.
  • Bonnell Coils These are the most traditional coil designs that you might think of for spring mattresses. They have hourglass-shaped springs and offer a bouncy and firm feel.
  • Continuous coils These are rows connected using helical wires, which provide a stable and supportive surface.

What Mattress Coil System Does Sealy Offer?

With Sealy’s years of experience crafting spring mattresses, we have formulated our own AlignSupport™ Titanium Coil system that provides maximum stability. With these spring placements, the AlignSupport™ Titanium Coil has more resilience to heat properties than other available brands. Most importantly, our coil material is made of Titanium Alloy to ensure superior strength, quality and performance. Compared to Pocketed Coils, our AlignSupport™ Titanium Coil offers more conformability and support with its six coils, compared to pocketed coils that are only joined in the middle by glue and can easily fall apart.

What is the Difference Between Spring Mattresses and Foam Mattresses?

With the factors we discussed, foam mattresses are a good option for minimising motion disturbances; however, they can be more expensive and may trap heat without a coil system. Meanwhile, spring mattresses can provide a more relaxed sleep experience. With ComfortCore®, you can enjoy a combination of diverse comfort layers and foams in our spring mattresses. Additionally, we use a unique product architecture principle comprising foams, and fibre fills for a more balanced comfort system. When used with our patented spring system, we ensure customers get the comfort they want and receive the correct support.
