What Thickness Foam Should I Choose? One of the most common questions we receive at Foam for Home is, “What thickness foam do I need?” The answer depends on how the cushion will be used, the size of the cushion…

Choosing the best mattress topper can completely change how well you sleep. Whether your mattress feels too firm, too soft, or simply uncomfortable, the right mattress topper can add comfort, improve support, and extend the life of your mattress — without the cost of replacing it.
At Foam for Home, we supply Australian-made mattress toppers and foam solutions, helping customers across Australia find the right topper for their body, sleeping style, and comfort needs. This guide will help you decide which mattress topper is best for you, what thickness to choose, and which materials perform best.
A mattress topper sits on top of your existing mattress to adjust comfort and support. It can:
Add softness to a firm mattress
Improve pressure relief for hips, shoulders, and lower back
Help reduce motion transfer
Extend the life of your mattress
Improve sleep quality without replacing the mattress
For many people, a foam mattress topper is the simplest and most cost-effective sleep upgrade.
Side sleepers often experience pressure on their shoulders and hips. A softer foam mattress topper helps cushion these pressure points and promote proper spinal alignment.
A memory foam mattress topper is a popular choice for side sleepers because it contours to the body and evenly distributes weight.

If you suffer from lower back pain, the best mattress topper is one that offers support without sagging. Medium-firm foam provides spinal support while still allowing slight contouring.
A 50mm memory foam topper or custom foam sheet topper can help relieve pressure and support proper posture throughout the night.
If your mattress feels too hard, a topper adds comfort without replacing the mattress. Memory foam and convoluted foam are excellent options for softening firm beds.
A convoluted (egg crate) mattress topper is ideal if you want:
Improved airflow
A lighter feel
Extra surface comfort

Hot sleepers should avoid overly dense foam without airflow. A convoluted foam mattress topper allows better air circulation, helping regulate temperature throughout the night.
