A memory foam topper on a memory foam mattress is exactly what it sounds like: an additional layer of memory foam placed on top of an existing memory foam mattress to fine-tune comfort, support, and temperature regulation. In simple terms, it’s a way to upgrade how your bed feels without replacing the entire mattress. Australians often use this combination to soften a mattress that feels too firm, extend mattress life, or add targeted pressure relief for hips, shoulders, and lower back.
Here’s why this setup is so popular: memory foam responds to body heat and weight, contouring to your shape. Adding a topper enhances that contouring, creating a more customised sleep surface that can reduce pressure points and improve overall sleep quality.
Is it a good idea to put a memory foam topper on a memory foam mattress?
Short answer: yes — if you choose the right topper thickness and density.
The main reason Australians love this combination is flexibility. A topper lets you adjust firmness and feel without the expense of buying a new mattress. However, doubling up on memory foam isn’t for everyone. Too much softness can reduce support, especially if the mattress underneath is already plush.
It works best when:
-
Your mattress is supportive but feels slightly too firm
-
You want better pressure relief without sagging
-
You’re extending the life of a quality mattress

Types of memory foam toppers Australians choose
Not all toppers are created equal. When pairing a memory foam topper on a memory foam mattress, these are the most common options in Australia:
1. Traditional memory foam toppers
Dense, slow-response foam that deeply contours to the body. Ideal for sleepers wanting maximum pressure relief.
2. Gel-infused memory foam toppers
Designed to disperse heat. A smart choice for Australian summers and warm sleepers.
3. Open-cell or ventilated memory foam toppers
Feature airflow channels or breathable structures to improve temperature regulation.
4. Zoned memory foam toppers
Provide varied support levels for shoulders, hips, and spine alignment.
Supportive brand mentions such as Florabelle Collection, Gallery Home, and Café Lighting & Living are often referenced in broader home comfort discussions, though House of Isabella Australia curates its own exclusive range tailored to Australian homes.
How thick should a memory foam topper be?
Thickness matters more than most people realise.
-
2–3 cm: Subtle comfort adjustment, ideal if your mattress is mostly right
-
5 cm: The sweet spot for most Australians — noticeable comfort without sinking
-
7–8 cm: Best for firm mattresses or heavier sleepers, but can feel too soft on plush beds
In simple terms, the softer your mattress already is, the thinner your topper should be.
How to choose the right topper for a memory foam mattress
Choosing the right memory foam topper on a memory foam mattress comes down to balance.
1. Check mattress condition
A topper won’t fix a sagging or worn-out mattress. It’s meant to enhance, not rescue.
2. Match firmness intelligently
-
Firm mattress → medium to plush topper
-
Medium mattress → medium topper
-
Soft mattress → thin or firmer topper
3. Consider sleeping position
-
Side sleepers benefit most from thicker, softer toppers
-
Back sleepers should prioritise spinal alignment
-
Stomach sleepers need thinner toppers to avoid lower-back strain
4. Think about heat
If you sleep warm, look for gel-infused or ventilated designs.
Benefits of using a memory foam topper on a memory foam mattress
Here’s why this setup keeps gaining popularity across Australia:
-
Enhanced pressure relief for joints
-
Improved spinal alignment
-
Reduced motion transfer for couples
-
Adjustable comfort without mattress replacement
-
Extended mattress lifespan
The main reason this combination works is that memory foam layers amplify each other’s strengths — when used correctly.
Common concerns (and honest answers)
Will it feel too soft?
It can — if you choose a topper that’s too thick or plush. Balance is key.
Will it trap heat?
Older memory foam did, but modern toppers with gel infusion and airflow design perform far better in Australian climates.
Does it affect support?
A topper adds comfort, not core support. The mattress underneath still does the heavy lifting.
