Firm mattress topper Australia – firm mattress toppers are harder to find than soft ones, so I’m stoked to be able to share this awesome firm topper from Peacelily with you.

The Peacelily mattress topper made from latex which is no surprise, as this is a highly resilient and durable material making it the perfect solution for a firm mattress topper. An added bonus is that it’s also naturally cooling, so it won’t trap heat on those hot Aussie summer nights.

Best Firm Mattress Topper Australia- All The Peacelily Details

Firm Mattress Topper NZ - Peacelily Mattress Topper Close Up

Never heard of Peacelily? They’re an online mattress brand specializing in the best quality latex mattresses and toppers. They have a strong emphasis on customer care and keeping prices as low and transparent for their customers as possible (they’ve even been known to refund customers if they find a cheaper way to do things, these guys NEVER pass costs on to you if they can avoid it). It’s no surprise they’ve firmly established themselves as the best latex bedding brand in NZ and Australia with their quality products and customer focused attitude.

Unlike other latex mattress toppers, which can cost in excess of $1000, Peacelily firm mattress topper prices top out at $629 for a King size. This is even more remarkable given that a firm mattress topper requires a higher density material (read: a higher volume of the best quality latex you can find) which makes it more expensive to make.


  • Cover: Organic cotton (GOTS certified)
  • Core: 5cm natural latex core (one of the only brands offering you a firm option) – Peacelily sources their latex from Sri Lanka, which is known for producing the best quality latex in the world
  • Height: Overall height of 6cm
  • Firmness: Firm! Of course! The topper is also available in luxury plush.
  • Free shipping, usually dispatches in 1-2 days
  • 100 Night sleep trial (if you don’t like it, you’ll get a refund within that time, no hidden fees), meaning you can try this topper in the comfort of your own home without any obligation to keep it if it doesn’t fit your expectations
  • 10 Year warranty (this is LOOONG in the mattress topper space, where 3 -5 years is more the norm)
  • Price range: $369 – $629

Not only do Peacelily have fast and free shipping, they’re one of the very few brands I’m aware of that allows you to test their topper out in your own home (they’re definitely the longest at 100 nights). The value you’re getting here for natural latex AND these extras is actually unbeatable. Peacelily was a very easy choice to show you as the best firm mattress topper in Australia.

Other Mattress Toppers Available In Australia

If you’d like to shop around your options before you hit buy on Peacelily, here’s a summary of what you’ll find from other online brands.

Take note of the Emma mattress topper, one of the few dual firmness toppers on the market (but I think that overall, the firm Peacelilly topper is firmer).

Brand FirmnessMaterialHome Trial: Y/NWarrantyPrice
EmmaSoft one side
Firm the other
Memory foamY; 100 Nights10 Years$269-$349
EcosaPlushMemory foamN10 Years$330-$500
OctasmartMediumZoned memory foam + springsY: 80 Nights8 years$599-$1299
OnebedMediumZoned FoamNNone$300-$390

As you can see, most toppers are designed to be soft or medium, NOT firm. Emma is the only other brand offering a 100 night trial, and they’re the only other one with a firm option, so if Peacelily is looking pricey, Emma’s your next best alternative.

Firm Mattress Topper Australia – Your Questions Answered

Can You Make A Mattress More Firm With A Topper?

Yes you can: a firm mattress topper is one of the quickest and easiest ways to change the feel of your mattress, including making it firmer (with the right topper). If your mattress has good support but is just too soft for you, putting a firm topper on it can increase the firmness to a level that’s better for you.

Can A Mattress Topper Help A Sagging Mattress?

Yes it can. A topper will help provide a more even sleep surface, which will help you feel more supported. However, I want to warn you that if you’re buying a topper for mattress sagging, you may want to consider if your support base is actually strong enough or if you just need to get a new mattress because a topper may only be a temporary fix in this scenario.

How Do I Know If My Bed Is Too Soft?

You’ll feel it. Are you sleeping well? Do you feel like you sink into your mattress too much, or that it just doesn’t support you? Do you wake up with a sore back?
If you’re not sleeping well and you answer yes to any of those questions, the answer is probably yes, your bed is too soft.

Does Putting Plywood Under A Mattress Make It Firmer?

Yes it does. I do this on my own bed. I have a slat base and a heavy mattress can sag through the gaps between the slats if they’re too wide. Putting plywood is a cheap way to give your mattress a flatter base, which means more even support.
One note of caution: putting straight ply down won’t allow for any air circulation under your mattress, which can lead to mould issues. Drill some ventilation holes in it.

Do Mattress Toppers Work?

Yes they do. A good mattress topper can be a great investment that changes the comfort level of your bed for years to come without having to make the big investment of replacing other more expensive bed components like mattresses or bases.
