Half-half mattresses firmness

One bed. Two firmnesses. Zero compromise.

From Karl van Lieshout, Founder

The problem with compromise

Over the years, I've heard from many couples who are tired of sleepless nights.

I get this question every week. One partner sinks, the other feels like concrete. One partner is too heavy for the existing mattress, so they sink right through and wake up with back pain. The other side feels too firm. This is the problem every couple knows.

Every Ausbeds mattress ships with a felt layer hidden between the springs and comfort layers. Move the felt above the springs and it firms up. Move it below the springs and it softens. The half-half is simply positioning the felt differently on each side of your bed. You do it yourself at home in about 15 minutes. No special order, no factory work, no technician visit. Just unzip the cover, move the felt on one side, zip it back up. Done.

Customised comfort layer by layer

Every Ausbeds mattress already has everything you need for a half-half setup. The felt layer inside your mattress controls firmness. Position it above the springs for firmer, below for softer. Just do it differently on each side and you've got two firmness levels in one bed. It takes about 15 minutes at home.
Ultimate Support

DIY at home, 15 minutes

Unzip the cover, lift the comfort layers on one side, and move the felt to where you want it. Above the springs for a firmer feel, below for softer. That's it. No tools, no help needed. Your partner can sleep on Level 9 while you sleep on Level 8. If it's not right, just move it again.

Personalised Firmness

Independent Comfort Layers

The comfort layers — latex and microsprings — sit on top and stay the same across the whole mattress. The only thing that changes is where the felt sits underneath. Both partners get the same premium materials, the same smooth surface, the same cover. There's no seam or ridge in the middle because nothing is split. You're just adjusting one layer inside.

How to Order
No more partner disturbance

The "no gap" engineering

The biggest failure of split king and other mattress sizes designed for different firmness levels is the gap or ridge in the middle. When you simply place two different firmness pieces on top of pocket springs, they form a hump in the middle, and the middle is softer.

One mattress, no gap, no compromise

  1. The springs run continuously across the full width of the mattress — no cuts, no joins.
  2. The felt layer is simply positioned differently on each half. Above the springs on one side, below on the other.
  3. A unified Tencel cover holds everything in place, so the surface feels completely seamless.

A single mattress, 2 different feels

The result is a single, cohesive mattress that looks and feels like one bed, but delivers two different firmness levels. There's no seam, no ridge, no gap in the middle. Customers report that it's "incredibly seamless." Because the springs and comfort layers are continuous, you get zero partner disturbance from construction — just individual support from a simple felt adjustment.

Built for two

How the half-half system delivers better sleep

The core benefit is getting proper spinal alignment and eliminating uncomfortable pressure points. Here are a few real-world configurations:

1. The weight difference

One partner is 95kg, the other is 60kg. The heavier partner wants more support, the lighter one wants it softer.

  • His side: Move the felt above the springs. Firmer feel, more support (Level 9).
  • Her side: Move the felt below the springs. Softer feel, more cushioning (Level 8).

Result: He gets firm support without bottoming out. She gets pressure relief without feeling like she's on a rock. Took 15 minutes on a Saturday morning.

2. Different sleep positions

One partner sleeps on their stomach, the other on their side. Completely different needs.

  • Stomach sleeper's side: Felt above the springs for a firm, flat surface that keeps the spine straight.
  • Side sleeper's side: Felt below the springs for a softer feel that relieves pressure on shoulders and hips.

Result: Both sleep in their preferred position without waking with pain. And if anything changes, just reposition the felt. No cost, no booking, no waiting.

The trial period

Adjusting your sweet spot

We know that choosing the starting firmness levels can be difficult. That's why we offer a 7-month trial to find the perfect mattress configuration.

Felt repositioning is free and unlimited. Move it yourself at home anytime, as many times as you want. That covers most adjustments.

Need a bigger change? Within your 7-month trial, you get 2 free component swaps where we come to you and swap the springs or latex. If your needs change years later due to injury or aging, we can swap components on just one side. No need to buy a whole new bed.

Example

You start on Level 9. Too firm? Move the felt below the springs yourself — that's Level 8. Still not right? We'll swap the springs or latex for free during your trial. You have 7 months to find your sweet spot on each side.

Pricing & Logistics

How to order

For a half-half mattress with different spring units on each side, the cost is $650 on top of the mattress price. This is only available for the Double, Queen, and King-size mattresses.
Step 1

Order for the heavier partner's weight

We match spring tension to the heavier partner. This is how every Ausbeds mattress is ordered — the half-half part comes after delivery.
Step 2

Both happy? You're done

Most couples within 40kg of each other sleep well on the same firmness. If you're both comfortable, there's nothing else to do.
Step 3

One partner wants softer? 15-minute fix

Unzip the cover on their side, move the felt from above the springs to below. Firmer to softer, just like that. No tools, no help needed.
Step 4

Change your mind? Change it back

The felt moves in either direction, as many times as you want. No cost, no booking. Your mattress adapts to you, not the other way around.
