Cutaway view of the Flex Hybrid Mattress showing its five internal layers

What's inside

Engineered layer by layer

Five layers working together across a 32cm profile — cushioning where you sink, support where you don’t.

1

The cover that keeps things fresh

Removable Tencel™ zip cover — breathable, dust mite–resistant, and easy to keep clean.

2

Flippable comfort layer, so you choose the feel

Cooling gel memory foam on one side, firmer support foam on the other. Unzip, flip, re-zip — done.

3

Transition foam, so you’re cradled, not stuck

Spreads your weight evenly between the comfort layers and the springs below.

4

7-zone pocket springs, so your spine stays aligned

Individually wrapped springs give firmer support under hips and gentler cushioning at shoulders.

5

Firm support base, so it lasts

High-density foam anchors the whole build, keeping every layer above it doing its job for years.

6

Reinforced edges, so you can use every centimetre

Foam-encased sides stop sagging and let you sleep (or sit) right to the edge.

32cm profile • 7 support zones • 2 firmness feels

Adjustable firmness

One mattress. Two feels.

Most mattresses make you pick a firmness and hope for the best. The Flex’s comfort layer has a different feel on each side — just unzip the cover, flip the layer, and zip it back up. No wrestling the whole mattress.

Medium-Firm side 6.5 / 10

PlushFirm

So side and combination sleepers get cushioned pressure relief at shoulders and hips.

Firm side 8 / 10

PlushFirm

So back and stomach sleepers get flatter, sturdier support all night.

Can’t decide? You don’t have to. Sleep on one feel for a few weeks, then flip the layer and compare — you’ve got 120 nights to find yours.

The nest&nook promise

Sleep on it for 120 nights

A few minutes in a showroom can’t tell you much. Four months of real sleep in your own home can — and if the Flex isn’t the one, we’ll make it right.

120-night risk-free trial

Not the one? We’ll arrange free pick-up and refund every cent. No fine print, no restocking fees.

15-year warranty

Built for the long haul — and backed for it. That’s more than 5,400 nights of covered sleep.

Free metro delivery

Rolled, boxed and delivered to your door — free across most Australian metro areas.

Interest-free instalments

Split it into 4 payments with Afterpay or Zip — sleep on it now, spread the cost.

Couple relaxing on the Flex Hybrid Mattress at home during their 120-night trial

★★★★★

“Started on the medium-firm feel, unzipped and flipped the layer after a month out of curiosity — turns out I’m a firm sleeper. My back has never been happier.”

★★★★★

“We run hot in summer and this is the first mattress that doesn’t. The zip-off cover goes straight in the wash. Genuinely clever design.”
