Feel & firmness
How firm is it, and who is it for?

All sizes follow Australian Standard mattress dimensions. Spring counts are for the Bonnell coil layer and increase with mattress size. Measurements are taken by hand and can vary slightly between shipments.
🧭Room clearance
Allow 60–75 cm around the piece to move comfortably; remember the frame footprint runs a few cm larger than the mattress.
📐Total height
Total height = base + your mattress, so a tall base plus a deep mattress can sit high — worth checking for getting in and out.
🚙Pickup vehicle
For free Rocklea pickup, a flat-pack fits most cars, but an assembled or oversized item needs a van, ute or trailer.

What's in the boxHow it arrives & unboxing
Sleep Essence is vacuum-compressed, rolled and boxed — one box per mattress. That is what makes it easy to fit in a vehicle and carry through a doorway or up a stairwell before you unroll it.
| In the box | 1 × mattress, vacuum-compressed and rolled |
|---|---|
| Boxed size (selected size) | 100 × 31 × 31 cm |
| Number of boxes | 1 |
| Assembly | None — unroll and let it expand |
Unbox where it will live
Carry the box into the bedroom and get it onto the base before you cut the wrapping. Once it starts expanding it is much harder to move.
Ready within hours
It starts expanding as soon as it is unwrapped and is generally ready to sleep on within a few hours. Like all rolled mattresses it can keep settling over the following days.
Don't re-roll or fold it
Once expanded it is not designed to be compressed again. Folding or bending it can damage the spring unit and is not covered by the warranty.
Easy to pick up
The boxed dimensions above make it straightforward to plan a pickup from our Rocklea warehouse in most vehicles with the seats down.
New foam and fabric can carry a faint manufacturing smell when first unwrapped. Airing the room for a few hours clears it.

Base & frame
What base does this mattress need?
The most common question we get on a mattress — and the one most listings never answer. The base underneath matters as much as the mattress itself, both for how it feels and for your warranty.
Bases this mattress suits
Use it on a solid or platform base, a slatted base with evenly spaced slats. The surface underneath needs to be flat and fully supportive across the whole mattress — no box spring required.
Slat spacing
As a general industry guide, slat gaps of more than about 7.5 cm can leave a mattress under-supported and may affect your warranty. If you are not sure what your base measures, send us a photo or call 07 3161 5415 and we will check it with you before you order.
Need a frame to match?
Every Australian size pairs with a frame of the same name — a Single mattress goes in a Single frame. Browse matching bed frames →
An unsupportive or incorrectly spaced base can affect both comfort and your warranty — see the warranty section below.
Warranty6-month warranty & your rights
Your mattress is covered against manufacturing faults in materials and workmanship for 6-month from the date of purchase.
What the warranty does not cover
- Damage caused by an unsupportive base — a sagging base, or slats spaced too far apart. See “What base does this need?” above.
- The gradual softening and body impressions that all comfort layers develop with normal use. This is expected settling, not a fault.
- Damage from misuse, standing or jumping on the mattress, bending or folding it, or moving it without proper support.
- A change of mind about comfort or firmness. Firmness is personal, so please try it at one of our showrooms before you buy.
No online trial — something better. Firmness is personal and no amount of online description settles it. Lie on this mattress at any of our five SE QLD showrooms — Rocklea, Virginia, Bundall, North Ipswich and Beenleigh — and buy it knowing exactly how it feels.
This warranty is in addition to your rights under Australian Consumer Law. Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure, and to compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.

FAQ
Questions we get asked
Bonnell springs are a traditional, interconnected coil system — a time-tested innerspring known for firm, even support, durability and good airflow through the mattress. In Sleep Essence the coils sit between felt pads, under a cushioned foam top.
It has a soft feel — around 4 on a 1 to 10 scale — with a cushioned foam top over a firm, supportive Bonnell coil base. That mix, along with its slim profile and value, makes it a practical choice for guest rooms, kids' rooms and spare beds. Firmness is subjective, so we'd suggest trying it in person at one of our five SE QLD showrooms.
Use it on a solid (platform) base or a slatted base with evenly spaced slats. An unsupportive base can affect comfort and may affect your warranty. If you are not sure what your base measures, send us a photo or call 07 3161 5415 and we will check it with you.
Yes. It is vacuum-compressed, rolled and boxed, which makes it easy to fit in a vehicle and carry through the home before you unroll it.
Once unboxed it starts expanding straight away and is generally ready to sleep on within a few hours. Like most rolled mattresses, it can keep settling over the following days.
No. The Sleep Essence is single-sided, with the comfort layers on top, so it is not designed to be flipped. Rotate it head-to-foot every few months to help it wear evenly.
Yes — its slim, boxed format and everyday value make it a popular choice for guest rooms, growing kids and spare beds.
Yes — and we would rather you did. We do not run an online sleep trial, because we think lying on a mattress beats reading about one. Sleep Essence is on display across our five SE QLD showrooms in Rocklea, Virginia, Beenleigh, Bundall (Gold Coast) and North Ipswich. Floor models can vary, so call ahead if you want a specific size. For change-of-mind and faults, see our warranty and returns policy — and note your rights under Australian Consumer Law always apply on top of any warranty.
