Feel & firmness
How firm is it, and who is it for?
The Sleep Rest King sits at soft on the scale — a cushioned, forgiving surface rather than a firm one. Here is exactly where it lands, and who tends to get on best with it.

Firmness is subjective — how firm a mattress feels varies with body weight and sleeping position. We recommend trying it in person at one of our five SE QLD showrooms before you decide.

What a Bonnell spring is
A Bonnell spring system is a traditional mattress spring made from hourglass-shaped coils that are linked together as a single unit — a long-established, value-friendly way to build a spring mattress. It gives a firm, responsive base under the Sleep Rest's soft, quilted comfort top. More detail is in our mattress buying guide.

🧭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.

Care instructions
Rotate, don't flip
Turn it head-to-foot every few months so it wears evenly. Sleep Rest is single-sided — the comfort layers are only on top.
Use a protector
A protector keeps the cover clean and guards against everyday spills. Staining is not covered by the warranty.
Let it breathe
Air it out from time to time and keep the room well ventilated.
Spot clean only
Use a damp cloth and a mild cleaner on marks. Never soak the mattress or use harsh chemicals.

What's in the boxHow it arrives & unboxing
The Sleep Rest King is vacuum-compressed, rolled and boxed — one box for the mattress. That is what makes it light and easy to carry through the home before you unroll it. We haven't published a boxed L×W×H for this model — call 07 3161 5415 if you need it to plan a vehicle pickup.
| In the box | 1 × mattress, vacuum-compressed and rolled |
|---|---|
| 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, settling to full shape 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
Being vacuum-compressed and light, it's straightforward to plan a pickup from our Rocklea warehouse in most vehicles.
New fabric and foam 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 King mattress goes in a King 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
Use it on a solid (platform) base or a slatted base with evenly spaced slats, so the mattress is supported evenly across its full size. 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. See our warranty policy.
A Bonnell spring system is a traditional mattress spring made from hourglass-shaped coils that are linked together as a single unit. It gives a firm, responsive and supportive base, and it's a long-established, value-friendly way to build a spring mattress.
It has a soft feel — around 4 on a 1 to 10 scale — with a quilted comfort top over a Bonnell spring core. As a simple, slim, value-friendly mattress, it's a practical choice for everyday use, a guest room or short-term needs. Firmness is subjective, so we'd suggest trying it in person at one of our five SE QLD showrooms.
Yes. The Sleep Rest is vacuum-compressed and roll-packed in a carton box, which makes it light and easy to carry through the home. Once unboxed it starts expanding straight away and is generally ready to sleep on within a few hours, settling to full shape over the following days.
Single (92 × 187 cm), King Single (106 × 203 cm), Double (137 × 187 cm), Queen (153 × 203 cm) and King (183 × 203 cm) — all Australian Standard dimensions, each its own live listing with its own stock.
No. The Sleep Rest has its quilted comfort top on one side, so it isn't designed to be flipped. Rotate it head-to-foot every few months to help it wear evenly.
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. The Sleep Rest is on display at our five SE QLD showrooms — Rocklea, Virginia, Beenleigh, Bundall (Gold Coast) and North Ipswich. For change-of-mind and faults, see our warranty and returns policy — your rights under Australian Consumer Law always apply on top of any warranty.
