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.

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 Double mattress goes in a Double frame. Browse matching bed frames →
An unsupportive or incorrectly spaced base can affect both comfort and your warranty — see the warranty section below.
Warranty10-year warranty & your rights
Your mattress is covered against manufacturing faults in materials and workmanship for 10 years 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. 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.
Flat and full-size. Unlike a rolled mattress, it is not compressed or boxed — it arrives ready to sleep on straight away, with no unrolling or waiting for it to expand.
It's a firm foam border that wraps around the pocket spring unit. It reinforces the sides of the mattress, so you get more supportive edges, a sturdier seat when you sit on the edge of the bed, and the full width as usable sleeping surface.
It has a firm feel — around 7 on a 1 to 10 scale — with deep comfort layers over a foam-encased pocket spring core. Firmness is subjective, so we'd always suggest trying it in person at one of our five SE QLD showrooms.
No. Sleep Serenity is single-sided, with the quilted comfort top on one side, so it is not designed to be flipped. Rotate it head-to-foot every few months to help it wear evenly.
Double (137 × 187 cm), Queen (153 × 203 cm) and King (183 × 203 cm) are currently stocked.
Yes. The springs are individually wrapped, so they move largely on their own rather than as one connected unit. That helps limit the disturbance you feel when someone shifts or gets in and out of bed.
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 Serenity 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.
Full detailsSleep Serenity Pocket Spring Mattress — full product details
The Sleep Serenity is a deep pocket spring mattress built around a 21 cm, 2.3 mm-gauge spring core wrapped on every side in 7 cm of high-density foam — giving supportive edges and the full width as usable sleeping surface — while layers of polyester fibre, comfort foam and high-density foam cushion the top under a 400 g knitted cover, for 32 cm total. Our mattress buying guide covers the firmness, spring structure and materials in more detail.
Available in Double, Queen and King. Its firm, 7 out of 10 feel suits sleepers who want a substantial, well-supported surface, and the individually wrapped springs help limit partner disturbance for couples. Sleep Serenity arrives flat and full-size — not rolled or compressed — and works on any solid (platform) or slatted base.

See our bed frames. Or come and lie on it at one of our five South-East Queensland showrooms in Rocklea, Virginia, Beenleigh, Bundall and North Ipswich.
