The Sleep Republic Mattress is one of Australia's better-value pocket-spring hybrids: a medium-firm bed built on up to 2,500 individually wrapped springs, topped with gel-infused memory foam and a layer of ventilated natural latex. It aims to give you the contouring of foam with the support, bounce and airflow of springs. In this review we break down how it is built, how it feels, what it costs across every size, and who should (and should not) buy it.
Sleep Republic sells its hybrid entirely online and ships it compressed in a box, backed by a long 150-night trial and a 12-year warranty. That combination puts it squarely against the bigger names in the bed-in-a-box market, usually at a lower price than the household brands.
Sleep Society rating
Sleep Republic Mattress ★★★★½ 4.4/5
Firmness: Medium-firm (about 7/10) | Queen: $1,660 | Trial: 150 nights | Warranty: 12 years
How it scores
Build quality is strong for the price, with zoned springs, latex and a cashmere-blend cover; value is excellent against the big brands; comfort is a genuine medium-firm that suits most sleepers. Ease of use loses a little because a 31cm spring hybrid is heavy to move, but the 150-night trial and 12-year warranty are generous perks.
The bottom line
The Sleep Republic Mattress is the hybrid to buy when you want spring support and airflow without paying household-brand prices. The zoned pocket springs, natural latex and gel-infused foam deliver a supportive medium-firm feel that suits back and combination sleepers especially well, and the 150-night trial takes the risk out of buying online. It is firm for dedicated side sleepers who want deep pressure relief, and at 31cm and full of springs it is heavy to shift, but for balanced support and value it is an easy recommendation.
We assess every mattress on the same five criteria – quality, value, comfort, ease of use and perks – using the brand’s published construction, aggregated owner reviews from ProductReview.com.au and CHOICE, and hands-on assessment of the feel, cover and setup. We re-check pricing on the brand’s live page at each update.
The Sleep Republic suits back and combination sleepers who want firm, zoned support with a little contour, and value-minded buyers who want a genuine spring hybrid without paying premium-brand money. The springy, breathable build also makes it a strong pick for our heavier sleepers guide. Dedicated side sleepers who want a plush, deep-hug feel, and anyone who prefers an all-foam bed, may find it a touch firm – a softer option like the Ecosa may suit them better.

The Sleep Republic is a 31cm pocket-spring hybrid. From the top:
The zoned spring system gives different degrees of firmness under the shoulders, back and hips for spinal alignment. The mattress ships compressed in a box and expands within a few hours of unpacking.

The Sleep Republic is a true medium-firm, roughly 7 out of 10. The zoned spring core holds the spine level with a gentle top-layer contour, which suits back and stomach sleepers and heavier bodies well. Side sleepers who want a deep, plush hug may find it firm at the shoulders and hips.
Individually wrapped pocket springs move independently and the foam and latex layers absorb movement, so a restless partner is unlikely to wake you – strong motion isolation for a spring bed.
This is a cooler-sleeping build than dense all-foam beds: the spring core, ventilated latex and 3D spacer side panel all move air, while the gel-infused foam helps draw heat away from the surface.
There is a mild new-mattress smell on unboxing that clears within a day or two in a ventilated room.

Type: pocket-spring hybrid · Firmness: medium-firm (about 7/10) · Height: 31cm · Springs: up to 2,500 · Trial: 150 nights · Warranty: 12 years · Prices checked July 2026; confirm the current price before you buy.
The Sleep Republic Mattress starts at $1,020 for a single and runs to $2,080 for a super king, with a queen at $1,660. For a full pocket-spring hybrid with zoned springs, natural latex, gel foam, a 150-night trial and a 12-year warranty, that undercuts most of the household-name brands. Sleep Republic runs fewer big sales than some rivals because the everyday price is already keen, so check the live price before you buy.

Sleep Republic ships free across Australia, with next-business-day delivery to most metro areas on orders placed by 2pm (subject to stock). Other locations typically take 3–7 business days, and remote areas up to 14. The mattress arrives compressed in a box; you slide it onto your base, cut the plastic and it expands within a few hours. Returns during the trial are free and Sleep Republic arranges collection.
With a 12-year warranty and a durable pocket-spring core, natural latex and high-density foams, the Sleep Republic is built to last around the upper end of the typical 7–10 year mattress lifespan and beyond. Rotating it head-to-toe every few months and using a mattress protector will keep it in shape; the spring core and latex resist body impressions better than cheaper all-foam beds.
It is a true medium-firm, around 7 out of 10. That suits back, stomach and combination sleepers and heavier bodies; dedicated side sleepers who want a plush hug may prefer something softer.
Yes. The spring core, ventilated latex, gel-infused foam and 3D spacer side panel all move air, so it sleeps cooler than a dense all-foam mattress.
Up to 2,500 individually wrapped pocket springs depending on size, with 1,850 in a Queen, arranged in support zones for spinal alignment.
The Sleep Republic is already keenly priced for a hybrid. If you want an adjustable-firmness foam bed instead, the Ecosa is worth a look; for another spring hybrid, compare the Origin.
