Sleep Firm vs Luxe vs Ultra: Which Firm Mattress Is Right for You?
By Michael Morrison, General Manager, Best in Beds - Published
Multi-store mattress retailer with showrooms in Campbelltown, Prospect and Warrawong, NSW
If you've already decided you want a firm mattress - a genuine, supportive, Firm 8 out of 10 - the next question is which of the three Sleep Firm models is the right fit for your body, your budget, and your sleep style. All three are Australian-made in Melbourne by Chiropedic, all three carry the same Firm 8/10 feel, and all three have been judged by BedBuyer as Australia's best firm mattress across three consecutive years (2024, 2025 and 2026). The differences come down to construction layers, comfort refinements, price point, and the type of sleeper each model is built for. This guide lays it all out so you can decide with confidence.
- Sleep Firm (Standard) - Best value, iconic Chiropedic build, from $1,099. Ideal for budget-conscious buyers who want the genuine BedBuyer-winning firm feel.
- Sleep Firm Luxe - Pillow-top exterior with a gel comfort layer on top of the firm core. From $1,899. Best for sleepers who want firm support but a softer initial feel at the surface.
- Sleep Firm Ultra - Premium construction with a higher coil count and denser foam layers. From $1,499. Best for heavier sleepers, couples, and anyone who wants the most robust long-term support.
- All three are Firm 8/10, GECA certified, Sensitive Choice approved, ASRF certified, 15-year warranty, and free delivery Australia-wide.
- All three are available to test in person at the Prospect, Campbelltown and Warrawong showrooms.
The Short Answer: Which Sleep Firm Is Right for You?
Most people who walk into a Best in Beds showroom wanting a firm mattress leave on the Sleep Firm (Standard). It is the original model, the one that set the benchmark, and for the majority of firm-mattress seekers - back sleepers, stomach sleepers, and those with chronic lower-back concerns - it does exactly what they need without unnecessary extras pushing up the price.
If you are a side sleeper who still prefers a firm feel, or someone who runs warm and appreciates gel-infused comfort at the surface, the Sleep Firm Luxe is worth the step up. The pillow-top layer softens the initial contact without degrading the underlying firm support - a balance that is genuinely difficult to engineer, and that Chiropedic has spent decades refining.
If you are above 100 kg, sharing a bed with a partner of significantly different weight, or simply want the most durable and premium build in the range, the Sleep Firm Ultra is the answer. The Ultra is built heavier from the inside out - more coil temper, denser foam base - and it shows in both the feel and the long-term edge-support.
What All Three Sleep Firm Models Have in Common
Before comparing differences, it is worth understanding what all three models share - because the common foundation is exactly why this range has dominated the firm-mattress category in Australia for three years running.
Every Sleep Firm mattress is manufactured at the Chiropedic factory in Melbourne - the same factory that has been producing orthopaedic-grade mattresses since 1968. That is over 55 years of production expertise, refined spring-tempering technology, and a refusal to outsource to lower-cost offshore operations. The result is a consistency of product that few Australian mattress brands can genuinely claim.
All three models sit at a Firm 8/10 feel. This is a meaningful number. Many mattresses sold as "firm" in Australian retail land closer to 6 or 6.5 out of 10 once the comfort layers compress. The Sleep Firm range is calibrated and independently verified at 8/10 - genuinely firm by the standard that physiotherapists and sleep specialists actually recommend for spinal alignment support.
All three carry: GECA (Good Environmental Choice Australia) certification; Sensitive Choice approval from Asthma Australia; ASRF (Australian Sleep Research Foundation) certification; a 15-year manufacturer's warranty; and free Australia-wide delivery. All three are also available on a no-obligation sleep trial - details vary by model (more on that below).
Sleep Firm (Standard) - The Original BedBuyer Winner
Who It's For
The Sleep Firm Standard is designed for back sleepers, stomach sleepers, and people who know they want a firm mattress without pillow-top softness at the surface. It is also the go-to for anyone recovering from lower-back injury or managing a long-term spinal condition where consistent, predictable support is more important than surface plushness. If you have always found medium-firm mattresses sink too far under your hips, this is likely your model.
Construction
The Standard uses Chiropedic's classic individually-pocketed spring system, tempered at the Melbourne factory to Chiropedic's proprietary specification. The comfort layers above the springs are deliberately restrained - firm foam with a quilted damask cover that gives a clean, traditional feel underhand. There is no gel layer, no latex, no pillow-top - just the honest spring-and-foam construction that earned the original BedBuyer award.
Pricing and Trial
The Sleep Firm Standard is priced from RRP $1,099 - representing exceptional value for an Australian-made mattress of this specification. It is backed by a 150 Night Sleep Trial, which includes both refund and exchange options. That is one of the most generous sleep-trial policies in the Australian market: 150 nights is five months, giving you multiple seasons to fully assess the mattress before the trial closes.
Sleep Firm Luxe - Pillow-Top Firm with Gel Comfort Layer
Who It's For
The Sleep Firm Luxe is built for the sleeper who knows they need firm support but finds the Standard's surface feel too stark at first contact. Side sleepers with a firm preference, sleepers who experience shoulder or hip pressure in the first weeks on a new mattress, and anyone who has been told by a health professional that they need firm support but finds straight-firm beds uncomfortable - the Luxe sits in that sweet spot.
It is also a strong choice for those who run warm during sleep. The gel-infused comfort layer at the surface draws heat away from the body more effectively than standard foam, making the Luxe the most temperature-neutral mattress in the Sleep Firm range.
Construction
The Luxe shares the same Chiropedic spring core as the Standard but adds a gel-infused comfort layer below a sewn pillow-top panel. The pillow-top is not the deep, sinking style common on plush mattresses; it is a shallow, structured panel that provides initial cushioning while the firm spring core ensures the body does not sink through to a suboptimal support depth. The cover upholstery is a step up in quality - a woven damask with a more premium hand-feel compared to the Standard.
Pricing and Trial
The Sleep Firm Luxe is priced from RRP $1,899. The sleep trial is a 100 Night Comfort Guarantee Exchange. Note the distinction: the Standard offers both refund and exchange; the Luxe (and Ultra) are exchange-only. This reflects the premium construction cost, but it also means you are still fully protected - if the Luxe is not right, you swap for another model in the range.
Sleep Firm Ultra - Premium Build for Heavier Sleepers and Couples
Who It's For
The Sleep Firm Ultra was developed in direct response to feedback from heavier sleepers - those above 100 kg - and couples where both partners want the firm feel but have notably different body weights. Standard pocket-spring mattresses, even very good ones, can exhibit premature edge softening and central support degradation when regularly supporting above-average bodyweights. The Ultra's construction addresses this directly.
Construction
The Ultra uses a higher-count, more heavily tempered spring system compared to the Standard and Luxe. The foam base layer is denser, providing better long-term resistance to core compression. Edge-support is reinforced at the perimeter, which is particularly noticeable when sitting on the side of the bed - a feature couples and those with limited mobility especially appreciate. The surface construction sits between the Standard's stark firmness and the Luxe's pillow-top softness - a structured, quilted comfort layer that provides moderate surface cushioning without the pillow-top profile.
Pricing and Trial
The Sleep Firm Ultra is priced from RRP $1,499, making it the mid-range price point - higher than the Standard but below the Luxe, despite having the most robust internal construction in the range. It carries the same 100 Night Comfort Guarantee Exchange as the Luxe, and the same 15-year warranty that covers all three models.

How to Decide:
Rather than a traditional flowchart, here are the five questions I walk every customer through in the showroom. Answer them in order and your model usually becomes obvious by question three or four.
1. What is your primary sleep position?
If you mostly sleep on your back or stomach, the Sleep Firm Standard is almost certainly the right choice - it provides the flattest, most consistent support surface for those positions. If you are primarily a side sleeper who still wants genuine firmness (not medium-firm), move to question two.
2. Do you run warm during sleep?
If yes, the Sleep Firm Luxe's gel comfort layer makes a meaningful difference. The gel-infused foam at the surface dissipates body heat more effectively than standard foam. If temperature is not a concern, move to question three.
3. What is your body weight, and are you sharing the bed?
If you are above approximately 100 kg, or if you and your partner have a body weight difference of more than 30–40 kg, the Sleep Firm Ultra offers the spring specification and foam density to maintain consistent, long-term support under those conditions. Lighter single sleepers can be confident in either the Standard or the Luxe.
4. What is your budget?
The Sleep Firm Standard starts from $1,099 and delivers genuine BedBuyer award-winning performance at that price. The Luxe and Ultra represent meaningful step-ups in construction - the Luxe at $1,899 and the Ultra at $1,499. None of these prices require a "luxury mattress" budget; all three sit in the accessible premium range for an Australian-made mattress of this quality.
5. How important is the sleep trial length?
If the maximum possible trial period matters to you - perhaps you are making the switch from a very different mattress type and want extra time to adjust - the Sleep Firm Standard's 150 Night Sleep Trial is the longest in the range and one of the longest in the Australian market. The Luxe and Ultra offer 100 nights.

Frequently Asked Questions
Is the Sleep Firm mattress actually firm, or just marketed as firm?
The Sleep Firm range is calibrated and independently rated at Firm 8 out of 10. BedBuyer's testing - which formed the basis of the 2024, 2025 and 2026 Best Firm Mattress award - uses standardised indentation force deflection (IFD) measurement to verify firmness claims. The Sleep Firm consistently delivers on its 8/10 rating, unlike many "firm" mattresses in retail that measure closer to 6 or 6.5/10 once comfort layers are accounted for.
What is the difference between the Sleep Firm Luxe and the Sleep Firm Ultra?
The Luxe prioritises surface comfort - it adds a gel-infused pillow-top comfort layer for sleepers who want some surface softness while preserving the firm support underneath. The Ultra prioritises structural performance - it uses a heavier spring gauge, denser foam base, and reinforced edge support for heavier sleepers and couples. If your concern is surface feel, choose the Luxe. If your concern is long-term support durability and weight capacity, choose the Ultra.
Which Sleep Firm mattress is best for lower-back pain?
For most back-pain sufferers who sleep on their back or stomach, the Sleep Firm Standard is the most direct recommendation - its flat, consistent support surface maintains spinal alignment without the pressure-relief distraction of a pillow-top layer. Side sleepers with back pain may find the Luxe's surface comfort layer reduces hip and shoulder pressure that can otherwise cause compensatory spinal curvature. Always consult your physiotherapist or chiropractor for personalised advice.
Can I return a Sleep Firm mattress if it doesn't suit me?
The Sleep Firm Standard includes a 150 Night Sleep Trial with both refund and exchange options - one of the most generous policies in the Australian market. The Sleep Firm Luxe and Sleep Firm Ultra include a 100 Night Comfort Guarantee, which is exchange-only (no refund). In all cases, you have meaningful protection and time to assess the mattress before any decision is final.
Are all three Sleep Firm models Australian-made?
Yes. All three Sleep Firm models - Standard, Luxe and Ultra - are manufactured by Chiropedic at their Melbourne factory. Chiropedic has been producing orthopaedic-grade mattresses in Australia since 1968. No offshore production, no outsourced assembly - every unit is made to their full specification in Melbourne.
How long does delivery take for a Sleep Firm mattress in Sydney?
Free next-day delivery is available for Queen, King and Double size Sleep Firm mattresses across Sydney and Wollongong when you order before 2 pm. All other sizes and locations across Australia receive free delivery within 7–14 business days. There is no delivery charge on any order in the Sleep Firm range.
Do I need a special base for a Sleep Firm mattress?
All three Sleep Firm models perform well on a slatted timber base (slats no more than 65 mm apart), a solid platform base, or an adjustable electric base. Avoid placing them directly on the floor for extended periods, as this restricts airflow. If you are unsure whether your existing base is appropriate, the team at any of our three showrooms - Prospect, Campbelltown and Warrawong - can advise.
