Bottom line: The A.H. Beard King Koil Chiro Reserve is an Australian mattress range with four advertised comfort levels, seven size choices and a coil-and-foam construction that includes a published specification of 125 active coils. Those details come from the manufacturer and its 2024 Harvey Norman brochure. No independent test, verified current price or model-specific performance score was established, so treat the Chiro Reserve as a mattress to try and price through a retailer rather than a product that can be ranked on unsupported claims.
This review separates documented specifications from questions you must verify before ordering: the exact feel, compatible adjustable base, delivered cost, delivery service, trial policy and return conditions.

What the Chiro Reserve is
The Chiro Reserve is an A.H. Beard King Koil mattress sold in Australia through retail partners. It is presented as part of the King Koil range and is available in firm, medium, plush and super firm versions. A.H. Beard lists seven size options from single through super king. The product page describes a layered design called AeroComfort, combining several foam and quilted elements with the Reflex Advance Support System.
Recommended Free Tools
“Chiro Reserve features the AeroQuilt element of our AeroComfort technology,” A.H. Beard says on its product page. That is a manufacturer description, not a result from an independent laboratory or sleep study. The same distinction applies to the model’s pressure-relief, cooling and support language: it explains the intended design, but it does not establish how the mattress will perform for every sleeper.

Construction and support system
AeroQuilt and AeroComfort
AeroQuilt is the named quilted element of the AeroComfort technology. Quilting affects the initial surface sensation when you lie down, while the materials beneath it determine how quickly you sink, how easily you change position and how much support you feel. The available product information identifies the technology names but does not publish complete layer thicknesses, foam densities or a certified firmness measurement.
Gel Comfort Foam
A.H. Beard describes Gel Comfort Foam as conforming to the body and intended to relieve pressure around the shoulders and hips. It also says the cooling gel is intended to help maintain temperature. These are design intentions stated by the manufacturer. They should not be read as independently proven reductions in pain, pressure or overheating. Body weight, sleeping position, room temperature, bedding and personal sensitivity can all change the experience.
Reflex Advance Support System
The 2024 Harvey Norman brochure identifies the Reflex Advance Support System as having 125 active coils. The brochure says primary coils provide all-over support and that the active coils add support in targeted areas. This is a published construction specification. It is not evidence of a particular spinal-alignment result, therapeutic effect or durability period.
Performa Edge Support
The product page describes Performa Edge Support as a high-density foam edge intended to maximise the usable sleeping surface. That wording indicates the purpose of the component, but no independent edge-compression measurement or roll-off test is available for this exact model. If you regularly sit on the edge, share the bed or use the full width, test the perimeter in a showroom rather than assuming the marketing description predicts your experience.
Published specifications versus independent evidence
| Item | What is documented | What is not established |
|---|---|---|
| Comfort choices | Firm, medium, plush and super firm are listed by A.H. Beard. | An independent firmness score or a standardized feel rating. |
| Coil system | The 2024 Harvey Norman brochure states 125 active coils in the Reflex Advance Support System. | Pressure maps, motion-transfer results, load ratings or longevity testing. |
| Foam features | AeroQuilt, Gel Comfort Foam and AeroComfort are named; the gel foam is described as conforming and cooling. | Foam density, layer thickness, temperature tests or independently measured pressure relief. |
| Edge construction | Performa Edge Support is described as a high-density foam edge intended to increase usable surface. | Compression, sitting or partner roll-off measurements. |
| Adjustable bases | A.H. Beard says the mattress is compatible with its adjustable bed bases. | A complete list of compatible base models and testing for every pairing. |
| Performance score | None published for this exact Chiro Reserve model in the available material. | Independent comfort, support, durability, cooling or motion-isolation results. |
This separation matters because a coil count or a feature name cannot, by itself, tell you whether the mattress suits your body. The missing measurements are reasons to test the exact comfort version and obtain written retailer terms, not reasons to assume the mattress is either excellent or poor.

Comfort options: choosing the feel
Firm
The firm version is the likely starting point for sleepers who prefer little sink and a more level surface. Do not equate the label with a clinical recommendation. A firm mattress can feel different depending on body weight, sleeping position and the base beneath it. Spend enough time lying in your usual position to check whether your shoulders and hips can settle without a pressure hotspot.
Medium
Medium is commonly chosen by couples who need a compromise, but the word is not a regulated measurement. If partners have different weights or positions, each person should test the surface on both sides. Ask the retailer whether the displayed model is the same version and cover specification as the one being ordered.
Plush
Plush adds a softer initial feel and may allow more contouring at the shoulders and hips. Check whether you can turn comfortably and whether your pelvis feels level when lying on your side or back. A soft showroom impression can change after several minutes, so remain on the mattress rather than making a decision after a brief sit.
Super firm
Super firm is intended for shoppers who want the least surface give among the listed choices. It may feel too hard for side sleepers who need more shoulder and hip accommodation. The label alone does not establish a medical benefit, so use your own comfort and alignment observations as the decision criteria.
Sizes and dimensions
A.H. Beard lists seven sizes from single through super king. The supplied product information gives dimensions in millimetres for queen and king:
Rank #3

- Flawless 4K@60Hz Video with HDMI: Delivers exceptional clarity and smoothness with its 4K@60Hz HDMI port, making it ideal for high-definition presentations and entertainment. (Note: Only the HDMI port supports video projection; the USB-C port is for data transfer only.)

- What You Get: Anker USB-C Hub (7-in-1), welcome guide, 18-month warranty, and our friendly customer service.
| Size | Published dimensions | Buying note |
|---|---|---|
| Single through super king range | Seven sizes are listed; dimensions for each size are not stated in the available product details. | Confirm the exact mattress dimensions and required clearance with the retailer. |
| Queen | 2030 × 1530 mm | Check that the internal platform, protector and sheets match these measurements. |
| King | 2030 × 1830 mm | Measure doorways, stairs and the bed frame before delivery. |
Do not order from a generic “queen” or “king” assumption if your existing frame uses a non-standard size. Ask for the packed dimensions as well as the finished mattress dimensions when access is difficult. Retailers can also confirm height, which is not stated in the supplied model information and affects headboards, sheets and the ease of getting in and out of bed.
Adjustable-base compatibility
A.H. Beard states that the Chiro Reserve is compatible with its adjustable bed bases. The statement does not identify every compatible base model, hinge arrangement or weight limit. Before buying, provide the retailer with the exact base model number and ask for written confirmation that the selected Chiro Reserve size and comfort version are approved.
Also confirm the practical details: whether the mattress can be used on the base without a separate foundation, whether the warranty requires a particular base, and whether delivery teams will assemble both items. A generic adjustable base should not be assumed to be covered merely because the mattress is described as adjustable-base compatible.
Guarantee, returns and post-purchase changes
Ten-year guarantee
The model page states a ten-year guarantee for the original purchaser against faulty workmanship and materials. A guarantee is not the same as an unconditional replacement promise. Read the linked guarantee terms for exclusions, proof-of-purchase requirements, transport responsibilities, base requirements and how claims are assessed. Keep the invoice and record the model, size and comfort level supplied.
Change-of-mind policy
A.H. Beard says it does not offer change-of-mind returns. That makes the retailer’s written policy especially important. A store may have its own exchange, comfort-trial or clearance rules, but those terms should be confirmed before payment rather than inferred from the manufacturer’s guarantee.

Changing the support level
The product information says support levels may be adjusted after purchase for a nominal fee. Ask what “adjusted” means in practice: whether the mattress is exchanged, modified, collected or replaced; how the fee is calculated; and how long you have to request the change. Obtain the answer in writing because this option does not automatically create a free trial or a change-of-mind return.
Price, retailers and availability
A.H. Beard directs shoppers to retail partners instead of publishing a current direct-to-consumer price for this model on the product page. Harvey Norman and Forty Winks are among the named retail partners, and the available collections can vary by retailer. No verified current price for the exact Chiro Reserve, size and comfort level was established.
Request a complete delivered quotation that identifies:
- the Chiro Reserve version, size and comfort level;
- mattress price, delivery and installation charges;
- old-mattress removal and recycling fees;
- the expected dispatch and delivery window;
- the retailer’s trial, exchange and return conditions;
- warranty registration and claim procedures; and
- whether the quoted amount is a recurring promotion or a one-time sale price.
A.H. Beard’s shop page describes Soft Landing mattress pickup in parts of New South Wales, the Australian Capital Territory, Melbourne and Perth for a stated fee range of $55–$77. The page was undated when accessed in 2026, so verify that your postcode is covered and that the fee still applies. Do not treat pickup as included in a retailer’s mattress quotation unless it is listed explicitly.

- Identify the exact model. Confirm that the display is the King Koil Chiro Reserve, not another King Koil mattress with a similar cover or name.
- Match the comfort version. Record whether the floor sample is firm, medium, plush or super firm. A different label can feel substantially different.
- Use your normal sleep positions. Lie on your back, side and stomach if those are positions you use at home. Allow several minutes for the surface to settle.
- Check pressure and alignment. On your side, look for shoulder or hip pressure; on your back, check whether your lower back feels unsupported or overly arched. These are personal observations, not medical tests.
- Test movement. Roll, sit up and get out of bed. Note whether the surface makes position changes easy and whether the edge feels stable.
- Test with your partner. Have one person turn or sit while the other remains still. This gives you a practical impression of disturbance, but it is not an independent motion-transfer measurement.
- Ask about the base. If you plan to use an adjustable base, test or verify the exact pairing before ordering.
- Photograph the label and quote. Keep evidence of the model, comfort level, size, price and promised services so the delivered item can be checked.
Questions to ask before paying
- What is the exact finished size and mattress height for this SKU?
- Is the quoted item manufactured for the Australian market and labelled Chiro Reserve?
- Which adjustable-base model is approved for this size?
- Does the retailer provide a sleep trial, exchange or comfort adjustment, and what fees apply?
- Who pays collection or freight if a warranty issue occurs?
- Is old-mattress removal available in my postcode, and is it included in the quote?
- What happens if the ordered comfort level is unavailable?
- How long will delivery take, and will the team carry the mattress upstairs?
How it compares with alternatives
No independent Chiro Reserve comparison was established, so a responsible comparison should use verifiable terms rather than a guessed ranking. Put the Chiro Reserve and each alternative on the same quote and test sheet:
Best Value

| Comparison axis | What to record for the Chiro Reserve | Why it affects the decision |
|---|---|---|
| Comfort and feel | Firm, medium, plush or super firm; your observations after several minutes. | Labels are subjective and determine whether the surface suits your positions. |
| Size | Queen 2030 × 1530 mm; king 2030 × 1830 mm; verify other sizes. | Ensures the mattress fits the frame and room access. |
| Support construction | Reflex Advance Support System with 125 active coils, plus the named foam and edge elements. | Documents construction without pretending it proves comfort or durability. |
| Edge and partner behaviour | Your showroom observations; no independent model-specific measurements are available. | Important for couples and people who use the perimeter. |
| Adjustable-base fit | Manufacturer says compatible with its bases; exact pairing must be confirmed. | Prevents an incompatible setup or warranty dispute. |
| Trial and returns | No manufacturer change-of-mind returns; obtain retailer terms. | Affects your risk if the feel is wrong at home. |
| Guarantee | Ten years for the original purchaser against faulty workmanship and materials, subject to terms. | Clarifies what protection exists and what exclusions may apply. |
| Delivered price and availability | Not established; request a current retailer quotation. | Promotions, freight and removal can change the real cost. |
This framework keeps documented construction separate from the outcomes that require personal testing or independent measurement. It also prevents a price from another King Koil model, or a score from a different mattress, from being transferred to the Chiro Reserve.
Who should consider it
The Chiro Reserve is worth considering if you want several firmness choices, need a mattress sold through Australian retailers, or plan to pair it with an A.H. Beard adjustable base after confirming the exact model. The seven-size range may also help when replacing an existing King Koil-sized mattress, provided the measured dimensions match.
It is a poor fit for a buyer who needs a guaranteed home trial, a published independent performance score, a transparent direct price or a fully specified layer-by-layer construction before purchase. The manufacturer’s no-change-of-mind position means you should be confident in the comfort level and retailer policy before committing.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsLimitations of the available evidence
The available material does not establish an independent test score, verified current price, complete compatible-base list, standardized firmness rating, motion-transfer result, edge-support measurement, cooling test or durability result for the exact Australian Chiro Reserve. A forum discussion about finding a commercial King Koil mattress in the United States does not identify this model and cannot be used as evidence about its availability, equivalence or performance.
Those gaps do not make the mattress unsuitable; they define what remains your responsibility to verify. Use the exact model label, test the chosen feel, obtain written delivery and return terms, and keep the guarantee documentation.
