By Michael Morrison, General Manager, Best in Beds

In short: King Koil is the only mattress collection in Australia recommended by the International Chiropractors Association (ICA). Manufactured exclusively by A.H. Beard in Padstow Sydney since 1980, every King Koil mattress is built on the patented Reflex Support System - individually-pocketed coils engineered for chiropractor-grade spinal alignment. Four MK2 models, three firmness levels each, all available with free delivery to Greater Sydney and the Illawarra and a 10-year guarantee.

The Reflex Support System - why chiropractors approve it

What sets every King Koil apart is the Reflex Support System. It's not a marketing name slapped onto a generic coil unit - it's a patented spring architecture refined across four decades of collaboration with chiropractors.

Here's how it works:

• Primary coils gently conform to your body's shape as you lie down, providing all-over support.
• Active coils - smaller springs interleaved throughout the support system - respond intuitively to extra weight, providing additional support where your body needs it (lumbar, hips, shoulders).
• Individually pocketed. Every spring sits in its own fabric pocket, which means each coil moves independently. Your partner rolling over doesn't transfer across the bed.
• Perforated casings on every spring pocket increase airflow through the support core - important for Sydney's humid summers.
• Performa Edge Support wraps the entire perimeter to create a stronger mattress edge and a larger usable sleeping surface (you can sit on the edge to put on shoes without feeling like the mattress is collapsing under you).

For couples, the practical effect is significant: Reflex responds independently to each sleeper, so a 95kg side sleeper and a 60kg back sleeper both get the support they individually need on the same mattress.

The four King Koil MK2 ranges - explained honestly

King Koil offers four current mattress ranges, all designated "MK2" (the latest revision). They sit on a tiered architecture - Premium at the top, Core for everyone else - and within each range you can choose Plush, Medium, or Firm comfort.

Here's the honest breakdown - what each range actually delivers, and who it's for.

King Koil Lexington MK2 - Premium flagship

Reflex Platinum Support System. This is the King Koil flagship - the only range in the line-up that combines all three of A.H. Beard's most advanced technologies: Micro Comfort Coils in the comfort layer (an extra mini-coil unit above the main support system for enhanced pressure relief), Gel Infused Latex (naturally antimicrobial, hypoallergenic, conforming), and Gel Infused Memory Foam (cool-to-touch, deep contouring). Layered with all three elements of the AeroComfort airflow technology: AeroQuilt, AeroFoam+, and AeroWeb.

Best for: Couples who want the best of both worlds - pressure relief and zoned support - and sleepers who run hot. The Micro Comfort Coils make the Lexington uniquely good at minimising partner disturbance while still feeling responsive.

King Koil Chamberlane MK2 - Core premium

Reflex Max Support System with VRS springs. The Chamberlane uses Variable Response Springs (VRS) - coils with additional turns at the top that dynamically respond to your weight and shape. Comfort layers feature Gel Infused Latex, Gel Infused Memory Foam, AND traditional Memory Foam, plus the full three-layer AeroComfort (AeroQuilt, AeroFoam+, AeroWeb).

Best for: Sleepers who want serious pressure relief and contouring without going to flagship pricing. The triple-foam comfort layer is genuinely lush.

King Koil Abelia MK2 - Core support specialist

Reflex Plus Support System. The Abelia incorporates more Active coils throughout the support system than the entry tier, so the hip and shoulder areas are gently cradled while the lumbar and waist get firmer support. Comfort layer features Gel Infused Memory Foam with its cool-touch gel benefit, plus AeroQuilt and AeroFoam+.

Best for: Side sleepers and anyone needing strong zoned support without the flagship-tier price. The Reflex Plus system genuinely shines here.

King Koil Kenwick MK2 - Core entry

Reflex Advance Support System. The Kenwick is the entry into the King Koil range and the most accessible price point - but it still includes Gel Infused Memory Foam and EvoFoam Comfort Foams, plus full Performa Edge support. AeroQuilt is included for breathability.

Best for: First-time premium mattress buyers, guest rooms, or anyone who wants ICA-approved support engineering on a sensible budget.

How to choose Plush, Medium, or Firm

Every King Koil range is available in three comfort levels. Here's our in-store rule of thumb - but if you can possibly visit a showroom, please do; firmness is the one thing photos and spec sheets cannot communicate.

• Plush - softer top, deeper contouring. Best for side sleepers who need extra shoulder and hip cushioning, or anyone under 75kg who finds firmer mattresses uncomfortable.
• Medium - the universally-comfortable middle ground. Suits most back sleepers, side sleepers over 75kg, and combination sleepers. If you're shopping with a partner who has different preferences, Medium is usually the right compromise.
• Firm - supportive surface with less sink. Best for stomach sleepers, heavier back sleepers, or anyone who specifically prefers a firmer feel for back support. Read our King Koil firmness guide for more detail.
