What about pre-order or made-to-order mattresses?
A number of premium ranges - including selected Yinahla and Sealy Posturepedic models - are made to order in Australia. These products will display a "Pre-order: usually ships in X weeks" badge on the product page. Pre-order items do not qualify for next-business-day delivery - your delivery window starts when the mattress is finished and ready to leave the factory.
Our entire Eco Kids, Sleep Firm and Morrison ranges are held in stock at our own warehouse and ready to dispatch the same day, so they all qualify for free next-business-day delivery when you order before 2pm.
If timing is critical, give us a call on 1300 399 676 or email dream@bestinbeds.com.au and we'll confirm what's ready to dispatch tomorrow.
What's included in free next-day delivery?
- Door-to-door delivery to a single, ground-floor entry point at the address you provide.
- Our delivery drivers call you 1 hour before they arrive.
- Delivered by a Best in Beds driver direct from our own warehouse - not a third-party courier.
Optional add-ons (paid)
- White-glove delivery + setup: Bring your new mattress upstairs, place on your bed base, and remove all packaging.
- Old mattress removal: We'll take your old mattress away for responsible recycling at the time of delivery.
Add-ons can be selected by replying to your delivery confirmation email.

Live outside the postcodes listed below? No worries - we still ship anywhere in NSW and across Australia. Standard delivery times and freight charges may apply at checkout based on your postcode. For a quote before you order, email dream@bestinbeds.com.au with the product and your delivery address.

MATTRESS DETAILS
The Lexington MK2 is King Koil's premium flagship - and the only mattress in the line-up that combines all three of A.H. Beard's most advanced sleep technologies. Built on the Reflex Platinum Support System with Micro Comfort Coils above the main spring unit, layered with Gel Infused Latex AND Gel Infused Memory Foam, and topped with the full three-layer AeroComfort airflow system. International Chiropractors Association approved. Australian-made in Padstow Sydney. 10-year guarantee.
Why Lexington sits at the top
The headline difference is the Micro Comfort Coils - an additional mini-coil unit set into the comfort layer above the main support springs. This is the only King Koil in the current range to include them. The effect is meaningful: where the main Reflex Platinum springs handle deep zonal support, the Micro Coils respond independently to micro-movements at the surface - reducing partner disturbance while keeping the mattress responsive, not sluggish.
Above the Micro Coils, Lexington uses both Gel Infused Latex (naturally antimicrobial, hypoallergenic, gently conforming) and Gel Infused Memory Foam (cool-to-touch, deep contouring for pressure relief). Most mattresses at this price use one or the other; Lexington uses both, in distinct layers. Wrapped in the full three-layer AeroComfort airflow system - AeroQuilt, AeroFoam+, and AeroWeb - to keep the mattress breathing in our humid Sydney summers.
Reflex Platinum Support System
Reflex Platinum is King Koil's most advanced spring architecture:
- Primary coils conform to your body shape across the full surface.
- Active coils - smaller springs interleaved through the support core - respond to extra weight in your lumbar, hips, and shoulders.
- Individually pocketed - every spring sits in its own fabric pocket so coils move independently.
- Perforated pocket casings increase airflow through the support core.
- Performa Edge Support wraps the perimeter for a stronger usable edge.
What's inside the Lexington MK2
- ✓ Reflex Platinum Support System - Primary + Active coils, individually pocketed
- ✓ Micro Comfort Coils - extra mini-coil layer above the main springs
- ✓ Gel Infused Latex - natural latex with cooling gel infusion
- ✓ Gel Infused Memory Foam - cool-to-touch contouring memory foam
- ✓ AeroQuilt - breathable quilted top layer
- ✓ AeroFoam+ - open-cell foam for vertical airflow
- ✓ AeroWeb - final airflow layer at the base of the comfort stack
- ✓ Performa Edge Support - reinforced perimeter
Choose your comfort level
- Plush - softer top, deepest contouring. For side sleepers and lighter sleepers.
- Medium - most popular, balanced support and comfort. For most couples and combination sleepers.
- Firm - most supportive surface. For stomach sleepers, heavier back sleepers, or anyone who prefers a firmer feel.
Read our King Koil firmness guide if you're unsure, or visit any Best in Beds showroom to try each.
Best for
Couples who want serious pressure relief AND zoned support without compromise. Sleepers who run hot (Lexington's triple-foam comfort stack is the coolest in the King Koil range). Anyone with back, hip, or shoulder issues who's read about Reflex Platinum and Micro Comfort Coils and decided the flagship is worth it. If you're cross-shopping with imported luxury brands at $6,000–$10,000, Lexington is honestly the right call - same engineering, Australian made, half the price.
