The 30-Second Verdict: Quick Summary
Sleeping Duck is an Australian bed-in-box brand founded by engineers. It sells the customizable Mach II hybrid through its US store, run by Sleeping Duck Inc with a California-based service team. A bamboo cover, AirGrown foam and zoned pocket springs sit behind a 100-night trial and a 10-year warranty. It's best if you're a couple who wants a different firmness on each side. The big caveat is that US pricing and policy details are thinly published.

Chapter 02
Comfort and firmness: which mattress fits you
Why this matters to you: Feel names are the brand's words, not measurements. Use them to shortlist two or three beds, then let your body decide.
Side sleepers: choose Medium or Soft inserts for pressure relief, with split Half-Half resolving couple firmness splits. Back sleepers: Medium suits average-weight back sleepers wanting contour plus zoned coil support; Firm suits those wanting less sink. Stomach sleepers: Firm is the closest fit; heavier stomach sleepers should confirm support with the brand since weight guidance is not published.
Hot sleepers: bamboo cover and open AirGrown foam are positioned as airy, though some reviewers report sleeping warm. Heavier sleepers: thicker zoned coil unit with strengthened edges is positioned for support; firmness-by-weight guidance: Not published as of Sept 2026.

Which Sleeping Duck feel fits you?
Weight chart not yet researched
Weight and sleep position can change how a bed feels. We have not yet checked whether Sleeping Duck publishes a fit chart by body weight, so use a trial, where one is offered, to test the bed the way you sleep at home.
Neck: on your side, your nose should line up with the middle of your chest, not tip up or down.
Shoulders: your bottom shoulder should sink in. Tingling or a numb arm means the bed is too firm for you.
Lower back: on your back, slide a flat hand under your waist. A big gap means too firm; no room at all can mean too soft.
Hips: ask someone to look from the side. Hips lower than shoulders means the bed is too soft for you.

What do the warranties cover?
Why this matters to you: A warranty is only as good as its terms. Read the written terms and use a supported base, because the wrong frame can end coverage.
Buy page states a 10 Year Warranty; full warranty text including covered defects, indentation minimums, exclusions (stains, misuse, base requirements), claim documentation, and repair-versus-replacement remedies: not published as of Sept 2026. Retain receipt and follow care and base requirements; confirm claim steps with Sleeping Duck Inc before purchase.
Covered when the dip is deeper than Not yet researched, measured with nobody on the bed.
Strip the bed down to the mattress and wait a few hours so the top layers can recover.
Lay a straight edge (a broom handle or long level) across the dip, resting on the flat parts.
Measure from the edge down to the deepest point, then photograph the ruler for your claim.

Sleeping Duck vs. other mattress brands
Why this matters to you: A fair comparison needs the same facts for both beds. Line up price, trial and warranty for each one.
Versus Australian bed-in-box rivals such as Koala and Ecosa: Sleeping Duck differentiates on per-side customizable firmness with swaps rather than one fixed feel. Versus US bed-in-box hybrids: the split-firmness system and washable bamboo cover are the differentiators, while US rivals typically publish fuller spec sheets, firmer delivery networks and detailed warranty texts.
Detailed head-to-head specs, prices and policy comparisons: Not published as of Sept 2026.
Competitor details reflect published prices and specs on the date shown. Mattress brands may update prices and trial terms over time.
