Choosing the Right Double Mattress
A double bed mattress earns its place by being the practical middle size — and choosing well comes down to who's sleeping on it and how. This guide covers who a double suits, the builds we stock, how to land on the right firmness, and how it compares to the sizes either side of it.
Who a double mattress suits best
- Solo adults who want room: a generous, spread-out sleep for one without committing the floor space a queen needs.
- Couples in compact bedrooms: the practical choice when a queen simply won't fit the room — cosy for two, and a common pick for smaller apartments and older Queensland homes.
- Guest rooms: comfortable for one or two visitors without over-investing in a spare room.
- Teen upgrades: the step into a proper grown-up bed once a single or king single has been outgrown.
One honest note: a double is wider than a single but the same length (188 cm). If you or your teen need more legroom rather than width, a king single (203 cm long) or a queen is the better fit — we'd rather point you to the right size than sell you the wrong one.
Double mattress types we stock
The right build depends on the sleeper and on the climate — Brisbane and Gold Coast nights run warm and humid, so breathability does real work here.
- Pocket spring: individually-wrapped springs that move independently — best for minimising partner disturbance, which matters most at double width.
- Memory foam & cooling gel: contours to relieve pressure points; gel-infused layers sleep cooler through humid South-East Queensland nights.
- Bonnell spring: a firmer, value innerspring — the most budget-friendly way into a double.
- Pillow top, Euro-top & memory-foam hybrid: a plush comfort layer over a supportive core for cushioned softness without losing structure.
- Mattress in a box: compressed and boxed so it fits in a hatchback or SUV and sets up in minutes.
- SleepMaker: a trusted name brand, available in double for shoppers who prefer a recognised manufacturer.
Firmness — find your feel
Firmness is personal, but your sleeping position is the best starting point: side sleepers usually want a softer surface that lets hips and shoulders sink in; back and stomach sleepers usually need firmer support to keep the spine aligned.
- PlushSoft, cushioned surface — suits side sleepers and lighter builds. See our soft & plush range.
- MediumThe middle ground — broad appeal, good for combination sleepers. See medium firm.
- FirmSolid, supportive feel — suits back and stomach sleepers. See our firm range.
- Extra firmMaximum support for those who want minimal give. See extra firm.
Double, king single or queen?
A double is 138 × 188 cm — wider than a king single (107 × 203 cm, which is narrower but 15 cm longer) and narrower and shorter than a queen (153 × 203 cm, the standard couples size). Choose a double when you want more width than a single without a queen's footprint; choose a king single for length over width; choose a queen when two people want proper room.
Why buy your double mattress from A2Z
The A2Z Furniture is a family-run Australian business established in 2013. Here's the part the online-only brands can't offer: instead of guessing from a screen and waiting out a trial period, you feel the exact double mattress in person first — across five South-East Queensland showrooms: Rocklea, Sandgate, Bundall, North Ipswich and Beenleigh. Stock is held in our Brisbane warehouse with pick-up available seven days a week, plus Free Local Delivery on eligible orders from Rocklea. Every mattress carries a manufacturer's warranty (from 12 months, with longer periods on premium models) — see our warranty policy — and you can spread the cost interest-free with Afterpay, Zip, Humm and Latitude. You'll also find verified customer reviews on the individual product pages to help you compare. Prefer to talk it through? Call our team on 1300 781 990.
Double Mattress FAQs
What are the dimensions of a double mattress in Australia?
An Australian double mattress is 138 × 188 cm — wider than a single but the same length. For a full comparison of every Australian size, room-size requirements and a double-vs-queen breakdown, see our Australian bed size guide.
How much does a double mattress cost at A2Z?
Double mattresses start from around $139 for a basic Bonnell spring model, rising with the type and comfort layers — pocket spring, memory foam, pillow top, Euro-top and memory-foam hybrid. The product grid above shows current pricing for each. Interest-free payment is available through Afterpay, Zip, Humm and Latitude.
Is a double mattress big enough for two people?
A double comfortably sleeps one adult with room to spread out, and works for two in a cosy setup — at 138 cm wide it's snugger than a queen. Couples who want more personal space should consider a queen; for a solo sleeper a double is generous.
What's the difference between a double and a queen mattress?
A double is 138 × 188 cm; a queen is 153 × 203 cm — wider and 15 cm longer. Browse the queen range or compare all sizes in our bed size guide.
Do you have memory foam or cooling double mattresses?
Yes. Our memory foam range includes gel-infused options that sleep cooler — well suited to warm, humid Brisbane and Gold Coast nights.
Can I see and test double mattresses in person before I buy?
Yes — and we'd encourage it. You can try the exact double mattress at any of our five South-East Queensland showrooms: Rocklea, Sandgate, Bundall, North Ipswich and Beenleigh. Feeling the firmness in person beats guessing from a screen.
Do you deliver double mattresses, or can I pick one up?
Both. Stock is held in our Brisbane (Rocklea) warehouse with pick-up seven days a week, and Free Local Delivery is available on eligible orders from Rocklea — see our delivery details. Mattress-in-a-box models are especially easy to transport yourself.
