Choosing the Right Bonnell Spring Mattress
A Bonnell spring is the original innerspring design — hourglass-shaped coils tied together into one connected support unit. It isn't trying to be the most advanced mattress in the room; it's trying to be a solid, breathable, dependable bed at the lowest sensible price. Knowing exactly what it does well, and where it doesn't, is the fastest way to tell whether it's the right call for your situation.
Who a Bonnell spring mattress suits best
- Guest rooms and occasional beds: a comfortable, supportive bed for visitors without spending on features that get used a few nights a year.
- Kids' and teens' rooms: firm, durable and inexpensive enough to replace as they grow.
- Budget-first buyers: the lowest entry point we stock — a genuine, brand-new mattress with a warranty, not a compromise on safety or build.
- Anyone who likes a firm, breathable bed: the connected coil gives even, firm support, and the open structure breathes exceptionally well — a real plus through a humid Brisbane or Gold Coast summer.
…and who might prefer a different type
The honest limitation of a connected-coil design is movement: because the coils are linked, one person turning over carries across the bed more than on an independent-coil mattress. If you share the bed and partner disturbance matters, a pocket spring (individually-wrapped coils) is worth the step up. And if you want contour and pressure relief rather than firm, flat support, look at memory foam. There's no point overspending on a Bonnell's strengths if those aren't what you need — or underspending if they are.
What a Bonnell spring does well
- Firm, even support: the connected coil holds the whole surface evenly — a flat, supportive feel that suits back and stomach sleepers and heavier loads.
- Excellent airflow: the open coil structure is the most breathable build we stock — heat and humidity move through it rather than building up, which counts in this climate.
- Simple and durable: a proven design with little to go wrong, which is part of why it's the most affordable mattress we carry.
- Brand-new with a warranty: the low price is the construction, not a catch — every Bonnell is a new mattress covered by a manufacturer's warranty.
Bonnell spring and Queensland heat
One genuine, no-asterisk advantage: of everything we stock, a Bonnell spring breathes best. There's no dense foam slab to trap heat — just an open coil structure air moves straight through. On a sticky South-East Queensland night that's a real, felt benefit, and it's a big part of why a simple innerspring still earns its place in this climate even against pricier constructions.
Firmness
Bonnell springs naturally sit in the medium-to-firm band — even, supportive, and not designed to deeply contour. Sleeping position is the best guide: back and stomach sleepers and heavier builds usually do well on firm; dedicated side sleepers wanting pressure relief may prefer a softer or contouring construction.
- MediumThe softer end of the Bonnell range — even support with a little give. See medium firm.
- FirmThe classic Bonnell feel — flat, even, supportive. Suits back and stomach sleepers and heavier builds. See our firm range.
- Extra firmMaximum, even support with minimal give. See extra firm.
- Softer feel?For plush or contouring comfort, a Bonnell isn't the right base — see soft & plush or memory foam.

Bonnell Spring Mattress FAQs
What is a Bonnell spring mattress?
The traditional innerspring design — hourglass-shaped coils connected together so the mattress supports as one unit. It gives firm, even support and excellent airflow, and it's the most affordable construction we stock.
What's the difference between Bonnell and pocket spring?
Bonnell coils are linked and move together; pocket spring coils are individually wrapped and move independently. Bonnell is firmer, simpler and cheaper; pocket spring contours more and transfers less movement between sleepers. Bonnell for value and firm support; pocket spring if partner disturbance matters.
Is a Bonnell spring mattress good for couples?
It can work, but it's the honest weak point: because the coils are connected, movement carries across the bed more than on a pocket spring. For occasional or guest use it's rarely an issue; for two people sharing nightly, a pocket spring is the better long-term choice.
Why is it so much cheaper than other mattresses?
The price is the construction, not a catch. A connected-coil design is simpler to build than individually-wrapped springs or thick foam comfort layers, so it costs less to make. Every Bonnell is a brand-new mattress with a manufacturer's warranty.
How much does a Bonnell spring mattress cost at A2Z?
From around $99 for a single — the lowest entry point of any mattress type we carry — rising with size. The product grid above shows current pricing. Interest-free payment is available through Afterpay, Zip, Latitude, Klarna and PayPal.
