For guests who stay more than once or twice a year, a sofa bed beats an air mattress: there is nothing to inflate or store between visits, and it works as a sofa every other day. An air mattress suits rare visits, when you have cupboard space but no room for another sofa.
- If two people often stay over: pick the Elvis 3 Seater Pull-Out Sofa Bed, which its product page lists as sleeping two.
- If the guest bed has to fit a study or a small lounge: pick a compact L-shape like the Oasis Pull Out Sofa Bed, 206 cm long, 160 cm deep as a sofa and 185 cm with the bed out.
- If you have nowhere to keep spare bedding: pick the Samson 3 Seater Fabric Sofa Bed with Reversible Chaise, whose chaise top lifts to reveal a storage compartment.

Sofa bed vs air mattress, side by side
Both give a guest somewhere to sleep, but they solve different problems. A sofa bed is furniture first: it earns its floor space as seating every day and turns into a bed when someone stays. An air mattress is a temporary bed that lives in a cupboard until you inflate it.
| Feature | Sofa bed | Air mattress |
|---|---|---|
| How it sleeps | A flat surface that keeps the same feel all night | Bouncier; firmness depends on the pump and can drop overnight |
| Getting it ready | Move the coffee table, pull the bed out, add bedding | Clear a bed-sized patch of floor, inflate it, add bedding |
| Between visits | The bed goes back in; on many models the bedding fits in the chaise | Deflate, fold and store the mattress, the pump and the bedding |
| Floor space | A permanent footprint, but it is also your sofa | None when packed away; a bed-sized patch when in use |
| Cost to buy | More up front, though it doubles as seating you would need anyway | Less up front |
| Suits | Regular guests, and rooms that double as a study or second lounge | Rare guests, overflow nights and trips away |
Usually the last row decides it. If guests are part of normal life, a sofa bed works for you every day, not just on the nights someone stays over.

Sofa bed or air mattress: how often do guests stay?
How often people stay is the simplest test. A sofa bed is worth it if:
- family or friends stay several times a year, or one person stays often;
- the spare room is really a study, media room or second lounge that needs seating anyway;
- you want the guest bed ready without a pump or a power point;
- you would rather guests slept off the floor.
An air mattress is enough if:
- guests stay once a year or less;
- you need a bed that travels, for camping or a stay at someone else's place;
- you have cupboard space but no room for another sofa;
- you need one extra bed for a busy weekend when every other bed is full.
Plenty of homes keep both: a sofa bed for regular visitors and an air mattress in the cupboard for the night everyone arrives at once.
Are blow-up mattresses as comfortable as a sofa bed?
An air mattress can be perfectly fine for a night or two. The differences show up over a longer stay:
- Firmness that changes. An air mattress is only as firm as it was pumped, and air cools and contracts overnight, so it can feel softer by morning and may need topping up.
- Movement. Air shifts when you do, so when two people share, each roll travels across the bed.
- Height. A standard air mattress sits on the floor. A pull-out sofa bed brings the bed up: on the Elvis the seat base lifts level with the lounge, and on the Samson the hidden section lifts up to seat level, so getting in and out is like sitting down on the sofa.
A sofa bed is still a guest bed, not an everyday mattress. Every sofa bed in this guide is described on its product page as a bed for guests. If someone will sleep on it every night, look at a bed frame and mattress instead.
Fabric is worth a thought too, because a sofa bed gets sat on every day as well as slept on. The Elvis is upholstered in heavy-duty Rhino fabric, which our Rhino fabric guide explains.
Setting up and packing away
With a pull-out sofa bed, getting a guest bed ready is a short job: move the coffee table, pull the bed section out and make it up with sheets, pillows and a quilt. When your guests leave, the bed goes back in and the room is a lounge again.
An air mattress takes more steps each time. You find the pump (and a power point, if it is electric), clear a bed-sized patch of floor, inflate it and make it up, and you may need to top it up on the second night. Afterwards you deflate it, fold it and find somewhere to keep the mattress, the pump and the bedding.
That last step is where a sofa bed with storage wins outright, because the bedding can live inside the sofa. The Elvis has a hidden compartment in its chaise, and on the Samson and the Oasis you lift the chaise top to reach a storage compartment. Our guide to corner sofa beds and pull-out couches compares where the storage sits on each model.
Which suits a small home?
In many homes the guest room is really a study, a media room or the main lounge. That is where a sofa bed earns its floor space: the room stays useful all year instead of holding a bed that sits empty most weeks. An air mattress needs no permanent space, but it still needs a cupboard big enough for it and the pump.
The catch with a sofa bed is the extra depth when it is open. The Oasis page gives both figures: 160 cm deep as a sofa and 185 cm with the bed extended, on a 206 cm length. The Samson is 212 cm long and 134 cm deep with its chaise, and the Elvis is 235 cm wide and 160 cm deep with its chaise. Measure the wall, the depth with the bed out and a way past it before you buy.
All three are three-seaters with a chaise, and the Samson and Oasis chaises switch sides any time, which helps if you rent and may move. Compare more in our 3 seater sofa beds, or browse every sofa bed and pull-out couch in the range.
Sofa bed vs air mattress FAQs
Is a sleeper sofa the same as a sofa bed?
Yes, they are two names for the same thing: a sofa with a bed built in. Sleeper sofa is the more common term in the US; in Australia you will usually see sofa bed or pull-out couch.
What is an air sofa bed?
It is an inflatable that works as a seat and opens out into an air mattress. It saves space the way an air mattress does, but it is still an inflatable, with the same pump, the same top-ups and the same risk of a slow leak.
Can you get a sofa bed with an air mattress?
Some sleeper sofas use an inflatable mattress on a fold-out frame. The sofa beds in this guide do not: the bed is the sofa's own pull-out section, so there is nothing to pump up. If you have more guests than beds, an air mattress on the floor beside the sofa bed makes a handy overflow bed.
Is a Z bed or an air bed more comfortable?
They feel different. A Z bed is a folding frame with a foam mattress, so its firmness stays the same all night, while an air bed's firmness depends on how hard it is pumped and can drop overnight. Both need storage space between visits, which is the problem a sofa bed solves.
How many people can sleep on a sofa bed?
It depends on the model, so check the product page. The Elvis page lists it as sleeping two. If a page does not say, ask in a showroom and lie on the open bed yourself.
Where can I try a sofa bed before buying?
We have five showrooms: Rocklea, Virginia, North Ipswich, Bundall and Beenleigh. Ask which store has the sofa bed you want on display, then open the bed, sit on the seat and check the size against your room.
