Best Memory Foam Sofa Bed for Daily Use: The Koala Sofa Bed

Most sofa beds let you down the moment you actually sleep on them — a thin mattress, a metal bar in your back, a mechanism that takes two people to operate. If you're after a memory foam sofa bed you can genuinely sleep on night after night, the goal is simple: a real sleep surface, without the bar feel.

How to Choose a Sofa Bed for Everyday Use

If you'll be sleeping on it regularly — not just twice a year — three things matter more than anything else.

• Get the mattress right. A sofa bed you sleep on nightly needs a proper sleep surface, not a thin pad over a metal frame. Look for a full-size mattress and a supportive foam layer (the Koala Sofa Bed uses a Kloudcell™ topper). If you can feel a bar through the middle when you lie down, it isn't built for daily use.
• Measure your space twice. Check both the sofa footprint and the bed footprint when open. The Koala Sofa Bed (King) is 177 cm wide as a sofa and opens to 222.5 cm deep, so leave clearance in front. In a studio flat or box room, the Single (1.5-Seater) at 121.9 cm wide is the easiest fit.
• Match the size to who sleeps on it. A Single suits one adult or a small space; a Double works for most guest rooms; the King gives two people a full night's sleep without disturbing each other. Add the Ottoman if you also need hidden storage or a side table.

Memory Foam Sofa Bed Features

A memory foam sofa bed earns its place by doing both jobs well: comfortable enough to sit on every day, supportive enough to sleep on properly. Here's what sets the Koala Sofa Bed apart from a standard pull-out.

• FlipBed™ conversion. The seat flips out into a flat sleep surface in seconds. No bar to pull, no frame to unfold, no latch to fight. Sit-to-sleep in one motion. If you're converting it every night, this is the feature that makes it livable.
• Kloudcell™ sleep surface. The seat is a full-size mattress topped with Koala's Kloudcell™ foam, not a lumpy fold-out pad. It stays flat and seamless where the frame folds, so you get real mattress comfort — cool, supportive and pressure-relieving — every night.
• Deep, supportive seats. Deep seats — 11% deeper than the 3rd Gen — with a perfectly angled backrest and lumbar support.
• Machine-washable, water-resistant Life-proof fabrics. Zip-off covers go straight in the washing machine (cold, max 30°C). A sofa bed used nightly needs to be cleaned like one.
• Tool-free assembly. Parts slot, screw and zip into place with alignment guides and coloured tabs — no Allen keys or screwdrivers required. The sofa bed ships in 5 boxes manageable by one person; the ottoman in 2.
• FSC® certified timber frame. Responsibly sourced poplar plywood, built for daily use.
• Flexible payments. Spread the cost over three payments at checkout.

The Koala Sofa Bed Ottoman

The Ottoman is designed as the perfect sidekick to the Koala Sofa Bed — a flexible standalone piece that adds function without clutter.

• Hidden storage. Lift the lid for concealed storage that keeps your space looking sharp and your mess out of sight.
• Flip-top side table. Flip the top over to reveal a hard surface, and the ottoman moonlights as a stable little side table (recommended maximum weight 5 kg).
• Extra lounging space. Use it right alongside your sofa bed for legs-out, stretch-out lounging.
• Matching Life-proof fabrics. It comes in the same Koala-exclusive fabrics as the sofa bed, with removable, washable covers. (Note: the Sandstone and Coastal Moss cord fabrics are not water-resistant — see care instructions.)

Available in These Colours

Koala designs its fabrics in-house — Koala-exclusive colours crafted in the Sydney studio and not available elsewhere. Both the sofa bed and the ottoman share the same range across three fabric tiers:

• Classic: Olive Butter, Morning Fog, Cinnamon Sky

• Cord: Sandstone, Coastal Moss

• Luxe: Silver Sand, Forest Dawn, Moonlit Silver

All Life-proof fabrics are washable, and most are water-resistant (Sandstone and Coastal Moss cord excepted). The washable covers let you refresh the room look without replacing the sofa.

What Is a Memory Foam Sofa Bed?

A memory foam sofa bed is a sofa that converts into a sleeping surface using a foam comfort layer — no coil springs, no metal bar running through the mattress. The best ones feel like two things: a sofa worth sitting on all day and a bed worth sleeping on all night.

Most sofa beds fail the second test. Standard pull-out designs stretch thin mattresses over metal fold-out frames. After regular use, you feel the cross-bar — the structural bar through the centre of the frame. That's the reason sofa beds have a reputation for bad sleep, and why "no bar feel" is still a genuine differentiator.

The Koala Sofa Bed removes the problem entirely. The FlipBed™ seat flips rather than folds out, supported by a slatted base, and the Kloudcell™ topper sits on top of a full-size mattress — flat and uninterrupted across the whole sleep surface. No bar. No seam. No gap. It's engineered for a genuine full night's sleep rather than the occasional overnight guest — and it shows in the reviews: 4.9/5 from 1,642 buyers, 99% of whom would recommend it.

This matters most if you're using the sofa bed regularly — a studio flat, a home office that doubles as a spare room, or any space where the sofa needs to work hard daily. In those rooms, the Ottoman adds hidden storage and a flip-top side table without taking up extra footprint.

Designed to Last — and to Do Good

Koala is a certified B Corporation and a 1% for the Planet member, and the Koala Sofa Bed is a Good Design Award winner. The frame is built from FSC® certified poplar plywood, and the Life-proof covers now use more recycled content than before, with PFAS-tested treatments. It's furniture engineered to be sat on, slept on, and kept — not replaced. You can read more about the materials and testing on the Innovation page and about the brand on Our Story.

Frequently Asked Questions

Is a memory foam sofa bed comfortable enough to sleep on every night?

Yes — provided it has a proper mattress rather than a thin pad over a metal frame. The Koala Sofa Bed pairs a full-size mattress with an integrated Kloudcell™ memory foam topper and a slatted base, so there's no bar and no gap. It's designed for nightly use, not just occasional guests.

What size is the Koala Sofa Bed when it's open as a bed?

The King (3-Seater) opens to a 155 × 209 cm sleep surface and 222.5 cm total depth; as a sofa it's 177 cm wide. The Double and Single are narrower — 162.5 cm and 121.9 cm wide respectively — making the Single a good fit for a studio flat or small box room. Always measure both the sofa and open-bed footprint before buying.

What is Kloudcell™?

Kloudcell™ is Koala's proprietary open-cell foam, taken from Australia's most awarded mattress range. It delivers pressure-relieving support and breathability with the contouring feel of memory foam but less heat retention — so the sofa bed sleeps cool and supportive rather than hot and sinking.
