TL;DR
Most sofa beds aren't comfortable, and it comes down to two things: mattress thickness and what's supporting it. Quality sofa beds solve both problems. Eva's Slideaway Sofa Bed uses a timber slat base and multilayer foam designed to be slept on every night, not just occasionally.
If you've ever woken up with a metal bar pressed into your spine, you already know what most sofa beds feel like. That reputation is earned.
But the question isn't whether sofa beds can be bad. It's whether they have to be. A cheap pull-out with a 7cm foam mattress is a different product category from a well-built Slideaway Sofa Bed with a proper support base. Both are called sofa beds. They don't sleep the same.
This post covers why sofa beds get uncomfortable, what the good ones do differently, and whether any of them are worth sleeping on regularly.
Why most sofa beds are uncomfortable
Most sofa beds were designed to look like furniture, not to sleep like a mattress. The result is a product that does both jobs badly.
The mattress is too thin
Most pull-out sofa bed mattresses sit between 7 and 10 centimetres thick. A proper adult mattress is at least 15cm. At 7-10cm, you're sleeping on a compressed slab of foam that loses its shape fast and offers almost no pressure relief.
This is the root problem. You can improve the frame, the mechanism, and the fabric. If the mattress is 8cm of low-density foam, no one sleeps comfortably.
The metal bar in the middle
Pull-out sofa beds fold in half. When you open them, the mattress unfolds too, and the fold sits somewhere under the sleeping surface. On cheaper models, that ridge presses directly into your back. It's not subtle. Most sleepers feel it within an hour, and it doesn't improve through the night.
Some mechanisms tuck the fold further away from the sleeping zone. Many don't. Product pages rarely mention it.
The support base collapses
Under the mattress, there's either a metal spring platform or a mesh base. On budget models, both sag. Springs lose tension. Mesh stretches. What started as a flat sleeping surface becomes a hammock within 12 months.
A sagging base means the mattress can't stay flat. Which means your spine can't stay aligned. Which means you wake up sore regardless of how good the mattress started out.
Low-density foam that doesn't recover
Budget sofa bed foam compresses under weight and doesn't spring back fully. Over time, body impressions form. Unlike a regular mattress, which is off-loaded and aired regularly, a sofa bed takes full body weight and spends most of its life folded. Low-density foam fails faster in that cycle.
Thin foam plus a collapsing base is why most sofa beds feel fine the first night and noticeably worse six months later.
What makes a sofa bed actually comfortable
A good sofa bed solves the mattress problem and the support problem, then makes sure the mechanism doesn't add a third.
Mattress thickness
Aim for at least 12cm. Prefer 15cm or more. This gives you enough depth for real pressure relief without bottoming out through the night.
The support system underneath
Eva uses a timber slat base rather than the metal mesh or spring platforms found on most sofa beds. The difference is real: timber slats distribute weight evenly across the sleeping surface and don't sag with regular use. Metal mesh stretches. Springs lose tension. Slats hold their shape.
For a sofa bed you plan to use more than occasionally, the support base arguably matters more than the mattress. A good mattress on a sagging base is still a bad night's sleep.
Foam quality
Higher-density foam holds its shape under pressure, returns to form when you get up, and resists permanent impressions over time. Eva's seat cushions are built from multilayer polyurethane foam with a recycled memory foam and polyester fibre duvet wrap. That wrap adds softness on top of the structural foam layer, which is where many cheaper products cut corners.
Mechanism and sleep surface flatness
Eva's Slideaway Sofa Bed is a pull-out sofa bed where the mattress deploys flat rather than folding in half. End to end, no fold, no ridge. Traditional fold-in-half pull-outs leave a crease in the middle of the sleeping surface. A flat-deploy pull-out doesn't.
For side sleepers or anyone with lower back sensitivity, this matters more than almost any other single factor. A fold creates a pressure point in the middle of the mattress. A flat surface doesn't.
Frame construction
The frame underneath determines how well the slat or spring base holds up over years. A frame that loosens or shifts lets the sleeping surface become uneven. Eva's frame is built from solid American Ash timber and plywood with American Ash veneer, finished with a natural low VOC oil. That gives the support system something stable to sit on long-term.
Can you use a sofa bed every night?
Depends on the sofa bed.
A cheap pull-out with a 7cm foam mattress and a sagging mesh base? No. It'll work for the occasional guest, but daily use will leave you uncomfortable within weeks.
A quality model with a proper mattress, a stable support system, and a flat sleeping surface? Yes. Many people use them this way, particularly in studio apartments or rooms that serve two purposes.
A few things to note if you're planning regular use: side sleepers feel the difference between a thin and thick mattress more acutely than back sleepers. If you have lower back sensitivity, the flatness of the sleeping surface matters more than anything else.
One practical upgrade for regular users is a mattress topper. A 5-7cm memory foam or latex topper adds meaningful cushioning and helps distribute pressure more evenly. It also protects the mattress from body impressions over time. If you're sleeping on a sofa bed most nights, it's worth considering.
How Eva's sofa bed compares
Eva's Slideaway Sofa Bed is a pull-out sofa bed that draws the mattress out flat rather than folding it in half. Key specs:
- Sofa mode: 188cm wide, 111cm deep, 57cm seat height
- Deployed: extends to 153cm total depth, double bed sleeping surface
- Mechanism: Pull-out with flat-deploy system (no fold ridge)
- Support system: timber slat base
- Frame: solid American Ash timber and plywood with American Ash veneer
- Foam: multilayer polyurethane foam with recycled memory foam and polyester fibre duvet wrap
- Weight capacity: 300kg
- Warranty: 5-year frame and fabric warranty, 2-year on other components
- Price: from $2,550 AUD
Compared to the category average, which typically uses a metal spring or mesh base and a 7-10cm mattress, Eva's timber system and layered foam represent a genuine step up. The flat-deploy mechanism, timber slat base, and multilayer foam are built for regular use, not occasional guests.
FAQs
Are sofa beds comfortable for regular use?
A quality sofa bed, yes. One with a mattress 12cm or thicker, a stable support base, and a flat sleeping surface can handle regular use for most people. A cheap pull-out with a thin foam mattress isn't built for it and will feel that way quickly.
What's the most comfortable sofa bed in Australia?
Comfort is partly subjective, but the factors that matter most are mattress thickness, support system type, and mechanism. Within pull-out designs, the key question is whether the mattress folds in half or deploys flat. Flat-deploy pull-outs like the Eva Slideaway Sofa Bed eliminate the ridge problem at the root. Customer reviews back this up: the Eva Slideaway Sofa Bed won the 2026 ProductReview Award in the sofa bed category, which is based entirely on verified customer ratings.
Why do sofa beds feel uncomfortable to sleep on?
Usually one of three reasons: the mattress is too thin (under 12cm), the support base sags or creates unevenness, or the folding mechanism leaves a ridge through the middle of the sleeping surface. Often it's all three.
Does a mattress topper help with sofa bed comfort?
Yes. A 5-7cm memory foam topper adds meaningful cushioning and helps distribute pressure more evenly. It won't fix a sagging base, but it makes a reasonable sofa bed noticeably better and a good one genuinely comfortable.
How thick should a sofa bed mattress be?
Minimum 12cm for a reasonable night's sleep. Prefer 15cm or more, particularly for regular use or if you're a side sleeper.
Is Eva's sofa bed comfortable?
The Eva Slideaway Sofa Bed has won four awards: the iF Design Award 2026, Good Design Gold 2023, Red Dot Award 2024, and the 2026 ProductReview Award in the sofa bed category. The ProductReview Award is based on real customer ratings, not a judging panel. The timber slat base and flat-deploy mechanism address the two most common sofa bed complaints: a support base that sags over time, and a fold ridge that digs into your back. The multilayer foam and memory foam wrap are the same starting point as a proper mattress, not a thin pad added as an afterthought.
What awards has the Eva Slideaway Sofa Bed won?
Four. The Good Design Gold Award in 2023, the Red Dot Award in 2024, the iF Design Award in 2026, and the 2026 ProductReview Award in the sofa bed category. The first three evaluate functionality and usability alongside aesthetics. The ProductReview Award is based on customer ratings. For a sofa bed, that combination of design recognition and customer validation covers both how it's built and how it actually sleeps.
Is the Eva Slideaway Sofa Bed designed for everyday use or just for guests?
Both. Eva built the Slideaway Sofa Bed to work as a main sofa, a daybed, and a bed you can sleep on every night. The timber slat base doesn't sag with repeated use the way metal mesh platforms do, and the foam construction is designed for daily compression. People in studio apartments could use it as their primary bed. It also works well as a guest bed you open a few nights a year. The mechanism is smooth enough that neither use case feels like a compromise.
