Armless vs Armchair-Style Sofa Bed

Armless sofa beds save width and suit tight spaces because they skip the arm rests entirely, putting every centimetre into the seat and sleep surface. Armchair-style sofa beds have firm arm rests that give a traditional sofa look, better lateral support when sitting, and a natural pillow rest in bed mode, at the cost of 30 to 50 cm of extra width. Below we cover the definition of each, a side-by-side comparison, and which suits small spaces vs everyday seating comfort best.

Key Takeaways

• Armless sofa beds skip the arm rests entirely, saving 30 to 50 cm of overall width compared with an armchair-style equivalent

• Armchair-style sofa beds have firm arm rests that give a traditional sofa look, better lateral seating support, and a natural pillow rest in bed mode

• Armless suits small spaces: studios, home offices, tight living rooms where every centimetre counts

• Armchair-style suits everyday seating comfort: better lateral support, sofa-like feel, and pillow rest for reading or watching TV

• Does Koala offer an armless sofa bed, an armchair-style sofa bed, or both? We break it down further below, along with the exact dimensions and widths that suit compact rooms vs everyday-use living rooms

What Is an Armless Sofa Bed?

An armless sofa bed is a sofa bed designed without arm rests, so the seat width extends fully to the sides of the frame. Skipping the arms saves 30 to 50 cm of overall width compared with an armchair-style equivalent, gives more usable sleep surface, and creates a modern, minimalist look that suits contemporary and Scandinavian interiors.

Key features of an armless sofa bed:

• No arm rests: the seat extends fully across the frame width without structural arms on either side

• Compact footprint: 30 to 50 cm narrower than an armchair-style equivalent

• More usable sleep surface: the extra width becomes bed width when the sofa bed is open

• Modern aesthetic: minimalist, contemporary, Scandinavian-friendly styling

• Trade-off: no lateral seat support when sitting, no built-in pillow rest in bed mode

Armless designs became popular with Scandinavian and Japanese-influenced modern furniture. They're common in studio flats, home offices doubling as guest rooms, and any space where floor efficiency matters more than traditional sofa aesthetics.

What Is an Armchair-Style Sofa Bed?

An armchair-style sofa bed has firm arm rests on both sides that give it a traditional sofa look, provide lateral support when sitting, and create a natural pillow rest when in bed mode. Arm rests typically add 15 to 25 cm of width per side to the overall footprint compared with an armless equivalent.

Key features of an armchair-style sofa bed:

• Firm arm rests on both sides, integrated into the frame

• Traditional silhouette: classic sofa look, works with most interior styles

• Lateral support: rest your arm, prop your feet, support side-sleeper pillows

• Pillow rest in bed mode: arms hold pillows in place near the head of the bed

• Trade-off: larger overall footprint compared with armless designs

Armless vs Armchair-Style Sofa Bed at a Glance

Armless and armchair-style sofa beds trade off differently across seven factors. Here's the side-by-side.

The takeaway: armless wins on floor efficiency and modern styling; armchair-style wins on daily seating comfort and traditional sofa function. Neither is universally better; the fit depends on your room and how you'll use the piece.

Does Koala Offer an Armless Sofa Bed, an Armchair-Style Sofa Bed, or Both?

Our sofa beds are armchair-style, with arms on both sides; we don't currently offer an armless design. The Koala Sofa Bed is built with firm armrests so it looks and sits like a proper sofa during the day, then converts to a full-size bed at night. If you were leaning towards armless to save width, our 1.5-Seater (117 cm wide) gives you the smallest footprint in the range while keeping the arms. If you only need extra seating rather than a bed, our armchairs range is the better fit.

Our armchair-style Koala Sofa Bed specs:

• Arm height: 58 cm across all variants

• Seat depth: 60 cm (11% deeper than the 3rd Gen's 54 cm seat) with angled backrest and lumbar support

• Depth (sofa mode): 104.5 cm across all variants

• Depth (opened, bed mode): 225.5 cm

• Widths: 1.5-Seater 117 cm, 2.5-Seater 152 cm, 3-Seater 177 cm

• Mechanism: FlipBed™ (one-motion, no tools required)

• Mattress: full-size mattress with Kloudcell® topper

• Backing: 120-day trial and 5-year warranty on frame and mechanism

If you're weighing armless-vs-armchair for a compact room, the 1.5-Seater Koala Sofa Bed is worth comparing against armless options because it delivers armchair-style comfort in a footprint closer to a 2-seater armless design. For larger rooms where seating comfort matters more than every centimetre of width, the 2.5-Seater or 3-Seater gives you the full sofa experience with FlipBed™ sleep quality.

Which Suits Small Spaces Best

Armless sofa beds suit small spaces best because they save 30 to 50 cm of overall width compared with an armchair-style equivalent, and every centimetre goes into seating or sleeping rather than structural arm rests. For studios, one-bed flats, home offices doubling as guest rooms, or any room where the sofa bed sits tightly against a wall, armless is usually the better fit.

Armless suits these small-space scenarios:

• Studios where the sofa bed is primary seating and primary bedding, and every centimetre of width matters

• Home offices doubling as guest rooms with a tight desk-and-sofa layout where arms would compete for space

• Tight living rooms where 30 to 50 cm of extra width improves the room's flow

• Rooms where the sofa bed sits against a wall or between two walls, so arms would waste space

• Buyers who prioritise sleep-surface width for the total room footprint

Armless isn't ideal for:

• Family living rooms where lateral seating support matters for daily use

• Regular sofa-and-lounge rooms where the traditional armchair look works better with existing furniture

• Anyone who values arm rests for reading, watching TV, or propping pillows

For genuinely tight spaces where a full-sized sofa bed doesn't fit at all, our armchair-style Koala Sofa Bed 1.5-Seater (117 cm wide) is a compact option that keeps the sofa comfort while fitting narrow footprints. Alternatively, our armchairs range offers seating options for spaces where a full sofa bed isn't practical.

Which Suits Everyday Seating Comfort Best

Armchair-style sofa beds suit everyday seating comfort best because the arm rests provide lateral support when sitting, a natural rest for the arm when reading or watching TV, and a place to prop pillows or cushions during daily use. Armless sofa beds are fine for occasional sitting but feel less like a proper sofa for regular lounging.

Armchair-style suits these seating scenarios:

• Regular sofa-and-lounge use where you'll actually sit on the sofa daily

• Reading or watching TV where arm rests support the arms and hold pillows in place

• Family living rooms where guests expect a traditional sofa look and feel

• Side sleepers who use the arm as a natural pillow rest when the sofa is in bed mode

• Buyers prioritising sofa-quality seating over floor-footprint savings

Comfort considerations when comparing armchair-style options:

• Arm height: 55 to 60 cm is standard AU sofa bed arm height; our Koala Sofa Bed sits at 58 cm

• Seat depth: 55 to 65 cm suits most adults; our Koala Sofa Bed has a deep 60 cm seat (11% deeper than the 3rd Gen) with angled backrest and lumbar support

• Backrest angle: slight recline (not vertical) supports natural sitting posture

• Cushion firmness: medium-firm supports both seating and short naps without collapsing

For a sofa bed you'll use as a sofa daily and a bed occasionally, armchair-style is almost always the better choice. Our Koala Sofa Bed is engineered around exactly this use case: proper sofa comfort with real-mattress sleep quality via the FlipBed™ mechanism.
