What is a sofa bed and trundle?
A sofa bed and trundle is a multifunctional furniture piece that combines a sofa, a pull‑out bed (sofa bed), and an additional hidden bed (trundle) — offering sleeping space for two or more people while remaining a comfortable lounge during the day. In simple terms: it’s a sofa that unfolds into a bed when needed, and includes a secondary under‑bed (the trundle) that can slide out to provide extra sleeping capacity. The main reason Australians love a sofa bed and trundle is its space‑saving versatility, making it ideal for apartments, guest rooms, rental homes, or families needing flexible sleeping arrangements without dedicating extra bedrooms.
Sofa bed and trundle designs vary widely depending on size, mechanism, upholstery, and overall configuration — giving buyers plenty of choice to match their home’s layout and lifestyle. Here are the most common styles:
Classic Pull‑Out Sofa Bed with Under‑bed Trundle
A standard sofa that converts into a bed (via pull‑out or fold‑down mechanism) plus a lower trundle drawer or frame that houses another mattress — ideal for guests or children.
Compact Sofa Bed with Slide‑Out Trundle (Apartment‑Friendly)
Designed for smaller living areas — a compact sofa bed base with a trundle that slides out smoothly, often with a slightly lower mattress for occasional use. Great for urban flats or studios.
Sectional / Modular Sofa Bed with Integrated Trundle
Larger L‑shaped or modular sofas where one section converts into a sofa bed and another module houses a trundle — offering flexibility in seating arrangements and sleeping configurations.
Upholstered Fabric Sofa Bed & Trundle
Sofa beds and trundles upholstered in fabric, linen or tapestry — blending into living room décor and offering softness and comfort that doubles as lounge furniture.
Leather or Faux‑Leather Sofa Bed with Hidden Trundle
Sleeker, modern-looking option with easy-to-clean surfaces — suitable for shared homes, families with kids/pets, or minimalist interiors.
Mattress‑Quality Sofa Bed & Trundle
Higher-end versions offering full-size mattresses (foam, spring or memory foam) for both the main bed and the trundle — suitable if both sleeping surfaces will be used frequently.
Storage + Trundle Combo Sofa Beds
Some designs combine a pull‑out bed and trundle with built-in storage compartments — ideal for storing bedding, pillows or extra linens in small apartments or guest rooms.
Selecting the right sofa bed and trundle requires thoughtful consideration of space, comfort, frequency of use, and home lifestyle. Here’s a practical checklist when choosing one for your Australian home:
Room dimensions & clearance: When both bed and trundle are pulled out, check you have roughly ~200–220 cm length and ~150–180 cm width, depending on mattress size. Also allow space for walking and bed‑making.
Access & delivery path: Ensure the sofa bed and trundle can fit through doorways, hallways or staircases before delivery — modular or compact designs might be easier if space is tight.
Living flow: In lounge‑dining or open‑plan apartments, ensure bed conversion doesn’t block access to other furniture or walkways.
Occasional guest use: Compact sofa bed & trundle with simpler mechanisms is usually fine.
Regular sleep for guests or family: Prioritise robust frames, mattress‑quality beds and smooth, durable trundle mechanisms.
Frequent rearranging (rentals / shared housing): Lightweight or modular versions with easy‑fold mechanisms and removable upholstery work best.
Mattress type: Look for foam, memory foam, or spring mattress options — thicker, supportive mattresses offer better nightly comfort.
Mattress size: Ensure mattress dimensions (length and width) suit adults if intended for long-term use.
Trundle mattress height: Trundle mattresses are often lower — more suited to occasional sleeping or children/guests; consider if intended for regular use.
Frame construction: Prefer kiln‑dried hardwood frames or reinforced metal for durability. Avoid particle‑board frames for pieces that will double as beds.
Upholstery: In homes with children/pets or frequent hosting — choose stain‑resistant or easy‑clean fabrics or faux‑leather. Removable cushion covers ease maintenance.
Cushion comfort: For daily lounging, high‑density foam or fibre‑wrapped cushions improve seat comfort and long‑term durability.
Pull‑out / fold‑down mechanisms: Should operate smoothly, safely and be easy for one person to handle.
Trundle mechanism: Sliding mechanism or wheels should be easy to access — test for ease of movement and lock‑in stability.
Storage integration (if present): Ensure compartments are accessible and won’t interfere with sleeping functionality or comfort.
Modern apartments / minimalist homes: Sleek designs, neutral upholstery, compact profiling suit best.
Family homes / frequent guests: Larger sectional sofa‑bed & trundle with durable materials and comfortable mattresses.
Rental or multi‑use homes: Modular or convertible designs offering flexibility, storage, and ease of cleaning.
A sofa bed and trundle offers a unique combination of versatility, practicality, and lifestyle functionality — ideal for many different living situations in Australia.
Double Sleeping Space in One Piece: The main bed plus a hidden trundle gives sleeping space for two or more without needing multiple beds.
Space-Saving & Multipurpose: Combines lounge seating and extra beds — perfect for small apartments, studios, or guest rooms.
Cost-Effective Furniture Investment: Instead of buying a sofa and two beds separately, one sofa‑bed‑trundle combo does all.

Convenient for Shared or Rental Homes: Easy to convert, compact, and adaptable — suitable for dynamic living arrangements.
Clutter Reduction (with storage options): Integrated storage helps store bedding, pillows or linens — reducing clutter in small homes.
Studio apartments or small flats where space is limited.
Guest rooms or multipurpose living areas (e.g. home office + guest bed).
Families needing extra sleeping space for kids or visiting family/friends.
Shared housing or rental properties requiring flexible sleeping options.
Short‑stay rentals or holiday homes where flexible sleeping arrangements are needed.

As lifestyles evolve — more people renting, downsizing, buying apartments, or needing multipurpose furniture — certain trends are shaping how Australians pick sofa bed and trundle units in 2025. Here are the key developments:
With growing urbanisation and smaller dwellings, compact sofa bed and trundle units — especially modular versions that can be reconfigured — are increasingly popular. They maximise flexibility without compromising living space.
Manufacturers lean toward soft fabric upholstery (linen, woven blends) or neutral-tone faux‑leather — easier to maintain and better suited to modern minimalist interiors. Neutral palettes (grey, taupe, beige) make sofa beds blend into living spaces even when bed is unused.
Sofa bed and trundle designs now often include storage compartments — for bedding, pillows, or linens — reflecting demands for multifunction furniture in compact homes. This triple-function design (sofa + bed + storage) is trending strongly.
Rather than basic thin cushions, many modern sofa bed & trundle sets now come with memory foam or hybrid mattresses — improving sleep comfort and making these suitable not just for occasional guests, but for regular sleeping.
As awareness of sustainability rises, there is increasing demand for sofa beds made with responsibly sourced frames, eco‑friendly upholstery, and construction designed for longevity rather than throw‑away furniture.
Sofa bed and trundle designs are trending toward sleeker, lower-profile looks — easy to integrate into modern living rooms. Slipcovers or removable upholstery are becoming standard to allow easier cleaning and style refreshes.
As more Australians work from home or use rooms flexibly, sofa beds with trundles are seen as key investment — providing a seating area for work or lounging by day, and sleeping space for overnight guests.
The main reason these trends resonate: today’s Australian homes often juggle multiple functions — living, working, hosting guests — and a sofa bed and trundle offers flexibility, comfort and practicality in one smart package.
A sofa bed and trundle is not just functional — with the right styling, it can become an elegant focal point in your lounge or guest space. Here’s how to integrate it seamlessly into your home:
Choose upholstery in neutral tones — soft greys, taupes, charcoal or muted hues — so the sofa bed blends into your décor whether used as bed or couch. Neutral colours make the piece versatile and timeless.
Add textured throws, cosy cushions, rugs, and soft lighting — this creates a welcoming ambience and ensures the sofa remains inviting even when not used as a bed.
Use lightweight coffee tables, ottomans or side tables that can be moved easily when the trundle is pulled out. Avoid heavy fixed furniture that obstructs space.
A large area rug helps define the lounge-sleep zone — keeping visual boundaries clear, especially in studio apartments or open-plan living spaces.
If your sofa bed doubles as a guest bed in a small apartment, combine it with wall-mounted shelves, slim console tables or corner racks — useful for linen, books or decorative items, while keeping floor space clear.
Use neutral bed linen that coordinates with cushion and cushion‑cover colours — when the trundle is stowed, the sofa looks neat and uncluttered. Store spare pillows/blankets discreetly in nearby storage units or baskets.
Floor lamps, reading lamps or adjustable lighting near the sofa help adapt the space for lounging, reading, or overnight guests — creating a warm, welcoming vibe.
Avoid overcrowding with décor — let the sofa bed stand out. Use minimal decorative pieces (a plant, a bowl, or a small tray) for a modern, airy look that still feels lived-in.
In simple terms: treat your sofa bed and trundle as a design anchor — style around it thoughtfully so it feels intentional, flexible, and comfortable — whether for lounging or sleeping.
