In a studio, a small bedroom, or a living room with limited dimensions, a sofa bed should help save space without making the room difficult to live in. To choose the right one, you must consider its footprint once opened, the width of the sleeping area, the mechanism, and also the comfort of the mattress based on how often it will be used.
Start by measuring the space available once the sofa is open
In a small space, checking the width of the sofa when closed is not enough. A model might seem compact during the day but become too bulky once transformed into a bed.
Therefore, measure the space occupied in both configurations. Specifically, check the depth required when the bed is open, as well as the remaining space for movement.
A door, radiator, TV stand, or coffee tables can quickly interfere with the bed's deployment. In a reduced space, a few centimeters can make all the difference.
To better visualize it, you can mark out the dimensions of the open sofa on the floor with adhesive tape. You will see immediately if the walkways remain clear enough.
Choose the sofa width based on the desired sleeping area
The number of seats does not always provide a precise indication of the sofa's footprint. Two two-seater models can have very different dimensions depending on their armrests and structure.
A 2-seater sofa bed with a 120 cm sleeping area can be attractive when you need to limit the width of the furniture. Some models stay around 160 cm wide while offering a sleeping area independent of the seat cushions.
For sleeping two people more comfortably, a 140 cm sofa bed offers more space. However, you must account for a few extra centimeters for the sofa's structure.
Before choosing, always compare the total width of the furniture and that of the mattress. This allows you to know what portion of the footprint is actually dedicated to the sleeping area.
Prioritize a compact and well-thought-out structure
In small spaces, the design of the sofa counts just as much as its dimensions.
Models with slim armrests allow more width to be dedicated to the seat without enlarging the furniture. Versions without armrests go even further by utilizing almost all of the available width.
If you are looking for a small sofa bed, also observe the depth of the furniture. Two sofas of the same width can have a very different footprint in the room.
A 170 cm wide sofa with a 140 cm sleeping area, for example, will be particularly interesting if its structure remains slim and shallow.
Adapt the mattress to the frequency of use
The right level of comfort depends primarily on how often the sofa is used as a bed.
For occasional use, a foam mattress with a density of about 25 to 30 kg/m³ may be suitable. It is adapted for sporadic use, for example in a guest room.
For regular use, prefer a density around 30 to 35 kg/m³. The support will generally be better suited for repeated use, and the mattress will retain its quality better over time.
In the case of daily sleeping, thickness must also be taken into account. A mattress of approximately 13 to 16 cm can provide a level of comfort more suitable for nightly use.
To obtain optimal comfort, look at the density, mattress thickness, and slatted base type together, rather than relying solely on the appearance of the sofa.
Choose a mechanism adapted to the shape of the room
The opening system directly influences the space needed around the sofa.
A "clic-clac" typically unfolds parallel to the wall. The "BZ" model opens perpendicularly and can be interesting in a narrow room with more depth.
The express opening sofa bed unfolds forward and generally integrates the mattress directly into its structure. It is particularly practical when the sofa is used often as a bed, as it allows for quick transformation.
Before choosing a sofa bed, observe the shape of your room. A long, narrow studio will not have the same constraints as a squarer living room.
Consider the main use of the room
The right sofa bed model also depends on the function of the room.
In a studio, the sofa often serves as both the main seating and the bed. You must therefore find a balance between daytime comfort, ease of opening, and bed quality.
In an office or guest room, the sofa generally remains closed most of the time. In this case, you can prioritize compactness and space saving more.
In a small living room, the challenge is more about maintaining fluid movement around the furniture. A slightly narrower sofa can sometimes make the room much more pleasant to live in.
Visually lighten the sofa in a small space
A compact sofa can also appear more discreet depending on its design.
Slim armrests, a simple backrest, or visible legs generally give an impression of lightness. Conversely, a very massive structure can visually shrink the room.
The sofa without armrests is also an interesting option in a small space. Its cleaner structure allows you to gain a few centimeters in width while giving an impression of openness and lightness in the room.
Light shades like beige, ecru, or light gray can enhance this feeling of space. Stronger colors remain possible, however, if the rest of the decor is understated.
Arrange furniture around the sofa bed
Choosing the sofa is not enough to optimize the room. You must also think about the furniture surrounding it.
Light or nesting coffee tables are particularly practical in front of a convertible sofa, as they can be moved easily when opening the bed.
Wall-mounted or shallow furniture also helps free up floor space. In a small home, it is generally better to limit the number of pieces of furniture and focus on a few truly functional items.
The goal is to keep enough free space to transform the sofa into a bed without having to move the entire room.
Which sleeping size to prioritize?
The choice depends primarily on the number of people who will sleep on the sofa.
A 120 cm sleeping area can suit a single person and helps limit the footprint. It is particularly adapted to compact spaces, ideal for studios or guest rooms.
A 140 cm wide sleeping area offers more comfort for two people while remaining compatible with several compact models.
The right choice consists of finding the best compromise between the sleeping area width and the sofa's footprint.
Anticipate the installation of your sofa bed
A small sofa bed may be perfectly adapted to your living room while being difficult to get into your home.
Before ordering, measure the width of doors, hallways, stairs, or the elevator. Also check if certain parts of the sofa can be dismantled to facilitate its installation.
Finally, remember to check its depth. On a compact sofa bed, a few centimeters gained can really improve movement in a small apartment.
The goal is therefore not necessarily to choose a model as small as possible, but to select the one that best utilizes the available space while offering the desired level of comfort.
FAQ about sofa beds for small spaces
Which sofa for a small space?
For a small space, prioritize a compact sofa bed with slim armrests or no armrests. Above all, check its dimensions once opened in order to maintain fluid movement in the room.
What is the best sofa bed for daily use?
For daily sleeping, choose a sofa bed with a sufficiently thick mattress, around 13 to 16 cm, and a density of about 30 to 35 kg/m³. An express opening system is also more practical for use every night.
What is the difference between a "canapé convertible" and a "canapé-lit"?
The "canapé-lit" (sofa bed) is primarily designed to offer a real sleeping experience, generally with a mattress integrated into the structure. "Canapé convertible" refers to a broader family of models that can transform into a bed, such as straight, corner, or modular sofas. It therefore offers more possibilities in terms of shapes and layouts.
