Choosing a sofa bed can quickly become a headache, given the wide variety of models, sizes, and mechanisms available. Among the most popular options, the 120cm sofa bed stands out as an ideal compromise between space saving, comfort, and versatility. Neither too narrow nor too bulky, it's particularly well-suited to small spaces while offering a very comfortable bed for one person—or even two occasionally.
Discover in this comprehensive article why a 120cm bed is an excellent choice , what its advantages are, how to select it well and our recommendations for high-performance models.
1. A perfect size for small spaces
The 120 cm bed represents an excellent compromise for those who want to optimize their room while maintaining real sleeping comfort.
✔️ Ideal for studios and small living rooms
Its width, less than that of a 140 cm, allows it to be easily integrated into a studio, a small bedroom or a multifunctional living room.
✔️ Controlled bulk
In sofa mode, 120 cm convertible sofas often have a width between 150 and 180 cm, which facilitates movement in the room.
✔️ An aesthetically pleasing space-saving solution
Many models are available with or without armrests, allowing the sofa to be adapted to the layout of the accommodation.
2. A very good level of comfort for one person
A 120 × 190 cm bed offers 30 cm more width than a standard single bed (90 cm), which significantly changes the experience.
✔️ Wider than a single bed
The user can move freely without feeling cramped.
✔️ Occasional sleeping space for two people
Although designed for one person, a 120cm convertible sofa can occasionally accommodate two people.
✔️ Optimal comfort for everyday use
With a mattress that is 12 to 16 cm thick and has good density, it is a perfect solution for everyday sleeping.
3. An economical and sustainable choice
The 120cm convertible sofa is often more affordable than the 140 or 160cm models, while still maintaining excellent comfort.
✔️ A controlled budget
Smaller width = less material = more attractive price.
✔️ Fast and robust mechanisms
Most models are available with a rapid/express mechanism , slatted or metal grid bed base, guaranteeing very good durability.
