Living in a small space doesn't mean sacrificing comfort or functionality. On the contrary, it encourages you to be more resourceful in your furniture choices! A sofa bed is an ideal solution for optimizing space in a small apartment or room, offering both comfortable seating and an extra bed. But with so many models to choose from, how do you make the right choice? Follow our guide to find the perfect sofa bed for your home.
Measure the space available for your sofa bed
This is the most crucial step. Before you even think about style, get out your tape measure!
The sofa space in the sitting position
Measure the width, depth, and height available for the sofa. Don't forget the space needed for circulation around the sofa.
The sofa space in bed position
This is often a major oversight. Determine the total footprint of the sofa once unfolded. Make sure there will be enough room to open the bed without getting in the way or blocking a door or window. Also consider space for a bedside table or rug.
Access
Measure the width of your doors, hallways, and staircases. This will save you the unpleasant surprise of not being able to fit your new sofa!

Identify the main use of the sofa bed: extra bed or daily bed?
The frequency of use of the bed function is decisive for the type of mechanism and the quality of the mattress.
Occasional use (extra bed)
If the bed is only used a few times a year for guests, a thin mattress and a simple mechanism ( click-clack , BZ ) may be sufficient. The emphasis will be on design and comfort when sitting.
Regular or daily use
If the sofa bed is intended to serve as a main bed (in a studio apartment, for example), the quality of the mattress is essential. Choose a thick mattress (minimum 12-14cm), made of high-resilience foam. Choose a quick and easy opening mechanism , such as the rapido or express system, which does not require removing the cushions.
Types of convertible sofa mechanisms: which one is right for my small space?
Each mechanism has its advantages and disadvantages in terms of size and comfort.
The click-clack
Very popular for small spaces. The backrest tilts backward to form a bed. Simple, quick, and generally economical. The disadvantage is that the sofa is often against a wall, which can scratch the wall from repeated handling. The seat and backrest form the mattress, which can affect comfort.
The BZ
Similar to the sofa bed but unfolds in a "Z" shape. It's compact and unfolds perpendicular to the wall, which can be an advantage depending on the layout of your room. Like the sofa bed, the seat and backrest form the sleeping area.
The rapido (or express) system
Ideal for frequent use. The bed unfolds with the pull of a handle, without having to remove the cushions. The mattress is separate from the seat cushions, which offers greater sleeping comfort. Generally more expensive and slightly bulkier than sofa beds/beds, but the comfort is unmatched for regular use.

The convertible sofa with pull-out drawer
Less common but useful for extra sleeping space. A drawer extends under the seat, providing a low sleeping area. Ideal for children or short-term guests.
The comfort of the convertible sofa: don’t neglect it!
A sofa, even a convertible one, must above all be comfortable in the sitting position.
- Seat: Choose high-resilience foam for long-lasting durability. Test the seat depth: your feet should touch the floor.
- The backrest: A comfortable, well-padded backrest is essential to support your back.
- The mattress (for the bed function): as mentioned previously, the more frequent the use, the higher the quality and thickness of the mattress must be. At Convertible Center, you have the possibility to choose your mattress when you buy your convertible sofa .
The style and materials of the convertible sofa: harmonious integration
Even in a small space, aesthetics matter!
- Light colors: they visually enlarge the space and bring brightness.
- Slim legs: visible, slim legs lighten the silhouette of the sofa.
- Compact armrests: Avoid armrests that are too wide, as they take up valuable space. Some models have very thin armrests or no armrests at all.
- Material: Fabric is generally warmer and softer than leather. For a small space, a durable, easy-care fabric is a plus.
- Built-in storage: some convertible sofas have storage spaces for pillows, among other things.
By following these tips, you will be able to choose the sofa bed that not only fits perfectly into your small apartment or small room, but will also meet all your needs in terms of comfort and functionality.
