| Click-clack / futon | Fair | Fair | Very good | Small | Possible |
| Daybed with trundle | Good | Limited | Good | Medium | Yes |

| Chair bed | Limited | Good | Good | Small | Occasional |
| Wall bed with sofa | Very good | Fair | Good | Medium | Yes |
"Floor space when open" is the footprint of the bed, plus the space you need to walk around it. "Daily use" means the type can reasonably be slept on every night if you choose a good mattress for it.
Pull-out sofa bed
The classic sleeper. You remove the seat cushions and unfold a metal frame stored inside the sofa base. The mattress is thin and folds with the frame, usually in three sections.
- Good: looks and sits like an ordinary sofa; the bed is hidden completely; full and queen sizes are common.
- Watch for: a bar or gap felt through thin mattresses, heavy frames, and the cushions you need to store somewhere while the bed is out.
Click-clack and futon
The backrest folds flat to meet the seat, creating a sleeping surface from the sofa's own upholstery or a separate futon mattress. A click-clack locks at upright, reclined and flat positions.
- Good: opens in seconds, needs little extra floor space, light enough to move.
- Watch for: a seam where back meets seat, firmer and shallower seats, and widths that suit one adult better than two.
Daybed with trundle
A single-width bed with a back and arms, used as a sofa by day. Many have a second mattress on a trundle underneath that pulls out, and some trundles pop up to the same height to make a larger bed.
- Good: takes a standard single mattress, so sleep comfort can be as good as a normal bed; easy for children and teenagers.
- Watch for: deep seat that needs cushions to sit comfortably; the pop-up trundle leaves a join down the middle.
Sleeper sectional
An L-shaped or modular sofa where one section pulls out or lifts to form a bed, often with storage under the chaise. The mechanism is usually pull-forward rather than fold-out.
- Good: generous seating, storage, and a bed that's quick to make up.
- Watch for: large delivery pieces, sleeping surfaces made of seat cushions, and handed layouts (left or right chaise) that can't be swapped later.
Chair bed
An armchair that unfolds into a single bed, either with a pull-out frame or fold-out cushions. Useful in a study or a corner where a full sofa won't fit.
- Good: small footprint closed, a spare bed in a room that has no space for one.
- Watch for: narrow sleeping width, often around 60 to 80 cm (24 to 32 in), and short length on some designs.
Wall bed with sofa
A fold-down wall bed (often called a Murphy bed) with a sofa built in front of it. The bed swings down over the sofa, which stays in place underneath. The bed uses a normal mattress.
- Good: the best sleep of any convertible type, since the mattress is full thickness; the bed can be left made up.
- Watch for: it must be fixed to a sound wall, needs enough ceiling height, and usually costs more to buy and install. Check the wall construction and fixing instructions before ordering.
Picking a type
If someone will sleep on it most nights, start with a daybed or a wall bed. If it's mainly a sofa with occasional guests, a pull-out or sleeper sectional gives the best seat. If space and speed matter most, a click-clack is hard to beat. The daily or guest guide goes into the trade-offs.
