Sofa Bed for Small Spaces: Which Ones Still Fit When Opened

A sofa bed is two pieces of furniture that share a footprint, and you shop for it as the first one. The spec tab leads with the sofa: width, depth, seat height. Those are the numbers for the 360 days a year it is a sofa.

The number that decides whether it works in a small room is the other one — how deep it is when it is open, measured from the wall it stands against. That is the floor your guest has to walk around at night, and it is usually not in the spec tab at all.

So we went and found it. We read ten sleeper sofas from two brands on 7 October 2026, from each brand’s own product page and dimension drawings.

The smallest sofa in the list needs the most floor once it is open — more than any sleeper here whose opened size is published. That is not a quirk of one model. It follows from which way the bed comes out.

The rule: opened depth plus 24 inches

Our bedroom walkway guide uses 24 in as the minimum to walk past a bed and 36 in as the comfortable figure. A sofa bed is a bed, so the same numbers apply to the strip of floor in front of it.

That gives a one-line test for any sleeper:

Room depth needed = opened depth + 24 in. For a comfortable room, + 36 in.

“Room depth” here is the distance from the wall the sofa stands against to whatever is opposite it — the far wall, a desk, a dresser. Measure it before you look at a single sofa. The coffee table has to go somewhere else for the night; it is not in this arithmetic, and it has to fit somewhere that is.

The ten, opened

Every closed dimension below is the brand’s own. The opened depths come from the dimension drawings in each Coddle product gallery, which show the sofa open with the measurements on it. Burrow publishes no opened dimensions; those rows are marked.

Sleeper	Bed	Closed depth	Opened depth	Room depth needed (+24 in)
Coddle Galaxy Loveseat	Full	37.2 in	75 in	99 in
Coddle Nova	Full	37 in	59.9 in	83.9 in
Coddle Matrix	Full XL	36.6 in	51.5 in bed, frame not given	at least 75.5 in
Coddle Tera	Queen	42.1 in	60 in	84 in
Coddle Galaxy	Queen	42.9 in	60 in	84 in
Coddle Gateway	Queen	42.9 in	60 in	84 in
Coddle Optic	Queen	41.5 in	60 in	84 in
Coddle Switch	Queen	41.3 in	60 in bed, frame not given	at least 84 in
Burrow Shift	Queen	32.5 in	not published	at least 84 in
Burrow Span	Queen	34.5 in	not published	at least 84 in

Two rows say “frame not given”. On the Matrix and the Switch, Coddle’s drawing measures the sleep surface only — 51.5 in and 60 in — and the back of the sofa still sits behind it. The real footprint is that plus however deep the back is. On the Nova, where Coddle drew both, the difference is 5.9 in: a 54 in bed in a 59.9 in footprint.

The Burrow rows use 60 in because Burrow describes both as a “genuine queen-sized” mattress, and a standard queen is 60 inches wide. Its photos show the bed running along the wall. The opened depth can only be more than 60; how much more is not published.

Closed depth predicts nothing

Look down the closed and opened columns together. The Nova and the Galaxy Loveseat are 0.2 in apart closed — 37 and 37.2. Opened, they are 15.1 in apart: 59.9 against 75.

And the queens, which are four to six inches deeper closed, open to 60 in — less than the loveseat by fifteen inches.

The reason is the direction of the bed.

• Along the wall. On a full-size sofa, the bed’s long side runs parallel to the wall. A queen is about 80 inches long and 60 wide, and an 86-inch sofa has room for the 80 inches across its width. What comes out into the room is the 60.
• Out from the wall. A loveseat is too short for that. The Galaxy Loveseat is 66.5 in wide and its full mattress is 75 in long, so the bed has to turn and come straight out at you. What comes into the room is the 75.

That is the trap with a loveseat sleeper in a small room. It is the obvious pick because it is small, and it is small in the one direction that does not matter at night.

In an 8-foot room

Put it on a plan. A spare room or a den 10 ft wide and 8 ft deep — 96 in from the sofa wall to the opposite wall — with the sofa centred on the long wall.

The Galaxy Loveseat, open, leaves 21 in between the foot of the mattress and the wall. That is three inches under the walking minimum: your guest gets in from the side, and nobody walks past the end of the bed.

Swap in a queen — the Tera, 86 in wide and 60 in deep open — and the walkway is 36 in: the comfortable figure, exactly. A wider sofa, a bigger bed, and fifteen inches more floor.

The Nova, a full, is almost the same: 59.9 in open, 36.1 in left. It is a smaller bed in the same footprint as the queens, because its trundle comes out in front of a sofa back that stays where it is.

Closed, the picture is the opposite. The loveseat leaves 58.8 in of floor and the Nova 59 in — the two smallest sofas look interchangeable all day. The difference only appears at night.

In centimetres: the 8-foot room is 243.8 cm. The loveseat opens to 190.5 cm, the queens to 152.4 cm, and the Nova to 152.1 cm. The walking minimum is 61 cm, the comfortable figure 91.4 cm.

What each one costs you, open

Read the table as a list of room sizes rather than sofas.

• Under 7 ft (84 in) of depth: the Matrix is the only candidate. Its bed is 51.5 in, and the question is how much frame sits behind it — in an 84-inch room it can be up to 8.5 in and still leave 24. Coddle does not say. Ask before you order.
• 7 ft to 8 ft (84–96 in): the Nova, Tera, Galaxy, Gateway and Optic reach the 24 in minimum at 84 in and the comfortable 36 in at 96. The Switch, the Shift and the Span need at least as much, plus whatever their frames add behind a 60 in bed.
• 8 ft 3 in (99 in) and up: now the Galaxy Loveseat works. In anything shallower, it is a loveseat that is also a bed you cannot walk around.

Width runs the other way, and that is the honest trade. In a room where the wall is the short dimension, a 66.5 in loveseat fits where an 86 in queen will not. If your room is narrow and deep, the loveseat is the right answer. If it is wide and shallow — most spare rooms and dens — it is the wrong one.

Things the spec tabs disagree about

We read every number twice, once from the spec tab and once from the drawing, and three products did not agree with themselves.

• Galaxy Loveseat: the spec tab says 37.2 in deep and 38 in high; the dimension drawing says 36.6 and 37.4. We used the spec tab.
• Optic: the spec tab and drawing say the bed is 80 × 60 in; the product description says 75 × 60.
• Matrix: the spec tab calls the bed a Full XL, 80 × 51.5 in; the description calls it queen-size. At 51.5 inches wide it is not a queen.

None of these change the verdicts above. They are the reason to confirm the one number you care about with the brand, in writing, before a non-returnable sofa arrives.

Before you order

1. Measure the room depth from the wall the sofa will stand against to whatever is opposite.
2. Find the opened depth — the frame, not the mattress. If it is not in the spec tab, look for a dimension drawing in the product photos. If there is none, ask.
3. Check which way the bed comes out. Along the wall, the opened depth is roughly the bed’s width. Out from the wall, it is at least the bed’s length.
4. Add 24 inches. If the room is shallower than that, the sofa will open but nobody can walk past it.
5. Find the coffee table a home for the night, and the doorway route for the sofa itself — the method is in our delivery guide. Coddle delivers its sofas fully assembled, so the whole sofa has to make the turns; Burrow’s ship in boxes.

If you take one number away, make it this: a queen sleeper needs about 7 feet of room depth, and a loveseat sleeper needs more. Measure the room for the bed, not for the sofa — the sofa will fit either way.
