# Can you make an L-shaped floor cushion sofa?

*A corner is a question. An L-shaped floor sofa answers it with two sets and one extra backrest.*

Also asked as: Could you do an L-shaped cushion?; Price for a corner sofa? See my diagram.

> **The quick answer:** Yes: an L-shaped floor cushion sofa is made by ordering two floor sofa sets, and the workshop adds the corner backrest free. For any other layout, send a sketch with measurements. One side of the L runs longer so it covers the corner, and round armrest pillows come with L-shaped sets. Small L-shaped daybeds have been made too.

## Key facts

- Two floor sofa sets bought for an L include a free corner backrest.
- One custom corner sofa broke down into 2 floor cushions, 2 backrests, 4 armrests and 1 corner backrest.
- One side of an L must be longer to cover the corner.
- Round armrest pillows come with L-shaped sets.
- L-shaped daybeds with 6 in (15 cm) seats and 5 in (13 cm) backs are made to order.

## Two sets, one corner

Yes. Order two floor sofa sets and the workshop adds the corner backrest free. That is the simplest [L-shaped floor cushion sofa](https://cushionguide.com/cushions/l-shaped-cushions/).

One side must run longer than the other, so it can cover the corner. Round armrest pillows come with L-shaped sets.

For anything else, send a sketch. The [custom shape drawing Pattern](https://cushionguide.com/guides/custom-shape-cushion-drawing/) shows what to mark.

## Before you draw your L

- ✓ Measure both walls, and the floor you want to keep free.
- ✓ Decide which arm runs long; it covers the corner.
- ✓ Mark where each backrest sits: full length, or only at one end.
- ✓ Mark the open ends that need armrests.
- ✓ Note seat and back thickness if the L will also be a daybed.
- ✓ Draw the corner itself, with its corner backrest.

## Three Ls the workshop has built

| Build | Seats | Backrests | Extras |
|---|---|---|---|
| Custom L | 28 x 47 in (70 x 120 cm) and 28 x 55 in (70 x 140 cm) | Full back on the first seat; only 28 in (70 cm) at the end of the second | Round pillows included |
| Corner sofa from a diagram | 2 floor cushions | 2 backrests plus 1 corner backrest | 4 armrests |
| Small L-shaped daybed | 6 in (15 cm) thick | 5 in (13 cm) thick, on the outside edges | Made to order |

## Where the L sits

An L turns a corner into a room of its own. In a [small apartment layout](https://cushionguide.com/concepts/small-apartment-floor-sofa-layouts/), it can wrap a rug and leave the middle open. Leave a hand's width of floor between the long arm and a door swing. The [modular floor sofa atlas](https://cushionguide.com/cushions/modular-floor-sofas/) shows the straight sets it grows from.

Which corner in your home is waiting?

Two sets.
One longer side.
One corner, answered.

> **Tailor's margin:** An L-shaped floor sofa needs one side longer than the other so it covers the corner; two sets bought together come with the corner backrest free.

> Two floor sofa sets make an L and the corner backrest comes free; one custom corner broke down into 2 seats, 2 backrests, 4 armrests and 1 corner back.

## Buyer questions

**A common question:** Can you make a floor sofa in an L shape?

**The workshop's answer:** Yes. Buy two sets and the corner backrest is added free, or order a custom layout. One custom L paired a 28 x 47 in (70 x 120 cm) seat with a full backrest and a 28 x 55 in (70 x 140 cm) seat with a 28 in (70 cm) backrest at the end, round pillows included.

**A common question:** I drew a corner sofa with custom backrests. Can you make it?

**The workshop's answer:** Yes. The diagram became 2 floor cushions, 2 backrests, 4 armrests and 1 corner backrest, and the quote was revised to fit the buyer's budget. A small L-shaped daybed with 6 in seats and 5 in backs has also been made to order.

**A common question:** How big is the corner L-shaped floor sofa?

**The workshop's answer:** It is two 79 x 39 in (200 x 100 cm) sofas joined: 118 in (300 cm) on the long side and about 79 in (200 cm) on the short side, 14 in (35 cm) high. Each seat cushion is 78 x 39 in.

**A common question:** Can the L-shaped floor sofa turn into a bed?

**The workshop's answer:** Yes. Lift off the loose backrests and lay the seat cushions flat side by side; nothing folds out. Pieces arrange as 118 x 39 in (300 x 100 cm) or 79 x 79 in (200 x 200 cm), and the L-shape makes an even bigger bed.

## Questions buyers ask next

### Why must one side of an L-shaped floor sofa be longer?

Because one seat has to reach across the corner. The longer side covers it and the shorter side meets it, so the L reads as one continuous seat rather than two sofas touching at a point.

### Is the corner backrest charged separately when I buy two sets?

No. When two floor sofa sets are bought together to form an L, the workshop adds the corner backrest free. Layouts beyond that are quoted from your sketch.

### Can an L-shaped layout work as a small daybed?

Yes. A small L-shaped daybed with 6 in (15 cm) seats and 5 in (13 cm) backrests along the outside edges has been made to order. Send a sketch with the length of both arms.
