# Can I extend my floor sofa into an L-shape or buy extra backrests later?

*Right, then: yes to both. The trick is one small swap in the second order, dear, and it's easy to miss if nobody tells you.*

Also asked as: Can I buy an extension to make it an L-shaped couch?; Can I buy just a single L cushion with a bracket?

> **The quick answer:** A modular floor sofa can be extended into an L-shaped corner couch later by ordering the same sofa again in the same color. The workshop sends that second sofa with two straight backrests instead of its two L-shaped ones, so the pieces combine into an L. Extra straight or L-shaped backrests, and single parts such as a support bar, can be ordered any time.

## Key facts

- Extra straight and L-shaped backrest pillows can be ordered at any time.
- Single parts, such as one L-shaped backrest with one metal support bar, are quoted on request.
- A second sofa can be sent with 2 straight backrests instead of 2 L-shaped ones.
- Colors are matched to your earlier purchase.
- Each floor sofa section is 79 in (200 cm) wide and 39 in (100 cm) deep.

## The L-shape reorder checklist

- ✓ Order the **same sofa** again, in the **same color** as the first.
- ✓ In the note, ask for **2 straight backrests instead of 2 L-shaped** ones on the second sofa.
- ✓ Mention the **earlier order**, so the color is matched to it.
- ✓ Need only one piece? Ask for a quote on **single parts**, such as one L-shaped backrest plus one metal support bar.
- ✓ Tape the corner out first: the standard L-shape is **118 x 79 in (300 x 200 cm)**.

## Why the second sofa needs two straight backrests

Two identical sofas pushed into a corner don't make a tidy L on their own; the backrests have to agree. The first sofa keeps its two L-shaped backrests, the second arrives with two straight ones, and together they form the corner couch. Leave that line out of your note and you'll own a spare pair of L-pieces and a puzzle.

The [modular floor sofa layouts](https://cushionguide.com/guides/modular-floor-sofa-layouts/) show straight, L and U arrangements, and the [support bar notes](https://cushionguide.com/guides/floor-sofa-support-bars-assembly/) cover the [metal support bars](https://cushionguide.com/glossary/#metal-support-bars) that keep the backrests from sliding back. More shapes live in the [modular floor sofa atlas](https://cushionguide.com/cushions/modular-floor-sofas/). Which wall will the second run go on?

## Adding on: what to order for what you want

| You want | Order this |
|---|---|
| A corner couch from one sofa | The same sofa again, same color, with 2 straight backrests instead of 2 L-shaped |
| More back support along a run | Extra straight backrests |
| A spare or replacement corner piece | An L-shaped backrest, plus a support bar if needed |
| A fresh cover for one worn piece | A single cover in your original color |
| An L sized to your walls | Two sofas resized to your runs, e.g. 65 in + 51 in for a 90 x 65 in space |

> **Tailor's margin:** To turn a floor sofa into an L-shape later, reorder the same sofa in the same color and ask for 2 straight backrests instead of the 2 L-shaped ones.

> Extra backrests for a floor sofa can be bought any time, straight or L-shaped, and the color is matched to the earlier purchase.

## Buyer questions

**A common question:** Can I extend my modular floor sofa into an L-shape later and keep the color matching?

**The workshop's answer:** Yes. Order the same couch again in the same color and the shop sends two straight backrests instead of the two L-shaped ones, so the pieces combine into a corner couch. Single parts are sold to match an existing sofa too, such as one L-shaped backrest plus one metal support bar.

**A common question:** Can I buy extra backrest pillows later, one straight and one L-shaped?

**The workshop's answer:** Yes. Extra straight and L-shaped backrest pillows can be ordered at any time.

**A common question:** Can the L-shaped floor sofa be made to fit my wall dimensions?

**The workshop's answer:** Yes. A custom L is built from two sofas resized to your runs, for example 65 in + 51 in for a 90 x 65 in space. Sections stay 39 in deep; 27 in is too narrow once backrests are fitted.

**A common question:** How do I order several pieces in different sizes or colors at once?

**The workshop's answer:** Add each size to your cart as its own item, or ask for one custom listing. For same-size pieces, set the quantity and list each piece's fabric and piping codes in the note; the orders ship together.

## Questions buyers ask next

### How big is the finished L-shaped floor sofa?

The standard closed-corner L is 118 x 79 x 14 in (300 x 200 x 35 cm), built from sections 79 in (200 cm) wide and 39 in (100 cm) deep. If that doesn't fit your walls, the sizes can be customized.

### The metal bars from my first sofa never turned up. What now?

They ship in a separate small box that can arrive on a different day or get overlooked. If they're really missing, send a photo of what you received and ask the workshop to confirm in writing what it will send and when.

### Can I replace one tired cover instead of the whole set?

Yes. Single covers for a base, backrest, corner, armrest or ottoman are sold on their own in your original color, so one torn cover or broken zipper doesn't mean buying a full set.
