# Can I buy extra pieces later to turn my floor sofa into an L or a corner sofa?

*A floor sofa can grow with the room. Buy the part you need now. Add the corner when the room asks for it.*

Also asked as: Can I turn it into a sectional?; Add on pieces in the future to make it bigger

> **The quick answer:** Yes, modular floor sofa pieces are sold one by one, so you can add base cushions and straight or L-shaped backrests later to make an L or a corner sofa. Write the exact mix and your color in the personalization box. Moving from a regular sofa to an L is charged as the price difference. Color against an older sofa should be close, not identical.

## Key facts

- Modular floor sofa pieces are sold individually.
- The add-on set holds 2 seat cushions, 1 straight backrest and 1 L-shaped backrest.
- You can change the mix of pieces in the personalization box.
- The 'sofa only' option can have its contents swapped.
- A single sofa or a closed-corner half can be bought on its own.
- Moving from a regular sofa to an L is charged as the price difference.
- Color against an older sofa is close but not guaranteed.

## Can I buy just the missing half of my floor sofa?

Then buy the other half. Order the single sofa and it comes with two straight backrests. Or order the closed-corner half directly.

The add-on set is smaller still: 2 seat cushions, 1 straight backrest and 1 L-shaped backrest. You can also pick the 'sofa only' option and have its contents swapped for the pieces you lack.

## “I want an open L, not a closed corner.”

Write it in the personalization box. For example: 2 long base cushions and 2 straight backrests, no L-shaped backrest, in your color. That leaves the corner as a seat you can step into, an [open corner](https://cushionguide.com/glossary/#open-corner).

The [layouts pattern](https://cushionguide.com/guides/modular-floor-sofa-layouts/) covers straight, L, U and corner plans. Which way does your room turn?

## “Will the new pieces match the old ones?”

Close, not identical. Dye lots vary slightly between orders placed months apart, and the tone against an older sofa isn't guaranteed. The [dye lots pattern](https://cushionguide.com/guides/dye-lots-matching-cushions-later/) explains why.

The cost is simple. Going from a regular sofa to an L is charged as the price difference, and an existing sofa can be completed into a corner sofa with more mattresses, a corner cushion and a straight backrest. See the full range in [modular floor sofas](https://cushionguide.com/cushions/modular-floor-sofas/).

A room changes.
A sofa can follow.
One piece at a time.

> **Tailor's margin:** A modular floor sofa grows by pieces: 2 seat cushions, 1 straight backrest and 1 L-shaped backrest make the add-on set that turns a straight sofa into an L.

> Floor sofa pieces ordered months after the first ones come out close in color, not identical, because dye lots vary slightly between orders.

## Buyer questions

**A common question:** I already own the sofa. Can I buy extra pieces to make it a sectional?

**The workshop's answer:** Yes. Choose the 'sofa only' option and the workshop swaps the contents for what you need, for example a base with 2 straight cushions. Color against an older sofa isn't guaranteed but should be close.

**A common question:** If I buy the regular sofa now, can I add pieces later to make it an L or a corner sofa?

**The workshop's answer:** Yes. You pay the difference and the extra parts are sent. An L-backrest has been quoted together with an extra metal bar, and an existing sofa can be completed into a corner sofa with more mattresses, a corner cushion and a straight backrest.

**A common question:** Can I extend my sofa into an open L in the same teddy fabric?

**The workshop's answer:** Yes. Order through the modular sofa page and write the request in the personalization box, for example 2 long base cushions and 2 straight back pieces instead of L-shaped backrests, in the same teddy fabric.

**A common question:** Can I add an ottoman and a backrest to make my floor sofa a three-seater?

**The workshop's answer:** Yes. The add-on ottoman, 39 x 39 x 13 1/2 in (99 x 99 x 34 cm), ships with a straight backrest and a metal bar. Add a corner backrest instead to make an L.

## Questions buyers ask next

### Does the L have to turn to the right?

No. The sectional has no fixed direction, so the chaise, open end or ottoman can sit on either side. Move the L-shaped backrest to the other corner.

### Is the upgrade priced as a whole new sofa?

No. Moving from a regular floor sofa to an L-shape is charged as the price difference, and only the extra parts are sent to complete the set you already have.

### What size floor sofa seats three people?

Choose 28 x 64 in (about 71 x 163 cm). The photos mostly show 28 x 56 in (70 x 140 cm), and any length can be made to order.
