# Can I buy just the L-shaped corner backrests without the sofa?

*A corner back is the piece that turns a mattress into a place to sit up and talk. You can have it on its own.*

Also asked as: Can I only get the L-shaped backrests?; Order just the L-shaped cushions.

> **The quick answer:** Yes, L-shaped backrests are sold on their own: choose the L-shaped backrest option on the listing or ask for a custom link. Each covers a 39 x 39 in (100 x 100 cm) corner and stands about 15 in high, so two span a 39 x 79 in sofa or turn a twin daybed into one. They have no hook-and-loop, and bars are sold separately.

## Key facts

- L-shaped backrests are sold individually.
- Each is 39 x 39 in (100 x 100 cm) along the L and about 15 in (39 cm) high.
- Two L-shaped backrests span a 39 x 79 in (100 x 200 cm) sofa.
- They have no hook-and-loop or other attachments.
- Metal bars and brackets are sold separately.
- Covers alone for two L-shaped backrests are available.

## Before you order corner backs on their own

- ✓ Your base: a modular floor sofa, twin mattresses, or a daybed about 75 x 38 in (191 x 97 cm)
- ✓ Corner coverage: 39 x 39 in (100 x 100 cm) per L-shaped backrest
- ✓ Two backrests for a 39 x 79 in (100 x 200 cm) seat
- ✓ 'L-shaped backrest' picked from the listing options, or a custom link requested
- ✓ Bars or brackets added if nothing stands behind your base
- ✓ Covers only, if your inserts are still good

## What an L-backrest doesn't include

- ✗ No hook-and-loop or other attachments; it stands free
- ✗ No metal bars; those are a separate purchase
- ✗ No seat cushion; the backrest is the top piece only
- ✗ Not a compact reading chair; the corduroy pouf chair suits that better

## A back that stands on its own

A seam is a promise, and an L-shaped backrest keeps it without help. There's no hook-and-loop on it and nothing to fasten, so it sits wherever you put it: on your own modular sofa, on a pair of twin mattresses, on a daybed from another maker. One buyer set two on a 75 x 38 in daybed from another brand.

If the back has nothing to lean on, add bars. One order paired two L-shaped inserts with four metal brackets for a buyer's own twin mattresses. Backrests can be made slimmer, though a thinner back is less durable, and the height isn't cut down, because the height is what holds you up.

What will your corner backs lean against, my friend?

> **Tailor's margin:** Two L-shaped backrests, each 39 x 39 in along the L and about 15 in high, turn a twin mattress into a sofa.

> An L-shaped backrest has no hook-and-loop and no bars attached: at 39 x 39 in, the corner back stands free on your own mattress or modular sofa.

## Buyer questions

**A common question:** Do your L-shaped backrests have hook-and-loop, or can I use them on my own modular sofa?

**The workshop's answer:** They have no attachments at all, so they work anywhere as standalone cushions. Each L-shaped backrest measures 39 x 39 in (100 x 100 cm) along the L.

**A common question:** Can I buy only the L-shaped backrests for a daybed from another brand?

**The workshop's answer:** Yes. Choose 'L-shaped backrest' from the options. Each covers a 39 x 39 in corner, so two cover a 39 x 79 in sofa; one buyer used them on a 75 x 38 in daybed.

**A common question:** Could one L-shaped backrest work as a reading chair on its own?

**The workshop's answer:** For a compact reading chair the workshop recommended its corduroy pouf chair instead of a single L backrest. The backrest is the top cushion only, and bars are sold separately.

**A common question:** Can I buy just the backrest inserts and the bars for my own twin mattresses?

**The workshop's answer:** Yes. Two L-shaped backrest inserts and four metal brackets were sold together through a custom listing link.

**A common question:** Could I order covers only for two L-shaped backrests?

**The workshop's answer:** Yes. Covers alone for two L-shaped backrests are available, and they're the cheaper route when your inserts are still good.

## Questions buyers ask next

### Can an L-shaped corner backrest be made thinner?

Yes, backrests can be made slimmer, though thinner backs are less durable. The height isn't reduced, since it's what supports the sitter, and taller corner backs weren't workable.

### How do corner backrests turn a twin daybed into a sofa?

Set two L-shaped backrests on the mattress so they wrap the corners; each covers 39 x 39 in, and together they span a 39 x 79 in seat. Two straight 18 x 36 in backrests plus two armrests are the other route for a twin.

### Are the metal bars required with L-shaped backrests?

Not to buy the backrests; bars are sold separately. They stand behind the backrests on the floor and stop them sliding or tipping back, which matters most when no wall stands behind the sofa.
