# Can you make cushions for my built-in couch, daybed or mattress to turn it into a sofa?

*A built-in bench is already a sofa. It is only missing the soft parts.*

Also asked as: Can you make cushions for a concrete couch?; My daybed should look more like a couch.

> **The quick answer:** Yes, cushions for a built-in concrete couch, a daybed or a mattress sofa are made to order from your measurements or a sketch, as seats, back cushions and bolsters, quoted as a set; the quote states the shipping cost. One concrete couch took three 23.5 x 27.5 x 4 in (60 x 70 x 10 cm) seats, an 83 in (211 cm) back cushion and two cylinder armrests.

## What to send for a built-in quote

- ✓ Each seat: length, depth and thickness, e.g. 23.5 x 27.5 x 4 in (60 x 70 x 10 cm)
- ✓ The back: full length, height and thickness, e.g. 83 x 14 x 2 in (211 x 35 x 5 cm)
- ✓ The arms: bolster length, e.g. 23.5 in (60 cm) cylinders
- ✓ A simple drawing if it is a mattress or an odd layout
- ✓ Your fabric; ask for color photos and the linen chart

## Four built-ins and the cushion sets made for them

| You have | What was made | Note |
|---|---|---|
| A built-in concrete couch | 3 seats, 1 long back, 2 cylinder armrests | Mint and beige photographed, linen charts sent |
| A floor seating plan | 3 seats and 3 backs at 63 x 23.5 x 4 in (160 x 60 x 10 cm) | Foam, sewn covers and delivery quoted together that time |
| A daybed | 2 seat covers and 2 filled angled backrests | Buyer's choice of color |
| A queen mattress, 60 x 80 in | Sewn-closed cover, backrest, arm bolsters | Made from a drawing, flat or tufted |

## The mattress that became a sofa

A buyer sent a drawing of a queen mattress, 60 x 80 in (152 x 203 cm), and asked for a sofa.

The cover was sewn closed like a [French quilted mattress](https://cushionguide.com/glossary/#french-mattress-cushion). No zipper. Flat or tufted, as they chose. The backrest and armrests were French-style, with buttons.

One mattress. A cover, a back, two arms. A different room.

## Measure the structure, not the idea of it

A built-in is measured piece by piece. Each seat on its own, then the back, then the arms. The workshop quotes from those numbers, or from a sketch, and the quote lists foam, custom-sewn covers in your fabric and the shipping cost.

For a daybed, you may need less than you think: seat covers and filled angled backrests are enough to read as a couch. The [daybed styling Pattern](https://cushionguide.com/guides/daybed-back-cushions-sofa-look/) and the [daybed cushion sets](https://cushionguide.com/concepts/daybed-sofa-cushion-sets/) show real builds, and [daybed cushions](https://cushionguide.com/cushions/daybed-cushions/) collects the shapes.

What is your built-in made of, and how deep is the seat?

> **Tailor's margin:** For a built-in couch, measure every seat, the back and the arms separately; one concrete couch needed three 23.5 x 27.5 in seats and an 83 in back.

> A daybed can look like a couch with two things added: seat covers and filled angled backrests, sized to the daybed you already own.

## Buyer questions

**A common question:** Can you make cushions for a built-in concrete or masonry couch?

**The workshop's answer:** Yes. Three 23.5 x 27.5 x 4 in (60 x 70 x 10 cm) seats, an 83 x 14 x 2 in (211 x 35 x 5 cm) back cushion and two 23.5 in (60 cm) cylinder armrests were quoted as one set. The shop sent photos of mint and beige plus linen color charts.

**A common question:** Three seats with matching backs at 63 x 23½ x 4 in (160 x 60 x 10 cm): is delivery in the price?

**The workshop's answer:** In that case, yes: the quote for three seat cushions and three back cushions at 63 x 23.5 x 4 in (160 x 60 x 10 cm) included the foam, custom-sewn covers in the chosen fabric and delivery. Check the shipping line on your own quote.

**A common question:** I already own a daybed. Can I buy floor-sofa covers and the filled angled backrests so it looks like a couch?

**The workshop's answer:** Yes. Two filled backrest pillows plus two seat covers were quoted as a set, in the buyer's choice of color.

**A common question:** Can a floor cushion sofa double as a bed?

**The workshop's answer:** Yes. Floor cushions are soft yet supportive enough to sleep on, can be joined into a double bed or made in bed sizes, and the soft fabric is recommended over linen for regular sleeping.

## Questions buyers ask next

### Do I need a drawing, or are measurements enough?

Measurements are enough for straight seats and backs. For a mattress turned sofa or an odd layout, a simple drawing with each piece labeled helps the workshop quote the right set the first time.

### Does the cover on a mattress sofa have a zipper?

No. The mattress cover is sewn closed like a French quilted mattress, flat or tufted, and the backrest and armrests are made French-style with buttons to match the look.

### Can I see the fabric in real color before choosing?

Yes. The workshop sends color photos and linen charts; for one concrete couch it photographed mint and beige for the buyer. Order swatches too if the exact shade matters in your light.
