# Around the fire pit: cushions for curved and L-shaped patio benches

*Fire pit benches curve, turn corners and sit on stone. Eight real patio projects, each with the drawing it needed and the weather it has to take.*

> **The quick answer:** Fire pit bench cushions should be plain foam cushions in water-repellent outdoor fabric, cut in segments you can carry. Measure a curved bench with a string along the outer and inner curves, plus the straight distance across each and the depth. Split an L-shaped bench into two seats at the corner. Skip tufting: every tuft lets rain into the foam.

## Curves, L's and stone, out in the weather

Nobody builds a fire pit bench square. It curves around the flames, turns an L at the edge of the patio, or it's poured concrete with a drain cut through it. Fire pit bench cushions have to follow all of that, then come inside when the season ends.

Five rules came out of past patio projects:

- **Measure a curve with a string.** Both arcs, the straight distance across each, and the depth in more than one spot; the [curved cushion Pattern](https://cushionguide.com/guides/curved-cushion-chord-rise-radius/) has the math.
- **Cut long runs into pieces you can carry.** A 125 in (318 cm) bench went in two; a 245 in (622 cm) curve went in four.
- **Leave tufting indoors.** Rain doesn't negotiate, and every tuft is a way in for water.
- **Seat an L as two cushions.** They meet at the corner, and the covers come off easily.
- **Tie down anything in the wind.** Ties and hook-and-loop straps are added only when you ask.

One more, friend: give the fire its own room. Stack the cushions well back from sparks before a big blaze, and keep them off hot stone.

The [outdoor cushions](https://cushionguide.com/cushions/outdoor-cushions/) hub covers fabric and foam, and [patio and porch cushions](https://cushionguide.com/cushions/patio-and-porch-cushions/) the rest of the backyard. Straight runs can be sized in the [bench cushion builder](https://cushionguide.com/studio/bench-cushion-builder/). How long is the front edge of your bench?

## Eight benches around the fire, each with its drawing

### 01. A 245 in curve, measured with a string

![Four brick red curved cushions on wicker benches arranged in a circle around a round teak coffee table under a pergola](https://cushionguide.com/media/outdoor-cushions/four-red-curved-bench-cushions-pergola-circle-1600.webp "Four arc-shaped cushions make a full conversation circle, each one sized to its own wicker section.")

A buyer in the US measured a curved stone bench around a fire pit with a piece of string. The workshop asked for the inner curve, the outer curve, the depth at several points and the straight distances end to end: 142 in (361 cm) at the back, 117 in (297 cm) at the front. The drawing came out at a 245 in (622 cm) outer curve, a 208 in (528 cm) inner curve, 12.75 in (32 cm) deep and 3 in (7.5 cm) thick, made as four symmetrical segments for handling and storage.

**The takeaway:** Give both arcs and both straight chords; together they let the maker rebuild the exact curve.

> **Tailor's margin:** A 245 in (622 cm) curved fire pit cushion was made as four symmetrical segments, for handling and storage.

### 02. A concrete L, seated in two pieces

![Close view of red and cream ticking-stripe corner banquette cushions with self-piping cut from the same striped fabric](https://cushionguide.com/media/l-shaped-cushions/red-ticking-stripe-corner-seat-self-piping-closeup-1600.webp "Self-piping cut from the ticking stripe wraps every edge of this corner seat in the same pattern.")

A buyer in the US sent photos and a diagram of an L-shaped concrete fire pit bench with an 18 in (46 cm) deep seat, and picked a striped outdoor fabric. They ordered seats only, with the piping matched to the gray stripe. The workshop made two separate seat cushions instead of one L piece, so the covers come off easily and stay snug. The buyer called the result perfect.

**The takeaway:** An L-shaped bench takes two seats that meet at the corner; match the piping to one color in the stripe.

> **Tailor's margin:** An L-shaped fire pit bench seats better as two cushions meeting at the corner than as one L-shaped piece.

### 03. Pool and fire pit benches, tufting turned down

![Ivory outdoor seat and back cushions with fine taupe pinstripes on a teak armless lounge chair on a limestone pool terrace](https://cushionguide.com/media/outdoor-cushions/ivory-pinstripe-deep-seat-cushions-teak-pool-chair-1600.webp "Fine vertical pinstripes on thick ivory cushions keep a teak lounge chair crisp beside the pool.")

A family in the US wanted tufted floor-style cushions for three benches by a pool and fire pit: one at 125 x 20.5 x 3 in (318 x 52 x 7.5 cm) and two at 86.75 x 20.5 x 3 in (220 x 52 x 7.5 cm). The workshop warned that tufting lets water in even with outdoor fabric, and suggested plain foam-filled cushions. The 125 in run was made in two pieces, each about 62.6 in (159 cm).

**The takeaway:** Outdoors, choose plain foam over tufts; a tuft is a stitched path straight into the foam.

> **Tailor's margin:** Tufting on a pool or fire pit bench lets rain into the foam, even in outdoor fabric; choose plain foam.

### 04. Stone seats around the fire, photos first

![Charcoal and white crackle-pattern outdoor cushion on a stone and cedar bench by a fire pit at dusk with whisky glasses](https://cushionguide.com/media/outdoor-cushions/charcoal-crackle-cushion-stone-bench-fire-pit-1600.webp "A charcoal outdoor cushion made for evenings by the fire, on a stacked-stone bench capped with cedar.")

One buyer wrote in about stone seats set around a fire pit: six squares of 18 to 20 in (46 to 51 cm) and two wider seats of about 31.5 in (80 cm). Masonry is rarely even, so the workshop asked for photos before sizes. The colors settled on beige with olive or eucalyptus green.

**The takeaway:** Send a photo of every stone seat along with its numbers; the photo shows what the tape can't.

> **Tailor's margin:** Masonry seats are rarely square: send a photo of each 18 to 20 in (46 to 51 cm) stone seat.

### 05. A built-in bench with a drain cut through it

![Brick red curved outdoor bench cushion with self piping on a natural resin wicker bench, deck with ferns and lantern behind](https://cushionguide.com/media/outdoor-cushions/brick-red-curved-cushion-natural-wicker-bench-deck-1600.webp "One piece of brick-red outdoor fabric, cut to an arc, turns a curved wicker bench into proper seating.")

A buyer wrote to the workshop with a big built-in outdoor bench that had a drain cutout. The workshop read the drawing back as a numbered list of the figures still missing, and only then drew the cushions: 3 in (7.5 cm) seats, 8 in (20 cm) bolsters, and one 142 in (361 cm) bolster made in two pieces.

**The takeaway:** When the maker sends back a numbered list of missing figures, answer every number; a cutout can't be placed without them.

> **Tailor's margin:** A 142 in (361 cm) outdoor bolster is made in two pieces, just like a long bench seat.

### 06. A windy patio: wedge backs and straps

![Charcoal gray box cushions on a wicker rooftop sofa with herringbone and ivory pillows, city skyline at sunset](https://cushionguide.com/media/outdoor-cushions/charcoal-rooftop-sofa-cushions-city-skyline-sunset-1600.webp "Charcoal cushions keep a rooftop sofa looking tidy through soot and rain; texture comes from the knit and lumbar pillows.")

One buyer wrote in about a windy patio: two 33 x 30 x 4 in (84 x 76 x 10 cm) seats and two 32 x 13 in (81 x 33 cm) backs, thicker at the bottom like a wedge, held down with ties or hook-and-loop straps. They asked for Sunbrella by name. That isn't a fabric the workshop carries; its outdoor line is a UV-resistant, water-repellent polyester, and samples went out before the order.

**The takeaway:** In wind, put ties or straps on the order with their position and length; they are added only on request.

> **Tailor's margin:** Patio cushions in wind need ties or hook-and-loop straps, sewn on only when the order asks for them.

### 07. A five-seat pool bench: one, two or five

![Stack of three white outdoor cushions in navy, taupe and coral stripes on terracotta tiles beside potted rosemary and thyme](https://cushionguide.com/media/outdoor-cushions/striped-outdoor-cushion-stack-potted-herbs-terracotta-1600.webp "Kept stacked in a corner among the herb pots, spare outdoor cushions double as extra seats when friends arrive.")

A buyer got in touch about a five-seat pool bench about 118 x 19.7 in (300 x 50 cm), 5 in (13 cm) thick. There were three honest ways to cut it: one long piece that folds for storage, two pieces, or five, one for each seat.

**The takeaway:** Pick the split by where the cushions spend the winter. One long piece folds; two or five carry in one at a time.

> **Tailor's margin:** A 118 in (300 cm) pool bench cushion can be one folding piece, two halves or five seats.

### 08. Storage lids, snowy winters and a plain answer

![Side profile of oat velvet box seat and back cushion with lavender piping and a zipper tab on a white banquette](https://cushionguide.com/media/l-shaped-cushions/cream-velvet-lilac-piped-bench-seat-side-profile-1600.webp "The side view shows the box depth, the leaning back pad and the zipper tab of a velvet banquette set.")

A buyer in the US, with hot summers and snowy winters, sent drawings of outdoor storage benches with lift-up lids and asked for the cushions split at the lid lines. One run was about 1.5 in (4 cm) off in depth, so the workshop asked for a full drawing of each piece. The workshop also told her plainly: no fast-drying mesh bottom, no quick-dry foam, and a fabric suited to a covered porch or indoor winter storage. The seats were 3 in (7.5 cm) thick.

**The takeaway:** Over lift-up lids, split the cushion at every lid line and draw each piece on its own.

> **Tailor's margin:** Split a storage bench cushion at every lid line; a 1.5 in (4 cm) depth change means separate drawings.

## What buyers ask for, and what the workshop makes instead

Honest answers save a season. [Water-repellent fabrics](https://cushionguide.com/fabrics/water-repellent-membrane/) in the Swatch Library explain the cloth, the [outdoor fabric comparison](https://cushionguide.com/guides/outdoor-cushion-fabric-acrylic-olefin-polyester/) sets acrylic, olefin and polyester side by side, and [winter storage](https://cushionguide.com/guides/outdoor-cushion-care-winter-storage/) covers the off-season.

| Buyers ask for | What the workshop makes | Why |
|---|---|---|
| Sunbrella by name | The workshop's own UV-resistant, water-repellent polyester outdoor fabric, 100+ colors | The workshop doesn't stock the brand; samples can go out before you order |
| Quick-dry foam or a mesh bottom | Outdoor-suitable foam inserts in zippered covers | Neither is offered; the line suits covered spots and indoor winter storage |
| A tufted outdoor seat | Plain, non-tufted foam cushions | Tufts let water in, even through outdoor fabric |
| One L-shaped piece | Two seats meeting at the corner | Covers come off easily and stay snug |
| One cushion for a 125 in or 245 in run | Two to four segments | Handling and storage |
| Waterproof | Water-repellent fabric that sheds showers and spills | Not a sealed, coated cloth; store indoors off-season |

## Straight: weather, curves and fabric

**A common question:** Will rain soak straight through the outdoor cushions on a fire pit bench?

**The workshop's answer:** Outdoor cushions are made from a separate water-repellent fabric range with its own color chart, which the workshop sends on request. In practice the fabric is water-resistant rather than a sealed, coated material: it handles rain showers and spills well, and outdoor seats and backs get outdoor-suitable inserts. For a big patio you can order one cushion first to check the fit. Like any outdoor textile, store them indoors over the long off-season.

**A common question:** Can I put velvet or linen cushions on a stone bench outside?

**The workshop's answer:** No. The indoor fabrics, including linen, velvet and chenille, aren't made for open-air use, and chenille in particular doesn't belong outside in humid weather. Outdoor-performance fabrics resist moisture, mildew and mold far better. Order through the outdoor range instead: 100+ outdoor-rated, UV-resistant colors, in any color and piping combination. When indoor cushions were ordered for outdoor use by mistake, the workshop cancelled and refunded so they could be reordered correctly.

**A common question:** Can you make a cushion for a curved spot rather than a straight bench?

**The workshop's answer:** Yes. Send the shape and measurements before you order, with a sketch and a few photos of the space taken from a distance, so everything is agreed first. For a quarter-round or curved shape the workshop needs the two straight sides to calculate the curve. The workshop says up front whether a size-based customization fee applies; large custom shapes are priced for their size and cut rather than at standard-cushion prices.

**A common question:** The chair pads I like only list indoor fabrics. Can they match my outdoor bench cushion?

**The workshop's answer:** Yes. Most cushions can be made in outdoor fabric. Pick a code from the outdoor color charts, which the workshop sends on request, then order the shape you want, whether chair pads, square cushions or even a star floor cushion, and write the outdoor code in the order note. Every piece is then made in the same outdoor fabric, so the chair pads and square cushions match the bench.

## Questions buyers ask next

### Why shouldn't a fire pit bench cushion be tufted?

Tufting stitches right through the cushion, and those stitch points let water in even when the fabric is outdoor-grade. For three benches by a pool and fire pit, the workshop steered a family in the US from tufted floor-style cushions to plain foam-filled ones for exactly that reason.

### How do you measure a round or curved fire pit bench?

Run a string along the outer curve and the inner curve, then measure the straight distance across each and the depth at several points. One curved stone bench came out at 245 in (622 cm) outside, 208 in (528 cm) inside and 12.75 in (32 cm) deep.

### When does a long outdoor bench cushion get split into pieces?

When one piece becomes hard to handle and store. A 125 in (318 cm) bench cushion was made in two pieces of about 62.6 in (159 cm), a 142 in (361 cm) bolster in two, and a 245 in (622 cm) curve in four symmetrical segments.

### What keeps fire pit cushions in place when the wind picks up?

Ties or hook-and-loop straps sewn into the seams, which are added only on request, so give their position and length in writing. A non-slip base helps on smooth surfaces. Every order is photographed before it ships; check that photo to confirm the extras are there.
