Outdoor Seat Cushions, Custom Cut to Your Measurements
Factory-direct, cut to your measurements — wicker, wrought iron, wood and lawn frames, any seat deck.
Every piece of outdoor furniture, whatever it is called on the tag, shares one working part: the seat pad. It carries the body, takes the weather, and dies first — usually two or three seasons before the frame shows its age. Outdoor seat cushion replacement is the steady heartbeat under the whole outdoor word family: deep seating, dining sets, porch rockers and lawn chairs all come down to a pad cut to fit a seat deck that nobody mass-produces for.
And the decks are the problem. Wicker seats taper toward the back and curve at the front. Wrought iron runs narrow with rounded rear rails. Wood slats space their gaps wherever the joiner set them. The universal pad on the hardware-store shelf is a square with four ties, and it fits all of these the same way: approximately. This page is the seat-pad answer: measure your deck, name your fabric, and we cut an outdoor seat cushion to your numbers — squares, rounds, trapezoids, saddles — with ties that land where your frame can actually fasten them.
Build Your Outdoor Seat Cushion
Build your outdoor seat cushion — start with the shape below.
Squares and rectangles for dining and wood frames, rounds for stools, trapezoids for wicker decks that run wider at the front. Pick the shape, type your numbers, and the estimate appears as you type — seat pads and matching backs can ride in one order.
Wicker, iron, wood, lawn — every outdoor seat is the same job: pick a shape and type your numbers.
Pricing — estimated starting at
| Fabric tier | Estimated price* |
|---|---|
| Cotton Linen | $77 |
| Tech Fabric | $80 |
| Premium Velvet | $83 |
*One outdoor seat pad (18 × 20 × 3 in.): $39 make-base + 2.5 sq ft × rate ($15.32/$16.43/$17.56 per sq ft, 3" 50D foam + fabric). Rounds, trapezoids and matching back pads price on their own area at the same formula — every seat, one calculator.
For comparison: big-box seat pads run $10–$25 in a handful of sizes — thin fiber fills that flatten inside a season and fit approximately. We publish the formula above so you can check the math before you order.

Yours differs? That’s the point — we cut to your numbers.
How to Measure an Outdoor Seat Cushion
- Measure the seat deck between the rails, arms and back supports — not the old cushion and not the frame’s outside edges; width and depth to the nearest quarter inch.
- Tapered wicker decks get two numbers: front width and back width, entered separately — a single average is how a pad ends up gapping at one end.
- Check the fastening points while the tape is out: weave openings on wicker, crossbars on iron, slat gaps on wood — ties only hold where the frame can catch them.
- Mismatched sets are normal: measure each chair that differs, even in one run — factory chairs drift more than the catalog admits.

Waterproof or Weather-Resistant? Fabric by Exposure
Two honest grades, matched to where the chair lives. Weather-resistant weaves shed light rain and morning dew — the right spec for covered porches, gazebos and furniture that winters inside. Waterproof builds — our Tech Fabric face over a foam core — take the open deck: full sun, sprinklers, the storm nobody forecast. In color-holding, solution-dyed acrylic is the grade outdoor specialists build their names on; budget polyester fades in one strong summer. The tier-by-tier comparison lives in our outdoor fabric guide.
Under the cover, the same logic decides drying: a foam core drains and airs out from the inside, where a fiber-only pad soaks and compacts — the difference shows up in season two.
We Build for Wicker, Iron and Wood Frames
The material of the frame changes the job — each one gets its own answers:
| Your frame is… | What changes |
|---|---|
| Wicker or rattan | Tapered decks cut as trapezoids, curved fronts eased, ties looped through the weave openings — wicker cushions |
| Wrought or cast iron | Narrow decks, rounded rear rails followed inch by inch, ties set at the crossbars — wrought iron cushions |
| Wood slats & adirondacks | Square decks with tie-throughs at the slat gaps, fan-back sets with custom tie placement — Adirondack cushions |
| Lawn & sling chairs | Thin 2–2.5" pads that don’t fight the low seat, ties at the frame bars — lawn furniture cushions |
| Rockers & gliders | Motion-duty builds with reinforced ties that survive the swing arc — rocking chair cushions |
| A whole mixed set | Every frame type in one order, one fabric tier, one dye lot — each piece priced on its own area |
Not sure which page your chair belongs on? It belongs on this one — a seat pad is a seat pad, and the frame pages carry the deeper build notes.
Frequently asked questions
What size outdoor seat cushion do I need?
Measure your own seat deck: dining chairs and lawn chairs run 16–20 inches wide and 16–20 deep, wicker decks taper and need front and back widths, and stools go round. The frame decides the number — the size words on a stock tag only describe the average chair.
How do I replace outdoor seat cushions?
Pull the old pad, measure the deck underneath edge to edge, match thickness to the chair type, pick a weatherproof fabric, and order to your numbers. Replacement is the normal case — frames outlast their cushions roughly five to one.
Waterproof or weather-resistant — which do I need?
Weather-resistant fabric sheds light rain and morning dew — right for covered porches and furniture you store in winter. A waterproof weave over a foam core is the open-deck spec: it takes the sprinkler and the surprise storm and dries from the inside. Full exposure, waterproof; partial shelter, weather-resistant.
How do seat cushions fasten to wicker, iron and wood frames?
Wicker takes ties through the weave openings, iron frames take ties at the crossbars, and wood slats take tie-throughs at the gaps or an anti-slip underside on solid decks. Name the fastening points with your measurements and the ties land there.
Why do you cut to my exact number instead of adding ease?
A pad cut loose slides, cups at the edges and rides up in the wind — the complaint stock cushions earn every season. We cut to your confirmed dimensions, in writing, to ±½ inch, so the pad lands on the deck and stays. Outside tolerance, remade free.
What thickness should an outdoor seat cushion be?
2.5–3 inches is the dining and wicker standard; sling and lawn chairs sit tight at 2–2.5; deep-seating decks run 5–6 because the lounging posture sinks in. The frame’s seat height sets the ceiling — measure the arm-to-seat gap before choosing loft.
Can I order seat and back cushions in one matched set?
Yes — seats and matching back pads in the same fabric tier ship from the same dye lot, and each piece prices on its own area. Odd numbers are fine: a set of four and a spare, or one lone chair the set left behind.
