Custom Outdoor Seat Cushions

Build Your Outdoor Seat Cushion

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 — sized to sit the deck without wandering.

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

*One outdoor seat pad (18 × 20 × 3 in.): $45 make-base + 2.5 sq ft × rate ($27.37 per sq ft, 3" 50D foam + fabric, all fabrics one price). Rounds, trapezoids and matching back pads price on their own area at the same formula — every seat, one calculator.

Every price covers foam, fabric and make — shipping is a single flat rate per order with tracking, and nothing is cut until you confirm the numbers. Your order starts the clock at the cutting table: made in 4–7 business days, rush production 3–5, delivered in 3–6 weeks door to door.

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. No hidden markups: each part of the estimate maps to a size you can verify with a tape measure.

Common Outdoor Seat Cushion Sizes We Cut

Typical decks by frame type (typical, always measure):

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.
• 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.

Quick-Dry Options for Wet Weather

“Truly waterproof” is a three-layer question, not a fabric question. The face fabric sheds what it can. The foam core decides whether the water that gets in can get back out. And the sewing decides how much gets in: every seam is a row of needle perforations, the zipper exists so the cover can be washed — and admits sideways rain every time it blows — and an uncoated underside drinks from a wet sling. No factory closes those three doors. The honest spec is not “water never gets in”; it is “water leaves fast.”

That is what our standard outdoor build already does: a high-density foam core under a waterproof, wipe-clean face drains and airs out from the inside, so the interior never stays damp long enough for mildew to establish. “Mildew resistant,” on a sewn cushion, means fast drying by geometry — not a chemical claim — and it is why a foam core outlives a fiber-only pad that soaks and compacts by season two.

Cushions that live uncovered in the rain — pool furniture, marine seating, fully exposed sets in wet climates — have one correct core: reticulated quick-dry foam, processed so every cell window is removed and rain pours straight through in seconds. We will be straight with you: our menu runs high-density foam in four grades (35D–65D) under waterproof faces — the right build for sheltered and semi-exposed seating — and for uncovered-in-the-rain duty we would rather you buy the right fill from a marine specialist than the wrong fill here. What “waterproof” does and does not mean on a sewn cushion is unpacked in waterproof cushions explained, and the full material science of quick-dry foam is in the quick-dry foam guide.

The habit that outperforms any spec: after a soaking, stand cushions on edge with the lowest seam down and unzip the cover — two minutes of gravity and airflow dries both faces and prevents most saturation events. The full rescue routine for a cushion that did get soaked is in how to drain waterlogged cushions.

We Build for Wicker, Iron and Wood Frames

The material of the frame changes the job — each one gets its own answers:

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?

By exact fit, not sewn fasteners — we don’t sew on ties or gripper undersides. A pad cut to your confirmed numbers sits the deck without wandering, on wicker, iron and wood alike. Where a chair gets dragged around, a thin non-slip rug pad trimmed slightly smaller than the cushion, laid flat underneath, is the honest fix.

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.

How long does a custom outdoor seat cushion take?

Made to order in 4–7 business days — rush production is 3–5 business days for a surcharge — delivered in 3–6 weeks door to door. Typical US custom shops quote 3–6 weeks for the same build; we publish the number instead of burying it in a quote.

Do your cushions come with piping or welt cord?

Not as a standing option. Our sewing standard is clean, cord-free knife-edge seams — no decorative cord on any shape, any fabric. The flat profile wears evenly at the corners, cleans flat, and never traps debris along a raised seam.

Where are your cushions made?

In our own overseas factory — cut and sewn to your measurements, shipped factory-direct to your door. What decides how long a seat cushion lasts isn’t the country on the label; it’s foam density (we build on 50–65D foam), the fabric family (solution-dyed acrylic for chairs that live in the sun), and seam construction — and we publish the numbers for all three. Factory-direct is why the same spec costs 40–60% less than a local shop: no middleman, no warehouse, no storefront. If made-in-USA is a hard requirement, a local upholsterer is the right call — budget 2–3x for US labor hours. Every order is made in 4–7 days, arrives in 3–6 weeks, and is backed by our free remake guarantee.

Is a Custom Outdoor Seat Cushion Right for You?

• Weather-resistant is not waterproof. Light rain and morning dew is the weather-resistant brief — covered porches and winter-stored furniture. Open decks take the waterproof weave over a foam core; choosing the lighter spec for full exposure is how pads die in season two.
• Day to day, plan on spot cleaning. Covers close with a zipper around the fill, so cleaning is a damp cloth and mild soap between washes — and the cover comes off for a full wash. The fabric spec is chosen for wipes; the washer is not part of the care plan.
• Unsure about color? Email before you order. Screens shift color and afternoon sun shifts it again — send a photo of where the piece will live and we will answer honestly how each fabric reads in that spot. Two minutes of email beats a wrong-color guess on a non-returnable cut.
• Custom-cut means non-returnable. A cushion cut to your numbers fits exactly one frame on earth. Tolerances are published in writing (±½″, ±¾″ over 36″); anything outside them against your confirmed numbers is remade free, whenever the error turns up.

Made by the factory that ships them

• Outdoor cushion factory for 10+ years — we cut, fill, and sew every order ourselves.
• Every dimension you send is re-checked before a single yard of fabric is cut.
• Made-to-order means any fabric, any piece, no minimum.
• Cut to ± ½ inch of your confirmed dimensions, in writing — outside tolerance, remade free.
