Custom Adirondack Chair Cushions, Made to Your Measurements
Factory-direct, cut to your measurements — standard, oversize and vintage frames.
Adirondack cushions fail on one detail more than any other: the tie pattern. Rear-corner ties need a rear slat or frame bar to fasten to, and on chairs where that slat sits high or low — or the seat tapers wider at the front — stock cushions slide, bunch, or fasten to nothing at all.
We cut Adirondack sets to your frame’s numbers — seat, short lumbar back or full back, throw pillow — with ties placed at your measured slat gaps. Standard 20-inch decks, oversize "king" frames, vintage and handmade chairs, and double tête-à-tête settees are all the same job: numbers in, cushions out.

Pricing — estimated starting at
| Fabric tier | Estimated price* |
|---|---|
| Cotton Linen | $82 |
| Tech Fabric | $85 |
| Premium Velvet | $88 |
*One seat cushion (20 × 20 × 3 in.): $39 make-base + 2.8 sq ft × rate ($15.32/$16.43/$17.56 per sq ft, 3" 50D foam + fabric). Short backs (~20 × 12) and full backs price on their own area; three-piece sets are the sum of their pieces.
For comparison: U.S. custom-configurator specialists’ 2026 listings run made-to-order cushions well above formula price once configured — and most only reveal that number after a quote request. We publish the formula above so you can check the math before you order.
Popular Adirondack Chair Sizes We Cut
Typical Adirondack component sizes (typical, always measure):
| Piece | Typical size | Notes |
|---|---|---|
| Seat cushion | 19 × 19 to 21 × 21, 2–4" thick | 20 × 20 is the de facto standard — stock: 20 × 20, 21 × 21 |
| Short back cushion | ~20 × 12 to 20 × 14 | Covers the lower back only; fits any back height |
| Full back cushion | 20 × 24 to 21 × 30 | Needs the fan or slats to be tall enough |
| Throw pillow | 18 × 18 to 20 × 20 | Optional; sits on top of the back cushion |
| Double / tête-à-tête | Two seats + shared back | Measured as the pieces it actually is |
Yours differs? That’s the point — we cut to your numbers.
How to Measure a Adirondack Chair Cushion
- Seat width and depth — Adirondack decks taper wider at the front more often than not; record front and back widths separately.
- Back height decides short vs full: a short ~20 × 12 lumbar fits any chair; a full back needs the fan or slats to be tall enough.
- Map the slat gaps on seat and back — strapped-back cushions and tie-through fastening need the ties to land in gaps.
- Note the reclined angle’s effect: the back cushion is doing ergonomic work, not decoration — the fan back has no lumbar support of its own.

Fabric for Chairs That Live Outside
Adirondacks sit in the open by design. Tech fabric takes rain and pollen with a wipe-down; premium velvet brings the high-end look and stands up to cat claws; cotton linen suits covered placements. With acrylic-class fabric and foam-core fill, cushions left out all summer last years, not seasons — budget polyester fades within one. The tier-by-tier comparison is in the fabric guide.

Adirondack Frames and Their Cushion Quirks
- The standard wooden Adirondack (seat ~20 × 20, reclined fan back) is the easy case: a stock 20-inch square covers most frames, and the real work is the tie pattern — rear-corner ties need a rear slat or frame bar at the right height, and chairs where that slat sits high or low get ties custom-placed. A short ~20 × 12 lumbar back fits any fan height.
- The oversize “king” frames run 22–24 inch seats with taller, broader fans — a standard pad swims on them. Measure the deck at the front and back (kings taper harder), and let the back height decide short lumbar versus full back before ordering.
- Vintage, handmade and plastic/resin frames follow their builder’s whim, not a chart: resin shells often hide molded contour lines that need tie points at the molded gaps, and handmade chairs vary piece to piece even within one set. The double tête-à-tête settee is measured as what it is — two seats plus a shared back.
Frequently asked questions
Can I order standard Adirondack cushion sizes?
Standard sizes too — in 3 clicks: 20 × 20 is the de facto seat standard — a stock 20 × 20 covers most frames — and typing the numbers into the customizer gets the same instant factory-direct quote. Ties and slat gaps are the part worth measuring; the seat square is usually the easy half.
What size cushion fits a standard Adirondack chair?
A 20 × 20 inch seat cushion fits the majority of standard Adirondacks; 19 × 19 and 21 × 21 cover the rest. For the back, a short ~20 × 12 lumbar style fits any chair, or a full back measured against your back height.
Do Adirondack chairs need back cushions?
Not for fit — only for comfort. Seat-only is the traditional setup; the reclined fan back has no lumbar support of its own, so a back matters if you sit for hours.
Why does my Adirondack cushion keep sliding?
Tie mismatch. Rear-corner ties need a rear slat or frame bar to fasten to; re-tie at frame level where the slat sits high or low, choose four-tie cushions, or have ties custom-placed for odd frames.
Can I leave Adirondack cushions outside all summer?
With acrylic-class fabric and foam-core fill, yes — expect years, not seasons, of life. Budget polyester left out fades within a summer; store those between uses.
Should I get a short back or a full back cushion?
Short — a ~20 × 12 lumbar pad — fits any back height and supports the gap the reclined fan leaves behind your lower back. Full backs (20–21 wide by 24–30 tall) need the fan or slats to be tall enough to fasten to, and they change the chair’s silhouette. Sit hours per session: full back; morning coffee: seat plus short back.
Do resin or plastic Adirondack chairs take the same cushions?
Dimensionally often yes, with one caveat: molded resin shells run contour lines and bolt heads where wooden frames run slats, so tie positions land differently — note the molded gaps on the order. Everything else (deck measure, taper check, thickness) is the identical method.
