Build Your 17 x 17 Cushion

Seventeen inches is the gap in every store’s size run — too odd for the even-number bins, too specific for generic cushion packs. Outdoor frames that take it are real: older bistro sets, compact balconies, children’s patio chairs, and imported lines cut to dimensions that never matched American retail. If your old pad measures between 16.5 and 17.75, no stock shelf has your number; custom cutting does. The square ladder keeps climbing from here — the 23 x 23 lounge square, the 30 x 30 daybed square — each with its own chart.

Every 17 x 17 outdoor cushion is made to your measurements — the exact width, depth, and thickness you enter, sewn to the quarter inch. Keep thickness modest (2.5 to 3.5 inches) so a small frame keeps its designed seat height. All three fabric families available, every fabric one price: Tech Fabric, our waterproof, wipe-clean leather-like weave for full exposure — the outdoor workhorse; Cotton Linen, a durable everyday weave for covered porches and indoors; and Premium Velvet, plush claw-resistant velvet for indoor luxury. Factory-direct, no minimums, one chair or a set of six.

*One cushion, 17 × 17 in. (2.01 sq ft top surface): $45 make-base + 2.01 sq ft × combined foam + fabric rate ($26.47/sq ft in 35D, $27.37 in 50D, $28.69 in 65D, each at the 3-inch default). Every fabric in the 119 lineup carries the same price — choose on looks, not budget. The from-81 entry pairs 35D foam with the thinnest 2-inch cut. Thickness is settled at checkout, and each dimension is confirmed with you before any cutting.

As a yardstick: U.S. specialists running custom configurators priced made-to-order cushions for common sizes (16×16 through 24×24) around $71–$119 before shipping in 2026 — numbers most buyers only see after asking for a quote. We do the opposite: each line of the estimate maps to a size a tape measure can verify.

Striped Canvas - Light brown
  • With the old cushion on a flat surface, take width edge-to-edge, depth front-to-back, and thickness along the seam line. Never measure a pad while it is squeezed.
  • Keep seat height in mind on small frames: every inch of thickness lifts the sitter. Match the old pad’s side.
  • No old cushion? Measure the seat deck between rails and send the raw numbers — don’t round.

Fabric choices at 17 x 17

At 17 x 17 the fabric follows exposure. Open patio: Tech Fabric, waterproof and wipe-clean. Covered porch: Cotton Linen, the breathable natural weave. Screened or indoor: Premium Velvet, plush and claw-resistant. One fabric run per set keeps the dye lots agreed across every chair — the tier-by-tier comparison lives in the outdoor fabric guide.

Thickness & Foam for a 17 x 17

Seventeen inches is the quiet standard between bistro squares and full dining pads — the seat size of countless imported dining sets that never published a chart. Thickness follows the table: 2.5–3 inches keeps dining height honest, with 3 the comfortable default and 2.5 the choice when knee-to-apron clearance is already tight. Match the original pad when you have it; the frame was designed around that number.

Density buys the years: 35D for seasonal sets, 50D for the daily table, and the 60–65D grades reserved for the lounging end of the library. Your grade, thickness and dimensions are confirmed together before cutting — the same written tolerance as every size we make.

The frames that take this square share a trait: they were built small on purpose. French-style bistro sets — the fold-up chairs and round tables of café sidewalks — run 15–17 inch decks. Balcony and small-patio sets from the import years run 16–18. Children’s patio chairs cluster here too, along with the stackable dining chairs that ship with compact sets. None of these frames ever had a deep aftermarket: too small for the mainstream bins, too various for a single stock size, and mostly sold as sets whose pads died with the warranty.

Small frames reward careful thickness more than big ones. A 17-inch deck sits at dining height by design, and every inch of pad is an inch of seat: two-and-a-half to three inches keeps bistro and balcony chairs at their built height; past three-and-a-half the sitter rises toward the table’s edge and the chair’s proportion breaks. Density does the comfort work that thickness cannot — 50D in a 2.5-inch pad outlasts and out-sits a 4-inch low-grade one.

Centimeters and inches

A share of 17-inch searches are really 43-centimeter searches — European and import frames cut to metric, typed into an American search box. The conversions this square cares about: 17 inches is 43.2 cm; 43 × 43 cm measures 16.9 inches square — the same pad; 44 cm is 17.3, still inside a quarter inch; 40 cm (15.7) and 45 cm (17.7) are different families. If your frame’s tag reads metric, convert with the tape measure rather than the formula: lay the old pad flat, read inches edge to edge, and order that. A metric-built frame measured in inches still cuts to the quarter inch — the form takes your number either way.

A few from the 119-fabric lineup — review the full set, zoomed, in the configurator first.

The half-inch family: 17.5, 17 x 18, 18 x 17

A lot of frames that read as “17 by 17” measure out at 17.5 — POLYWOOD adirondack dining and several Duck Covers fits sit on that half inch, which is exactly where stocked pads fail. We cut fractions as standard practice: enter 17.5 x 17, 17 x 18, or 18 x 17 and the bench cuts exactly that, no rounding to the nearest SKU. The same applies to depth and thickness. If your old pad’s label has worn off, measure the cover seam to seam and add nothing — the loft lost over the years is foam, not cover, and the rebuild handles that separately. Pipe-clearing notches are entered the same way, one line each.

Frequently asked questions

Retail stocks even-number sizes; furniture factories didn’t always follow. That mismatch is exactly why custom cutting exists — we make the size your furniture actually takes.

Wipes or washing — covers unzip and remove, so the machine is an option whenever a full wash is due. Tech Fabric is the no-fuss pick: waterproof, cleaned with a damp cloth. Cotton Linen is a spot-clean fabric that takes a low-heat iron on the reverse for creases. Velvet can go to the dry cleaner or into a gentle hand wash, pile brushed flat for drying; Chenille is spot clean only — the tufts are never brushed. The configurator holds all 119 fabrics with weave shots to enlarge first.

Three fabric families, at every size — all one price: Tech Fabric, our waterproof, wipe-clean leather-like weave — the outdoor workhorse; Cotton Linen, a durable everyday weave with no pilling, shrinking, or fading, best under covered patios and indoors; and Premium Velvet, plush high-density velvet with a claw-resistant weave for indoor luxury. A 16-inch square gets the same fabrics as a 60-inch bench pad.
Yes — per-chair line items in one order, one fabric run. Quarter-inch variation between “identical” chairs is common on older imported sets; each pad is cut to its own confirmed numbers, and the set still ships as a matched lot.

Most bistro and balcony decks run 16 to 18 inches, and 17 is exactly where European-cut and import frames land. Every 17×17 outdoor chair cushion we ship is cut to your tape numbers — not the label — so fit is settled by measuring the deck edge to edge and typing what you read. Half-inch decks (17.5) are their own order, not a rounded 17.

For most standard dining frames, yes — 17–19 inch squares cover the majority of patio dining seats. The check that matters is depth: the pad should not overhang the front rail by more than half an inch, and your measured 17 should be a true 17 (not a rounded 17.5).
Yes — convert to inches to the nearest quarter and enter that, or send the centimeter numbers with the order note and we confirm the conversion before cutting. 43 × 43 cm and 17 × 17 inches are the same pad; the confirmation lists whichever units you used, as you used them.
