Wicker Furniture Cushions: Selection & Replacement Guide

Wicker furniture is where universal cushions go to fail. The frames are generous, the seat decks are deep, the backs are tall — and most off-the-shelf cushions are cut for none of that. This guide covers wicker cushion dimensions by furniture type, the fit problems specific to wicker (seat depth, back height, one-piece benches), fabric and fill choices for weave-through weather exposure, and the brand-name wicker path (most big-box wicker sets — Hampton Bay included — have documented dimensions). Measuring basics: how-to-measure.

What Sizes Do Wicker Cushions Come In?

Summary first: dining wicker chairs take standard-ish squares (19-21 inches), but wicker conversation sets run 23-27 inches of seat depth with tall back pillows — the territory where stock sizes stop working. Real documented examples from wicker series follow the table.

Those deep-seating numbers are not hypothetical — they are the documented range across wicker series in our Hampton Bay dimension database: Kampar wicker chaise seats run 31 x 50 inches and Oak Cliff chaises 24.5 x 48.5, Spring Haven chaises 23.5 x 50, and back pillows reach 7 inches of loft on Spring Haven loveseats and sofas (full chart).

Why Universal Cushions Fail on Wicker

Three geometric reasons, in order of how often they bite:

1. Seat depth. Universal deep-seating cushions top out around 22-23 inches of depth. Wicker conversation seats run 23-27. A shallow cushion on a deep deck leaves a hard gap behind your knees and walks backward constantly.
2. Back pillow loft. Wicker backs sit tall and reclined; they need real pillows (4-7 inches of loft) to bridge the frame angle. Universal back pads are flat by comparison — the “why does my back hurt” complaint.
3. One-piece benches and sectionals. Wicker loveseat benches (Edington’s 48-inch glider is the documented Hampton Bay example) and sectional wedges have no universal equivalent at all.

The Brand-Name Wicker Path

Most wicker conversation sets in American backyards are big-box brands, and the major one — Hampton Bay — now has a documented dimension database: 24 series of its own plus the 7 Martha Stewart collections sold beside it (195+ verified sizes across 31 collections). If your wicker set carries either brand:

1. Identify the series (model guide).
2. Look up the documented dimensions (Hampton Bay hub; worked examples: Spring Haven, Santa Rosa, Edington).
3. Order replacements cut to those exact OEM dimensions — no measuring needed for documented series.

Unbranded or import wicker skips straight to measuring and custom cushions — custom wicker cushions is the category page for that route, with the quick-drain construction open-weave seats need — tie layouts are a retrofit ( how to add ties to cushions ).

Fabric and Fill for Wicker

Wicker’s weave is ventilated — which means cushions on wicker get airflow from below (good for drying) but also debris, moisture, and insects through the weave (bad for fills that hold anything).

• – Fabric: solution-dyed acrylic or Olefin for anything living outdoors; wicker sets on covered porches can drop to polyester. UV hits wicker seating hard because the frames usually sit fully exposed.
• – Fill: foam-core or high-resilience foam over loose fiber — foam sheds water and dries through the weave; loose polyfill traps debris and moisture against the wicker.
• – Underside: a solid (non-grippy-cloth) base fabric resists the weave imprinting into the cushion and eases cleaning. Some workshops offer a mesh-bottom quick-drain option for uncovered sets — worth it where rain is frequent.

Measuring Wicker for Custom Cushions

Wicker-specific measuring notes beyond the standard method:

• – Seat depth: measure deck front to back, but subtract nothing for the weave — cushions sit on top of it. If the weave has a raised lip at the front, measure behind it.
• – Tapered seats: wicker seats often taper (wider at front). Measure both widths — this is the difference between a cushion that fits and one that bunches. Documented wicker examples: the Martha Stewart Miramar runs 25 front / 23 back; Palm Canyon firepit chairs 23/21.
• – Back height and angle: measure the back from seat deck to top rail, and note the recline — tall wicker backs sometimes want a two-part back solution (lumbar pad + headrest pillow) rather than one giant pillow.
• – Tie points: wicker frames offer natural tie-through gaps at the weave — note their positions and the weave gap size for tie placement.

Natural Rattan vs Synthetic Resin Wicker: Does It Change Cushions?

The two wickers diverge in ways that touch cushion choice:

• – Natural rattan/wicker (indoor and covered-porch furniture): the weave breathes and flexes; cushions live a gentler life. Cotton and indoor-outdoor blend covers are fine; foam grade matters more than fabric because the flexing frame abrades cushion undersides slowly. Natural wicker also dents under prolonged point pressure — dense foam distributes weight better than soft loose fill, which protects the weave itself.
• – Synthetic resin wicker (HDPE/PVC rattan) — what all outdoor wicker actually is, including every Hampton Bay wicker series: UV-stable, moisture-proof, and harder on cushions than natural fiber because it holds heat and water against the cushion underside. Quick-drain foam constructions and breathable base fabrics pay off here; a cushion with a sealed waterproof base on resin wicker traps condensation underneath and grows mildew at the contact face — the failure that gets blamed on “cheap cushions” when it is actually a construction mismatch.

The practical takeaway: on resin wicker, favor breathable over waterproof at the cushion base. Water passes through, dries through, and the frame does not care.

Caring for Wicker Cushions (and the Weave Beneath)

• – Vacuum the weave seasonally — debris that accumulates under the cushions grinds into both the weave and the cushion base with every sit.
• – Stand cushions on edge after rain, off the frame if possible: resin wicker holds a film of water that keeps cushion undersides damp for days otherwise.
• – Check tie points each spring — wicker’s natural tie-through gaps slowly enlarge as the weave relaxes with age; ties that once gripped can start sawing. Move ties to a fresh gap when the old one widens.
• – Store over winter — wicker frames can winter outside under covers, but the cushions should not; condensed moisture under a cover is worse than open-air exposure for cushion fill.
• – Wash covers per fabric tier: acrylic tolerates diluted bleach for mildew; Olefin prefers soap and water; polyester follows label instructions and fades either way. The fabric decision tree is in our Lowe’s guide.

Sourcing Summary: Three Routes for Wicker

• – Universal wall (covered in the Lowe’s and Home Depot guides): acceptable for wicker dining chairs in the 19-21 inch zone only; fails on conversation seating for the depth and loft reasons above.
• – Aftermarket spec catalogs: the brand-name path — the 31 documented collections across Hampton Bay and Martha Stewart make this the strongest aftermarket ecosystem in outdoor furniture (chart); other wicker brands vary from spotty to nonexistent.
• – Custom cutting: the universal fallback that always fits — measurements, trapezoid widths, and your choice of quick-drain construction for exposed sets: custom cushions.

For an unbranded wicker conversation set, the honest cost comparison: a full custom set (sofa + two chairs + ottoman in acrylic over HR foam) typically costs a fraction of replacing the furniture, and outlasts two rounds of the commodity cushions the set originally shipped with. Wicker frames — resin or natural — outlast everything; they are the best re-cushion investment in the furniture world.
