Which Patio Cushions Survive Sun, Rain and Mildew?
Arden Selections ProFoam deep seat sets dry fastest, because the open-cell core drains instead of storing rain. Honeycomb’s Sunbrella cushions hold colour longest on a shadeless deck. Classic Accessories Montlake FadeSafe adds a water-shedding backing, which suits climates where rain arrives weekly.
Arden Selections ProFoam deep seat cushions fit most patios that sit out in the weather, since water passes through the core rather than soaking into it. That one design choice heads off the sour smell that retires cushions by their second summer. Colour retention lags true solution-dyed acrylic, so an all-day sun exposure still points to a Sunbrella set.
Cushions go wrong on two fronts: fabric that fades in one season, and fill that behaves like a sponge. Fibre type, dye method and fill construction predict both outcomes. We compared fabric composition, published fade warranties, fill and foam construction, drainage design and standard seat dimensions, then read owner reports on mildew and colour loss after a full summer outdoors.
Our top picks
Arden Selections ProFoam Deep Seat Patio Cushion Set
Open-cell ProFoam lets rainwater pass through the core instead of holding it, so a soaked set is usable by the next afternoon. Olefin covers unzip for washing, and the 24 by 24 inch seat matches most big-box wicker frames. Firmness sits above a fibre-filled cushion, which suits anyone who dislikes sinking into a seat.
Pros
- Water exits the core instead of pooling inside it
- Zippered covers wash without unpacking the foam
- Standard 24 inch seat fits common conversation frames
Cons
- Olefin dulls faster than solution-dyed acrylic in full sun
- Open-cell core feels firmer than a polyester fill
Honeycomb Indoor/Outdoor Sunbrella Deep Seat Cushion Set
Sunbrella acrylic carries pigment inside each fibre, so sunlight abrades the surface without lifting the shade. Welted seams and sewn-in ties hold shape on slatted frames across several seasons. Diluted bleach is safe on this fabric, which turns a mildew spot into a cleaning job rather than a replacement.
Pros
- Solution-dyed fibre outlasts any printed fabric in sun
- Diluted bleach lifts mildew without stripping the colour
- Welted edges resist the sagging that flat seams show
Cons
- Polyester-wrapped foam holds water longer than open-cell
- Air drying a soaked cushion takes close to a day
Classic Accessories Montlake FadeSafe Patio Chair Cushion
FadeSafe polyester is solution dyed and backed with a water-shedding treatment, so rain beads off before the fill can wick it in. Sizing spans dining seats, high back chairs and bench pieces, which lets a mismatched patio read as one set. Colours run to muted solids, without the prints that olefin lines offer.
Pros
- Written fade warranty stands behind the colour claim
- Treated backing keeps rain out of the fill
- One colour spans chair, bench and high back cuts
Cons
- Palette stops at solids and a few stripes
- Fill flattens under daily seating within a season or two
Pillow Perfect Outdoor/Indoor Deep Seat Cushion Set
Polyester fibre fill gives a plusher seat than any foam core here, and the print range runs from florals to stripes to solids. Covers are sewn closed, so cleaning stops at spot treatment and a hose rinse. Roofed porches suit it well; sprinklers and standing water do not.
Pros
- Largest pattern and colourway choice in this group
- Fibre fill compresses softly instead of pushing back
- Seat and back pieces arrive matched as a pair
Cons
- Fibre fill absorbs rain and dries over days
- Sewn-closed covers rule out machine washing
LVTXIII Outdoor Deep Seat Cushion Set
Neutral olefin solids in beige, grey and navy read well against rattan and wicker. Sewn-in ties anchor the back cushion, fixing the forward creep that budget sets are known for. Plan on replacement every few seasons, since the repellent finish is a coating rather than a fibre property.
Pros
- Muted solids blend with wicker and rattan frames
- Back ties stop the cushion sliding into the seat gap
- Light weight makes carrying a set indoors quick
Cons
- Repellent finish washes out after several cleanings
- Seam stitching frays earlier than higher-tier sets
Greendale Home Fashions Outdoor Chaise Lounger Cushion
At roughly 72 inches, this hinged pad covers the lounger length most cushion ranges skip entirely. Overstuffed polyester bridges slat gaps on metal and wood frames, while the hinge folds where the backrest lifts. Winter storage needs a plan, because a 6 foot cushion will not fit a small deck box.
Pros
- Sized for full-length chaise frames other lines ignore
- Hinge tracks the backrest without bunching at the fold
- Thick fill hides the ridges of a slatted frame
Cons
- Six feet of cushion is awkward to store off season
- Deep fill stays damp long after rain stops
Sunnydaze Olefin Indoor/Outdoor Seat Cushion
Two inches of thickness keeps proportions right on a bistro or dining chair, where a deep seat pad would swamp the frame. Corner ties knot to tube metal and wooden spindles alike. Comfort tops out after about an hour on a hard metal seat, so treat this as a pad rather than a lounge cushion.
Pros
- Slim profile suits cafe and bistro chair frames
- Stacks flat in a deck box over winter
- Corner ties fit tube metal and wood uprights
Cons
- Two inches is thin for long meals on metal seats
- No matching back pad sold in the range

Before you buy
What to look for in outdoor cushions Dye method predicts fade resistance more reliably than fibre name. Solution-dyed acrylic and FadeSafe polyester carry pigment inside the fibre, so sun wears the surface and leaves the shade behind. Printed polyester loses colour first, usually along the front edge that catches afternoon light. Olefin lands between the two: cheap, strongly mildew resistant, yet visibly dull after two summers facing south. Three details on a listing settle most decisions, namely fibre and dye type, fill construction, and whether covers unzip.
Fill types and why drainage decides lifespan Closed foam and polyester fibre both absorb rain, and mildew starts inside a cushion that still looks clean. Open-cell cores such as Arden’s ProFoam pass water straight through and dry in hours. Fibre fill feels softer and belongs on a roofed porch, away from sprinklers and coastal fog. Thickness compounds the problem, since a 6 inch deep seat traps far more water than a 2 inch dining pad. Stored damp in a closed deck box, any fill will smell by spring.
Measuring for deep seat, dining and chaise frames Most deep seat sets follow a 24 by 24 inch seat with a 21 inch back, which covers mainstream wicker conversation frames. Measure the frame’s inside seat area rather than the old cushion, because years of use have already compressed it. Dining chairs take a pad near 19 inches square at 2 to 3 inches thick. Chaise frames need a hinged piece close to 72 inches, a length few ranges stock. Placement counts as much as size: ties should land at the back uprights, or the cushion walks forward each time someone stands.
Sun-baked decks versus covered porches Exposure decides how much fabric quality is worth buying. On a south or west-facing deck with no shade, solution-dyed acrylic is the only fibre that holds colour past a few years. Under a roof or pergola, printed polyester lasts fine and the pattern range opens right up. Skip Sunbrella if cushions live in a garage nine months a year, since storage habits shape lifespan more than fibre does. Rinse pollen and salt off monthly, and rotate cushions end to end so one edge does not absorb every afternoon of sun.
Frequently asked questions
What is the best fabric for outdoor cushions?
Solution-dyed acrylic such as Sunbrella holds colour longest in direct sun. Olefin is the value alternative with strong mildew resistance. Printed polyester looks good at first and fades early, usually along the front edge.
Can outdoor cushions be left out in the rain?
Occasionally, provided the fill drains. Open-cell foam sets dry within hours, while polyester fibre can stay damp for days and turn sour. Repeated soaking shortens any cushion’s life, so bring sets in for long wet spells.
What size cushions fit a standard patio chair?
Deep seat conversation sets usually take a 24 by 24 inch seat with a 21 inch back. Dining chairs take pads near 19 inches square. Measure the frame’s inside seat width and depth instead of copying a flattened old cushion.
Sunbrella vs olefin: which is worth buying?
Sunbrella wins on fade resistance and tolerates diluted bleach. Olefin resists mildew well and suits shaded or covered patios. Full afternoon sun is the single condition that justifies stepping up to acrylic.
How do you get mildew off patio cushions?
Scrub with mild soap and water using a soft brush, rinse thoroughly, then dry completely in the sun. Sunbrella acrylic accepts a diluted bleach solution, which most polyester and olefin fabrics do not.
Do patio cushions need ties?
On sloped or slatted frames, yes. Ties keep a back cushion from sliding into the seat gap whenever someone gets up. Deep seat sets on flat bases generally stay put without them.
How long do outdoor cushions last?
Owners report roughly two to three seasons from budget polyester sets and five or more from solution-dyed acrylic, assuming off-season storage. Leaving cushions outside year round cuts those figures about in half.
Are outdoor cushion covers machine washable?
Only zippered covers, and only where the label allows it. Wash cold, skip the dryer, and refit covers slightly damp so they stretch back to shape. Sewn-closed sets like Pillow Perfect are spot clean only.
Which outdoor cushions work best on a shaded porch?
Shade removes fade pressure, so pattern and comfort can lead the choice. Pillow Perfect fibre-filled sets make sense there. Keep an eye on humidity, because a fibre fill still dries slowly in still air.
The bottom line
Arden Selections ProFoam sets are the practical buy for an uncovered patio, because drainage stops the mildew that kills cushions well before fabric gives out. Honeycomb’s Sunbrella sets earn their place on a shadeless southern deck, where colour loss shows up first. Pattern hunters with a roofed porch should take Pillow Perfect and accept the slower drying that fibre fill brings.
