Key takeaways
- Measure the deck, not the chair: Run your tape along the sitting surface from headrest top to footrest end, following the contour rather than the straight line. Then measure width at the narrowest point. Buy within an inch either direction — long is more forgivable than short.
- Match hinge sections to your frame’s bends: Adjustable chaises articulate at the back and sometimes the knee. A 4-section cushion folds cleanly over both breaks; a single-slab pad will bridge and gap, creating a pressure ridge right under your shoulder blades.
- Read the fabric claim carefully: “Water resistant” means rain beads and rolls; “waterproof” usually means a coated backing that blocks soak-through. Neither survives being left out all season. Fade resistance comes from solution-dyed fiber, which holds color far longer than surface-printed polyester.
- Count the ties and check placement: Two ties at the head only means the foot end slides every time you sit down. Six straps distributed across the length is the standard worth targeting, and loops beat knots for repeated seasonal removal.
- Decide on foam versus fiberfill: Polyester fiberfill is lighter, dries faster, and compresses over one to two seasons. Memory foam holds shape and supports better but retains moisture, so pair it with a removable cover you can actually pull off and hang dry.
What's inside
Anyone who has dragged a set of lounge chairs out of winter storage knows the drill: the frames are fine, but the cushions have gone chalky, thin, and vaguely swamp-scented. Replacing the whole chair feels wasteful when the aluminum or resin wicker underneath still has a decade left in it. The catch is that chaise cushions are dimensionally fussy — a 72-inch pad on a 78-inch frame leaves your calves hanging over bare slats, and a 3-inch pad on a deep-welled sling chair swallows itself.
I measure my own frames before every replacement purchase, and I have learned to care as much about the tie straps and cover zippers as the foam itself. This guide walks through six current replacement chaise cushions across the common size classes — 71 to 80 inches long, 21 to 26 inches wide, and 3 to nearly 5 inches thick — with notes on fabric behavior, folding hinge design, and which ones actually stay put when you shift your weight. Bring a tape measure to this one.

The Best Chaise Lounge Cushions (2026)s Reviewed
Summsun Chaise Lounge Cushions, 72 x 21 x 3, Teal
This is the sensible default for standard-frame chaises, and the double-sided construction is the detail that earns it: flip the pad at midseason and you effectively double the life of the surface facing the sun. At 3 inches it reads firm rather than plush, which suits sling and slat frames that already have some give.
80 x 26 Inch Chaise Lounge Cushions, Cream
The size class most manufacturers ignore — oversized commercial-style loungers and wide teak frames — and the 4-section fold handles both the back and knee articulation without bunching. Six tie straps keep the extra footprint anchored, though cream will show pool-deck grit, so plan on periodic cover washing.
Crestlive Foldable Chaise Lounge Cushions with Headrest, 71 x 21
The integrated headrest bolster is the standout here, saving you from balancing a separate pillow that inevitably slides into the gutter. Genuinely light enough to carry two at a time when a storm rolls in, which matters more than spec sheets suggest.
AAAAAcessories Chaise Lounge Cushions, 72 x 21 x 3, Navy Blue
A straightforward workhorse in the most forgiving color for outdoor use — navy hides sunscreen smudges and organic staining better than any light neutral. The waterproof backing means a passing shower will not leave you with a saturated core, though I still tilt these upright to drain.
Thickened Chaise Lounge Cushion, 71 x 22 x 4.7, Cream
At nearly 5 inches this is the comfort pick, and the non-slip underside is doing real work on smooth resin and powder-coated frames where fabric-on-fabric normally creeps. Best on flat-deck chaises rather than deeply contoured ones, since the loft resists tight bends.
Frequently Asked Questions
How do I measure for a replacement chaise cushion?
Lay your tape along the seating surface following its curve, from the top of the headrest section to the end of the leg rest, then measure width at the tightest point between armrests or frame rails. Note where the frame hinges fall so you can match section counts.
Can these cushions stay outside year-round?
No replacement cushion in this category is built for permanent exposure. Water-resistant and waterproof fabrics buy you time against rain and dew, but continuous UV and freeze cycles will break down both fabric and fill. Store them in a deck box or bring them in.
Are memory foam cushions worth it outdoors?
They hold their shape far longer than fiberfill and feel notably better on long afternoons — the MAGIC ELEPHANT memory foam pad is a good example. The tradeoff is slower drying, so treat the removable cover as essential maintenance equipment.
Will these fit my specific chaise brand?
Fit is dimensional, not brand-based. A 72 x 21 pad works on any frame with roughly those measurements regardless of manufacturer. Trouble comes from deeply sculpted or unusually narrow frames, where a slightly undersized cushion beats an oversized one that buckles at the edges.
Final Thoughts
For most standard chaises, the Summsun 72 x 21 set is the pick I would order without much deliberation — flippable, correctly sized, and priced for buying in pairs. Oversized frames should go straight to the 80 x 26 cream set for its four-section fold and six-strap anchoring, while anyone prioritizing comfort over quick drying will be happiest with the MAGIC ELEPHANT memory foam pad and its 4-inch loft.
