Key takeaways
- Measure the frame, not the old cushion: A compressed cushion reads shorter than it started. Run your tape along the seat platform from the top of the backrest to the front edge, then measure the width between the arm rails. Most standard loungers land at 72 x 21 inches, but 66-inch and 80-inch frames are common enough that guessing will cost you a return shipment.
- Count the fold sections: Loungers with adjustable backs need a cushion that hinges where the frame hinges. Two-section pads work on simple recliners; a 4-section design tracks contoured frames and zero-gravity chairs without bridging awkwardly across the bend.
- Read the fabric claim carefully: Water-repellent means beads roll off during a light shower. Waterproof usually indicates a backing or coating that blocks saturation. Double-sided treatment matters if you flip cushions to even out sun exposure, which is the cheapest way to double their lifespan.
- Check tie count and placement: Four ties is the minimum. Six is better on longer cushions, because wind lifts the unanchored midsection first. Ties should be stitched into the seam, not tacked on as an afterthought.
- Decide on fill before thickness: Polyester fiber fill at 3 inches feels plush initially and settles fastest. Memory foam at 4 inches holds its shape through repeated compression but takes longer to dry. Match the fill to how often the chair actually gets used.
What's inside
Anyone who has dragged a set of chaise lounges out of winter storage knows the drill: the frames are fine, but the cushions have gone flat, faded, and slightly crunchy from three summers of UV and sprinkler overspray. Replacing the whole lounger costs several hundred dollars. Replacing the cushion costs a fraction of that, and takes about four minutes with a pair of scissors and a tape measure. The hard part is not the swap, it is buying a cushion that actually fits the frame you already own and survives more than one season outdoors.
This guide comes from the perspective of someone who measures twice, checks seam construction before checking color, and has learned the hard way that “water resistant” and “waterproof” mean two very different things in a rainstorm. Below you will find the cushions worth considering in 2026, a breakdown of the specs that genuinely matter, and answers to the questions that come up once the old cushion is already in the trash bin.

The Best Chaise Lounge Cushions (2026) Reviewed
Summsun Chaise Lounge Cushions, Set of 2 (72 x 21 x 3, Teal)
The double-sided water-resistant treatment is the standout here, since most competitors coat only the top face and leave the underside to wick moisture off a damp deck. Buying as a set of two also keeps color batches consistent, which matters more than people expect once fading begins.
80 x 26 Inch Outdoor Chaise Lounge Cushions, Set of 2 (Cream)
Built for the oversized frames that standard 72-inch pads leave hanging short, with a 4-section design that follows contoured backrests cleanly. Six tie straps give it the best wind resistance in this group, and the removable cover means the cream color stays practical rather than aspirational.
Waterproof Chaise Lounge Cushions (72 x 21 x 3, Navy)
The tear-resistant fabric is the reason to look at this one, particularly for poolside chairs that get dragged across concrete rather than lifted. Navy hides pollen, sunscreen smudges, and general summer grime better than any light shade will.
Thickened Chaise Lounge Cushion (66 x 21 x 4)
A genuinely useful size for shorter apartment-balcony loungers and vintage frames that predate the 72-inch standard. The extra inch of loft makes it comfortable enough for indoor office or reading-chair duty in the off season.
MAGIC ELEPHANT Memory Foam Chaise Lounge Cushion (74 x 22 x 4, Oxford Blue)
Memory foam is the upgrade pick for loungers used daily, because it recovers from compression instead of developing a permanent body impression by August. Give it real drying time after rain, and store it under cover during the wet months.
Frequently Asked Questions
How do I measure for a replacement cushion?
Measure the seating surface of the frame itself, following the curve of the backrest with a flexible tape. Then measure the inside width at the narrowest point, usually between the armrests. Round down rather than up, since a cushion an inch short sits fine while one an inch wide bows in the middle.
Can I leave these cushions outside all season?
Water resistance handles rain, but continuous UV exposure and standing moisture will shorten the life of any outdoor cushion. Store them in a deck box or bring them under an eave when the forecast turns, and flip them monthly to distribute sun wear evenly.
How do I clean a chaise lounge cushion?
Unzip and machine wash the cover on cold, then air dry it fully before reinstalling. For the insert, spot clean with mild soap and a soft brush, and never put a foam core in a dryer.
Will a 3-inch cushion feel thick enough?
For casual poolside use, yes, especially over a sling or mesh frame that provides some give. For hard slatted wood or metal frames, or for anyone who naps out there regularly, step up to a 4-inch memory foam pad.
Final Thoughts
For most standard frames, the Summsun 72 x 21 set is the sensible default thanks to its double-sided water resistance and matched-pair pricing. Oversized loungers should go straight to the 80 x 26 four-section cushions for the fit and the six-strap anchoring, while anyone using their chaise daily will get more seasons out of the MAGIC ELEPHANT memory foam pad. Measure the frame first, and the rest is a five-minute job.
