Replacement cushions for outdoor furniture

Measure the seat platform of the frame you already own — width, depth and the cushion thickness you want — then buy by fabric type, because solution-dyed acrylic holds color for years where printed polyester fades in two seasons. Replacing cushions on a sound frame is almost always better value than replacing the furniture.

Replacing beats replacing the furniture

Cushions are the shortest-lived component of most patio furniture by a wide margin. Printed polyester cushions realistically give two to four years before visible fade, while the aluminum or poly frame under them is a fifteen- to twenty-year product. That mismatch is why so much structurally sound furniture gets replaced: the set looks tired, and the tired part is the fabric.

This page is about buying for a frame you already have. If you are choosing cushions as part of a new purchase, or comparing fabrics on their merits, our cushion roundup is the page for that.

How to measure the frame you own

Measure the furniture, not the old cushion. A compressed, sagging cushion is smaller than the space it was made for, and a cushion that was always slightly wrong will reproduce the same mistake.

The method is the mirror image of measuring for a cover, where you measure the outside of the furniture rather than the inside. If you are doing both jobs, the cover measuring guide sets out that side.

Standard sizes, and when you are outside them

Most mass-market outdoor furniture is built around a handful of standard cushion footprints, which is the single most useful thing about this category: it means off-the-shelf replacements genuinely fit a lot of frames. Deep-seat sets in particular cluster tightly, and standard sizing is why the mainstream cushion lines exist at all.

You are likely outside the standard range if:

• The furniture was sold as a complete set by a single brand with its own cushion dimensions, especially premium wicker.
• The frame is custom or Amish-built. Small-batch makers use their own platform sizes.
• The seat is an unusual shape — a curved sectional corner, a trapezoidal wedge, a rounded chaise end.

In those cases the options narrow to the original manufacturer, a custom cushion maker, or re-covering the existing foam. Re-covering is the cheapest route if the foam is still sound, and the only one that keeps an exact fit.

What to look for in the fabric

One question answers most of this: did the color go into the fiber, or onto it?

• Solution-dyed acrylic has pigment added to the liquid polymer before the fiber is spun, so color runs through the strand. Sunbrella publishes five years of coverage on upholstery and sling lines and ten years on shade and marine lines — the strongest published commitment in outdoor fabric — and it tolerates cleaning with a diluted bleach solution without losing color.
• Printed or surface-dyed polyester is colored on the outside. It is cheaper by a multiple, and it fades visibly in a couple of seasons of full sun.
• "Fade-resistant" is not the same claim as solution-dyed. It is a comparative word with no published standard behind it.

A faded cushion cannot be restored, because the dye molecules themselves have broken down — which is why our restoration guide ends at replacement for fabric while offering real fixes for wood and metal.

Fill, and the part no warranty covers

Read the fabric warranty carefully: it covers the fabric. Not the foam, not the stitching, not the zips. Those three are what actually end most cushions, and they are rarely specified in a listing at all.

• Quick-dry reticulated foam lets water pass straight through and is the right fill for furniture that stays outside. Standard polyester fill holds water and stays damp in the middle.
• Removable zippered covers are worth insisting on. They let you wash the cover and dry the fill separately, and they make the cushion repairable.
• Ties or straps keep cushions on the furniture in wind. Without them, cushions end up in the garden, which is also how they get dirty enough to need washing.

Before buying a replacement set it is worth knowing what you should expect from it: how long outdoor cushions last separates the fabric clock from the fill clock.
