Round cushions fit the circular seats of bistro chairs, metal cafe chairs and many wicker and iron chairs. Most are sold at about 15 inches across, so the seat diameter and how the ties reach the frame decide the fit.
We compared round outdoor cushions on diameter, thickness, fill, fabric, ties and grip, and cover care. If you also need the chairs, see Best Patio Bistro Sets with Cushions, or browse the Outdoor Cushions category.

How to Choose Round Outdoor Chair Cushions
Measure the Seat
Measure the seat across its widest point. A round pad slightly smaller than the seat looks neater than one that hangs over the edge.
Ties
Check where the ties sit and whether they can reach around your chair's back legs or spindles. Long ties help on thick wicker and iron frames.
Foam or Fiber
Foam pads stay flatter and firmer. Fiber and cotton fills feel softer and can be reversed, but they flatten with use.
Care
Removable, machine-washable covers make small cushions easy to keep clean. Store pads indoors or covered when you are not using the chairs.
How We Evaluate Round Outdoor Chair Cushions
For this guide we compared round outdoor cushions on diameter, thickness, fill, fabric, ties and grip, and cover care. We read each maker's specifications and noted where a listing leaves out the pack size or thickness. Most listings here had no rating data in our product feed, so ratings did not decide the order. We did not handle or measure these cushions ourselves, every figure comes from the maker's listing, and we never repeat a waterproof or fade claim as our own.
Variants of one listing count as a single product, and we would rather list a few strong picks than pad the list. Our full process is on the How We Review page.
FAQ
What size round cushion fits a bistro chair?
Summsun, Outsunny and Greendale all list a 15 inch diameter, but chairs vary. Measure your seat first.
Can round cushions stay outside?
Most makers recommend bringing them in during rain or storing them covered. Small cushions dry quickly in the sun.
Do round cushions work on square seats?
They will sit on a square seat but leave the corners bare. A square pad fits better.
Final Verdict
Summsun's pair is our top pick for its foam fill and washable cover. Outsunny is the best value set of 4, and Fitfree has the most secure grip.
Greendale is reversible, HOMELYSIAN is a tufted 4-pack, and idee-home has 4 ties per cushion. For square chair pads, see Best Patio Chair Cushions.
