Great look, great quality
Loved that they arrived overnight! The pattern is so colorful and cheerful...just makes me happy. The price was much lower than anything comparable online, and the quality seems excellent. Cushions were even thicker than anticipated. This was a great purchase.

Porch Perfect: Budget-Friendly Cushion
If you're lookin' to add a little comfort and charm to your porch sittin', this Mainstays tan outdoor seat pad is just the ticket. The warm, neutral color blends right in with a classic Southern palette, whether you're rockin' white wicker or a weathered wood bench. It's got just the right amount of cushion—not too thick, not too thin—and it holds up well even on those long, sunny afternoons. The ties keep it from slidin' around when the kids hop up, and it's easy to wipe down after a sweet tea spill. Simple, affordable, and made for front porch livin'.

I Specifically Wanted
I specifically wanted this design pattern. I wanted these chair cushions back in 2024 and were out of stock. I searched again this year and thankfully they were available. Happy camper! They are constructed well and are perfect to place inside my outdoor black metal chairs for my front porch.
