What to check before you buy
Fill & Structure
The upgraded density keeps them from going flat halfway through summer. Tight stitching locks the fill in place so you're not fluffing every weekend. You get actual support and softness at once—no plastic-bag feel.
Water Resistance
Splashes and morning dew won't penetrate. The liner is your first line of defense against mold and rot. It's not fully waterproof, but it's engineered for the wet reality of patio life, not a pool.
Fit & Prep
They arrive compressed. Unpack and gently tap to fluff—takes a few minutes. Standard patio pillow-cover size, so no guessing on fit.

Where this sits
