Outdoor Chair Cushions Set of 2 17in x 17in x 3in - Thick Waterproof

Our review of these outdoor chair cushions finds them ideal for anyone looking to add comfortable, weather-resistant padding to 17in x 17in patio chairs. The single biggest reason to buy is the thick 3in double-layered foam core that delivers noticeable cushioning on hard seats while keeping its shape over time. The set of 2 arrives vacuum-sealed but recovers within days, and the vibrant color options make them an easy way to refresh a dining or patio seating area without replacing furniture.

Key Features

• Perfect fit for 17in chairs: Sized specifically for 17in x 17in seats so the cushions sit neatly on most standard patio dining chairs.
• Thick double-layered foam: The 3in high-quality foam core provides soft, elastic support that absorbs pressure and resists deformation during long sits.
• Waterproof and UV treated: Fabric resists water and fading for outdoor use, helping cushions hold color and repel stains when used on a patio or deck.
• Removable cover with hidden zipper: The zippered cover is easy to clean with a damp cloth and can be air-dried for low-maintenance care.
• Attached ties for stability: Four ties keep cushions securely fastened to chairs so they do not slide during use.
• Variety of colors: Vibrant tones complement outdoor decor and allow coordinated looks across seating sets.

Who It's For

These cushions are best for homeowners or renters who want an affordable comfort upgrade to 17in patio or dining chairs, especially those who already have a matching outdoor set and need replaceable, durable seat pads. They suit people who prefer a thicker foam feel than thin seat pads provide and want easy-care covers that can be spot cleaned.

Those who need fully machine-washable cushions, heavy all-season waterproofing for constant outdoor exposure, or custom sizing outside 17in x 17in should look elsewhere. Also, expect a short recovery period from vacuum packaging; the foam usually regains shape within about five days.
