Indoor Outdoor Waterproof Square Chair Cushion 18in x 18in - 2 Pack

Our review of these floral green square chair cushions finds them best for homeowners and renters who want an easy way to freshen patio, garden or office seating with dependable comfort and weather-ready fabric. The single biggest reason to buy is their combination of a removable, water resistant cover and a high density foam core that holds shape while offering supportive seating. The cushions arrive as a 2 pack in 18in x 18in x 2.5in size and are intended for standard dining and patio chairs where ties and a neat finish matter.

Key Features

• Premium material: High-quality polyester fabric paired with high density foam gives firm but comfortable support and resists quick deformation.
• Water resistant cover: The slipcover repels spills so water beads up and can be wiped away, helping protect the foam from light stains.
• Fade resistant: High UV piece-dyed fabric is rated for over 500 fade-proof hours so the floral green pattern stays brighter across seasons.
• Active ties: Attached ties secure cushions to chairs to prevent slipping during regular use on patio or indoor seating.
• Removable cover with invisible zipper: The wear-proof invisible zipper creates a tailored look and allows the cover to be removed for cleaning.

Who It's For

These cushions suit people who need an affordable, attractive upgrade for patio, lawn, deck or kitchen chairs and who value a cover that is easy to clean and resistant to sun fading. The 18in square size and 2.5in thickness fit standard chair seats and offer a firmer feel that many users prefer for everyday dining or outdoor conversation seating.

Those who need heavy-duty all-season cushions for long-term outdoor storage or deep seating for loungers should look elsewhere; this product is designed as a general-purpose seat cushion rather than a replacement for thick, weatherproof outdoor pillows intended for year-round exposure.

Pros & Cons

Pros

• Good build quality with high density foam that provides supportive, lasting comfort.
• Fabric is water resistant and stain resistant so light spills can be wiped away quickly.
• Active ties and an invisible zipper keep cushions secure and give a neat, tailored appearance.
• Vibrant floral green pattern is fade resistant for extended outdoor sun exposure.

Cons

• Some users may find the cushions firmer than plush alternatives; not ideal for deep lounge seating.
• A few reviewers reported faster fading in certain conditions, so heavy sun exposure may still affect long-term color retention.

Our Verdict

These 18in square cushions are a solid value for anyone wanting a neat, weather-aware upgrade to dining or patio chairs; the high density foam and water resistant, fade-resistant fabric deliver practical comfort and attractive appearance for typical outdoor use. Choose them when you need supportive seating and easy maintenance, but pick a thicker, heavier cushion if you want plush lounge comfort or year-round heavy exposure resistance.

Frequently Asked Questions

Can the cover be removed and washed?
The cover is removable via an invisible zipper and can be cleaned with a sponge or rag using mild soap and warm water, then air dried.

Are these cushions waterproof for outdoor use?
The covers are water resistant and stain resistant so spills bead up and can be wiped away, but the cushions are not described as fully waterproof for submersion or constant heavy rain.

Will the color fade in direct sunlight?
The fabric is piece-dyed with a high UV treatment rated for over 500 fade-proof hours, though very prolonged, intense sun exposure may still reduce vibrancy over time.
