Wellsin Outdoor Chair Cushions for Patio Chairs, Set of 4 18.5x16x3 Forest Green — Water‑Resistant, UV‑Stable High‑Density Foam

Wellsin Outdoor Chair Cushions are a set of four water-resistant, UV-stable 18.5" x 16" x 3" seat cushions designed to add comfort and lasting color to standard patio chairs.

If you want to upgrade hard outdoor seating into comfortable, weather-ready chairs without reupholstering or buying new furniture, this Wellsin set gives you thick, non-slip padding in a classic forest green. Each cushion has secure corner straps, high-density foam for sit-down support, and solution-dyed polyester that resists fading and moisture. They’re sized for most standard chair seats and made to perform on patios, balconies, decks, and indoor dining areas where durable, attractive cushioning is needed.

How do these cushions stay in place during regular outdoor use?

Each cushion includes two sewn straps on opposite sides that fasten to the back of the chair to reduce slipping and shifting. The strap placement keeps the cushion aligned when you sit down or stand up, cutting down on constant readjustment.

• Two straps per cushion for secure fastening
• Sewn-in design prevents strap detachment
• Square-corner fit suits standard chair frames

What level of comfort and support can I expect from the 3" thickness?

The cushions use high-density foam that provides firm yet forgiving support to reduce pressure on the seat during extended sitting. The 3-inch thickness is balanced to offer cushioning without changing the chair’s ergonomics or making it unstable.

• 3" high-density sponge core for reliable support
• Firm enough for dining or conversation seating
• Retains shape for frequent, everyday use

Will the color hold up to sun and rain on my patio?

The covers are made from solution-dyed polyester engineered for three-year color fastness, which helps the forest green resist fading from sunlight. The fabric also sheds light moisture and is easy to clean with a damp cloth—ideal for covered patios and mild outdoor exposure.

• Solution-dyed polyester for extended UV resistance
• Water-resistant surface for light spills and dew
• Wipe-clean maintenance keeps cushions looking fresh

What chair types and settings are these cushions best suited for?

With measurements of 18.5" W x 16" D x 3" H, these cushions fit most standard dining and patio chairs—check your seat dimensions before buying. Their durable cover and neutral forest green color make them appropriate for outdoor patios, balconies, garden seating, or indoor dining areas where you want a quick comfort upgrade.

• Designed for standard-sized patio and dining chairs
• Set of four cushions for matching seating groups
