YENING Outdoor Memory Foam Chair Cushions 20x20 Grey — 4" Extra Thick, Waterproof, Strap-Secured (Set of 2)

YENING's 4-inch memory foam outdoor chair cushions are waterproof, fade-resistant seat pads designed to add firm yet comfortable support to patio and deck chairs.

These square seat cushions combine a 1-inch memory foam layer over 3 inches of dense foam to deliver pressure-relieving comfort while keeping a resilient, supportive base. Built for outdoor use, the grey covers resist fading and repel water, and adjustable buckle straps secure each cushion to many furniture types. Choose from sizes ranging 19" to 25" to match your chair dimensions and enjoy a durable, easy-care seating upgrade for seasonal patios, balconies, or porches.

How do these cushions perform in outdoor conditions?

The cushions use waterproof cover layers to keep the interior foam protected from light rain and spills, and the fabric is treated to resist UV fading. When wet, the covers allow the cushions to dry naturally; for routine dirt or marks, the covers are machine-washable for simple maintenance.

• Waterproof outer layer shields foam from moisture and spills
• Fade-resistant fabric holds color under sunlight exposure
• Machine-washable covers for easy cleaning and upkeep

What kind of comfort and support do these 4-inch cushions offer?

A layered construction combines a 1-inch memory foam top for pressure distribution with a firmer 3-inch high-density foam core for stable support. The result is a seat pad that softens where you need it but returns to shape quickly, suitable for longer sitting sessions without collapsing.

• 1" memory foam layer reduces pressure on the hips and tailbone
• 3" dense foam core provides a stable, resilient base
• Extra-thick 4" profile supports heavier body types while maintaining comfort

Will these cushions fit my chairs and stay in place?

YENING offers multiple size options between 19x19 and 25x25 inches so you can match the pad to your chair seat measurements. Each cushion has an adjustable buckle strap that fastens around chair frames to prevent sliding and lift caused by wind.

• Available in sizes from 19" to 25" to match common patio chairs
• Adjustable buckle strap secures cushion to a variety of furniture styles
• Square shape adapts to dining, porch, and lounge chairs

How do I care for and maintain these cushions?

The covers are machine washable for regular cleaning; spot-cleaning with a damp cloth works for small spills or stains. Avoid prolonged saturation and allow cushions to dry fully before storage to preserve foam longevity and prevent mildew.

• Machine wash covers on gentle cycle; air dry to protect waterproof layers
• Spot-clean with mild soap and a damp cloth for quick cleanups
• Store cushions in a dry place when not in use to extend life
