Wellsin Outdoor Chair Cushions for Patio Furniture - Set of 4 Yellow, 18.5"×16"×3", Waterproof & UV-Resistant

Wellsin Outdoor Chair Cushions are a four-piece set of waterproof, UV-resistant seat pads that add 3 inches of supportive foam comfort to your patio or indoor chairs.

These patio chair cushions combine a full-piece high-rebound sponge core with a tightly woven polyester cover engineered to resist sun, rain, and everyday wear. Sized at 18.5" × 16" × 3", the set of four fits most standard dining and patio chairs and includes sewn-in straps so cushions stay put through frequent use. Low maintenance and quick to wipe clean, they refresh hard seating into a comfortable place to sit without bulky installation or replacements.

How comfortable are these cushions for long outdoor gatherings?

The cushions use a single-piece 3" thick high-density foam that balances plushness with support, relieving pressure points during longer sits. The foam resists quick deformation and has good rebound, so it keeps shape after repeated use.

• 3-inch continuous high-density sponge core for steady support
• High-rebound foam to reduce sagging over time
• Designed to reduce pressure on hips and lower back

Will they stand up to sun and occasional rain?

The outer shell is made from durable polyester fabric treated for UV and water resistance, helping colors stay vivid and preventing light moisture absorption. Routine maintenance is simple—wipe with a damp cloth and air dry—so these cushions are practical for patios, balconies, and covered outdoor spaces.

• UV-resistant polyester minimizes fading in sunlight
• Waterproof surface repels light rain and spills
• Wipe-clean fabric for low-effort upkeep

How do these cushions stay in place on different chairs?

Each cushion includes two stitched straps on the sides to secure the pad to the chair back or frame, reducing slipping and the need for constant readjustment. The ties are built to handle regular movement so you can relax without correcting misaligned cushions.

• Two attached side straps per cushion for stable placement
• Sewing and strap position optimized for common chair styles
• Works with both outdoor and indoor seating arrangements

What size chairs are these cushions best for and how many come in a set?

This package contains four square-corner cushions sized 18.5" wide, 16" deep, and 3" thick—compatible with many dining, bistro, and patio chair designs. To ensure the best fit, measure your chair seat dimensions before ordering and compare to the listed measurements.

• Set of 4 cushions for coordinated seating
