Basic Beyond Outdoor Chair Cushions Set of 4 — Yellow 18.5x16x3, Water-Resistant Polyester with 2 Ties

These are a set of four water-resistant, square-corner outdoor chair cushions (18.5" x 16" x 3") with dual straps for stable seating and fade-resistant polyester covers.

Upgrade your patio seating with Basic Beyond's Outdoor Chair Cushions set of 4. Each cushion is designed to fit most standard dining and patio chairs with a compact 18.5" x 16" seat and 3" thickness. The cushions combine a resilient foam core with a durable polyester exterior engineered to resist water and fading, while two fastening ties on each cushion help keep them securely in place during everyday use.

Will these cushions fit my patio or dining chairs?

The cushions are square-cornered and sized to suit most standard chairs used for patios, decks, and dining sets. Their compact footprint makes them a good match for metal, wood, and wicker frames. If your chair has an unusually deep or narrow seat, measure first to confirm fit.

• Seat dimensions: 18.5" (front to back) x 16" (side to side) x 3" thick.
• Square-corner shape fits standard flat seats and slatted chairs.
• Two straps per cushion secure them to chair backs or rails.

How do these cushions hold up outdoors and in wet weather?

Basic Beyond cushions use a 100% polyester cover that resists fading and sheds light moisture, while the interior foam is resilient for regular seating. They are water-resistant rather than fully waterproof, so they withstand splashes and short exposure but should be stored indoors or kept under cover in heavy rain.

• Polyester fabric: fade-resistant and quick-drying for outdoor use.
• High-quality sponge core with good resilience for lasting shape.
• Recommended to store or cover during prolonged wet weather.

How do I keep these cushions clean and crease-free after unpacking?

The cushions arrive vacuum-packed for compact shipping and may show creases on opening; allow 24–48 hours for the foam and cover to recover to normal shape when laid flat. For everyday care, spot clean with a damp cloth and air dry—no special detergents required.

• Unpack and lay flat for 24–48 hours to return to full thickness.
• Spot clean with mild soap and a damp cloth; hang to dry.
• Do not machine wash the inner foam; keep away from prolonged direct heat.

How do the straps help and are they easy to use?

Each cushion includes two sewn-in ties that fasten to chair frames to prevent slipping and frequent readjustment. The ties are simple to loop and knot, keeping cushions aligned during meals and social gatherings without interfering with chair movement.

• Two straps per cushion—secure to back slats or side rails.
• Keeps cushions from sliding during normal use and movement.
• Straps sit flat and won’t add bulk under the seat.

Who is this for: These Basic Beyond cushions are geared to homeowners, renters, and outdoor entertainers who want comfortable, low-maintenance seating for patios, porches, balconies, and dining sets. They suit people seeking compact, color-forward cushions that balance everyday weather resistance with simple care. Choose this set if you want an easy way to add consistent padding and bright color to multiple chairs without large, bulky cushions.
