Zonamat High Back Patio Chair Cushion 21x44 Navy Blue — Waterproof, Fade-Resistant Outdoor Seat & Back Pad

These cushions combine a high-density foam core with solution-dyed, 280 GSM fabric and a double-sided waterproof barrier to withstand outdoor conditions while retaining color and shape. Sized to accommodate a 21"W seat and a 24"H back, the cushions have removable, machine-washable covers and integrated straps so they stay put on gliders, lawn chairs, and dining chairs. They’re made to simplify care and extend the life of your outdoor seating without sacrificing comfort.

How do these cushions handle spills, sun, and weather?

The cushions use a double-sided waterproof barrier and solution-dyed fabric to resist liquid penetration and UV fading. That combination reduces the chance of mildew and prevents color washout from sun exposure.

• Double-sided waterproof membrane blocks moisture from reaching the foam.
• 280 GSM solution-dyed fabric resists fading and stands up to UV rays.
• Quick-drying materials and removable covers simplify cleanup after spills.

Will they fit my high-back patio or dining chair?

Measure before ordering: the full cushion is 21" wide, 44" long and 2" thick (seat: 21" x 20"; back: 21" x 24"). This shape suits most high-back patio chairs, gliders, and many dining chairs with a tall back. The integrated straps help adapt the cushion to slightly different chair frames.

• Overall dimensions: 21"W x 44"L x 2"T for a combined seat and back profile.
• Seat area: 21"W x 20"D — fits standard dining chair seats.
• Back area: 21"W x 24"H — supports taller chair backs and gliders.
• Adjustable straps secure the cushion to different chair shapes.

How do I clean and maintain these cushions?

The covers unzip quickly with smooth metal zippers and are machine washable for periodic cleaning; for daily maintenance, wipe with a damp sponge and air dry. The easy-care design keeps cushions fresh without specialized treatments.

• Easy-glide metal zippers allow fast cover removal for machine wash.
• Spot clean with a damp sponge for routine upkeep.
• Air-dry covers to preserve fabric and waterproof barrier performance.

What kind of comfort and support do they provide?

High-density foam offers a moderately firm feel with good rebound, balancing support and comfort for prolonged sitting. A smooth protective lining inside increases durability and helps the cushion retain its shape over time.

• Moderately firm high-density foam maintains support and shape.
• Quick rebound reduces flattening under regular use.
• Protective inner lining extends foam longevity and resists wear.

Who is this for: These Zonamat cushions suit homeowners and renters who want reliable, low-maintenance outdoor seating for patios, porches, decks, and garden areas. They’re a practical choice for anyone needing a high-back cushion that fits standard dining and glider chairs, resists weather and UV damage, and allows fast cleaning—ideal for families, hosts, and anyone wanting comfortable, durable outdoor seating in navy blue.
