Unimatta Square Corner Seat Cushions are a set of four 19" x 19" x 3" water-repellent, high-density foam chair pads designed for indoor and outdoor seating with secure ties and removable covers.

These square seat cushions are made for everyday patio, deck, garden, and dining chairs, balancing durable outdoor performance with simple home-care. The covers are crafted from eco-conscious polyester treated to resist water, UV fading, and stains, while the inner 100% high-resilience foam restores comfort quickly after unpacking. Each cushion includes ties to keep it positioned on the chair and piped edges for extra durability and a finished look.

Will these cushions fit my patio and dining chairs?

Measure the seating area of your chair before purchasing — the Unimatta cushions are 19 inches wide by 19 inches deep and 3 inches thick, a size that suits most standard outdoor and indoor chairs. Their square shape works especially well on armless chairs, metal bistro chairs, and many wooden dining seats.

• Dimensions: 19" W x 19" D x 3" T — fits most standard chairs
• Square profile complements armless and cornered seats
• Set of four covers an entire dining table or patio set

How do these cushions hold up outdoors and how do I clean them?

The outer fabric is a sturdy polyester blend treated for water repellency and UV resistance, so it sheds light moisture and resists fading from sun exposure. The cover is removable with a covered YKK zipper for quick spot cleaning or full washing; the foam insert can be ventilated to air out but should be kept dry for longevity.

• Water-repellent polyester with UV protection resists fading
• Covered YKK zipper allows easy removal and washing of the cover
• Air-dry foam and keep from prolonged wet exposure to preserve shape

Do the cushions stay in place and how comfortable are they?

Each cushion includes two non-slip ties that secure to chair slats or frames to prevent sliding during use. The interior is filled with high-density, high-resilience 100% foam that provides firm support while cushioning pressure for comfortable sitting over meals or long conversations.

• Two ties per cushion keep pads anchored to the chair
• High-density foam offers stable support and durability
• Piped edges strengthen seams and maintain shape

What should I expect right out of the package?

The cushions are shipped vacuum-sealed to save space and protect the fabric. After opening, allow up to five days for the foam to fully expand and return to its original thickness; gentle fluffing and a few hours in a well-ventilated area will speed recovery.

• Arrive vacuum-compressed — expands within about five days
• Fluff and air out covers for best comfort and scent removal
• Follow care instructions on the label to maintain water repellency

Who is this for? These Unimatta square seat cushions suit homeowners and renters who want an affordable upgrade to their outdoor dining, patio, or garden seating without complicated installation. They’re ideal for people who need a balanced mix of weather resistance, supportive comfort, and easy maintenance for seasonal outdoor living or everyday indoor use.
