Outdoor Cushions for Chairs 17x17 Waterproof Seat Cushions - Set of 2

In this review of the Outdoor Cushions for Chairs 17x17, the bottom line is simple: these cushions are aimed at anyone who wants a tidy, waterproof seat pad for patio or dining chairs without spending a lot. The single biggest reason to buy is the combination of a TPU double-layer waterproof surface and a solid 3 in 40D high-density foam core, which keeps the cushion dry and supportive for casual outdoor seating. The review covers fit, comfort, durability, and practical details like straps and a carry handle.

Key Features

• Precise size and fit: Each cushion measures 17in x 17in x 2.9in, making it a compact option that fits many patio, garden, and dining chairs when measured carefully.
• Non-slip fastening: Adjustable straps about 19.6in long secure the pad to chairs and help prevent slipping in breezy conditions or during activity.
• Waterproof surface: The 300GSM polyester with a TPU double-layer coating sheds water so the interior foam stays cleaner and drier after light rain or splashes.
• High-density foam core: Filled with a single block of 40D high-density foam roughly 3in thick, the cushion offers noticeable support and resists quick flattening.
• Practical handling and maintenance: A built-in handle and hidden zipper make the cushion easy to carry and remove for washing or airing.
• Vacuum packed with warranty: Items arrive compressed and may need 24-72 hours to recover; a 1 year warranty is included for buyer reassurance.

Who It's For

These cushions suit homeowners or renters who have standard-sized patio, rattan, or dining chairs and want a waterproof, supportive pad that is easy to move and maintain. They are particularly useful in humid or rainy climates where a water-resistant surface can prevent soggy seating and protect the foam core.

People who need oversized or extra-thick cushioning, or who require specialized outdoor upholstery finishes, should look elsewhere. Also measure your chair seating area first, because a number of users find the 17in square size too small for wider chairs.

Pros & Cons

Pros

• Waterproof TPU-coated fabric keeps the foam core drier than uncoated pads.
• Good initial comfort and support from the 40D high-density foam that holds shape well.
• Adjustable strap and handle make installation and handling straightforward.
• Vacuum packaging and a 1 year warranty provide convenience and some buyer protection.

Cons

• Size is compact at 17in x 17in, and several customers found the fit too small for some chairs.
• Vacuum packaging can cause creases and temporary flattening that take up to 72 hours to resolve.

Frequently Asked Questions

Will these cushions dry quickly after rain?
The TPU-coated surface repels water and helps the foam stay drier than uncoated cushions, but the foam itself is not advertised as quick-dry.

How long until the cushion expands after unpacking?
Allow 24-72 hours for the cushion to return to normal shape after vacuum packaging; gentle fluffing speeds recovery.

Can the covers be washed?
The cushions have a hidden zipper for removal; the handle and design suggest covers can be washed, but follow manufacturer care instructions for fabric and foam.
