Summsun D-Shape Outdoor Chair Cushions, 17 x 16 Inch, Dark Gray, Set of 4

If you’re furnishing several patio seats, a coordinated set can make it easier to give them a consistent look, for a single chair, matching the cushion’s shape and measurements to the seat matters most. These Summsun D-shaped cushions come as a set of four, with a dark gray polyester cover and foam filling for outdoor seating.

Each cushion measures 17 x 16 inches and is 2 inches thick. Ties help keep it in place, while the removable, machine-washable cover makes routine care straightforward.

Technical overview

The curved D-shape is designed for outdoor chairs and patio furniture, including garden, porch, barrel, wicker, and bistro-style seats. Measure the seat before choosing a cushion so you can compare its dimensions and outline with the chair.

• Shape: D-shaped
• Size: 17 x 16 inches
• Thickness: 2 inches

• Cover: 250gsm polyester, removable and machine washable

The foam’s high-rebound construction is intended to provide support during seated use, while the polyester cover is made for outdoor conditions. Piped edges and reinforced stitching add definition to the cushion’s shape. The ties offer a practical way to secure each pad to a chair and help limit shifting as people sit down or get up.

Best use cases

These cushions suit patio dining chairs, porch seating, garden chairs, and other outdoor seats with a compatible D-shaped surface. For example, placing a set across the chairs around a patio table creates a coordinated seating area, and the dark gray color works as a neutral choice alongside different outdoor furniture finishes. The four-piece format is particularly useful when you want to update several seats at once rather than choose pads one by one.

The fabric’s water- and fade-resistant properties are useful for outdoor seating exposed to changing conditions. For everyday upkeep, unzip and remove the cover for machine washing, then return it to the cushion once clean and dry. Customer feedback often highlights comfort, appearance, fit, and water resistance, comments on tie durability are mixed, so fastening them with care is a sensible part of regular use.

What you get

The set contains four D-shaped chair cushions, each with foam filling and a removable cover. Each cushion has two ties for attaching it to the chair. The cushions are shipped compressed, so they may need time to recover their shape after unpacking, allow 1–3 days for expansion. Gently shaking or fluffing them can help during this process.

Should you buy it?

It makes sense if you’re replacing or coordinating cushions across several outdoor chairs and want a defined size, curved shape, and washable covers in one set. Compared with selecting a cushion for just one seat, this four-piece set is designed to outfit multiple chairs with a consistent dark gray finish. Its 17 x 16-inch footprint, 2-inch foam filling, and tie attachments make it a practical fit for suitable patio and porch seating.
