deep cushions

Common seat sizes include 24" x 24" x 4", 22" x 24" x 6", and 24" x 24" x 6"; some listings show larger seat sizes (for example 36" x 38" x 6.5"). Back cushions are often listed at sizes such as 23" x 18" and 24" x 21".

Covers are commonly made from olefin, acrylic, polyester, or recycled polyester fabrics. Fills include generic 100% foam, high-density foam (often noted as 28D sponge or high-density resilient foam), and polyester fiberfill.

Many listings advertise water-related protection (waterproof, water-resistant, or all-weather) and UV- or fade-resistant treatments to help retain color. Descriptions sometimes clarify that cushions resist splashes but are not fully rainproof.

Most deep seat cushions use zipper closures and have removable, zippered covers. A smaller number are constructed with sewn seams and non-removable covers.

Care instructions most commonly recommend spot or wipe cleaning. Some listings advise hand washing removable covers (avoid machine washing) and recommend storing or covering cushions indoors when not in use.

Descriptions list high-density and high-resilience foams (including 28D sponge/high-density resilient foam) and polyester fiberfill. Many listings describe the cushions as thick, firm, and solid in feel.

Recovery times vary by product: some listings advise waiting around 2 hours or more, while others note cushions can take up to about 48 hours to fully spring back and fluff up.

Pack sizes range from single cushions to multi-packs. Listings commonly offer single-piece options and packs of 2, 3, 4, and even 6 cushions.

These cushions are designed for deep seats such as lounge chairs, chairs, loveseats, sofas, and patio furniture. They are marketed for both outdoor and indoor spaces including patios, balconies, decks, and lawns.

Many listings highlight sun/UV resistance and fade-resistant treatments to help cushions keep vibrant colors. Some specifically note olefin or UV-treated fabrics that resist fading for longer-lasting color.
