HOMBYS 22x22x6 Replacement Couch Cushion Insert — High-Density Foam with Removable Washable Cover

If your sofa feels flat, the HOMBYS cushion insert brings back support and shape without reupholstering. This 22" x 22" x 6" cushion uses firm, high-density foam (density 1.55, 34 lb compression) bonded to a layer of polyester batting and finished with a washable cover. Designed for easy installation and broad compatibility, it expands after unpacking and fits chairs, sofas, benches, RV seats, and more.

How will this cushion restore a sunken sofa?

The firm high-density foam core provides immediate structure so seat bottoms regain their original height and firmness. The polyester batting wrap smooths fabric and eliminates wrinkles, creating a plumper look and a neater silhouette.

• Density 1.55 with 34 lb compression for resilient support
• Bonded polyester batting prevents sagging and puckering
• 6-inch thickness restores standard seat depth and posture

Is the cover easy to clean and maintain?

Yes — the cushion comes with a removable cover secured by a U-shaped zipper so you can take it off quickly. The cover is machine washable, letting you remove dust, pet hair, and spills without replacing the entire insert.

• U-shaped zipper for simple removal and replacement
• Machine-washable fabric saves time on upkeep
• Zippered closure prevents debris from entering the foam core

How long does the cushion last and how soon will it be ready to use?

Constructed from durable high-density foam, this insert can maintain shape and support for many years with normal household use. It ships compressed for compact packaging; allow 24–48 hours to fully expand, and expect longer expansion times in cooler environments.

• Designed durability for an expected lifespan of 7–10 years with proper care
• Compressed shipping: unbox, unroll, cut plastic, and wait 24–48 hours to expand
• Avoid heavy use until fully expanded to ensure correct recovery

What furniture and situations is this cushion suitable for?
