HOMBYS Memory Foam Sofa Cushion Insert 6"x22"x24" – High-Density Support Core, Removable Cover

If your sofa or chair sagged cushions have lost their shape, this HOMBYS replacement insert restores structure, comfort, and a neater appearance without buying a whole piece of furniture. The design pairs a dense support core with a ventilated memory layer and a Dacron-style polyester wrap to reduce wrinkles, increase loft, and improve airflow. A removable, machine-washable cover makes maintenance simple while the compressed packaging expands to full size in 24–48 hours.

How does this cushion deliver both support and comfort?

The insert uses a firm high-density foam core (density 1.55, 34 lb compression rate) for lasting support beneath a ventilated memory-foam layer that conforms to shape and eases pressure points. A polyester batting wrap and Dacron fibre layer keep the cushion looking full and smooth.

• Five-layer construction: support core, memory foam, ventilated channels, polyester batting, and Dacron cover.
• High-density base for structure and durability.
• Memory foam top for contouring and comfort.
• Polyester wrap to maintain loft and reduce fabric wrinkling.

Will it fit my sofa or chair and how do I measure?

Measure the internal dimensions of your cushion cover (length × width × thickness) and compare to the 6" x 22" x 24" size. The insert ships compressed—allow 24–48 hours (longer in cool conditions) to fully expand after removing packaging.

• Measure inside the cushion cover for accurate fit.
• Match thickness to avoid overstuffing or loose fit.
• Allow 24–48 hours for full expansion; avoid cutting the foam before full recovery.

How easy is cleaning and maintenance?

The insert includes a removable cover with a U-shape zipper for quick removal; the cover is machine-washable so you can keep seating fresh without replacing the fill. The foam interior should be spot-cleaned and kept dry to maintain performance and lifespan.

• Removable zipper cover for machine washing.
• Spot-clean foam only; air-dry completely before reinserting.
• Fluff and rotate periodically to maintain even wear.

What can I use this cushion for besides a couch?

These versatile inserts work for chairs, ottomans, window seats, RV and boat seating, car or golf-cart seats, workout benches, and more—any application that needs a supportive, shaped cushion. The durable, multi-layer interior adapts to both residential and mobile environments while resisting quick flattening.

• Suitable for sofas, chairs, ottomans, and benches.
• Good for RVs, boats, car seats, and golf carts.
• Also useful as protective padding in carrying cases for fragile items.

Who is this for? This HOMBYS cushion insert is ideal for homeowners, renters, or hobbyists who want to refresh existing furniture without reupholstering. Choose it if you need firmer support, a neater cushion profile, or a simple, washable cover—especially when you want a practical, long-lasting upgrade for sofas, chairs, or mobile seating in RVs and boats.
