HOMBYS Memory Foam Couch Cushion Replacement 5x24x27 — High-Density Core, Removable Cover

If your sofa or chair cushions have flattened or lost support, this HOMBYS replacement insert restores shape and comfort without reupholstery. Built from five layers—a firm high-density base, ventilated memory foam, polyester batting and a Dacron fibre wrap—the cushion is engineered to balance durability with pressure-relieving conformity. It ships compressed for compact delivery and regains full volume after 24–48 hours at room temperature.

How does this cushion improve seating comfort?

The insert pairs a firm, high-density foam core with a softer memory foam layer to support hips and spine while reducing pressure on contact points. The ventilated memory foam helps air circulate, preventing heat buildup. The added polyester batting and Dacron wrap smooth the surface for a plump, tailored appearance.

• High-density base foam (density 1.55) provides long-term structural support.
• Ventilated memory foam conforms to body contours to ease pressure points.
• Polyester batting creates a fuller, even look under covers.
• Dacron fibre layer protects fill and preserves shape over time.

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

Measure your current cushion interior dimensions and compare to the listed 5"×24"×27" size before ordering; this product is intended as a direct replacement for cushions with matching dimensions. The insert arrives vacuum-compressed—installation is simple: remove packaging, cut outer plastic, and allow up to two days for full expansion. A U-shaped zipper on the removable cover makes swapping or adjusting a cover straightforward.

• Confirm internal cushion size before purchase for proper fit.
• Expandable foam arrives compressed; allow 24–48 hours to expand fully.
• U-shaped zipper enables quick cover removal and repositioning.
• Hand-stuff or slide into existing cushion shell as needed.

How do I care for the cushion and cover?

The outer cover is removable and machine-washable, helping keep the cushion fresh and free from dust. The foam core should be kept dry and aired occasionally; avoid placing the foam directly in machine wash. Regular fluffing and rotating extends even wear and preserves the tailored look from the Dacron wrap.

• Remove cover via U-shaped zipper and machine-wash on gentle cycles.
• Do not machine-wash the foam core—air it when needed.
• Rotate cushions periodically to maintain even compression.
• Keep foam away from damp conditions to prevent degradation.

What else can I use this foam insert for?

Beyond sofas and armchairs, the versatile foam insert suits ottomans, window seats, RV and boat benches, car and golf cart seats, bench cushions, and DIY upholstery projects. Its layered construction balances comfort and resilience for many seating or protective padding needs. Because it ships compressed, it’s also convenient for on-the-go reupholstery or replacement jobs.

• Suitable for home furniture: benches, window seats, and stools.
• Great for vehicles: RVs, boats, car and golf cart seats.
• Useful in craft or protective packaging for fragile items.
• Handy for gym benches, cots, and custom upholstered projects.

Who is this for: This HOMBYS cushion replacement is ideal for homeowners, renters, upholsterers, and DIY enthusiasts seeking a durable, supportive upgrade for flattened sofa or chair cushions. It fits anyone who wants a practical, ready-to-install solution that restores seat height and comfort without replacing the entire frame or cover.
