Replacement Cushions for IKEA Sofas — Custom Foam Inserts for Ektorp, Kivik & More

IKEA sofas are built to be re-covered, but the one thing a new slipcover can't fix is collapsed foam. After a few years the seat cushions on an Ektorp, Kivik or Söderhamn flatten out and you sink instead of sit. USCUSHION cuts new high-density foam inserts to the exact size of your IKEA cushions, so the seat feels firm again — for a fraction of the price of a new sofa.

We are not affiliated with IKEA. We make custom foam inserts and cushions built to fit these sofas.

Keep Your Cover, Replace the Foam

Most IKEA owners already know their covers come off and wash. The real problem is underneath. Unzip the cover, send us the measurements, and drop in a new high-density insert cut to size. If your cover is worn too, we make the whole cushion with a YKK zipper.

Typical IKEA Cushion Sizes

• Ektorp — 3-seat is about 85.9″ wide (two seat cushions, each roughly 30–36″ wide), 2-seat about 70.5″. Seat depth about 19¼″, roughly 5″ thick.
• Kivik — 2-seat about 74¾″, 3-seat about 89¾″. Memory-foam seat cushions roughly 27″ wide × 22–23″ deep × 5″ thick.
• Söderhamn — low, deep seat with loose back cushions and high-resilience foam; deep seat cushions cut to your section.
• Discontinued models like Karlstad — no longer sold by IKEA, still made to fit here.

These are typical ranges. Measure your cushion cover seam to seam and enter the numbers below — we cut to the inch.

When an IKEA sofa frame is still solid but the seats have gone flat, a new foam insert restores the whole piece — no new sofa, and often no new cover.

Perfect for:

• IKEA Ektorp sofas where the seat cushions have flattened after years of use
• IKEA Kivik seats that have lost the memory-foam bounce
• IKEA Soderhamn deep seats needing firmer high-resilience foam
• Owners who keep buying new IKEA covers but need to fix the foam underneath
• Discontinued IKEA models (Karlstad and others) no longer supported by IKEA

Order foam inserts only or complete seat cushions, cut to the exact measurements you enter. Also need back cushions? Order a matching seat & back replacement set.
