KIVIK Replacement Cushions for IKEA — Measured Fit (2026)
Cushions to fit IKEA KIVIK: Indoor sofas — big-seat comfort — official measurements, cut to order.
The KIVIK line at a glance
KIVIK is IKEA’s big-seat comfort line – low armrests wide enough to sit on, pocket springs under the seat foam, and a depth (23 5/8 inches) built for naps. It is also one of the best-documented lines for replacements: the product pages publish seat width, depth and height, and the material section names the exact fill – high-resilience cold foam at 2.2 lb/cu.ft over a 2.0 lb/cu.ft polyurethane layer, with fiber-ball backs.
That is everything a rebuild needs. Seats cut to the chart numbers, in the density you choose – the factory spec is the floor, not the ceiling, for a daily-use family sofa.

Measurements compiled from official IKEA product data (live pages, archived official values, or surviving aftermarket spec tables). Inches; metric-derived fractions (22 7/8, 23 5/8) are normal — cut to the fraction, not the rounded inch.

Is your set really KIVIK?
KIVIK frames carry the series name on the frame label and order history; the visual tells are the wide flat armrests and the deep soft seat. Count your seat positions before ordering – the sofa runs one long 70 7/8-inch deck that most owners rebuild as separate blocks (the aftermarket standard is ~24 x 24 x 3 inch cores), which also lets you rotate wear. Full method: our three-step measuring guide.
Fabric options & estimated pricing
Same fit, three fabric tiers — cotton linen (durable everyday), tech fabric (water-resistant, wipes clean), premium velvet (the high-end look that stands up to cat claws). Indoor rebuilds: 45–60D high-resilience cores, thickness chosen to restore the published seat height.
| Piece | Cotton Linen | Tech Fabric | Premium Velvet |
|---|---|---|---|
| Seat block, ~24 x 23 5/8 (per position) | $107 | $112 | $116 |
| Loveseat one-piece bench run (55 1/8 x 23 5/8) | $196 | $206 | $216 |
| Ottoman (35 3/8 x 27 1/2) | $156 | $164 | $172 |
Estimated pricing — $39 make-base + area at per-sq-ft rates, made to order. Final quote confirmed at checkout; welt cord and ties available as add-ons. Covers close with a sewn envelope closure (no zippers on our line).
Measure before you order
Three minutes with a tape measure prevents the classic IKEA mistake — ordering rounded inch sizes for metric fractions. Measure seam to seam, every distinct block, to the nearest quarter inch per our measuring guide; your numbers are cross-checked against the chart above before anything is cut.
Frequently asked questions
What are the seat dimensions of the IKEA KIVIK sofa?
Seat width 70 7/8 in., seat depth 23 5/8 in., seat height 17 3/4 in. – official measurements. The full line’s numbers are in the chart above, piece by piece.
What foam is in KIVIK seat cushions?
High-resilience polyurethane cold foam at 2.2 lb/cu.ft over a 2.0 lb/cu.ft polyurethane layer, on a pocket-spring unit; back cushions are polyester fiber balls. It is honest catalog spec – a rebuild at 45-60D high-resilience foam runs firmer for longer.
Can I replace just one seat block on a KIVIK?
Yes – and it is the smarter pattern. The 70 7/8-inch deck rebuilds as separate ~24 x 23 5/8 blocks; order the set in one run so fabric lots match, then rotate the blocks seasonally to spread the wear.
Do KIVIK sectionals use the same cushion sizes?
Same depth (23 5/8) and height (17 3/4) across the line – widths follow the configuration. Count every distinct block in your assembly and measure each; corner units add their own geometry.
