ANTILOP Replacement Cushions for IKEA — Measured Fit (2026)

Cushions to fit IKEA ANTILOP: Indoor kids — the flat-pack high chair — official measurements, cut to order.

The ANTILOP line at a glance

ANTILOP is the flat-pack high chair – a one-piece molded seat shell on four detachable steel legs, sold for around twenty-five dollars and in more nurseries than any other chair IKEA makes. The shell has no padding at all: the official accessory line is a $9.99 inflatable supporting cushion and a washable cover, which is enough for a baby who has just learned to sit, and nothing for the years after.

The seat is 9 7/8 by 8 5/8 inches – smaller than any universal baby cushion on the market is cut for. That fraction is the reason this page exists: a padded replacement that actually fits this shell is a custom cut, and a foam insert holds up years past the inflatable.

ANTILOP cushion sizes — full chart

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 ANTILOP?

ANTILOP is unmistakable – one smooth white plastic shell, rounded corners, four curved steel legs that pop off for storage, usually with the round tray attached. The measuring check: seat under 10 by 9 inches is ANTILOP territory, and no universal cushion is cut that small. If yours reads 15 3/4 wide instead, check whether you have the sister junior-chair generation before ordering. 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.

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

Can you buy a replacement cushion for an IKEA ANTILOP high chair?

IKEA sells an inflatable supporting cushion with a washable cover ($9.99) as the official accessory – comfortable for a baby who has just learned to sit, but an air bladder, not a seat. A foam cut to the 9 7/8 x 8 5/8 shell is the durable replacement, in any fabric tier.

What size cushion fits the ANTILOP high chair?

The seat shell measures 9 7/8 inches wide by 8 5/8 deep with the seat surface 21 1/4 off the floor – official measurements. Universal baby cushions start around 13 x 13 and pool visibly on this shell; the fit is a custom cut to the fraction.

Is the ANTILOP cushion machine washable?

The official accessory’s cover is (60 C wash). For a custom cut, the fabric tier decides: cotton linen and tech fabric covers unzip and machine wash; the foam core itself is spot-clean only – same as every cushion on this site.

My child is past the supported-sitting stage - is a cushion still worth it?

That is the most common upgrade reason. The shell is bare plastic; a thin (1 1/2 in.) firm core makes the chair usable through the toddler years, and the detachable-legs design means the frame outlasts several children’s worth of cushions.
