Can you make one cushion for Kallax units placed side by side?

Two cube shelves under a window. One seat. The cushion follows the run, not the units.

The quick answer

One Kallax window seat cushion can span units placed side by side: measure the whole run and the cushion is made to that length. A single Kallax banquette cushion was made at 15 3/8 x 57 5/8 in (39 x 146 cm). A 4-cube unit plus a single cube under a window took one cushion 15 3/8 x 74 3/8 in (39 x 189 cm).

The first question: one unit, or two?

A buyer in the US wanted kitchen banquette seating on a single Kallax. The cushion was made to the top exactly, 15 3/8 x 57 5/8 in (39 x 146 cm), in the fabric and color chosen.

Another buyer had a four-cube unit and a single cube side by side under a window. One cushion covered both: 15 3/8 x 74 3/8 in (39 x 189 cm). The line between the units disappears under it.

Then: where exactly do I measure?

Across the tops. End to end over every unit in the run, then front to back. Both cushions above share one depth, 15 3/8 in (39 cm). Only the length changed.

Send the length, the depth and your fabric. Custom lengths are quoted one by one from those numbers. The Kallax bench sizes Pattern lists the tops unit by unit, and the Kallax cushion atlas shows finished seats.

Last: can it be any color?

Yes. Any fabric and color from the charts. A window seat sits in daylight all day, so read how sun through glass treats fabric before you choose. More finished runs are gathered in Kallax bench builds.

How long is your run, end to end?

Measure the run. Keep the depth. Let one cushion close the gap.

One Kallax window seat cushion can cover a four-cube unit and a single cube together: 15 3/8 x 74 3/8 in, made to the measured run.

Questions buyers ask next

Do two Kallax units side by side need two cushions?

No. Units placed side by side can share one cushion made to the whole run. Measure end to end across all the tops, then front to back; a four-cube unit plus a single cube took one 74 3/8 in (189 cm) cushion.

How deep is a Kallax seat cushion?

Two past Kallax cushions were both 15 3/8 in (39 cm) deep, the depth of the top. Measure yours anyway before ordering, because a made-to-measure cushion is cut to the numbers you send.

Can a Kallax cushion work as kitchen banquette seating?

Yes. One Kallax became kitchen banquette seating with a cushion made to its 15 3/8 x 57 5/8 in (39 x 146 cm) top. The same method works for a window seat: measure the top and send the numbers.
