ᐅ After rearranging, my KALLAX shelf never sits completely flush against the wall—any ideas?

Hello!
Regarding your question about the soft floor: A carpet cushions and significantly affects stability. The carpet acts like a spring, which can cause a rocking motion. This means that the shelf will naturally lean slightly away from the wall at the back, even if the wall and floor are perfectly level.

About the adjustable feet: IKEA actually offers the "LURÖY" feet or the "Ekby" series, which can also be fitted to KALLAX to compensate for unevenness. Some IKEA enthusiasts also recommend placing felt furniture pads under the feet if you want to avoid scratches.

Good luck!

I would add: In addition to adjustable feet, small wedges or rubber buffers can also help minimize gaps. Simply placing them underneath often easily resolves minor spacing issues.

Thanks for all the tips so far! Today I set up the shelf without the carpet, and it is indeed closer to the wall now, but still not perfectly flush; there remains a tiny gap of about 2-3 mm (0.08-0.12 inches).

That sounds interesting—how did you attach the wood? With screws, glue, or double-sided tape? And are there specific dimensions or materials you would recommend to avoid damaging the back panel?

I don’t want to damage it in case I want to rearrange it later.

I would recommend avoiding screws to prevent damaging the back panel. Instead, thin wooden strips (e.g., spruce wood 5x10 mm (0.2x0.4 inches)) and double-sided mounting tape are suitable, as the tape adheres strongly but can be removed relatively cleanly.

Alternatively, there are special plastic furniture wedges that can be glued to the back, which then protrude slightly to adjust the spacing. Important: Clean the back panel thoroughly before attaching, so the adhesive sticks better.

A 2–3 mm (0.08–0.12 inch) gap is quite normal if the wall isn’t perfectly flat. Some people place small rubber or felt strips behind the back panel to protect the shelf’s rear and to compensate for the space.

One brief note: To ensure the shelf is not only visually flush with the wall but also secure and stable, it is important to check whether the shelf is tip-resistant. Especially if there is a gap between the wall and the shelf, fastening it with screws or attaching brackets to the wall could be considered—even though the KALLAX normally does not require wall mounting.

If the gap can remain minimal for aesthetic reasons and no stability issues arise, using wooden strips or adhesive felt pads is sufficient.

That's exactly what I did! Double-sided tape is really great; it allows me to take the shelf down at any time without much effort.

I used simple wooden strips from the hardware store, brown spruce wood about 1–2 mm (0.04–0.08 inches) thick and 10 mm (0.4 inches) wide. It holds really well and makes the shelf much more stable right away.

Good luck, you can do it! 🙂
