Ikea Kallax Hack Instructions

How to hack the Ikea Kallax storage units into a bench with Legheads Barcelona M8

Step 1

Place constructed Ikea Kallax on its side, with the shelves facing out.

Step 2

Place the universal plates flat on the side that will face the floor, in the position where you want legs to go. We would recommend placing the legs on a flat surface and measuring in at least 1 to 1.5 inches in from the side.

Tip #1: Always place on flat surface

Tip #2: Place away from edge to make it stronger. 

Step 3

Put legs in middle for extra support. Mark drill holes, including hanger (middle) hole.

Step 4

Drill pilot holes. 5/64 or 2mm for outside 5/16 or 8mm for inside. Be really careful here not to drill through the other side. If you do, just cover it with a small sticker, no-one will ever see it.

Tip #4: Place tape on your drill bit to show you where to stop drilling, you don’t want to drill through to the shelf

Step 5

Screw plates on. Legheads comes with long screws, they can be used in this hack with no fear of pushing through the other side.

Step 6

Screw in Legheads Barcelona M8 – You can buy them here

Change colours & accessorize to suit your mood

    Hello. What would the total height of the Kallax shelf be after the legs are attached? And could this work as a Banquette for my kitchen table? Used almost daily? thanks

      Hi Katrina,

      Thanks for asking a great question. This is a favorite with ikea hackers for Kallax

      The single Kallax when on its side is 42 cm or 16.5 inches high. Legheads are 15.25 cm or 6 inches high.

      In total in that is 57.25 cm or 22.5 inches

      If you add our Ikea legs to the double Kallax (on its side), which we have done in our home, in total it is 92.25 cm or 36 inches in total height. We recommend securing the double or any other Kallax hack that is higher than the single to the wall for safety.

      You do need to use a t-plate or a furniture leg attachment plate. Our furniture leg attachment plate is completely flat and extra heavy duty. It is 3 mm or 0.12 inches, solid polished stainless steel.

      All the best

    Hello, I am so worried to do this to my kallax as the timber feels so hollow when I knock on it you can hear it’s hollow. I have an image of me trying to move it someday and the legs bending off due to me screwing into hollow wood. Could you confirm how this is possible If unit is hollow. Seems so unstable to even think about adding weight to it if legs are balancing on a screw that’s hanging out In the hollow air🤪thanks in advance

      Hi Amy,

      Thanks for contacting Legheads. The Kallax is hollow, but is sturdy and is thick enough to take the legs and the attachment plates (always use an attachment plate, never screw the legs in directly). You do need to take care when installing them, be gentle, use a hand screw driver not an electric one and don’t over screw. When the screw takes, is fully in and feels firm, just leave it there.

      I have two Kallax hacks set up with Legheads and they work perfectly, we sit on them, we use them as tables and we use them as storage, we move them around frequently and never had any trouble with the legs bending or breaking from the wood. I use 6 legs for each Kallax hack and would recommend the same.

      Follow the video instructions and you should be fine. Please search M8 attachment plates on Amazon in your region to find the attachment plates.

      All the best
