how to put up a floating lack shelf

lacklisa who previously submitted this hack, sent me a link to her “how-to-install-a-floating-lack-shelf” instructions. it’s not a hack, but i’ve decided to post it because it’s just so useful.

“i bought the ikea lack shelf a few years ago and i was freaked when the box didn’t come with the shelf hardware. i had no idea what to use to put it up securely. a search on the internet had not helped, there were loads of horror stories of shelves crashing in the middle of the night and precious belongings being ruined. so when i finally did take on the task, i decided i was going to document it so i could help someone else. here is that post on my blog, feel free to use it if you think it can help your readers.”

thanks, lisa.

    The link to the article is dead. The link has moved to

  2. I have had to resort to cutting a hole in the wall and hammering flexible wood into the cavity for the shelves to get a good hold. it is still pretty difficult to get them perfectly level and aligned, I do not have any problems with the larger Lack shelves that come with the brackets. I don’t know why for the love of god Ikea did not make such brackets for the small lack shelves as trying to get them level is nearly impossible, if they had brackets for them you could just make sure the brackets are level and to the wall then slot the shelves on and hey presto.

    Warning – I just destroyed my wall trying to remove the Lack wall shelf I bought around 2006.
    The screws were easy enough to take out but they mounted inside the wall in little “tubes” (sorry,I’m no carpenter and don’t know the correct term). These tubes have three prongs that spread out as the screw is inserted, acting as a brace. The only way to get the “tubes” out was to rip them out of the wall, which left gapping holes and broken drywall. A real mess. Why would Ikea design such a stupid means to secure this shelf to the wall?

    Since I’m on the topic of Ikea, I would dissuade anyone from buying an inexpensive Ikea chest of drawers. The bottoms pop out and they invariably fall apart after a year or two.

      Your comment is based on zero knowledge and experience.

      The “tubes” are Plastic Wall Anchors. They are not designed by Ikea, they are standard across the entire Construction industry.

      Depending on the weight requirements of what you are hanging and the wall material you must use a specific type of Wall Anchor.

      It’s not stupid. It’s assumed that you know the wall could be damaged by ripping it out. Not really relevant considering a hole will be there.

      Tap the anchors with a ballpene hammer till they are just below the surface, fill the indentation with LePage nail hole filler, sand when dry and repaint.

    Also no one in this article has referred to the smaller width Lack Shelves. the 30 x 26 cm, version.
    I am having trouble figuring out which screws to use; as the screw heads determine how loosely the shelf fits the wall. I was going with flat heads in as in the picture in the manual, but the shelf slopes down.
    I am pretty sure my local tool shop guys are inept as the Ikea manuals, so would appreciate some hacker advice.

      I’ve got the same problem with the small lack shelves. Should they come with a mounting bracket or not?

    • yrnamehere says:

      I know this is months and months later, but in case anyone in the future needs an answer to the question: if you look at the back of the 30 x 26 shelf, the hole for the mounting screw is wide on one end and narrows to a point on the other. Make sure you install the shelf with the narrow side up. Whatever kind of screws you use, make sure they fit in the wide part of the hole. Put your screws into the wall, mount the shelf and then give it a few whacks on the top back edge with a rubber hammer or the Ikea hammer with the plastic cap in the end. That will force the tops of the screws up into the narrow part of the mounting bracket and the shelf should feel locked to the wall. The whacking should move the shelf down about an inch so keep that in mind when you put the screws into the wall. The shelf should feel very solid, but if you decide to take it down or move it, just give it a few whacks on the bottom inside edge and that should unlock it by getting the tops of the screws back down to the wide part of the bracket and you should be able to lift the shelf right off the wall.

    Has anyone put up a Lack shelf on lath and plaster walls? Most of the posts I’ve read about installation refer to drywall or concrete. I have three of the long ones to go behind my sofa. Does anyone know what type of fasteners to use? The more I read online the more confused and nervous I become about embarking on this project! Thanks!

    i bought some lack shelves at ikea and am now trying to increase the depth of the shelves to fit my space. I’m thinking of attaching 2X2 cleats to the wall first, then just attaching the lack shelves to the cleat, then using finished boards of the proper depth to cover the top. Any advice would be greatly appreciated.

    took me forever- the piece that was screwed into the wall has arms that stick out into the shelf. there are screws that go through the bottom of the shelf into these arms. now if only i can get this wall bracket to come out.

    I’d like to know how to remove Lack shelves. It seems impossible.
