Materials: 1/2 Ikea Lack (small), 2 Ikea Lack (medium), 1 box Ikea Capita (16cm, 4 pcs), glue
Mount Lack one over the other (start with medium Lack). Use little shelves as base, and the other using capita legs as in photo.
You can also use a small Lack under the shelf on the floor to enforce it. (but it’s not necessary if you don’t plan to use it with heavy items).
Use glue or similar between legs and the respective base (and so for capita legs)
if you need more space, you can add another lack (medium or small, depends on your needs).
