I found a great way to fix cheap Ikea furniture. One of the problems with buying Ikea furniture is that it is often quite fragile. The dowels and the screws they give you to put together the furniture is bound to fall apart. The joints just won't hold when put together with this cheap solution.
I have a table I bought from Ikea. Despite the fact that it was one of the more expensive pieces that they have, it too suffered from the "Ikea Wobble". I've own this table for well over 4 years and have never been able to tighten the joints tight enough to prevent it from wobblign. Sick of this, I decided to try and fix it. So I bought this glue called Gorilla Glue. It works great. I used it on all the joints of the table and now the thing is sturdy as a rock.
