Nearly all of these don't really look like the hacks I was imagining; this is mostly just interior decorating (like putting a lot of mirrors on a wall) and putting your shoes under a dresser.
Wow. They didn't put the LackRack in. Homelabs mustn't be photogenic enough.
(Though to be fair, neither of the above suit the aesthetic Ikea like to promote)
This is awesome. So resourceful
A hack I found is they sell a wooden shelving unit whose shelf boards are sold at Home Depot for less than half the price, just without predrilling or hardware. (If you can buy a cheap corded drill and a hand saw, you can make just about any basic structure from DIY plans online)
Not quite the kind of hack IKEA would want to call attention to.
