The one I got is from a really old model IKEA, so I don't think you can find an exact one. I recommend shopping around the table section at IKEA since they sell tabletops separately. You can also look for free desks on Facebook Marketplace, then break down the table for what you need. Good luck!
You can try Teflon/Plumbing/ Thread Seal Tape, that is usually used for water piping. It's very thin and you can wrap it around the leg to the thickness that you need. I have not added tape to my legs, since I was able to prevent wobble by pulling each leg outward (pull the left legs left and right legs to the right). This causes the legs to balance each other out.
thank u for video bro. i will buy it for my ikea bed. I will lift my bed little bit, thus when my wife is lying on the bed and I can do dirty things easier. it's adjustable so I will adjust position of my wife :D
