https://a.co/d/05auEwAx These square wire panels are your solution. Buy a bunch of these and a pack of zipties and just make a perimeter around your bed. Specific brand doesnt matter, but I like the black ones since they blend into the background easier and dont stand out. They are also infinitely re-purposable since you can zip em together however you like. Hope this helps. Let me know if you have further questions.
