I really think kids and schools vary on what they need and what’s allowed. We live a plane flight away, and a desk chair was considered, but we’d be storing it every summer. That’s probably $65, $70 a summer. Not worth it, we are already storing a ton. Same with a stick vacuum-- if we bought it for $40 on Amazon, we’d be storing it each summer for more. The three luxuries we did get and are storing are: a foam mattress topper, a window fan and a mini fridge. Oh, also a little IKEA cart that gets disassembled and stored in a box with stuff. The school pretty much demanded we get the window fan. Some schools don’t OK the fridge. Really depends. I do agree with snacks (ALWAYS needed), and I’d say bring more chargers than you think you need (they die or get lost and when they need one, they need it NOW; the school store’s don’t work well often) and maybe 2 multi-plug surge protector things. The rest you can kind of order as you need.
