I’ve seen a few people have made wooden boxes for under seat storage and even loackable metal ones. I just wanted something to stop everything flying around and thought this worked pretty well. 600 x 400 x 230 euro stackable box. Cut a small notch to clear the under seat frame and stretched a bungee across the front to stop it sliding out. If you go for a 200 high box it’ll slide right under the seat from the back too and doesn’t need a notch, but I will have a mid bulkhead soon so happy it sit against the frame and doesn’t do that. screwfix sell a 200 high box, otherwise most sellers do taller than 200 like this one, that I happened to have in the loft.
If you buy a new box they are £20-25 from what I’ve seen, and you can get different colours.
