A loft bed would be so much fun. With a cool ladder on wheels would be the best. I like how the one above’s ladder hides a bookcase and so there is double use space for a ladder and your books.

This one is great as it has space on the side for your latest read and the wood is really nice and different.

This one is good for the safety conscious as it’s alot more difficult to roll out forward from your bed.

Alternatively don’t make it a bedroom loft make it a reading loft.
