Mid Sleeper Beds A mid-sleeper's bed is similar to a high sleeper, but it's lower and usually has shorter ladders. These are great for younger children or if your bedroom is confined in space. Mid-sleepers can be found with a variety of features, including shelves, desks and even tents. Check https://www.bunkbedsstore.uk/products/molly-midi-sleeper-cabin-bed-single-3ft
