Mid Sleeper Beds A mid-sleeper bed is similar to the high sleeper, however it's lower and usually has a shorter ladder. These are great for younger children or if your bedroom has limited space. Mid-sleepers are equipped with a variety of versatile design features like desks, shelves, or even tents. https://www.bunkbedsstore.uk/products/white-low-sleeper-kids-cabin-bed-with-storage
