Mid Sleeper Beds A mid-sleeper bed is similar to a high sleeper, however it's lower and usually has a shorter ladder. They are ideal for small children or bedrooms with a limited space. Mid-sleepers can be found with a range of design features, such as shelves, desks and even tents. https://www.bunkbedsstore.uk/products/white-low-sleeper-kids-cabin-bed-with-storage
