Mid Sleeper Beds A mid-sleeper bed is similar to a high-sleeper but at a lower level and usually with an easier ladder or staircase. These are perfect for young children or bedrooms with limited space. Mid-sleepers have a variety of versatile design features such as desks, shelves or even tents. https://www.bunkbedsstore.uk/products/solid-pine-naples-bunk-bed-with-underbed-storage
