Mid Sleeper Beds A mid sleeper bed is similar to a high-sleeper but at a lower level and usually with a shorter ladder or staircase. They are ideal for small children or bedrooms with limited space. Mid-sleepers are available with a variety of features, including desks, shelves, and even tents. https://www.bunkbedsstore.uk/products/mid-sleeper-bunk-bed-with-slide-stairs-guardrails
