Mid Sleeper Beds A mid-sleeper's mattress is similar to the high sleeper, but it's a little lower and has an easier ladder. These beds are great for small children or bedrooms with limited space. Mid-sleepers can be found with a variety of features, such as desks, shelves, and even tents. https://www.bunkbedsstore.uk/products/kidsaw-white-3ft-cabin-bed-with-multi-drawer
