Mid Sleeper Bunk Mid sleepers are ideal for children aged four and older, since they are suitable for smaller bedrooms. They provide the same enjoyment and flexibility as a high-sleeper, but take up less space. Many mid-sleeper cabin beds include furniture or desks, which are ideal for homework and studying. https://www.bunkbedsstore.uk/products/vonhaus-white-mid-sleeper-bunk-bed-single
