Mid Sleeper Bunk Mid sleepers are great for children aged four or older, since they are suitable for smaller bedrooms. They offer all the fun and flexibility of a high-sleeper, whilst taking up less floor space. Many cabin beds for mid-sleepers include desks or furniture perfect for homework and study. https://www.bunkbedsstore.uk/products/panana-loft-bunk-bed-3ft-single-grey-color
