Help Holly Sleep Safely

Holly is 4.5. She was born with an undiagnosed condition which has resulted in severe learning disabilities across all areas. She currently has the developmental age of around 6-15months. Holly is a delightful child, full of fun and laughter who's main joy in life is playing one on one with someone. However Holly cannot talk, stand, walk, feed herself or do any other kind of self help. She needs constant supervision and care.
Holly loves to bounce, she always has. She has amazing stomach muscles from not using her arms to help her and as a result can bounce lying down by slamming her feet into the matress. So much so that she can completely leave the bed, head and all. She also likes to throw herself backwards.
Holly is currently in a cotbed but is now outgrowing this and needs a bed where we can use a hoist to help her transfer to a chair, but also to help her be safe at night by having soft inclosed sides to prevent her hurting herself or falling out. The safety sleeper bed will allow is to have this as well as the ability to pack down into its own suitcase to take away. This would give us the ability to go on holiday or visiting family with Hollys twin sister and brother.
