Please help kris to get a specialist bed he needs

My son Kris is 12 years old and needs a specialist bed which would help him and us as a family massively. As some may know he hardly sleeps, even with medication.  I have to lay next to him whilst he lashes out. On bad nights I end up covered in bruises with his unintentional thrashing about and sometimes he hurts himself by head butting and biting .  Some days we go 24 hrs without sleep. 
This bed while allow him to have time on his own safely, sleep on his own ( he’s a teenager soon and strong) and I know he will be safe as it’s all padded with strong specialist fabric, and It will help  him feel safe and secure.
As a family I can lay in my bed next door read a book and spend time with his siblings who miss out at bed time. 
kris has severe autism and can’t explain his emotions and attends a local special needs school.  Please help Kris get a comfortable safe bed 
Thank you very much we will hold further fundraising activities to help with this
